Method and system for information interaction based on wireless digital network

Abstract

The invention discloses a method and a system for information interaction based on a wireless digital network, relating to the technical fields of wireless digital communication and wireless digital televisions. The method comprises the following steps: an information terminal is internally provided with a wireless communication module, a wireless digital television module and a browser, a user selects content to be inquired in the browser of the information terminal by a remote controller, a query request is sent to a background gateway by the wireless communication module of the information terminal through a wireless communication network, the legality of the request of the information terminal is examined and verified by the background gateway through a BOSS (Business Operation Support System), the query request is sent to a content server after being examined legal, obtained information content is sent to a push server, the push server transfers an addressing push information to a wireless digital television transmission base station, the information content is sent to a memory of the information terminal of a user through a wireless digital television network, and the information content in the memory is played by the information terminal and displayed on television. According to the technical scheme disclosed by the invention, the user obtains the information content through the wireless digital network and watches on television.

Description

technical field [0001] The invention relates to the technical fields of wireless digital communication and wireless digital television, in particular to a method and a system for obtaining information content through interactive operation in combination with technical advantages of wireless digital communication network and wireless digital television network. Background technique [0002] The information superhighway is the basis for the implementation of informatization. Around the three basic network systems of broadcasting network, telecommunication network and information network, how to build a low-cost "three-network integration" information superhighway has become an important prerequisite for informatization. [0003] Optical fiber and broadband access to the home is a means to solve informatization, but the investment cost of optical fiber and broadband access to the home is huge, the construction time is long, and maintenance is difficult. It is very difficult to p...

AI Technical Summary

Problems solved by technology

[0006] (2) The wireless digital communication network has interactive advantages, but the frequency is narrow and the transmission rate is low. The rate of WCDMA is ≈ 2Mbps, the rate of CDMA2000 is ≈ 2.4Mbps, and the rate of TD-CDMA is ≈ 3.84Mbps;

[0008] (4) After the wireless TV network adopts the national terrestrial digital TV transmission standard, the data transmission rate can reach 32Mbps when modulated by 64QAM, and users can enjoy wireless data high-speed download service. lack
