Abstract

This paper presents the design and implementation of an MPEG-2 transport stream (TS) remultiplexer, which is one of the most important pieces of equipment in a digital television broadcasting system. To achieve high performance as well as save hardware resources, the architecture of CAM+RAM is proposed to substitute simple RAM where a PID information table is generated. Compared to other methods, the two-step PCR correction approach can simplify the system significantly. Three data insertion modes are discussed in this paper. Among of them, the host-downloading architecture supports the system to work in a standalone mode when the contents of data are repeated with a fixed time interval or change not very fast
