Abstract: An encoder encodes pixels representative of a picture in a multimedia stream, generates a first approximate signature based on approximate values of pixels in a reconstructed copy of the picture, and transmits the encoded pixels and the first approximate signature. A decoder receives a first packet including the encoded pixels and the first approximate signature, decodes the encoded pixels, and transmits a first signal in response to comparing the first approximate signature and a second approximate signature generated based on approximate values of the decoded pixels. If a corrupted packet is detected, the multimedia application requests an intra-coded picture in response to the first approximate signature differing from the second approximate signature. The second signal instructs the decoder to bypass requesting an intra-coded picture and to continue decoding received packets in response to the first approximate signature being equal to the second approximate signature.

Abstract: A method, system, and computer program product that exploits motion hints associated with rendered video frames. These motion hints are provided to a video encoder to guide a motion-compensation prediction process performed by the video encoder. Specifically, these motion hints can be used to better position a search window in a reference video frame to better capture the motion of a block of pixels in the reference video frame. Because the search window is better positioned in the reference video frame, the memory required to perform the encoding process can be reduced without sacrificing the level of encoded image quality.

Abstract: The present disclosure is directed a system and method for exploiting camera and depth information associated with rendered video frames, such as those rendered by a server operating as part of a cloud gaming service, to more efficiently encode the rendered video frames for transmission over a network. The method and system of the present disclosure can be used in a server operating in a cloud gaming service to improve, for example, the amount of latency, downstream bandwidth, and/or computational processing power associated with playing a video game over its service. The method and system of the present disclosure can be further used in other applications where camera and depth information of a rendered or captured video frame is available.

Abstract: A system, method and computer program product to traverse a polygon mesh, partition the polygon mesh into a set of polygon fans based on the traversal order, and tessellate the set of polygon fans into triangles based on the traversal order. This transformation of the polygon mesh into a triangle mesh enables the polygon mesh to be compressed and decompressed using the SC3DMC standard.
