Abstract
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 manipulated (e.g., for a minimum delay or a maximum delay). The 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 the incoming network feed or the commercial segment and the output rate is adjusted as required. The vbv_delay of the stored network feed or the vbv_delay of the local commercial segment is adjusted to match the vbv_delay of the incoming network feed.
