Device and method of remote control signal processing, set top box (STB) and television signal transmission system

Abstract

The invention discloses a device and a method of remote control signal processing, a set top box (STB) and a television signal transmission system. The device of the remote control signal processing comprises a first remote control signal receiving device and a signal processing device, the first remote control signal receiving device is used for receiving and demodulating first remote control signals from a first remote controller, and the signal processing device is used for receiving the demodulated first remote control signals through a first interface, coding the demodulated first remote control signals, generating first control signals, and sending the first control signals to a STB controller. The device of the remote control signal processing further receives demodulated second remote control signals from a second remote control signal receiving device through a second interface, codes the demodulated second remote control signals, generates second control signals, and sends the second control signals to the STB controller. The device and the method of the remote control signal processing, the STB and the television signal transmission system can achieve that television programs can be watched at the same time with two television sets using one STB.

Description

technical field [0001] The invention relates to the field of digital cable television, in particular to a remote control signal processing device, method, set-top box and television signal transmission system. Background technique [0002] In the prior art, one set-top box can only receive the remote control signal of one TV remote controller. If there are two TV sets in the user's home and need to watch TV programs at the same time, two set-top boxes or a digital TV sharer are needed to realize it. [0003] For the situation of using two set-top boxes, although the problem of two TV sets watching different TV programs can be solved, the cost of use is higher due to the need to purchase one more set-top box; for the situation of using a digital TV sharer, although Two TVs use one set-top box to watch TV programs, but the two TVs can only watch the same TV programs. The problems mentioned above are mainly due to the fact that the existing set-top box can only receive and pro...

AI Technical Summary

Problems solved by technology

[0003] For the situation of using two set-top boxes, although the problem of two TV sets watching different TV programs can be solved, the cost of use is higher due to the need to purchase one more set-top box; for the situation of using a digital TV sharer, although Two TVs use one set-top box to watch TV programs, but the two TVs can only watch the same TV programs

The above problems exist mainly because the existing set-top box can only receive and process one remote control signal, so it cannot support two TV sets to watch different TV programs with only one set-top box
