A system and method for coding video data in pattern mode for display stream compression (DSC) is disclosed. In one aspect, the method includes determining that a first pattern in a current block of video data is not in a pattern database comprising a plurality of patterns, and adding the first pattern to the pattern database. The first pattern may be associated with a first index identifying a location of the first pattern in the pattern database. The method further includes coding the current block in pattern mode at least in part via signaling (i) the first pattern determined not to be in the pattern database and (ii) the first index identifying the location of the first pattern in the first database.

A computer-implemented method for compressing a data set, the method comprising receiving a first data block of the data set, selecting automatically by a compression management module a compression module from a plurality of compression modules to apply to the first data block based on projected compression efficacy or resource utilization, and compressing the first data block with the selected compression module to generate a first compressed data block.

There are provided a method and apparatus for illumination and color compensation for multi-view video coding. A video encoder includes an encoder for encoding a picture by enabling color compensation of at least one color component in a prediction of the picture based upon a correlation factor relating to color data between the picture and another picture. The picture and the other picture have different view points and both corresponding to multi-view content for a same or similar scene.

A method of encoding video including: writing a plurality of predetermined buffer descriptions into a sequence parameter set of a coded video bitstream; writing a plurality of updating parameters into a slice header of the coded video bitstream for selecting and modifying one buffer description out of the plurality of buffer descriptions; and encoding a slice into the coded video bitstream using the slice header and the modified buffer description.

A method includes intra-refresh encoding each picture of a first set of pictures such that a position of a refresh region for the picture is spatially shifted relative to the position of the refresh region for a previous picture of the first set responsive to determining global motion associated with the first does not exceed a specified threshold. The method further includes intra-refresh encoding each picture of a second set of pictures such that a position of a refresh region for each picture of the second set is fixed to be immediately adjacent to a picture edge that is in a direction of global motion associated with the second set responsive to determining the global motion associated with the second set exceeds the specified threshold.

Systems and methods are provided herein relating to adaptive video streaming. Time-to-offset mapping associated with a set of video blocks can be broken up into chunks. A client can download a first set of seek index chunks and use the first set of seek index chunks to select a stream. Seek index chunks within remaining sets of seek index chunks can be ranked for relevance based on client capabilities. A subset of remaining sets of seeks index chunks can be downloaded based on the rankings and client capabilities during streaming. Chunked time-to-offset mapping can facilitate faster startup when playing streamed video.
