Abstract
In accordance with certain embodiments consistent with the present invention, a method providing alternate digital audio and video content in a segment of content containing compressed primary audio and encoded primary video involves inserting blank audio in an alternate audio track between segments of alternate audio; inserting black video in an alternate video track between segments of alternate video; synchronizing the alternate audio track to a master timeline; synchronizing the alternate video track to the master timeline; compressing the alternate audio track; compressing the alternate video track; trimming the blank audio from the compressed alternate audio track; trimming the black video from the compressed alternate video track; synchronizing the trimmed compressed alternate audio to locate the trimmed compressed alternate audio temporally with the primary compressed audio; synchronizing the trimmed compressed alternate video to locate the trimmed compressed alternate video temporally with the primary encoded video; and multiplexing the trimmed compressed alternate audio and the trimmed compressed alternate video with the primary compressed audio and the primary encoded video. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
