Embodiment 1

[0023] A multi-channel radio and television interactive information on-demand system includes a broadcast server, a TV set and a user sending controller, and is characterized in that it also includes a signal receiving server, an information editing computer, and a cable TV modulator, and the signal receiving server and the information editing computer pass through the The local area network is connected to the broadcast server, and the broadcast server connects the video signal and audio signal to the cable TV modulator, and the cable TV modulator outputs an analog radio frequency (RF) signal connected to the TV through the cable TV network, and the user sends the controller to send The control signal is received by the signal receiving server to control the broadcast server.

[0024] Uplink control signal transmission adopts a wireless transmission method: the signal receiving server is composed of an identification base station, a repeater connected in series with the identi...

Embodiment 2

[0086] The structure and use process of embodiment 2 are basically the same as embodiment 1, the difference is:

[0087] Uplink control signal transmission adopts wireless and wired transmission mode: the signal receiving server is composed of identification base station, repeater connected in series with identification base station, digital transmission station, identification host and server, each controller (RFID), identification base station The controller (RFID) used by each user sends a control signal to the corresponding identification base station set up in the residential area for information collection, and the identification base station centralizes the collected information , orderly management, through the repeater behind it, it is transmitted to the cable TV optical node of the community in a wired manner, and then transmitted to the main control station of the cable TV central computer room through the optical cable. The host transmits data to control the server...

Embodiment 3

[0089]The structure and use process of embodiment 3 are basically the same as embodiment 1 and embodiment 2, the difference is:

[0090] After the overall translation of radio and television digitization, channel resources have been expanded. At that time, as long as the audio and video signals of the broadcast server are converted into digital signals, the ordinary digital TV set-top box (one-way) is connected with the TV set through the cable TV network.

Abstract

The invention discloses an interactive information on-demand system of multichannel broadcast television, which comprises a broadcast server, a television, and a user delivery controller. The invention is characterized in that the system further comprises a signal receiving server, an information editing computer, and a cable television modulator. The signal receiving server and the information editing computer are both connected with the broadcast server, and the broadcast server is connected with the cable TV modulator. The cable TV modulator exports simulating RF signal which is connected with a television set through cable TV network, the user controls the signal to be received by the receiving server through the user delivery controller then the signal is transferred to the receive server, wherein the broadcast server is controlled by the signal receiving server. Wireless transmission mode or wireless and wire transmission mode is used in the transmission of the control signal. The invention does not need to change the existing cable TV network into bidirectional network, does not need to have a bidirectional digital television set top box, applies household television sets as multimedia display terminals, and can be operated by users through using a controller costing more than RMB100, which has the advantages of powerful function and low price.

Description

technical field [0001] The invention relates to a radio and television system, in particular to a multi-channel radio and television interactive information on-demand system. Background technique [0002] At present, my country's radio and television department is promoting the overall digital translation of radio and television transmission, that is, the overall conversion from the current analog transmission to digital transmission, which is what we usually call digital TV. After digital shifting of broadcasting and TV, the functions will be greatly expanded: the quality of digital TV image and sound has been greatly improved, reaching the level above that of a DVD player; it can be easily connected with various external information sources, and can be connected on the same channel. Realize the transmission and access of different services within the network, so that the TV media has changed from a single TV program transmission to a broadband comprehensive information ser...
