Abstract:
1. A transport stream processing apparatus, comprising: a demodulator, configured for demodulating an input signal to generate a first transport stream; a transport stream storage, configured for storing a second transport stream; a multiplexer, having an output port, a first input port configured for receiving the first transport stream, and a second input port configured for receiving the second transport stream, wherein the multiplexer selectively couples the first input port or the second input port to the output port; and a conditional access system interface, coupled to the output port of the multiplexer and configured for coupling a conditional access card, wherein the conditional access system interface transmits a transport stream outputted from the output port of the multiplexer to the conditional access card for signal processing when the conditional access card is coupled to the conditional access system interface; wherein the multiplexer couples the first input port to the output port when the conditional access card is coupled to the conditional access system interface and complies with a first conditional access specification, and couples the second input port to the output port when the conditional access card is coupled to the conditional access system interface and complies with a second conditional access specification different from the first conditional access specification.
