A motion information storing method and a TMVP deriving method using the motion information storing method are provided. The motion information storing method includes a step of determining a representative block out of blocks of a motion data storage unit in a co-located picture with a current picture and a step of storing motion information of the representative block as motion information of the motion data storage unit, wherein the motion information of the representative block is used as motion information of the blocks included in the motion data storage unit.

A method is provided of decoding video data using a merge mode. A merge list is constructed using available spatial and temporal merge candidates. A merge candidate on the merge list corresponding to a merge index is determined as motion information of a current prediction unit. A predicted block of the current prediction unit is generated using the motion information. A transformed block is generated by inverse-quantizing a block of quantized coefficients using a quantization parameter. A residual block is generated by inverse-transforming the transformed block. A reconstructed block is generated using the predicted block and the residual block.

Coding techniques for input video may include assigning picture identifiers to input frames in either long-form or short-form formats. If a network error has occurred that results in loss of previously-coded video data, a new input frame may be assigned a picture identifier that is coded in a long-form coding format. If no network error has occurred, the input frame may be assigned a picture identifier that is coded in a short-form coding format. Long-form coding may mitigate against loss of synchronization between an encoder and a decoder by picture identifiers.

A video decoding method involving intra prediction includes: parsing a most probable mode (MPM) flag of a block while parsing symbols of the block of an encoded video from a received bitstream; determining whether a predetermined number of a plurality of candidate intra prediction modes are used to predict an intra prediction mode of the block based on the MPM flag; when it is determined that the plurality of candidate intra prediction modes are used based on the MPM flag, determining the plurality of candidate intra prediction modes based on intra prediction modes of a left block and an upper block that are adjacent to the block while restoring the intra prediction mode of the block by using the parsed symbols.

Hybrid video decoder supporting intermediate view synthesis of an intermediate view video from a first- and a second-view video which are predictively coded into a multi-view data signal with frames of the second-view video being spatially subdivided into sub-regions and the multi-view data signal having a prediction mode is provided, having: an extractor configured to respectively extract, from the multi-view data signal, for sub-regions of the frames of the second-view video, a disparity vector and a prediction residual; a predictive reconstructor configured to reconstruct the sub-regions of the frames of the second-view video, by generating a prediction from a reconstructed version of a portion of frames of the first-view video using the disparity vectors and a prediction residual for the respective sub-regions; and an intermediate view synthesizer configured to reconstruct first portions of the intermediate view video.
摘要:
A system may receive an input stream for a coding operation by a coding device. The system may determine a processing device to assist the coding device with the coding operation. The processing device may generate an indicator containing coding information or other coding assistance by processing the input stream. The processing device may send the indicator to the coding device. In some cases, the indicator may be embedded in the metadata of the stream by the processing device. The indicator may be extracted by the coding device. After reception of the indicator, the coding device may execute the coding task while using the information in the indicator to assist.

A method and system for the UE and RNC to reduce transmission latency and potentially prevent loss of PDUs upon a MAC-hs layer reset. The RNC generates a radio resource control (RRC) message with a MAC-hs reset indication. The MAC reset indication requires the UE to flush buffers for configured HARQ processes, disassemble MAC protocol data units (PDUs) in the reordering buffers, deliver MAC-d PDUs to a MAC-d layer, and configure the MAC-hs to receive new data.
