摘要： A sequence of picture slices is encoded as reference slices and non-reference slices, wherein the reference slices include B slices, by forming, for each B slice, at least one data packet containing data values derived from brightness and color information pertaining to the slice. The data packet for each B slice includes a header element indicating whether the B slice is a reference slice. The header element of each reference B slice has a value that depends on depth of the reference B slice in a hierarchy of discardability.

摘要： Input minimal noise levels of are computed over input codeword bins based on image content in input images of an input bit depth. The minimal noise levels are adjusted to generate approximated minimal noise levels of a higher bit depth. The approximated minimal noise levels are used to generate per-bin bit depths over the input codeword bins. The input codeword bins are classified into first codeword bins that have relatively high risks of banding artifacts and some other input codeword bins that have relatively low or zero risks of banding artifacts based on the per-bin bit depths. Portions of bit depths from the other input codeword bins are moved to the first input codeword bins to generate modified per-bin bit depths. A forward reshaping function constructed from the modified per-bin bit depths is used to reshape the input images into reshaped images used to generate output images.

摘要： In one example, a device for coding video data includes a video coder configured to code, for a bitstream, information representative of which of a plurality of video coding dimensions are enabled for the bitstream, and code values for each of the enabled video coding dimensions, without coding values for the video coding dimensions that are not enabled, in a network abstraction layer (NAL) unit header of a NAL unit comprising video data coded according to the values for each of the enabled video coding dimensions. In this manner, NAL unit headers may have variable lengths, while still providing information for scalable dimensions to which the NAL units correspond.

摘要： The present invention provides a method and system to conceal video errors due to lost packets in the transmission without incurring additional bandwidth usage. The present invention is to use current and previous frames to search for similar patches for the corrupted blocks in the current frame. The search process speed for locating the lost packets is significantly improved by incorporating a smart search concept. The concealment algorithm of the present invention can be implemented in GPUs and multi-core CPUs.

摘要： In an example, a method of coding video data includes coding one or more non-video coding layer (VCL) network abstraction layer (NAL) units of a layer of a multi-layer bitstream of video data, where the one or more non-VCL NAL units contain an SEI message having an SEI payload type. The method also includes determining one or more syntax values of the multi-layer bitstream to which the SEI message applies based on the SEI payload type.

摘要： A method of encoding data on single level or variable multi-level cell storage includes receiving a block of encoded data from an approximation-aware application and at least an importance attribute associated with the block of encoded data; and assigning the block of encoded data to a memory address or a particular region of a memory having at least three precision levels, based at least according to the importance attribute. The importance attribute indicates a relative sensitivity of bits of the block to errors in an output quality from decoding the encoded data. An approximation-aware application can be an image encoding application having a modified entropy encoding step that enables identification and splitting of bits into groupings according to sensitivity to errors.

摘要： A method and a signal processor for receiving a data stream comprising at least two distinct sets of encoded data, at least one set of which is relative to transient/stochastic components of a signal. Based at least in part on the distinct sets of encoded data, the signal processor decodes and reconstructs a corresponding rendition of signal for each set of the encoded data. The distinct sets of renditions of signal are then combined into a single rendition of reconstructed signal.
