Seamless trick-mode with decreased latency for live transcode streaming

A device for performing seamless trick-mode operations with decreased latency for transcode streaming, the device comprising:

• an input buffer to receive, from a source, and record a stream of video data while generating intended segment boundary information;
• a single transcoder to transcode the stream of video data and to generate output video data in an output buffer;
• and
• a controller to:
• generate segmentation index information in an output index buffer;
• and
• respond to a skip-backwards request from a client device by:
• retrieving transcoded video data from the output buffer, based on segment request information received from the client device if video data corresponding the segment request information associated with the skip-backwards request are available from the output buffer;
• and
• otherwise, retrieving recorded video data from a first storage and causing the single transcoder to transcode the retrieved recorded video data,
• wherein the stream of video data comprises input segmentation boundary markers, and the single transcoder is to generate output video data by aligning the output video data with the input segmentation boundary markers of the stream of video data received from the source by inserting random access pictures in the output video data at positions corresponding to the input segmentation boundary markers.

A system for performing seamless trick-mode operations with decreased latency for transcode streaming, the system comprising:

• memory to store one or more program modules;
• one or more processors coupled to the memory, the one or more processors to execute the one or more program modules to:
• receive, from a source, a stream of video data;
• record the stream of video data in an input storage;
• generate segmentation boundary information in the input storage;
• transcode, by using a single transcoder, the stream of video data and generate output video data in an output buffer;
• and
• respond to a skip-backwards request from a client device by:
• retrieving transcoded video data from the output buffer, based on segment request information received from the client device if video data corresponding the segment request information associated with the skip-backwards request are available from the output buffer;
• and
• otherwise, retrieving and transcoding recorded video data from a first storage,
• wherein the stream of video data comprises input segmentation boundary markers, and generating output video data comprises aligning the output video data with the input segmentation boundary markers of the stream of video data received from the source by inserting random access pictures at positions corresponding to the input segmentation boundary markers.
