Comprehensive information broadcasting method based on dtmb transmission platform

Abstract

The invention discloses a general information broadcasting method based on the DTMB transmission platform and relates to the technical field of broadcasting. The general information broadcasting method based on the DTMB transmission platform comprises the steps that (1) a server, a public broadcast module, a telephone live broadcasting module, an administrator client module, a GPRS module, a network switch, an IP webmaster and a TS stream multiplexer are arranged at the front end of a broadcasting device, (2) control data and audio data from the public broadcast module, the telephone live broadcasting module, the GPRS module and the administrator client module are packaged by the TS stream multiplexer to form TS stream data which accord with DTMB transmission, (3) the TS stream is transmitted to a broadcast terminal through a DTMB ground digital television front-end system and a DTMB ground digital television transmission system, and (4) signal searching and checking are carried out on received voice packet information by the broadcast terminal, and the fact whether broadcasting of general information is stopped or waits to be broadcasted is determined. The general information broadcasting method based on the DTMB transmission platform has the advantages that the existing DTMB transmission platform is used for general broadcasting, a broadcasting network does not need to be additionally established, cost is low, and popularization is facilitated.

Description

technical field [0001] The invention belongs to a broadcasting system, in particular to a comprehensive information broadcasting method based on a DTMB transmission platform. Background technique [0002] Existing broadcast transmission systems include: 1. Based on audio constant pressure wired broadcasting system; 2. Based on wireless frequency modulation and CATV cable TV common cable transmission FM plus SCA / RDS subcarrier coding combined with remote telephone addressable broadcasting system; 3. Weather and disaster warning broadcasting system based on GPRS / GSM. The above three forms of broadcasting systems mainly use analog signal transmission, and the technology is relatively backward. Its application involves huge network construction and tedious daily system maintenance. At present, because the country has no staffing of broadcasting stations, the daily management of broadcasting stations is in the The embarrassing situation of unmanned maintenance severely restricts...

Problems solved by technology

The above three forms of broadcasting systems mainly use analog signal transmission, and the technology is relatively backward. Its application involves huge network construction and tedious daily system maintenance. At present, because the country has no staffing of broadcasting stations, the daily management of broadcasting stations is in the The embarrassing situation of unmanned maintenance severely restricts the normal operation of the broadcasting system, greatly reducing the service life of the broadcasting system

[0003] In addition, the traditional broadcast transmission system cannot effectively integrate daily public broadcasting, disaster warning broadcasting and emergency broadcasting of government departments at all levels, resulting in redundant construction with little effect; lack of public security department, fire department, water conservancy The effective integration of information released by government departments at all levels, such as the Seismic Bureau, the Bureau of Culture and Broadcasting, cannot convey information quickly and accurately; there is a lack of recording of the broadcast content of the broadcasting system and monitoring of the system's operating status
