High-definition multimedia data transfer device

Abstract

The invention discloses a high-definition multimedia data transfer device. The device comprises a value added service entering process and a value added service quitting process. The value added service entering process comprises the following steps that whether a value added service is in a dormancy state is determined; when the value added service is in the dormancy state, the value added service is awaken; when the value added service is not in the dormancy state, an instance of the value added service is created; and the value added service is executed. The value added service quitting process comprises the steps of setting the value added service in the dormancy state and residing the value added service in a memory. Via the method of the invention, the switching speed between a value added service function and basic functions of a digital TV set is improved on the basis that an existing digital TV value added service system is used.

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
