SEAMLESS TRICK-MODE WITH DECREASED LATENCY FOR LIVE TRANSCODE STREAMING

机译:具有降低的延迟的无缝特技模式,可进行实时代码转换

摘要

A method for performing trick-mode operations with decreased latency for transcode streaming includes receiving and recording a stream of video data. A single transcoder may transcode the stream of video data and generate output video data in an output buffer following. Segmentation index information may be generated that refers to the output data in the output buffer. Skip-backwards, skip-ahead, and resume requests received from a client device are responded by retrieving transcoded video data from the output buffer or retrieving and transcoding video data from an input storage. A method for performing skip-ahead trick-mode operation with decreased latency may use two transcoders such as two threads of the single transcoder to transcode temporally current content and forward content. The forward content may be associated with a forward time offset with respect to the temporally current content. The transcoded forward content is provided in response to skip-ahead trick mode request.
