Abstract
Systems, methods, and devices enabling scalability to be incorporated into a media presentation such that the media presentation at a client end may be continuous or at least substantially continuous in the presence of missing segment files. In an embodiment, the loss of one or more segment file may not require a media presentation interval associated with the missing segment file to be skipped at the client end. Systems, methods, and devices enable scalability in live streaming and/or on-demand presentations.
Claims41
A method for presenting video on a receiver device including a client, the method comprising:
- by the client of the receiver device:
- receiving a proper subset of a set of temporally-overlapping scalable segments in at least two video transport files, wherein each of the at least two video transport files includes interleaved scalable segments derived from at least two video segments of a video stream, the proper subset including an amount of data sufficient to enable the client to render the at least two video segments at or above a quality threshold using only the proper subset, wherein the set of temporally-overlapping scalable segments are derived from the at least two video segments such that recombining all the set of temporally-overlapping scalable segments will result in playback of the at least two video segments at an original resolution of the video stream, and wherein each of the at least two video transport files is received at different times;
- determining that at least one of the set of temporally-overlapping scalable segments is lost;
- and
- in response to determining that at least one of the set of temporally-overlapping scalable segments is lost, using the received proper subset of temporally-overlapping scalable segments to render the at least two video segments at or above the quality threshold.
