Transport stream multiplexing method, program receiver, server and system

Abstract

The invention provides a transport stream multiplexing method, which includes the following steps: original program streams are acquired by a program receiver, PSI / SI (program specific information / service information) of the original program streams is analyzed; the PSI / SI is transmitted to an EPG (electronic program guide) server; PSI / SI information streams are generated by the EPG server according to the PSI / SI and preset program information; the original program streams are output to a corresponding transparent transmission port of an IPQAM (internet protocol quadrate amplitude modulation) corresponding to frequency point by the program receiver; the PSI / SI streams are output to the corresponding transparent transmission port of the IPQAM by the EPG server; and the original program streams and the PSI / SI are multiplexed and then displayed at the preset frequency point by the IPQAM. The transport stream multiplexing method is capable of multiplexing the PSI / SI to the single TS (transport stream) without using any multiplexer. The invention also discloses the program receiver, the EPG server and a transport stream multiplexing system.

Description

technical field [0001] The invention relates to the field of digital television, in particular to a transport stream multiplexing method, program receiving device, server and system. Background technique [0002] PSI / SI (Program Specific Information / Service Information, program specific information and service information) information is the basic information of DVB (Digital Video Broadcasting, digital television broadcasting), and the existing digital television broadcasting network transmits PSI / SI information in the network , used to describe information such as networks, transport streams, services, and program events. [0003] The PSI in the digital TV broadcasting operation network generally includes the following information: PAT (Program Association Table, program association table), CAT (Conditional Access Table, conditional access table), TSDT (Transport Stream Description Table, transport stream description table), NIT ( Network Information Table, network informa...

AI Technical Summary

Problems solved by technology

[0005] The above method of multiplexing PSI / SI information and program source information through a multiplexer and then broadcasting to each set-top box is suitable for broadcasting and television operators to broadcast digital TV programs to a large number of users, but for other cases, for example, in the laboratory for Debugging software needs to test and analyze PSI / SI information. If multiplexers are used to implement, the cost is very high, and many functions of the multiplexer cannot be used, resulting in waste of resources.
