Abstract
Disclosed are methods and apparatuses for stitching a first and second audiovisual segment together. By way of example, each audiovisual segment has a multiplicity of audio frames including a first audio frame, a second audio frame that sequentially follows the first audio frame and a last audio frame. The audiovisual segment further includes a multiplicity of video frames having a first video frame and a last video frame. The method includes the step of aligning an initial audio frame in the first audiovisual segment with the first video frame in the first audiovisual segment. The first audio frame from the first audiovisual segment is designated as the initial audio frame when a tab error associated with the first audio frame from the first audiovisual segment is less than about half a frame. On the other hand, the second audio frame from the first audiovisual segment is designated as the initial audio frame when a tab error associated with the first audio frame from the first audiovisual segment is greater than half a frame. Stitching the first and second audiovisual segments together.
