Method and apparatus for variable accuracy inter-picture timing specification for digital video encoding

摘要

The present invention concerns methods and bitstreams for variable accuracy inter-picture timing specification for digital video encoding. One method comprises receiving a first and a second video picture, the first video picture comprising a B 5 frame and decoding the second video picture based on the first video picture. A further method comprises encoding a first picture, a second picture, and an order value for the second video picture, the order value representative of a position of the second picture with reference to the first picture in a sequence of video pictures, where the order value is for decoding the second video picture. A bitstream is provided which comprises a 10 first and a second video picture, and an order value for specifying a positional relationship between the second video picture and said first video picture. -- T
