Patent ID: 8300690

Claim:
A method of encoding a video sequence, comprising: providing a first indication in an encoded bitstream by a video encoder, the first indication indicating whether or not all coded pictures at and subsequent to an intra-coded picture in display order can be correctly decoded when a decoding process is started from the intra-coded picture; and encoding a first picture into the encoded bitstream by the video encoder, using motion-compensated prediction with reference to one or more previously coded reference pictures, the first picture having a display order prior to the intra-coded picture and an encoding order succeeding the intra-coded picture; providing a second indication in the encoded bitstream by the video encoder corresponding to the first picture, which indication indicates whether or not the first coded picture can be correctly decoded when the decoding process is started from the intra-coded picture; performing motion compensated prediction by the video encoder for at least part of a second picture with reference to the first coded picture.
