摘要：
Design of transport stream (TS) remultiplexer with CPLD is described in this paper. PID mapping and PCR correction are two important functions of TS remultiplexer. For saving resource, simple RAM architecture is substituted by the combination of content-addressable-memory (CAM) and RAM, when forming a high-speed PID information table. An uncomplex algorithm of PCR correction is given in this paper. Experiment result show that the jitter can be reduced to less than 74ns.
