Abstract

The DTV program multiplexer in system level needs to combine many programs and some message into multi-program TS for transporting in the channel. Because DTV program contains audio and video signal, and the fluctuation of code rate is very large, data packet is easy to lose in the process of combining them into a data stream at a steady rate. Therefore, the research on dispatch algorithm about DTV multiplexer is of vital importance. This paper puts forward a two-level joint dispatching method with monopolizing and sharing buffers, which gets packets from monopolizing buffers respectively, and forms a buffer array supporting priority in sharing buffer, and then outputs at steady rate. Through verify this method has less data loss rate at equivalent serve intension.
