Embodiment Construction

[0031] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0032] The invention adds a "cable digital TV and network service control module" to the cable TV head end system to realize the integration of the cable digital TV and network service at the head end. As shown in Figure 1, build a digital TV system framework with two-way service triggering, which includes the following main relevant parts:

[0033] Wherein "EPG editing module 15" generates EPG information, and provides this information to "cable digital TV and network service control module 17" and "PSI / SI server 16";

[0034] Among them, the "cable digital TV and network service control module 17" analyzes EPG information, controls the "cable digital TV content server 11" and "cable network service server 12", thereby integrating digital TV and network service content;

[0035] Wherein the "wired network service server 12" specifically organi...

Abstract

The invention discloses a digital TV content-based bidirectional service triggering method and a digital TV system having bidirectional service triggering function. And the method comprises: 1) inserting related network service information in EPG information table of wired digital TV; 2) analyzing EPG information and controlling 'wired digital TV content server' and 'wired network service management server'; 3) adding interactive service in terminal receiver. And the system comprises wired head end and multiple terminals, interconnected through wired TV net, where the wired head end comprises wired digital TV content server, wired network service management server, broadcasting channel modulator module, interactive data channel modulating and demodulating module, EPG edition module, PSI / SI server, and a wired digital TV and network service control module which implements fusion of wired digital TV and network service at the head end. And the invention improves flexibility, interactiveness and entertainment of the wired digital TV system.

Description

technical field [0001] The invention relates to cable television network technology, in particular to a two-way service triggering method based on digital TV content and a digital TV system with two-way service triggering. Background technique [0002] The transformation of the two-way network of cable television is currently in progress. There are two logical networks on the cable TV network after the two-way transformation: the one-way broadcast network using the DVB standard to transmit digital TV and the two-way data network realized by the DOCSIS protocol. So far, the two networks still operate independently without any connection and sharing. Due to the mutual independence of the two logical networks, the end users of the cable network cannot obtain the breakthroughs in content and presentation forms brought about by the integration of digital TV and data networks. [0003] If the one-way broadcasting network using the DVB standard to transmit digital TV and the two-...
