Implementation method capable of switching to digital television value-added service

Abstract

The invention discloses an implementation method capable of switching to a digital television value-added service, and the method comprises a process of entering the value-added service and a process of quitting the value-added service. The process of entering the value-added service comprises the following steps: judging whether the value-added service is in a state of dormancy or not; wakening the value-added service if the value-added service is in the state of dormancy; creating a value-added service instance when the value-added service is in a non-dormant state; and performing the value-added service. The process of quitting the value-added service comprises the steps: setting the value-added service in the state of dormancy and enabling the value-added service to stay in a memory. The method provided by the invention increases the switching speed between a value-added service function and the basic functions of a digital television on the basis of a conventional digital television value-added service system.

Description

technical field [0001] The present invention relates to the field of network communication, and more specifically relates to a wireless transmission device for realizing multiple signal common use by using wireless broadband network technology. Background technique [0002] With the development of communication technology, telephone technology, data network technology and cable TV technology have developed quite maturely as single service technologies. [0003] For the telephone technology mainly used for voice services, the user's telephone terminal is connected to the distribution box through a cable, and the distribution box is connected to the telecom core network through a cable. For ordinary telephone users, they can only receive voice signals through telephones and carry out voice services. At present, computers can be connected through access devices such as asymmetric digital subscriber lines to receive data services provided by Internet service providers, but the d...

Problems solved by technology

The current TV network adopts the broadcast mode, and users can only receive TV programs through the access devices such as amplifiers and splitters, and cannot perform two-way communication, and cannot carry out voice services and data services.

[0006] To sum up, the current types of telecommunications services are networked separately, and services are connected to dedicated terminals through dedicated access devices, resulting in waste of line resources. In some areas, repeated networking is carried out, and users carry out various In service, different access devices are required for different services, which increases user costs
