System for realizing multimedia classified advertising on digital television network

Abstract

The invention discloses a system for realizing multimedia classified advertising on a digital television network. The system comprises the following working procedures: an advertising emission system groups the multimedia advertising through an advertising arranging system, stores after the control information is added and extracts the grouped advertising content and the control information from the database through starting a TS generation broadcast control system into TS stream to emit; the advertising data stream and audio / video stream are multiplexed through a multiplexer and a DVB modulator and modulated as well as emitted to a digital television transmission network; a reception terminal firstly locks a frequency point and then broadcasts the audio-video programs; the terminal continues to search and analyze relevant data and compares the ID number in the control information with the ID of the native machine; and if the IDs are matched with each other, the analyzed advertising content is displayed on the specified position of the screen according to the description of the control information. The system adopts the existing digital television transmission channel to transmit the advertising content grouping to the terminal. The system is suitable for wide promotion due to simple structure, low cost and convenient use.

Description

technical field [0001] The invention relates to a classified broadcast control system for advertisements, in particular to a system for realizing classified broadcast control of multimedia advertisements by using digital cable / terrestrial / satellite transmission channels. Background technique [0002] Digital TV has brought great changes in broadcasting content, program form, service mode, receiving mode, and profit model to the broadcasting industry, and has also opened up a rich imagination space for future development. With the continuous deepening of China's digital TV conversion and translation, the continuous promotion of terrestrial wireless digital TV CTTB, and the launch of the China Star No. 9 live broadcast satellite, digital TV network transmission has become the carrier of new media. [0003] At present, the mainstream digital TV receiving terminals in the market are mainly concentrated in the fields of households, buses, vehicles and buildings. The basic purpose...

Problems solved by technology

If the advertisement needs to be updated, maintenance personnel need to go to each terminal point to use U disk, hard disk, SD / CF card, etc. to copy and replace it in the device, and the maintenance cost is very high

In the past two years, some relatively advanced terminals have appeared, which can send and transmit some information through mobile wireless signals, mainly through telecommunication technologies such as GPRS or CDMA. However, the cost of terminal equipment is relatively high, and monthly payment is required. Information service fees are paid to telecom / mobile operators, and the rate is low, it is almost impossible to transmit video content in real time, and the overall cost remains high
