Embodiment Construction

[0027] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0028] Such as figure 1 As shown, the present invention includes:

[0029] RF remote control: with a radio frequency chip, used to transmit the key value pressed by the user, and the transmission form is a 433MHZ wireless signal.

[0030] RF module: RF signal forwarding module, which is a bridge to realize communication between RF remote control, set-top box, and central office gateway. Port to communicate with the I2C protocol.

[0031] Signal separator: For downlink data, it is used to separate the CATV signal from the downlink 433MHz signal, and transmit the 433MHz signal through the antenna; for uplink data, it is used to receive the 433MHz signal to the central office gateway through the antenna.

[0032] Central office: The central office equipment interacts with the server through the RJ45 port, and uploads and uploads data; the CATV signal enters t...

Abstract

The invention relates to a system and a method of external interactive intercommunication based on radio-frequency technique. The system comprises a radio frequency remote controller, an RF (Radio Frequency) module, a signal separator and a local side gateway. The RF module is used for transmitting radio frequency signals, and communicates with the radio frequency remote controller and the local side gateway in a wireless signal manner. The signal separator is used for separating CATV signal and descending signal and simultaneously emitting the signals out through an antenna for descending data, and is used for collecting the signals to the local side gateway through an antenna for upstream data. The local side gateway is used for converting network signal sent from a server and carrying out mix output with the CATV signal for the descending signal, and is used for converting the signal into Ethernet signal and sending to the server for the upstream data. The system and the method provide a convenient and reliable video-on-demand solution with low power consumption, low cost and good user experience for bidirectional rebuilding of cable television network.

Description

technical field [0001] The invention belongs to the technical field of electronic information, and relates to an external interactive two-way communication system and method based on radio frequency technology. Background technique [0002] In the past few years, video-on-demand technology based on two-way cable TV network has created the video-on-demand myth. Since the two-way high-definition video-on-demand set-top box products based on Ethernet technology were put into the market, the two-way TV network products have gradually attracted the attention of many consumers with their high transmission rate, rich video-on-demand sources, and very attractive related derivative services. However, the two-way video-on-demand technology has not attracted the admiration of the cable TV industry because of its high price, the need for broadband resources, and the huge amount of network changes to the existing links. [0003] The traditional view holds that video on demand needs to i...
