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...

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-top box

The second solution is to transform the cable TV network itself, and realize the two-way communication of the cable TV network by adding related network equipment. Similarly, the investment in network transformation is huge, and the set-top box also needs to add related Cable Modem modules, which increases the cost.

However, the program is not yet mature enough, and there are still many supporting issues to be resolved

One of the most important problems is the lack of a complete solution to provide technical support for various value-added application services
