摘要： Embodiments for reducing redundancy in video coding are disclosed. In accordance with at least one embodiment, video content is represented as a tree structure in which the nodes of the tree structure are associated with attributes of the video content. An encoder analyzes the nodes to determine whether there is redundancy associated with a last node of a divided node. In another embodiment, bidirectional prediction video coding techniques are applied to the video content. The encoder analyzes two lists of reference frames to determine whether a third mode of bidirectional prediction is redundant to a second mode of bidirectional prediction. The efficiency of video coding is improved by refraining from sending data symbols to the decoder in the event that the video coding techniques contain redundancy.

摘要： Disclosed herein are representative embodiments for performing entropy coding or decoding using a counter-based scheme. In one exemplary embodiment disclosed herein, a first codeword is received from compressed digital media data. The first codeword is decoded into a first digital media data value by referencing a codeword table that associates the first codeword with the first digital media data value and a second codeword with a second digital media data value. A counter for counting occurrences of the first digital media data value is incremented. The value of the first counter is compared with the value of a second counter that counts occurrences of a second digital media data value. If the value of the first counter and the value of the second counter are equal (or greater than or equal), the codeword table is updated to swap codewords between the first and second digital media values.

摘要： Techniques for implementing video encoding enhancements may increase video encoding efficiency. One of the techniques may involve the use of an exception value and a maximum index value in inter-prediction coding lookup table to enhance the combined coding of an inter-prediction direction and a reference frame index for a coding unit. Another of the techniques may include adaptively ordering the encoding of a split flag value and a skip flag value for a coding unit. An additional technique may include providing a uniform approach to adaptively combined code the coded block flag (CBF) values for transform or coding units of images that are used with the Residue Quad-tree (RQT) information to represent residue information.

摘要： Techniques for coding and deriving (e.g., determining) one or more coded-block-flags associated with video content are described herein. A coded-block-flag of a last node may be determined when coded-block-flags of preceding nodes are determined to be a particular value and when a predetermined condition is satisfied. In some instances, the predetermined condition may be satisfied when log2(size of current transform unit) is less than log2(size of maximum transform unit) or log2(size of current coding unit) is less than or equal to log2(size of maximum transform unit)+1. The preceding nodes may be nodes that precede the last node on a particular level in a residual tree.

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.

摘要： Innovations in unified intra block copy (“BC”) and inter prediction modes are presented. In some example implementations, bitstream syntax, semantics of syntax elements and many coding/decoding processes for inter prediction mode are reused or slightly modified to enable intra BC prediction for blocks of a frame. For example, to provide intra BC prediction for a current block of a current picture, a motion compensation process applies a motion vector that indicates a displacement within the current picture, with the current picture being used as a reference picture for the motion compensation process. With this unification of syntax, semantics and coding/decoding processes, various coding/decoding tools designed for inter prediction mode, such as advanced motion vector prediction, merge mode and skip mode, can also be applied when intra BC prediction is used, which simplifies implementation of intra BC prediction.
