专利汇可以提供REMOTE CONTROL SYSTEM AND METHOD FOR CABLE TELEVISION SYSTEM专利检索,专利查询,专利分析的服务。并且Each television (120) in a cable television system has a multi-standard receiver for receiving television signals in predefined television signal formats. Hidden from the television viewer is a converter (104) coupling the respective television to a transmission cable (102). The only connection from the converter to the television is a cable connected to the television's cable or antenna input port (130). Each television includes a sensor (122) for receiving wireless command signals. The television's control circuitry (138) ignores wireless command signals not in a first defined set. The converter includes a sensor (132) for receiving a second defined set of wireless command signals. The converter's controller (156) ignores wireless command signals not in the second defined set. The converter's controller responds to wireless channel selection commands by tuning the frequency converter (158) to a respective television channel and/or by transmitting pay-per-view requests to the controller (112) at the head end of the system. A remote controller signal transmitter (126) includes a memory table (237) that stores command and signal format data to use when transmitting wireless commands. Some user commands are transmitted as wireless commands to the television, to the converter or at least one to both the television and the converter.,下面是REMOTE CONTROL SYSTEM AND METHOD FOR CABLE TELEVISION SYSTEM专利的具体信息内容。
