Abstract

A remote controller consists of operation unit with multiple key, ultrasonic and radio signal emission unit for emitting radio signal and ultrasonic signal when one of operation keys is pressed down in order to map position of remote controller to be cursor displayed on screen and control unit for controlling said operation unit and said ultrasonic and radio signal emission unit.

Description

technical field [0001] The present invention relates to a remote controller, video equipment, remote control method and system, in particular to a remote controller, video equipment, remote control method and system based on ultrasonic and wireless signal distance measurement, so as to realize channel selection of TV programs, text input, etc. Features. Background technique [0002] With the development of digital TV technology and the increase of digital TV broadcasting programs, digital TV gradually enters our life. An important feature of digital TV is that we can choose our favorite TV programs at any time. But, for the vast number of users who are accustomed to traditional TV remote control operations, it is not an easy task to input and specify their favorite programs. Users often need to select a specific function key from the numerous and densely arranged keys on the remote control. In order to complete this operation, unskilled users often need to keep their head...
