Problems solved by technology

One solution is to configure a set-top box on each display terminal, which will obviously cause a great waste of resources
Another solution is to transform the existing home wiring structure to meet the requirement that one set-top box can provide multiple display terminals for viewing, but for the residents who have completed the renovation, the complexity of such transformation will also be quite large

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Fig. 1 shows the overall structure of the system embodiment of the present invention. Please refer to shown in Fig. 1, the TV program signal (taking DVB signal as example) that the operator releases is received by the RF connecting line 11 that set-top box 12 connects, sends out RF signal after processing such as vestigial sideband modulation through set-top box 12, and it is received Modulated at a fixed frequency. After being distributed by a distributor 13, the output RF signal is sent to the other two rooms respectively. The RF signal is transmitted in the RF network distribution system, which consists of the original indoor RF wiring network. Change the original network signal distribution platform into the current set-top box modulated signal release platform. The communication between the remote controller 15 and the set-top box 12 is c...

Abstract

The invention uses one set-top box and one remote controller to provide TV watching for multi rooms. It comprises: a signal receiving sub-system for receiving program signals from service provider; a signal broadcast sub-system for converting the received program into two routs of AV signals; one route is used by display terminal, and another route is modulated into RF signals to output through vestigial sideband; an operation sub-system for controlling the operation of set-top box by the remote controller based on a preset wireless protocol; a RF -signal broadcasting network for sending RF signals from signal broadcast sub-system to each display terminal.

Description

technical field [0001] The invention relates to a home multimedia center system, in particular to a home multimedia center system in which one set-top box provides multiple display terminals for viewing. Background technique [0002] In existing home multimedia solutions, one set-top box is usually configured on one television set. There are often multiple display terminals (television sets) in the solution of a home multimedia entertainment center. One solution is to configure a set-top box on each display terminal, which will obviously cause a great waste of resources. Another solution is to transform the existing home wiring structure to meet the requirement that one set-top box can provide multiple display terminals for viewing, but for the residents who have completed the decoration, the complexity of such transformation will be quite large. [0003] At present, video and audio vestigial sideband modulation technology has been used very maturely in cable TV broadcast ...
