Problems solved by technology

[0003] The above-mentioned interactive services all require an information return channel. The digital TV broadcasting network has multiple methods for data return, such as PSTN MODEM, CABLE MODEM, xDSL, and ETHERNET. The disadvantage is that the speed is slow or network reconstruction is required.

Abstract

A digital TV system carrying out interactive through mobile communication channel is prepared as emitting user up link control information to digital TV front end machine hall local side by digital TV receiving device through radio communication base station and mobile communication network front end machine hall , transmitting digital TV service broadcast to digital TV receiving device by said machine hall local side through CATV network , demodulating and displaying video and visual data information , sending feedback information back to said receiving device by user so as to form a closed loop .

Description

Technical field [0001] The invention relates to a digital television system, in particular to a digital television system interactive through a mobile communication channel. Background technique [0002] With the promotion of digital TV one-way broadcasting and the popularity of set-top boxes, using digital channels to carry out data services will become a new business opportunity for TV operators. Using two-way communication means to carry out fully interactive applications, such as video on demand, ratings statistics, online quiz, mutual text messaging, online chat, interactive advertising, online games, online business, online finance, etc., will make data services a great success . [0003] The above-mentioned interactive services all require an information return channel. The digital TV broadcasting network has multiple methods for data return, such as PSTN MODEM, CABLE MODEM, xDSL, and ETHERNET. The disadvantage is that the speed is slow or network reconstruction is r...
