Abstract: Aspects of the subject disclosure may include, for example, a method that includes obtaining, by a processing system including a processor, video frames over a network; the processing system uses a machine learning algorithm to identify in each frame a first region comprising a natural image and a second region comprising a synthetic graphic image. The processing system separates the natural image from the synthetic graphic image to generate a natural video and a graphics video, encodes the natural video, and processes the graphics video to generate instructions for rendering graphic images at a client system. The client system performs a decoding procedure for the encoded video, a rendering procedure for client-side graphics in accordance with the instructions, and a compositing procedure to obtain a presentable video stream including the natural image and a client-side graphic corresponding to the synthetic graphic image. Other embodiments are disclosed.

Abstract: The present teaching relates to method, system, medium, and implementations for rendering a moving object. An object data package related to a moving object appearing in a monitored scene with respect to a first time instance is first received and features characterizing the moving object at the first time instance are extracted from the package, that are estimated at a monitoring rate and include a current position of the object and a current motion vector at the first time instance. Information associated with a previously rendered object at a previously rendered position at a previous time instance is retrieved and a next rendering position of the object is determined based on the current position, the current motion vector, and a rendering rate lower than the monitoring rate. The object is rendered at the next rendering position based on a motion vector and the information associated with the previously rendered object.

Abstract: Techniques for encoding a binary prediction vector for predicting a palette for palette-based video coding is described. In one example, a method of decoding video comprises receiving an encoded binary prediction vector for a current block of video data, decoding the encoded binary prediction vector using a run-length decoding technique, generating a palette for the current block of video data based on the binary prediction vector, the binary prediction vector comprising entries indicating whether or not previously-used palette entries are reused for the palette for the current block of video data, and decoding the current block of video data using the palette.

Abstract: The techniques introduced here include a system and method for transcoding multimedia content based on the results of content analysis. The determination of specific transcoding parameters, used for transcoding multimedia content, can be performed by utilizing the results of content analysis of the multimedia content. One of the results of the content analysis is the determination of image type of any images included in the multimedia content. The content analysis uses one or more of several techniques, including analyzing content metadata, examining colors of contiguous pixels in the content, using histogram analysis, using compression distortion analysis, analyzing image edges, or examining user provided inputs. Transcoding the multimedia content can include adapting the content to the constraints in delivery and display, processing and storage of user computing devices.

Abstract: In one embodiment, there is provided a moving image decoder for decoding a compression-coded moving image stream. The decoder includes: a deblocking filter configured to perform deblocking filter processing on each of frames to be decoded; a load detector configured to detect a magnitude of internal processing loads occurring inside a video player, including a processing load for decoding; a determination module configured to determine whether to bypass the deblocking filter processing, depending on the magnitude of the internal processing loads. The deblocking filter is configured to bypass the deblocking filter processing, if the magnitude of the internal processing loads is bigger than a threshold value and a processing subject block of the frame is decoded using inter-view prediction.
