Office Action

§103 §112
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Response to Amendment / Arguments Applicant’s arguments have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Claim Objections Claim 12 is objected to because of the following informalities: in the third to last line, “depending the” should be changed to “depending on the”. Appropriate correction is respectfully required. Claim Rejections - 35 USC § 112(a) The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1-4 and 7-14 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Regarding independent claims 1 and 12-14, the written description does not support the following claim language (using claim 1 as an example; same analysis applies to all independent claims): by performing frame-by-frame analysis of video frame continuity using frame sequence identifiers or timestamps including in the video input… wherein the abnormality detection unit determines the abnormality based on a discontinuity in a sequence of the frame sequence identifiers or timestamps between successive frames As a preliminary matter, the independent claims recite a wherein clause (see claim 1) immediately before the above wherein clause with the term “metadata” and a negative limitation, whereby, (1) “metadata” in the wherein clause before the above wherein clause, is also not in the specification, and (2) para. 48 of the specification actually contradicts the prior wherein clause with the negative limitation, so the examiner is respectfully giving wide latitude to what Applicant’s specification does and does not necessarily describe or support. However, the written description does not provide support for the above wherein clause regarding determining the abnormality based a discontinuity in a sequence of frame sequence identifiers or timestamps. The examiner included the “by performing…” claim language since this is where there is antecedent basis for the frame sequence identifiers and timestamps. The words: “frame sequence identifier”, “identifier”, “sequence”, “identify”, “timestamp” and “time stamp” are nowhere present in Applicant’s specification as filed. The examiner searched not just the claim language, but also searched synonyms or similar words (also, “transmission” and “transmit” aren’t in the specification, either. The examiner searched for these two words because the technical definition or a description of “frame sequence identifier” would likely use these two transmission/transmit terms). Here is where Applicant’s specification as filed provides the most support and description for the “abnormality detection unit”, determining an abnormality, on a “frame-by-frame” basis (also recited in claim 1) (emphasis added): [0044] Image data is not missing up to the frame number n-1, and therefore, the video image 2 is selected for the video image output. When it is detected that image data is missing at the frame number n by the abnormality detection unit 270, the video image selection unit 250 switches the video image output to the video image 1. At this moment, the buffer 250a absorbs the timing difference between the video image 1 and the video image 2. Afterward, the video image 1 is selected for the video image output, until there is no missing image data in the video image 2. Here, image data is missing in only one frame, and the video image 2 is selected again for the video image output at the frame number n+1 and subsequent frame number. Examples of the cause of such missing image data in a single frame can include an instantaneous interruption in communication between the first video processing apparatus 20 and the second video processing apparatus 30, and a reduction in frame rate due to a momentary rise in load on the second video processing apparatus 30 side. [0045] In this way, whether image data is missing in the video image 2 input from the second video processing apparatus 30 is detected frame by frame, and the video image 2 is switched to the video image 1 frame by frame. [0046] Fig. 3B illustrates a situation where image data is missing continues at the frame number n and subsequent frame numbers of the video image 2. As shown above in paras. 44-46 of the specification, the most description Applicant respectfully provides in relation to the abnormality detection unit, and “frame-by-frame” analysis, is for image data being missing, which can be the result of an interruption in communication between apparatuses, or a reduction in frame date. None of this describes, supports, or relates to a discontinuity in frame sequence identifiers, or timestamps, as being claimed. Should Applicant disagree, Applicant is requested to point out, respectfully with sufficient specificity, where there is support for the above claim language, and how a description of an interruption in communication, or reduced frame rate, or missing image data (which Applicant’s specification has) [Wingdings font/0xE0] gives support and/or clearly describes an abnormality detected based on a discontinuity in a sequence of frame sequence identifiers or timestamps, as claimed. The remaining claims are rejected based on dependencies. Clarification and correction are respectfully required. Claim Interpretation: 112(f) The following is a quotation of 35 U.S.C. 112(f): (f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph: An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked. As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph: (A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function; (B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and (C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function. Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function. Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function. Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are: “abnormality detection unit” and “video image selection unit” in claims 1-12. Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof. If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 1-4 and 8, 9, and 11-14 are rejected under 35 U.S.C. 103 as being unpatentable over Rodriguez (U.S. Patent App. Pub. No. 2018/0053284 A1) in view of Stahl (U.S. Patent App. Pub. No. 2021/0165229) and further in view of Hetherington (U.S. Patent No. 6,859,456). Regarding claim 1: Rodriguez teaches: a display system (Fig. 2A: 80 a VR/MR/AR display system) comprising: a display apparatus of head-mounted type (Fig. 2A: the head mounted glasses, or para. 198: HMD or headset); a first video processing apparatus including a first computer graphics (CG) generation unit that generates CG (Fig. 2A: 70, local processing module, in combination with para. 198, the local processing module includes a computer vision processor), and configured to output a display-purpose video image to the display apparatus (para. 172, the image generating processor can generate virtual content to be displayed to the user. In one non-limiting example, the processor may convert an image or video associated with the virtual content to a format that can be projected to the user in 3D. For example, in generating 3D content, the virtual content may need to be formatted such that portions of a particular image are displayed at a particular depth plane while others are displayed at other depth planes. This teaches outputting a “display-purpose video image” to the display apparatus. Also, the examiner is interpreting the “image generating processor” of para. 172 to correspond to one embodiment of the “local processing module”, in view of para. 173, which teaches that it can be part of the system (local) or external); and a second video processing apparatus including a second CG generation unit that generates CG, and configured to communicate with the first video processing apparatus (Fig. 2A: 72, remote processing module, in combination with para. 207, the remote processing module can have a GPU/CPU configuration and perform image processing for delivery to local processing module. Another example of the communication between local and remote processor is in para. 468, and/or illustrated in Fig. 2A or Fig. 2G), wherein the first video processing apparatus includes: one or more processors (see mapping above, Fig. 2A and para. 198, one or more processors) (alternatively, see Stahl, paras. 53-54, systems or HMD devices with multiple processors (e.g. “a multiprocessor system including several processors (e.g., two, four, eight, or another suitable number)” per para. 54) is known); one or more memories (Rodriguez, para. 168) including instructions stored thereon that, when executed by the one or processors (e.g. Rodriguez, para. 219, executable instructions stored in memory is known) (alternatively, see Stahl, para. 17), cause the video processing apparatus to function as: an abnormality detection unit (at least one aspect of the local processor) that detects an abnormality of a video image input from the second video processing apparatus, or an abnormality of a state of connection with the second video processing apparatus…wherein the abnormality detection is based on discontinuity in the video from metadata and is not based on general network conditions, latency, or playback delay (Rodriguez teaches a controller that can modify image data based on “control data” (e.g. Fig. 10: 1010), for display (see paras. 45-47, 240. Paragraph 240 teaches the controller reading “appended control data” – which corresponds to metadata). The control data can indicate image warping operations to be performed on image data (see para. 246), which is one non-limiting example of detected abnormality of a video image input from the second video apparatus, detected via control data receipt. Other examples of abnormality detection: paras. 82, 263, 370, 457, 462, 463)…, and a video image selection unit (at least one aspect of the local processor) that selects either one of a first video image using the CG generated by the first CG generation unit and a second video image using the CG generated by the second CG generation unit as a video image to be used for the display-purpose video image, depending on the discontinuity detected in the sequence of the frame sequence identifiers or timestamps by the abnormality detection unit (see above abnormality examples, in ones where processor receives control data that indicates modifying images for display, the second video image will be used for the display-purpose video image. In the case of drift as the detected abnormality, the first video image will be used, with the drift issue corrected) (** for the abnormality being FSI or timestamps, see below). Regarding: by performing frame-by-frame analysis of video frame continuity using frame sequence identifiers or timestamps included in the video input from the second vide processing apparatus…wherein the abnormality detection unit determines the abnormality based on a discontinuity in a sequence of the frame sequence identifiers or timestamps between successive frames, consider the following. In analogous art, Stahl teaches that it is known for HMDs to use a previous frame (i.e. first video image generated by first generation unit) in cases where the HMD does not receive an encoded frame (i.e. a missing video frame), or if the encoded frame is incomplete (i.e. abnormalities are detected) (see Stahl, para. 81, 104; an incomplete frame also teaches/suggests a missing frame); and/or, use the previous frame if the current frame (i.e. frame from the second generation unit) is determined to be missing or incomplete (another example of detected abnormality) (para. 82, 105). This also teaches a frame-by frame basis (see also paras. 