Abstract: Systems and methods are disclosed herein for selective audio segment compression for accelerated playback of media assets. A playback speed of the video segment of a media asset is calculated based on the duration of the video segment and a received playback time period. A priority weight for each of the various audio segments is then determined. The audio segments with the lowest priority weight are removed from the group of various audio segments. The system then determines whether the duration of the remaining audio segments exceeds the received playback time period. If so, the system modifies the remaining audio segments by removing another audio segment with the lowest priority weight from the remaining audio segments. The system then rechecks whether the received playback time period is exceeded. If not, the system generates for playback the video segment based on the video playback speed and the remaining audio segments.

Abstract: Systems and methods are disclosed herein for selective audio segment compression for accelerated playback of media assets by service providers. A playback speed of the video segment of a media asset is calculated based on the duration of the video segment and a received playback time period. The system receives audio segments and corresponding priority weights. The audio segments with the lowest priority weight are removed from the group of various audio segments. The system then determines whether the duration of the remaining audio segments exceeds the received playback time period. If so, the system modifies the remaining audio segments by removing another audio segment with the lowest priority weight from the remaining audio segments. The system then rechecks whether the received playback time period is exceeded. If not, the system generates for playback the video segment based on the video playback speed and the remaining audio segments.

Abstract: Systems and methods are disclosed herein for varied audio segment compression for accelerated playback of media assets. A priority weight for each of the various audio segments is then determined. Each audio segment for use during accelerated playback is based on the priority weight of that audio segment, the received playback time period, and a duration of that audio segment. A sum of the modified time for each audio segment equals the received playback time period. An accelerated playback speed for each audio segment is determined based on the modified time for that audio segment and the duration of that audio segment. The technique generates for playback the video segment based on a determined video playback speed and the audio segments based on the accelerated playback speed for each audio segment.
