Embodiment Construction

[0030] Such as figure 1 As shown, in the structural block diagram of the present invention, it includes a channel opening judging module 11 , a control module 12 , an instruction receiving module 13 and a channel sequence judging module 14 .

[0031] When the TV is turned on for data initialization, the control module 12 sends a control command to start the channel opening judgment module 11, and the channel opening judgment module 11 is used to judge whether the external device channel determined by the channel sequence judgment module 14 is in the open state.

[0032] The control module 12 is used to switch the peripheral channel to the current working channel of the TV when the channel opening judging module 11 confirms that the channel is open. The control module 12 monitors the connection status of each channel in real time. When it detects that more than two peripherals are connected to the TV, and the number of peripheral connections changes from the previous time, a ne...

Abstract

The invention relates to an automatic switching method of circumscribed equipment of a television set. The method comprises the following steps: a. whether the present circumscribed equipment channel is in the state of opening is judged; if yes, the step b is executed; if no, the step d is executed; b. the circumscribed equipment channel is switched into the present working channel; c. whether the command of selecting the present working channel is received is judged; if yes, the switching is stopped; if no, the step d is executed; d. whether the present channel is the last channel in the channel monitoring sequence is judged; if yes, the first circumscribed equipment channel in the channel monitoring sequence is taken as the present circumscribed equipment channel and then the step a is executed; if no, the next circumscribed equipment channel in the channel monitoring sequence is taken as the present channel and then the step a is executed. The television set in the method can automatically judge which channel of the television the circumscribed equipment accessed by a user is in without being judged by the user.

Description

technical field [0001] The invention relates to television technology, and more specifically relates to a method for automatically switching external equipment connected to a television and the television. Background technique [0002] When the TV is in use, because it often needs to connect external audio and video playback equipment, such as DVD player, VCD player, set-top box and DV player, etc., there are multiple input channels in the TV set, such as AV input channel, S terminal input channel, two-way component (YPbPr / YCbCr) input channel, SVHS input channel, CVBS input channel, HDTV input channel, etc. [0003] When multiple external devices are connected to the TV at the same time, the existing TV generally adopts two processing methods. One is to immediately switch from the current input channel to the new one when there is a new signal input from the external device. input channel; or switch to the previous memory channel when the current channel is closed.
