PRESENTATION TIMELINE SYNCHRONIZATION ACROSS AUDIO-VIDEO (AV) STREAMS

摘要

A system for presentation timeline synchronization across audio-video (AV) streams associated with a common event may include memory and a processor. The processor may be configured to receive metadata items from a user device during a live event, the metadata items corresponding to points-in-time marked by the user while being presented with an audio-video (AV) stream associated with the live event. The metadata items may include timing indicators that are indicative of the marked points-in-time relative to the start of the live event. The processor may be configured to provide to the user device with other AV streams associated with the live event that were available at one of the points-in-time marked by the user. The processor may be configured to provide the other AV streams to the user device beginning with a frame that corresponds to the one of the points-in-time marked by the user.

主权项

1. A computer program product comprising instructions stored in a tangible computer-readable storage medium, the instructions comprising:
instructions for receiving a metadata item that comprises an identifier of an event and a timing indicator; instructions for identifying, based at least on the identifier of the event, a plurality of video streams associated with the event; instructions for correlating the timing indicator to one of the plurality of video streams associated with the event; instructions for matching the timing indicator to a frame of the one of the plurality of video streams; and instructions for appending a timestamp associated with the frame to the metadata item and storing the metadata item.