49, 82, 104 or claim 22). Re: the abnormality being based on a discontinuity in a sequence of frame sequence identifiers or timestamps, Hetherington teaches this with respect to frame sequence identifiers (see claim 1; note RLP data, a refers to RLP, “Radio Link Protocol”, which is a generic reliability protocol for wireless data links that can carry any type of data, including image data). Modifying the applied references, in view of same, such to include frame by frame analysis, per Stahl and Hetherington, whereby abnormality (all three references) is frame by frame (Stahl, Hetherington) and based on FSI or time stamps (Hetherington), is all of taught and suggested by the prior art, and would have been obvious and predictable to one of ordinary skill. It would have been obvious for one of ordinary skill in the art to have modified the applied reference(-s), in view of same, and with or without Stahl, to have included the above, and the results of the modification would have been obvious and predictable to one of ordinary skill in the art as of the effective filing date of the claimed invention. See MPEP §2143(A). Both references are relevant to correction of errors in video frame processing/receiving/display, and one of ordinary skill in the art would have been further motivated to assemble a comprehensive system/method to correct for frame errors prior to display. The prior art included each element recited in claim 1, although not necessarily in a single embodiment, with the only difference being between the claimed element and the prior art being the lack of actual combination of certain elements in a single prior art embodiment, as described above. One of ordinary skill in the art could have combined the elements as claimed by known methods, and in that combination, each element merely performs the same function as it does separately. One of ordinary skill in the art would have also recognized that the results of the combination were predictable as of the effective filing date of the claimed invention. Additional motivation would be to allow for systems to have checks in place to ensure the rendering of desired content. Regarding claim 2: It would have been obvious for one of ordinary skill in the art to have further modified the applied reference(-s), in view of same, to have obtained: the display system according to claim 1, wherein the first video processing apparatus includes a combining unit (Rodriguez, at least one aspect of the local processor) that combines a predetermined video image and CG (Rodriguez, Fig. 33 and “Scene Augmentation” section, beginning at para. 422. This teaches combining a predetermined video image of a 3D scene with CG of, in this example, a character Fig. 33: 2) (see also Rodriguez, para. 426 or claim 1. AR/VR/MR teaches combining predetermined video and CG) (alternatively, Stahl, Fig. 4 and para. 64), wherein the first video image is a video image obtained by superimposing the CG generated by the first CG generation unit on the predetermined video image (see above mapping to Rodriguez, having the external or second processor perform scene augmentation), and wherein the second video image is a video image obtained by superimposing the CG generated by the second CG generation unit on the predetermined video image (see above mapping to Rodriguez, having the external or second processor perform scene augmentation), and the results of the modification would have been obvious and predictable to one of ordinary skill in the art as of the effective filing date of the claimed invention. See MPEP §2143(A). The prior art included each element recited in claim 2, although not necessarily in a single embodiment, with the only difference being between the claimed element and the prior art being the lack of actual combination of certain elements in a single prior art embodiment, as described above. One of ordinary skill in the art could have combined the elements as claimed by known methods, and in that combination, each element merely performs the same function as it does separately. One of ordinary skill in the art would have also recognized that the results of the combination were predictable as of the effective filing date of the claimed invention. Additional motivation would be to share processing between two processing units, and take advantage of extended/alternate reality processing and experiences. Regarding claim 3: Rodriguez and/or Stahl teach: the display system according to claim 2, wherein the second video processing apparatus includes a combining unit (Rodriguez, at least one aspect of the external processor)) configured to generate a composite image by overlaying CG generated by the second CG generation unit onto the predetermined video image using image blending (see mapping to claim 2 re: augmentation) (note: claim