    摘要: Innovations in the areas of hash table construction and availability checking reduce computational complexity of hash-based block matching. For example, some of the innovations speed up the process of constructing a hash table or reduce the size of a hash table. This can speed up and reduce memory usage for hash-based block matching within a picture (for block vector estimation) or between different pictures (for motion estimation). Other innovations relate to availability checking during block vector estimation that uses a hash table.

    摘要: Systems and methods are described for joint spatio-temporal prediction (JSTP) during video coding. A given block of pixels is simultaneously predicted via inter frame prediction and intra frame prediction. The joint spatio-temporal prediction provides a new JSTP coding mode besides inter and intra modes in coding schemata such as the H.264/AVC video coding standard. In one implementation, subband decomposition obtains a high-pass component of inter frame prediction of a block and a low-pass component of intra frame prediction of the same block. The high-pass component of the inter prediction and the low-pass component of the intra prediction are combined to produce the joint spatio-temporal prediction. In one implementation, a difference between the original block and the JSTP prediction is coded in a bitstream to represent the block.

    摘要: A method for compressing a high dynamic range (HDR) texture. A first block of texels of the HDR texture in a red-green-blue (RGB) space may be transformed to a second block of texels in a luminance-chrominance space. The first block may have red values, green values and blue values. The second block may have luminance values and chrominance values. The chrominance values may be based on a sum of the red values, a sum of the green values and a sum of the blue values. The luminance values and the chrominance values may be converted to an 8-bit integer format. The luminance values may be modified to restore a local linearity property to the second block. The second block may be compressed.

    摘要: Architecture that improves error robustness in video coding and decoding. In particular, this can apply to motion vector prediction (MVP) such as a temporal MVP (TMVP). Flags can be used to indicate the use or non-use of a feature, such as to indicate whether the current slice uses or does not use TMVP, and to indicate in the slice header whether list prediction is allowed or not allowed. A flag can be signaled in sequence parameter set (SPS) or picture parameter set (PPS) as a way to enable an entire sequence to use or not use TMVP. TVMP can also be used to copy all the reference motion information to the current block. To address possible error problems, the full index of the TMVP can be recorded, and temporal information decoding refresh (TIDR) can be inserted into slices periodically.
