Problems solved by technology

However, there are two defects in the way of GPRS module positioning: 1. The cost of GPRS module is relatively high; 2. The GPRS module needs the support of mobile operator's base station, and there may be no base station in remote areas
In practical applications, this one-way system cannot enable the end user

Embodiment Construction

[0025] The solution of the present invention will be described in detail below in combination with the preferred embodiments thereof.

[0026] The invention adopts the RDSS method, which can not only realize the positioning of the user terminal, but also realize the data interaction with the radio and television operators, and all data channels are realized through the LNB.

[0027] In RDSS (Radio Determination Satellite Service, satellite radio determination service), the distance measurement and position calculation from the user to the satellite cannot be completed independently by the user itself, and must be completed by the external system through the user's response. Its characteristic is that through the user's response, while completing the positioning, the user's position report to the external system is completed, and the integration of positioning and communication can also be realized. my country's Beidou first-generation satellite positioning system is RDSS, and ...

Abstract

The invention relates to an LNB module used for receiving satellite television signals and a corresponding satellite television set top box, and an information interaction method applied to the satellite television set top box. The LNB module comprises a live telecast satellite signal antenna and an LNB circuit, and further comprises a RDSS circuit and a RDSS signal transmitting and receiving antenna. By using the LNB module, the connection between the satellite television set top box and the LNB is simple, and the regional limitation problem and communication interaction function of the satellite television set top box can be effectively solved. The LNB module is particularly applicable to remote regions without 3G signal coverage, and can also provide emergency communication in some in emergency circumstances.

Description

technical field [0001] The invention relates to an LNB module for receiving satellite TV signals, a corresponding satellite TV set-top box, and an information interaction method for the satellite TV set-top box. Background technique [0002] With the development of information technology, live broadcast star set-top boxes have been greatly promoted in rural areas, but due to counterfeit phones in the market, there are more and more black boxes, and even boxes that are tendered by the state are used in cities, impacting local cable digital set-top boxes market, causing confusion to the market and management. [0003] The Chinese patent application "Satellite TV Set-top Box" with the application number of 201210093138.1 discloses a satellite TV set-top box, including a processor, a radio frequency module, an access device, a power supply, and input and output devices. The GPRS electronic device also includes a GPRS antenna, and the GPRS The antenna includes: a dielectric subs...
