Error resilient management of picture order count in predictive coding systems
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.
