Embodiment Construction

[0033] figure 1 It is a device block diagram of a wireless transmission channel control method according to a preferred embodiment of the present invention. This device uses a transceiver 110 installed inside a host 100 to receive identification signals sent by a plurality of different wireless controllers 120 , wherein each identification signal includes an identification code, which is sent to the processor 130 inside the host 100 for the identification step, wherein the host 100 further includes a memory unit 140, which is used to store the channel list and authority corresponding to the identification code In addition, it also includes a comparison unit 150. When the transceiver 110 receives identification signals sent by more than one wireless controller 120 at the same time, the comparison unit 150 compares the identification codes corresponding to these identification signals. According to the size of the authority level, the channel list corresponding to the identifica...

Abstract

The invention relates to a channel control method for wireless transmission. The method adopts a transceiver to receive identification signals sent by a plurality of different wireless controllers. Due to the wireless transmission structure, it can automatically switch and set the authority range of the channel that can be watched, and can compare the authority range of multiple users according to the identification code corresponding to the received identification signal, and provide a suitable channel The directory is for users to watch, and in addition, users are provided with multiple sets of different channel directories to achieve the purpose of diversity, protection, and convenience.

Description

technical field [0001] The present invention relates to a channel control method, and in particular to a channel control method utilizing wireless transmission. Background technique [0002] Due to the increasing popularity of cable TV, the number of TV channels has also increased. Just like the rating system for movies for each age group, TV also needs to formulate a suitable channel list for each audience according to the program content. The known technology is to provide protection measures for channel classification through some code locking functions. The more common one is to use address lock code, that is, to use signal processing technology to digitize the image and sound of a specific channel. Viewers must use cable TV The digital TV receiver provided by the industry must be decoded to restore the signal. In this way, parents can set a password in the digital television receiver at home, and the password must be input before watching a program, otherwise the progr...
