Abstract
A transport stream processing apparatus includes a demodulation module, a transport stream storage module, a multiplexer, and a conditional access system interface. The demodulation module is for demodulating an input signal to generate a first transport stream. The transport stream storage module is for storing a second transport stream. The multiplexer has an output port, a first input port for receiving the first transport stream, and a second input port for receiving the second transport stream. The multiplexer selectively couples the first input port or the second input port to the output port. The conditional access system interface is coupled to the output port of the multiplexer for coupling a conditional access module. The conditional access system interface transmits a transport stream outputted from the output port of the multiplexer to the conditional access module for signal processing when the conditional access module is coupled to the conditional access system interface.
