For interlaced half-frame or interlaced B- B- frame, use 4MV encoding. 编码器/解码器使用"自参考"B-帧。 The encoder / decoder uses a "self-referential" B- frames. 编码器发送二进制信息,表示对隔行扫描B-半帧的一个或多个宏块的预测模式是正向还是非正向的。 The encoder transmits binary ...

An aspect central to each of the MPEG standards are the video encoding and decoding algorithms that make digital video applications practical. The MPEG standards are discussed in Sections 6.4 and 6.5. Video compression not only reduces the storage requirements or transmission bandwidth of digital ...
When paired, encoding and decoding enable efficient live video delivery under the constraints of your network. It's all well and good until you realize you don't really want every viewer to receive that 1080p60 video. Viewers watching the stream over limited network connections and on small sc...
There are disclosed various methods, apparatuses and computer program products for video encoding and decoding. In some embodiments for encoding a block of samples is obtained for motion prediction (). At least one translational base motion vector component for the block of samples is calculated by...

Video encoding and decoding methods and apparatuses are provided which are effective for error correction and error concealment in an error-prone environment. The video encoding method includes determining an encoding operation to encode raw video among a frame encoding operation, a top/bottom field en...
A video frame arithmetical context adaptive encoding and decoding scheme is presented which is based on the finding, that, for sake of a better definition of neighborhood between blocks of picture samples, i.e. the neighboring block which the syntax element to be coded or decoded relates to and...

Disclosed are a method and apparatus for improving the accuracy of intra-prediction in order to improve encoding and decoding efficiency. The video decoding method may improve the prediction efficiency for the current pixel to be predicted by referring to the degree of variation in surrounding pixels...
