Embodiment Construction

[0040] according to figure 1 The specific structure and working process of the present invention will be described in detail. refer to figure 1 The image display device and external device connection state diagram of the beneficial example of the present invention shows that the CPU (central processing unit) (102) of the image display device (100) not only controls the image display device (100) as a whole, but also The first and second external devices (200, 210) are controlled. The first memory unit (104) stores the control program and various information of the above-mentioned CPU (102), and at the same time stores the working status of the first and second external devices (200, 210) according to the beneficial example of the present invention. The user interface (106) functions as an interface between the user and the CPU (102). The external device interface and control unit (108) acts as an interface between the above-mentioned CPU (102) and the first and second exter...

Abstract

When each time of asking for altering input mode, the previous input mode is checked for deciding if it is an external input mode. If yes, it is altered into a request of external input mode. Otherwise, the external device corresponding to the external input mode is checked for deciding if it is at idle state. If yes, relieves the idle state, and instructs it to display. If the request for altering is not a request for altering to external input mode, or an instruction of displaying is offered to external device. Then input mode before altering is checked for deciding if it is an external mode. If yes, then instructs the external device corresponding to the external input mode to pause.

Description

technical field [0001] The invention relates to an image display device, in particular to a method for controlling external equipment of the image display device. Background technique [0002] Recently, high-performance image display devices such as digital television receivers accept various external inputs and provide users with high-quality images. [0003] As the types of external devices that can be connected to the image display device increase, the number of external devices that users need to use continues to increase, so many inconveniences occur in use. [0004] In detail, it often happens that if the path of AV (video and audio) signal input uses multiple image display devices, then in the process of playing the AV signal through any of the multiple external devices, if you want to temporarily output AV signals input from other paths, and then replay AV signals through the external equipment used initially. [0005] During the process of temporarily outputting t...
