INSERTION OF RECORDED SECONDARY DIGITAL VIDEO CONTENT DURING PLAYBACK OF PRIMARY DIGITAL VIDEO CONTENT

摘要

A method of operating a digital video service set top box system is provided. The set top box system accommodates playback of locally stored recorded secondary digital video content. The method begins by initiating playback of a primary digital video program. Insertion points associated with the primary digital video program are detected; these insertion points indicate frame-accurate transition points in the primary digital video program. During playback of the primary digital video program, the recorded secondary digital video program is inserted at any appropriate insertion point in a frame-accurate manner. The termination of the secondary digital video program is likewise marked and triggers a return to the primary digital video program, at the original insertion point or any other desired insertion point which may exist in the primary digital video program.
