Embodiment Construction

[0024] Hereinafter, with reference to the accompanying drawings, the present invention will be described in more detail in combination with embodiments.

[0025] FIG. 1 is a block diagram of the connection state between the image display device and peripheral devices of the present invention.

[0026] Referring to Fig. 1, image display equipment (such as television set TV) 100 is connected with peripheral equipment, such as video cassette recorder (VCR) 200, digital video disc player (DVD) 300 and set-top box (STB) 400, and they are mutually Communication is formed through the 12C bus.

[0027] In addition, a basic program capable of performing I2C bus communication is loaded on a microprocessor included in each peripheral device including a television (TV). If a predetermined command signal is input to the above-mentioned peripheral equipment through a remote controller, etc., the microprocessor included in the above-mentioned peripheral equipment will automatically set the ...

Abstract

A communication system between image display device and peripheral device comprises image display device, at least one peripheral device connected to said image display device through 12C bus and voltage level regulation unit for regulating voltage level inputted to two said devices by 12C bus according to identification scope of microprocessor.

Description

technical field [0001] The present invention relates to a communication system and method between an image display device and peripheral devices, in particular to a communication system and method for detecting the current state of many peripheral devices connected to the image display device and automatically setting the state desired by the user . Background technique [0002] In traditional technology, if the image display device and peripheral equipment, such as video tape box recorder {VCR (video cassette recorder)}, digital video disc player {DVD (digital versatile disc)}, set-top box {STB (set top box) and other equipment If they are connected, the working environment of the image display device and the surrounding equipment needs to use separate remote controllers, etc., and the user must set the connected surrounding equipment one by one. [0003] For example, if the user connects a video tape cassette recorder (VCR) in a television set (TV) to view and listen to v...
