SPLICING COMPRESSED LOCAL VIDEO SEGMENTS INTO FIXED TIME SLOTS IN NETWORK FEED

摘要

PROBLEM TO BE SOLVED: To provide techniques to splice compressed local video segments into fixed time slots in a network feed for generation of digital video signals.

SOLUTION: Provided is a method for seamlessly splicing a local commercial segment into an existing network time slot, without decoder buffer overflow or underflow. The vbv_delay of the commercial segment is controlled (e.g., for a minimum delay or a maximum delay). Pictures from the commercial segment are output for at least a portion of the associated network time slot duration. A determination is made regarding the number of pictures remaining in a stored portion of an incoming network feed or the commercial segment and an output rate is adjusted as required.
