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 .
Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claim 20 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claim 20 appears to be directed to a device. However, the body of the claim does not contain any physical structure that would make up said device. The examiner notes that at least one processor and one or more memories are mentioned in the preamble of the claim. To overcome this rejection the Examiner recommends said at least one processor and the one or more memories be present in the body of the claim.
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) 1-5, 8-12, and 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Maegawa et al. (US 2015/0195531) in view of Le Scouarnec et al. (US 2023/0254533).
Regarding claim 1 Maegawa discloses a method for processing video frames, wherein the method comprises:
detecting whether a first video frame is a scene switching frame (acquiring scene change information – [0059]); in response to determining that the first video frame is the scene switching frame, continuing to display a second video frame (a period when the encoded data of the frame image before the scene change is being output may be dynamically configured according to an actual progressing state of the encoding processing on the frame image after the scene change, or may be preset based on a standard processing time of the encoding processing on the intra-frame; outputting the encoded data of the frame image before the scene change to the stream sender for a predetermined number of frames corresponding to the encoding processing time of the intra-frame – [0060-0061]).
However, fails to explicitly disclose switching display from the second video frame to the first video frame based on the first video frame meeting a preset display condition, wherein the second video frame is a video frame that is last displayed before a bitstream of the first video frame is received.
In his disclosure Le Scouarnec teaches switching display from the second video frame to the first video frame based on the first video frame meeting a preset display condition, wherein the second video frame is a video frame that is last displayed before a bitstream of the first video frame is received (the requested BL segment may be received (e.g., decoded and played out) by the receiver and depending on the available bandwidth, the requested EL segment, being transmitted in a lower priority than the requested BL segment, may be timely received, for being decoded and successfully played out by the receiver – [0046]).
It would have been obvious to a person with ordinary skill in the art, before the effective filing date of the claimed invention, to incorporate the teachings of Le Scouarnec into the teachings of Maegawa because such incorporation would yield the predicted result of improving the experience of the user by improving the continuity and quality of the displayed video.
Regarding claim 2 Maegawa discloses the method according to claim 1, wherein the detecting whether a first video frame is a scene switching frame comprises: receiving indication information; and detecting whether the indication information comprises a first identifier, wherein the first identifier indicates whether the first video frame is the scene switching frame (scene change information – [0059]; adding additional information indicating the occurrence of the scene change to the data of the frame image before or after the scene change; any form of the additional information is possible – [0074]).
Regarding claim 3 Maegawa discloses the method according to claim 2, wherein: the indication information is in the bitstream of the first video frame; or the indication information is in a target bitstream, wherein the target bitstream is a bitstream that is last received before the bitstream of the first video frame is received (when the renderer detects the occurrence of the scene change in the generated frame images, it adds additional information indicating the occurrence of the scene change to the data of the frame image before or after the scene change (regardless of before or after as long as it is compatible with a configuration of the scene change detector mentioned later) – [0074]).
Regarding claim 4 Maegawa discloses the method according to claim 3, wherein the first video frame comprises at least one image unit arranged in order, a target image unit is an initial image unit in the first video frame, and the indication information is in a bitstream of the target image unit (frame images – [0057-0061]; intra-frames and inter-frames – [0057-0061]).
Regarding claim 5 Maegawa discloses the method according to claim 4, wherein: the target image unit is an image slice or an image tile; or the target image unit comprises a plurality of image blocks (intra-frames and inter-frames – [0057-0061]; a person with ordinary skill in the art would know that image frames comprises a plurality of image blocks).
Regarding claim 8 Maegawa discloses the method according to claim 1, wherein timing of a target bitstream is later than timing of a bitstream of the second video frame (a period when the encoded data of the frame image before the scene change is being output may be dynamically configured according to an actual progressing state of the encoding processing on the frame image after the scene change, or may be preset based on a standard processing time of the encoding processing on the intra-frame; outputting the encoded data of the frame image before the scene change to the stream sender for a predetermined number of frames corresponding to the encoding processing time of the intra-frame – [0060-0061]).
Regarding claim 9 Maegawa discloses the method according to claim 1. However, fails to explicitly disclose wherein the preset display condition comprises at least one of the following: determining that bitstreams of all image units in the first video frame are received; or determining that the first video frame meets a quality condition.
