Claim:
1. A method, comprising: receiving a transport stream comprising a head stream and a tail stream, the head stream and the tail stream each comprising a compressed video sequence from a separate video source; processing an adaptation field of a transport packet corresponding to the head stream, the adaptation field comprising a splice out-point that corresponds to a splice point, the splice point provided based on a presentation time stamp value, the splice out-point signaled by a descriptor in a program map table, the transport packet further comprising assistive information comprising one or more compressed picture buffer properties and one or more decoded picture buffer properties; and concatenating the head stream and the tail stream based on the compressed picture buffer properties and the decoded picture buffer properties, wherein the compressed picture buffer properties comprise at least a coding level, wherein the compressed picture buffer properties further comprise one or more of a value corresponding to a decoded time stamp value minus a system time clock value, a buffer level, and an intended compressed picture buffer upper bound level and compressed picture buffer lower bound level, wherein the decoded picture buffer properties comprise a first flag corresponding to a presentation time stamp value corresponding to a last picture in the decoded picture buffer, wherein the decoded picture buffer properties further comprise a second flag, the second flag signaling that all pictures yet to be output residing in the decoded picture buffer have successive picture output times, wherein the second flag further signals a first output time of the pictures yet to be output, and wherein the first output time corresponds to a first frame interval after the splice out-point, the first frame interval enabling pictures from the headstream to be outputted in the decoded picture buffer while pictures from the tail stream are being decoded and stored in the decoded picture buffer.
