CODEC TECHNIQUES FOR FAST SWITCHING

摘要

A video streaming method for transitioning between multiple sequences of coded video data may include receiving and decoding transmission units from a first sequence of coded video data. In response to a request to transition to a second sequence of coded video data, the method may determine whether a time to transition to the second sequence of coded video data can be reduced by transitioning to the second sequence of coded video data via an intermediate sequence of coded video data. If the time can be reduced, the method may include receiving at least one transmission unit from an intermediate sequence of coded video data that corresponds to the request to transition, decoding the transmission unit from the intermediate sequence, and transitioning from the first sequence to the second sequence via the decoded transmission unit from the intermediate sequence.

1. A video streaming method, comprising:
receiving transmission units from a first sequence of coded video data; decoding the transmission units from the first sequence; in response to a request to transition to a second sequence of coded video data, receiving transmission units from the second sequence of coded video data; and decoding the transmission units from the second sequence, wherein decoding the transmission units from the second sequence includes:
buffering a selected transmission unit from the second sequence that includes a frame corresponding to the request to transition,decoding reference frames of the selected transmission unit up to the frame that corresponds to the request to transition, and
