ABSTRACT:
Method and apparatus are provided for segmenting a multiple program multimedia digital data stream for transmission over a distribution communications network. Each program multimedia digital data stream includes sequential transport system (TS) packets with program clock references (PCRs) at a set time interval and a program identification (PID) associated with the PCRs. The multiple program multimedia digital data stream is received. The TS packets are decoded to identify the program clock references (PCRs). A selected number N of TS packets are identified. The multimedia digital data stream into frames responsive to both the identified number N of TS packets and the identified PCRs. A program identification (PID) associated with one of the PCRs is selected for timing the transmission of segmented multiple program multimedia digital data stream. A time interval following an identified PCR associated with the selected program identification PID is identified and compared with the set time interval between the program clock references (PCRs). Responsive to the identified time interval being greater than the set time interval, a new program identification (PID) is selected for timing the transmission of segmented multiple program multimedia digital data stream.
