Title: SIGNAL SOURCE SWITCHING CONTROL METHOD AND DEVICE
Abstract:
The present invention discloses a signal source switching control method. The signal source switching method comprises: detecting a signal source signal when receiving a signal source switching instruction; when detecting a signal source signal, locking the detected signal source signal; determining whether the signal source of the locked signal is the signal source corresponding to the currently received signal source switching instruction; and if the signal source of the locked signal is the signal source corresponding to the currently received signal source switching instruction, setting images and sound corresponding to the signal source and playing the signal source signal. Also disclosed is a signal source switching control device. The signal source switching control method of the present invention is able to effectively prevent the inconsistency between the signal source of a locked signal and the current signal source during quick signal source switching.