interpretation, “combining” the predetermined video with CG corresponds to “superimposing” of the CG and predetermined video, as in claim 2) (alternatively, Stahl, para. 51, overlaying to generate composite images is known),; and wherein the video image input from the second video processing apparatus is a composite image generated by the combining unit (Stahl, para. 51, composite image). Note: claim interpretation [Wingdings font/0xE0] Applicant’s specification as filed does not contain the term “blend” or “blending” in any iteration. The examiner is interpreting the claimed image blending to be redundant, or part of the overlaying to generate a composite image. It would have been obvious for one of ordinary skill in the art, as of the effective filing date of Applicant’s claims, to have further modified the applied references, in view of same, to have obtained the above, motivated to provide extended reality to users and image combinations. Regarding claim 4: Stahl teaches: the display system according to claim 2, wherein the display apparatus includes an image pickup unit, and wherein the predetermined video image is a video image picked up by the image pickup unit (Stahl, para. 10 and Fig. 4: “a method of operation for a mixed reality system in which rendered frames of virtual content received from the base station are composited with frames from the HMD scene cameras on the HMD,” see also claims 29, 35, 40 and para. 30, 40-45, for more teaching. The camera is the “image pickup unit”). It would have been obvious for one of ordinary skill in the art, as of the effective filing date of Applicant’s claims, to have further modified the applied references, in view of same, to have obtained the above, motivated to provide extended reality to users relevant to their current or surrounding scene. Regarding claim 8: Rodriguez and/or Stahl teach: the display system according to claim 1, wherein the video image input from the second video processing apparatus is the CG generated by the second CG generation unit (see mapping to claim 1; claim 8 is mapped in claim 1, and re-iterates that the input from the second apparatus (as reviewed by abnormality detection unit) is the CG generated by second apparatus, as mapped/recited in claim 1 as part of the functions performed by second apparatus). It would have been obvious for one of ordinary skill in the art, as of the effective filing date of Applicant’s claims, to have further modified the applied references, in view of same, to have obtained the above, motivated to ensure that the correct or proper images/video are displayed. Regarding claim 9: Rodriguez and/or Stahl teach: the display system according to claim 1, wherein the video image selection unit selects the second video image as the display-purpose video image, in a case where no abnormality is detected by the abnormality detection unit (see mapping to claim 1, no changes need to be made, display the input from second apparatus), and wherein the video image selection unit selects the first video image as the display-purpose video image, in a case where an abnormality is detected by the abnormality detection unit (this is an example of a shift abnormality (Rodriguez), or missing/incomplete frames (Stahl). See mapping to claim 1). It would have been obvious for one of ordinary skill in the art, as of the effective filing date of Applicant’s claims, to have further modified the applied references, in view of same, to have obtained the above, motivated to ensure that the correct or proper images/video are displayed. Regarding claim 11: Stahl teaches: the display system according to claim 1, wherein the first video processing apparatus and the second video processing apparatus each include a recording/reproducing unit that records a video image and reproduces a video image (Stahl, para. 39-41 and claim 29, HMD (first apparatus) has a recording unit that records and reproduced; Stahl, para. 59, base station (second apparatus) can be a desktop computer, notebook or laptop computer, pad or tablet device, smartphone, hand-held computing device, any of these include a camera (recording/reproducing apparatus)) using a storage unit (Stahl, para. 55, memory of HMD, to store images captured), and para. 59, the devices of second apparatus (base station) also have memory)). It would have been obvious for one of ordinary skill in the art, as of the effective filing date of Applicant’s claims, to have further modified the applied references, in view of same, to have obtained the above, motivated to make use of known hardware architecture to perform desired tasks. Regarding claim 12: see also claim 1. The features of claim 12 are an alternate embodiment, or similar to those of claim 1, as mapped below; the same rationale for rejection applies: a video processing apparatus (first video processing apparatus of claim 1) configured to output a display-purpose video image to a display apparatus of head-mounted type (claim 1, display apparatus), the video processing apparatus comprising: one or more processors; one or more memories including instructions stored thereon that, when executed by the one or more processors, cause the video processing apparatus to function as (claim 1): a first computer graphics (CG) generation unit configured to generate CG (claim 1); an abnormality detection unit configured to detect an abnormality of a video image input from another video processing apparatus including a second CG generation unit that