Step S304, DVB is packaged into the IP bag with original program stream and outputs to switch, this original program stream that is packaged into the IP bag is outputed to the corresponding transparent transmission port number of the corresponding IPQAM of predetermined frequency through switch.
Concrete, DVB is packaged into the IP bag afterwards outputs to switch through its Ethernet interface Ethernet interface with original program stream, outputs to IPQAM again through switch.In general, IPQAM has 8 or 16 transparent transmission ports number, and each transparent transmission port correspondence one is broadcast frequency.Such as; Certain preset frequency is that the IP address of the corresponding IPQAM of 722MHZ is 10.10.99.123; Transparent transmission port number is 2; Except designated switch IP address, also need IP address and the transparent transmission port number of assigned ip QAM, i.e. 10.10.99.123:2 when then DVB outputs to switch with original program stream.
Step S305, the EPG server is packaged into IP bag with the PSI/SI information flow and outputs to switch, this PSI/SI information flow that is packaged into the IP bag is outputed to the corresponding transparent transmission port number of IPQAM among the step S304 through switch.
Step S306, switch output to original program stream and PSI/SI information flow the corresponding transparent transmission port number of IPQAM among the step S304.
Step S307, IPQAM carries out original program stream and PSI/SI information flow multiplexing, and is modulated into after the radiofrequency signal at the corresponding frequency of this transparent transmission port number and broadcasts.
Step S308, the predetermined frequency among the digital TV terminal given step S304 is searched for, and searches the program stream that comprises EPG information and program source information.
Implement the foregoing description; Information through obtaining original program stream generates the PSI/SI information flow; And just original program stream and the PSI/SI information flow that the generates same transparent transmission port that outputs to same IPQAM number carry out multiplexing with broadcast; Can not need use multiplexer, the PSI/SI information multiplexing in single TS stream, is reduced cost.
