    摘要: Scalable video coding and multiplexing compatible with non-scalable decoders is disclosed. In some embodiments, video data is received and encoded in a manner that renders at least a base layer to be compatible with a non-scalable video encoding standard, including by assigning for at least the base layer default values to one or more scalability parameters. In some embodiments, video data is received and encoded to produce an encoded video data that includes a base layer that conforms to a non-scalable video encoding standard and one or more subordinate non-scalable layers, which subordinate non-scalable layers do not by themselves conform to the non-scalable video encoding standard but which can be combined with the base layer to produce a result that does conform to the non-scalable video encoding standard, such that the result can be decoded by a non-scalable decoder. An identification data identifying those portions of the encoded video data that are associated with a subordinate non-scalable layer is included in the encoded video data.

    摘要: A method and system are provided for decoding coded video data by turning off or not loading at least one functional unit or functional subunit of the decoder while decoding a portion of the coded video data. A schedule may be created prior to substantive decoding and then the schedule may be used to decode coded video data. The coded video data may be reordered based on the functional units or subunits the portions of the coded video data need for decoding. The portions of the coded video data are reordered into their original order in an output buffer after being decoded. The decoder may determine which functional units or subunits are needed for decoding based on administration information included with the coded video data. The decoder may decode portions of the coded video data in parallel.

    摘要: Embodiments of the present invention provide a control system for video processes that selectively control the operation of motion stabilization processes. According to the present invention, motion sensor data indicative of motion of a mobile device may be received and processed. A determination may be made by comparing processed motion sensor data to a threshold. Based on the determination, motion stabilization may be suspended on select portions of a captured video sequence.

    摘要: Disclosed is a system and method of controlling a video decoder, including a reviewing channel data representing coded video data generated by an encoder to identify parameters of a hypothetical reference decoder (HRD) used by the encoder during coding operations. A parameter representing an exit data rate requirement of a coded picture buffer (CPB) of the HRD is compared against exit rate performance of the video decoder. If the exit rate performance of the video coder matches the exit rate requirement of the HRD, the coded video data is decoded, otherwise, a certain decoding degradation scheme can be applied, including disabling decoder from decoding the coded video data.

    摘要: Systems, apparatuses and methods whereby coded bitstreams are delivered to downstream end-user devices having various performance capabilities. A head-end encoder/video store generates a primary coded bitstream and metadata for delivery to an intermediate re-encoding system. The re-encoding system recodes the primary coded bitstream to generate secondary coded bitstreams based on coding parameters in the metadata. Each secondary coded bitstream is matched to a conformance point of a downstream end-user device. Coding parameters for each conformance point can be derived from the head-end encoder encoding original source video to generate the secondary coded bitstreams and extracting information from the coding process/results. The metadata can then can be communicated as part of the primary coded bitstream (e.g., as SEI) or can be communicated separately. As a result, the complexity of the secondary coded bitstream is appropriately scaled to match the capabilities of the downstream end-user device to which it is delivered.

    摘要: A video coder employs techniques for applying frame rate adaptation and variable resolution adaptation in response to environmental coding factors present at the coding terminal. According to such techniques, a coder may estimate a coding quality level to be applied based on the environmental coding factors. The coder may retrieve from a controller table, settings for resolution and frame rate based on the estimated quality level. Optionally, the coder further may retrieve settings identifying a range of quantization parameters that may be used during coding. Prior to coding, the coder may configure input video data to match the resolution and frame rate settings retrieved from the controller table. Thereafter, the coder may code the reconfigured input video data by motion-compensation prediction constrained, as applicable, by the retrieved quantization parameter range.
