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 .
DETAILED ACTION
Claims 1-14 are presented for examination.
Notice for all Patent Application as subject to AIA
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
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 should not be negated by the manner in which the invention was made.
This application is currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 1-14 are rejected under AIA 35 U.S.C. 103 as being un-patentable over Zhu et al (U.S. Patent Application Publication No. 2023/0377244 A1) in view of Faulkner et al (U.S. Patent Application Publication No. 2023/0388357 A1).
As to claim 1, Zhu et al teach a method for rendering a live video stream in a cloud rendering system (see abstract, figures 1-2, par. 0055), comprising: obtaining, at a cloud server of the cloud rendering system, effect identification information and a live video stream corresponding to virtual reality live streaming, the effect identification information being identification information of a target effect for rendering the live video stream, wherein the cloud rendering system comprises the cloud server and a virtual reality device; determining, at the cloud server, a rendering mode corresponding to the target effect based on the effect identification information (figure 2, pars. 0056-0060, 0073-0074, 0083-0084, 0091-0092, 0096-0097, reference teaches that the cloud server obtaining the avatar and the video stream and performing rendering process).
However, Zhu et al do not disclose that the rendering mode comprises a first rendering mode and/or a second rendering mode and also do not teach that performing rendering process based on the rendering mode.
Faulkner et al teach a method for rendering a live video stream in a cloud rendering system (see abstract, pars. 0003-0004), comprising: the rendering mode comprises a first rendering mode and/or a second rendering mode; in accordance with a determination that the rendering mode is a first rendering mode, performing, at the cloud server, effect algorithm processing based on the live video stream and the effect identification information, performing effect rendering processing based on an identification result corresponding to the effect algorithm processing to obtain a target video stream, and sending the target video stream to the virtual reality device, and obtaining and playing, at the virtual reality device, the target video stream sent from the cloud server; and in accordance with a determination that the rendering mode is a second rendering mode, performing at the cloud server, effect algorithm processing based on the live video stream and the effect identification information and sending the live video stream and an identification result to the virtual reality device, and performing, at the virtual reality device, effect rendering processing based on the live video stream and an algorithm result to obtain a processed target video stream, and playing the processed target video stream (figure 1s, pars. 0027 & 0031, figures 4s, pars. 0041-0042, 0044-0047, 0050-0051, reference teaches that rendering a live video stream in a rendering system and performing rendering process based on the rendering mode).
It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to incorporate the teaching of Faulkner et al as stated above with the method of Zhu et al for performing rendering process based on the rendering mode because it would have provided seamless transition from a VR device to a network device and vice versa during gathering events.
As to claim 2, Zhu et al teach that obtaining, at the cloud server, target data for rendering the target effect in a preset configuration platform based on the effect identification information; determining, at the cloud server, a target rendering area corresponding to the target effect based on the target data; and performing, at the cloud server, an identification operation on the live video stream to obtain an identification result corresponding to the live video stream, wherein the identification result comprises key point information corresponding to the target rendering area in a live image frame corresponding to the live video stream and depth data corresponding to the live image frame (figure 3, pars. 0073-0076, obtaining an avatar based on storage path information and performing rendering process).
As to claim 3, Zhu et al teach that performing, at the cloud server, a rendering operation on the live video stream based on the identification result and the target data to obtain a rendered video stream; and performing, at the cloud server, an encoding operation on the rendered video stream to obtain the target video stream (figure 4, pars. 0083-0090, obtaining a driven avatar and performing rendering process using RTT technology).
As to claim 4, Zhu et al teach that obtaining, at the cloud server, target data for rendering the target effect in a preset configuration platform based on the effect identification information; determining, at the cloud server, a target rendering area corresponding to the target effect based on the target data; performing, at the cloud server, an identification operation on the live video stream to obtain an identification result corresponding to the live video stream, wherein the identification result comprises key point information corresponding to the target rendering area in a live image frame corresponding to a live video stream and depth data corresponding to the live image frame; and performing, at the cloud server, an encoding operation on the live video stream, the identification result and the target data to obtain the target video stream, and sending the target video stream to the virtual reality device (figure 2, pars. 0055-0063, figure 5, pars. 0090-0096, performing rendering process, generating and updating the rendering result, and forwarding to the VR device).
As to claim 5, Zhu et al teach that obtaining, at the virtual reality device, the target video stream, and performing a decoding operation on the target video stream to obtain a live video stream corresponding to virtual reality live streaming, target data and an identification result corresponding to the live video stream, wherein the identification result comprises key point information corresponding to the target rendering area in a live image frame corresponding to the live video stream and depth data corresponding to the live image frame; and performing a rendering operation on the live video stream based on the identification result and the target data to obtain a processed target video stream (figure 2, pars. 0055-0063, figure 5, pars. 0090-0096, performing rendering process, and generating and updating the rendering result).
As to claims 6-10, they are also rejected for the same reasons set forth to rejecting claims 1-5 above, since claims 6-10 do not teach or define any new limitations than above rejected claims 1-5.
As to claims 11-14, they are also rejected for the same reasons set forth to rejecting claims 1-5 above, since claims 11-14 do not teach or define any new limitations than above rejected claims 1-5.
