AUDIO AND VIDEO SYSTEM

摘要

PROBLEM TO BE SOLVED: To control plural audio and video systems without increasing the number of push buttons on a remote controller by incorporating a digital writing face for inputting instruction handwritten by a user to the push button remote controller of a hand held type and communicating with audio and video controller to control the operation of a video display device according to the handwritten instruction. SOLUTION: The user inputs a handwritten instruction on the digital writing face 26 incorporated in the remote controller 24 through the use of a pen 28 to communicate with an audio and video control unit installed on a television receiver 22 through L infrared link 30. The television receiver 22 is provided with a command bar 32 and a user bi-directional panel 34 at a video user interface to display a command from the user. At the time of writing a large 'X', e.g. on the face 26, it is interpreted to be a command for putting off the power source of the television receiver 22 to be displayed.