generates CG, or an abnormality of a state of connection with the other video processing apparatus by performing frame-by-frame analysis of video frame continuity using frame sequence identifiers or timestamps included in the video input from the second vide processing apparatus, wherein the abnormality detection is based on discontinuity in the video from metadata and is not based on general network conditions, latency, or playback delay, wherein the abnormality detection unit determines the abnormality based on a discontinuity in a sequence of the frame sequence identifiers or timestamps between successive frames (claim 1, the “another video processing apparatus” corresponds to the “second view processing apparatus” of claim 1); and a video image selection unit configured to select either one of a first video image using the CG generated by the first CG generation unit and a second video image using the CG generated by the second CG generation unit as a video image to be used for the display-purpose video image, depending the discontinuity detected in the sequence of the frame sequence identifiers or timestamps by the abnormality detection unit (claim 1), Regarding claim 13: see claim 12. The “control method for a video processing apparatus” of claim 13 corresponds to the functions performed by the video processing apparatus of claim 12. The same rationale for rejection applies. Regarding claim 14: see also claims 1 and 13. Rodriguez teaches: a non-transitory computer-readable storage medium storing a program for causing a computer to execute a control method (para. 543) for a video processing apparatus (system of claim 1). The control method for a video processing apparatus corresponds to the control method of claim 13; the same rationale for rejection applies. Claim(s) 7 and 10 are rejected under 35 U.S.C. 103 as being unpatentable over Rodriguez in view of Stahl and Hetherington, and further in view of Dimitrov (U.S. Patent App. Pub. No. 2019/0164518). Regarding claim 7: It would have been obvious for one of ordinary skill in the art to have combined and modified the applied reference(-s), in view of same, to have obtained: the display system according to claim 1, wherein the abnormality detection unit determines that the video image is stopped, in a case where missing in the video image input from the second video processing apparatus continues for a predetermined period, and the results of the modification would have been obvious and predictable to one of ordinary skill in the art as of the effective filing date of the claimed invention. See MPEP §2143(A). Dimitrov teaches a “system …generating image frames associated with the application at a frame rate, and a client which displays the image frames on a display that has a predetermined refresh rate and which monitors arrival times of the image frames in relation to the predetermined refresh rate” (Abstract). Dimitrov teaches that it is known for “stutter” to occur “when writing into the display buffer is delayed with respect to reading according to the refresh rate of the display, and the display reads and redraws stale (already previously displayed) content from the buffer.” (para. 10. See also paras. 62-67). The identification of stutter (paras. 62-67) by Dimitrov teaches Applicant’s claim 7. Modifying the applied refs, in view of Dimitrov, such to include stuttering as an abnormality case (where the missing video continues for a time period), is all of taught and suggested by Dimitrov, and obvious and predictable to one of ordinary skill in the art. One of ordinary skill in the art could have combined the elements as claimed by known methods, and in that combination, each element merely performs the same function as it does separately. One of ordinary skill in the art would have also recognized that the results of the combination were predictable as of the effective filing date of the claimed invention. Additional motivation would be to be aware of and monitor/address issues that can hinder desired frame rate. Regarding claim 10: It would have been obvious for one of ordinary skill in the art to have further modified the applied reference(-s), in view of same, to have obtained: the display system according to claim 1, further comprising a buffer configured to absorb a timing difference when the video image selection unit switches between the first video image and the second video image, and the results of the modification would have been obvious and predictable to one of ordinary skill in the art as of the effective filing date of the claimed invention. See MPEP §2143(A). Dimitrov teaches a buffer that can hold frames prior to display (see para. 66-67). This teaches the buffer of claim 10, to absorb a timing difference when switching between first and second video image (i.e. one that arrives from the second apparatus). Modifying the applied references, in view of same, to have included the buffer capabilities of Dimitrov, such to alleviate timing discrepancies (which all three references are motivated to achieve), would have been obvious and predictable to one of ordinary skill in the art. One of ordinary skill in the art could have combined the elements as claimed by known methods, and in that combination, each element merely performs the same function as it does separately. One of ordinary skill in the art would have also recognized that the results of the combination were predictable as of the effective filing date of the claimed invention.
