Embodiment Construction

[0021] figure 1 It is a system diagram showing the TV remote control 10 and the TV 20 according to the preferred embodiment of the present invention. The TV remote control 10 and the TV 20 perform all control and data communication through the wireless communication channel 30 . The wireless communication channel 30 between the TV remote control 10 and the TV 20 of the present invention is not affected by the relative position and angle of the TV 20 and the TV remote control 10, and can maintain the TV remote control 10 and the TV remote control 10 within a specific space range at the same time. Wireless communication between television sets 20 . That is to say, in the present invention, if a wireless communication channel meets the aforementioned conditions such as the wireless communication channel 30 , it is called an undirected wireless communication channel within the aforementioned specific space range. For example, the above-mentioned specific range is 10 meters, and...

Abstract

This invention discloses a directionless radio communication TV remote controller used in controlling a TV including a radio communication unit and a sound output interface, in which, the communication unit is used in setting up a directionless radio communication channel, said sound output interface is coupled to the communication unit to receive sound data from the TV via the unit and the channel.

Description

technical field [0001] The invention relates to a TV remote controller, in particular to a TV remote controller capable of non-directional wireless communication with the TV set. Background technique [0002] Traditionally, the wireless communication of the TV remote control adopts infrared (Infrared) signal technology. In terms of controlling the basic functions of traditional TV, such as channel selection, volume control, power switch, etc., the infrared signal technology can already meet the actual operation of the TV remote control. [0003] In the trend of digital TV integrating home appliances, the functions of digital TV will continue to improve. Therefore, the wireless communication capability between the TV remote control and the TV needs to be relatively enhanced. [0004] However, an infrared signal channel is used for communication between the traditional TV remote controller and the TV. For example, if a TV remote control including an infrared transmitter comm...
