Problems solved by technology

[0005] At present, there are two main schemes for the two-way transformation of existing digital TV. The first is to use Ethernet for data return, such as the digital TV system in Hangzhou. This scheme is suitable for establishing Ethernet in the area that has been transformed. Otherwise, it will take a high cost and a long time to build Ethernet, and in this solution, a dual-mode set-top box (advanced set-top box) is required to achieve two-way communication, and the cost of the dual-mode set-top box is significantly increased compared with the ordinary set-to

Embodiment Construction

[0056] The digital TV value-added application service support system provided by the invention is specially developed for the new digital TV network using the existing mobile communication network as the return channel. In the digital TV network, by installing a mobile communication service module on the set-top box, the digital TV network is combined with the mobile communication network, and the SMS or GPRS / CDMA channel is used as the information return channel to realize the two-way interactive digital TV service.

[0057] As shown in FIG. 1 , the system provided by the present invention for implementing digital TV value-added application services mainly includes two parts: a front-end system module and a set-top box. The front-end system module is used for the production, management and broadcasting of value-added services. It mainly includes offline editing module 3 and online editing module 5 to realize WYSIWYG, and audit module 4 to ensure the safety and legality of page b...

Description

technical field [0001] The invention relates to a value-added application service support system for realizing digital TV value-added services, and also relates to a method for realizing value-added application services by using the system, which belongs to the technical field of digital TV. Background technique [0002] Digital TV is a digital TV broadcasting system that digitizes the entire broadcast link from TV signal collection, editing, dissemination, and reception. Compared with traditional analog TV, its advantage is that it can basically realize high-fidelity transmission, that is, there is no difference between the image and sound quality and the studio effect. At the same time, due to the use of data compression technology, the channel for transmitting a set of analog programs can be used to transmit 4~ 6 sets of digital TV programs greatly reduce launch and transmission costs. In addition to bringing more channels and better image quality, digital TV can also ca...
