Abstract
Systems and methods are provided for seamless assembly of video/audio segments. To achieve such seamless assembly during streaming/online progressive download of media, a second segment is downloaded to a client during the presentation of a first segment. The first segment is then attached to the beginning of the second segment, where no jitter or gap results with the transition point either in the video or audio portion of the segments. Hence, the merged segments are presented as a seamless assembly of video/audio segments, where the user is “unaware” that the merged segments are the result of two separate or different segments. To effectuate such gapless assembly of segments, a gapless media file is created for encoding the video and audio segments using a gapless audio encoding scheme, such as Ogg Vorbis, where synchronized, gapless audio tags are interleaved in the video segments.
