[0044] In the first embodiment, the switching method of the signal source includes:

[0045] Step S10, when the detection instruction is detected, detect whether there is a signal input to each signal source channel of the multimedia playback device;

[0046] The multimedia playback device detects the detection command in real time. When the multimedia playback device detects the detection command, it detects whether each signal source channel of the multimedia playback device has signal input, so as to confirm which signal source channels have signal input and which signal source channels have no signal. enter. The multimedia playback device does not detect the detection command, does not perform any operation or continues to detect the detection command. In this embodiment, whether there is a signal input to the signal source channel can be determined through the status signal fed back by the signal source channel. For example, when the signal source channel has a signal in...

Abstract

A signal source switching method is disclosed. The method comprises the following steps: upon detecting a test command, testing whether each signal source channel of a multimedia playback device has signal input; obtaining the video signals of signal source channels having signal input; on the basis of preset caching rules, encoding and caching to a memory the video signals obtained; and, upon detecting a switch signal source command, reading from the memory the video signal corresponding to the post-switch signal source channel, and displaying the video signal. A signal source switching device is also disclosed. In the signal source switching method and device of the present invention, when switching signal source channels, the post-switch image signal may be displayed more quickly, thereby greatly reducing visible freezing when switching signal source channels, and thus improving the visual effects of the multimedia playback device.

Description

technical field [0001] The invention relates to the field of display equipment, in particular to a signal source switching method and device. Background technique [0002] At present, a television, as an entertainment terminal in a living room, not only undertakes the use of the entertainment function of the television itself, but also serves as a display terminal for various peripherals because the television has multiple peripheral signal ports. With more and more peripheral products and more and more functions, users often switch signal sources to play different video content. However, when the current TV sets switch signal sources each time, they need to exit the playback process of the signal source before switching, then call the initialization data of the signal source after switching, and then display the video data of the signal source after switching. The switching process of the signal source is slow and the signal display is slow, thus forming a visual stop when...