In his disclosure Le Scouarnec teaches the preset display condition comprises at least one of the following: determining that bitstreams of all image units in the first video frame are received; or determining that the first video frame meets a quality condition (the requested BL segment may be received (e.g., decoded and played out) by the receiver and depending on the available bandwidth, the requested EL segment, being transmitted in a lower priority than the requested BL segment, may be timely received, for being decoded and successfully played out by the receiver – [0046]).
It would have been obvious to a person with ordinary skill in the art, before the effective filing date of the claimed invention, to incorporate the teachings of Le Scouarnec into the teachings of Maegawa because such incorporation would yield the predicted result of improving the experience of the user by improving the continuity and quality of the displayed video.
The Examiner notes claim 9 is written in an alternative form. The Examiner has selected the alternative “determining that bitstreams of all image units in the first video frame are received”.
Claim 10 further limits an alternative limitation not selected by the Examiner. Therefore, the limitations of claim 10 are not being considered.
Regarding claim 11 Maegawa discloses the method according to claim 1, wherein the method further comprises: in response to determining that the first video frame is not the scene switching frame, and after receiving a bitstream of any image unit in the first video frame, displaying a reconstructed image of the any image unit based on the bitstream of the any image unit (when it is not determined that the scene change occurs, the encoder 325 encodes the frame as the inter-frame – [0064]).
Regarding claim 12 Maegawa discloses the method according to claim 11, wherein the first video frame is the scene switching frame, and the method further comprises: for the bitstream of the any image unit in the first video frame: after determining that the bitstream of the any image unit meets a feedback condition, sending feedback information corresponding to the any image unit, wherein the feedback condition is that an amount of enhancement layer image data comprised in the bitstream of the any image unit is greater than or equal to the preset amount threshold (when it is determined that the scene change occurs, the manager controls the encoder, and encodes the frame after the scene change as the intra-frame – [0064]; when the frame after the scene change is encoded as the intra-frame, the manager determines whether or not the encoding is completed in the output timing of the relevant frame; when it is determined that the encoding is not completed, the manager controls and causes the encoder to output the encoded data of the frame image before the scene change to the stream sender – Figure6, [0065-0067]).
Claim 20 corresponds to the device performing the method of claim 1. Therefore, claim 20 is being rejected on the same basis as claim 1.
Claim(s) 6-7 is/are rejected under 35 U.S.C. 103 as being unpatentable over Maegawa et al. (US 2015/0195531) in view of Le Scouarnec et al. (US 2023/0254533) further in view of Aristarkhov et al. (US 2021/0392352).
Regarding claim 6 Maegawa discloses the method according to claim 5. However, fails to explicitly disclose wherein the indication information is in header information of base layer image data of the bitstream of the target image unit, and wherein the header information is at a network abstraction layer corresponding to the bitstream of the target image unit.
In his disclosure Aristarkhov teaches the indication information is in header information of base layer image data of the bitstream of the target image unit, and wherein the header information is at a network abstraction layer corresponding to the bitstream of the target image unit (indicating that a scene change has been assigned to the base layer – [0052, 0061, 0067-0068]; the frame layers and reference assignments may be transmitted with the compressed image data to decoders, whether placed in frame, slice, or other frame partition headers, overhead, between frames, in NAL units of the frames, and/or as metadata being transmitted with the frames – [0055]).
It would have been obvious to a person with ordinary skill in the art, before the effective filing date of the claimed invention, to incorporate the teachings of Aristarkhov into the teachings of Maegawa as modified because such incorporation improves performance and quality (par. 72).
Regarding claim 7 Maegawa discloses the method according to claim 6. However, fails to explicitly disclose the header information is in header information of the network abstraction layer; or the header information is in a subject of the network abstraction layer and is in slice header information of the target image unit.
In his disclosure Aristarkhov teaches the header information is in header information of the network abstraction layer; or the header information is in a subject of the network abstraction layer and is in slice header information of the target image unit (indicating that a scene change has been assigned to the base layer – [0052, 0061, 0067-0068]; the frame layers and reference assignments may be transmitted with the compressed image data to decoders, whether placed in frame, slice, or other frame partition headers, overhead, between frames, in NAL units of the frames, and/or as metadata being transmitted with the frames – [0055]).
It would have been obvious to a person with ordinary skill in the art, before the effective filing date of the claimed invention, to incorporate the teachings of Aristarkhov into the teachings of Maegawa as modified because such incorporation improves performance and quality (par. 72).
