Abstract: 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.

Abstract translation: 用于在多个编码视频数据序列之间转换的视频流方法可以包括从第一编码视频数据序列接收和解码传输单元。 响应于转换到第二编码视频数据序列的请求，该方法可以通过经由中间序列转换到第二编码视频数据序列来确定是否可以减少转换到第二编码视频数据序列的时间 的编码视频数据。 如果可以减少时间，则该方法可以包括从与转换请求对应的编码视频数据的中间序列接收至少一个传输单元，从中间序列解码传输单元，以及从第一序列转换到 通过来自中间序列的解码传输单元的第二序列。
