An embodiment of the present invention provides a broadcast receiving apparatus, referring to fig. 2, the broadcast receiving apparatus 100 includes: a DAB module 11, an FM module 12 and a processing module 13;
wherein, the DAB module 11 is used for receiving DAB signals;
an FM module 12 for receiving an interrupt signal;
the processing module 13 is configured to play the DAB signal received by the DAB module in the DAB mode, and when the FM module 12 receives the interrupt signal, control to maintain the DAB mode, and play the interrupt signal received by the FM module 12.
Because the broadcast receiving device does not exit the DAB mode to jump to the FM mode when playing the interrupt signal, the mute operation is not triggered, so that the broadcast receiving device can normally play the sound when playing the interrupt signal, and the problem that the broadcast receiving device cannot play the sound within a period of time (namely within the mute time length) when playing the interrupt signal, thereby causing the hearing violation and sense to the user is solved.
In the embodiment of the invention, the DAB signal refers to an index broadcasting signal. The FM signal refers to an analog broadcast signal.
Optionally, the interrupt signal includes an audio signal and/or a video signal. It should be noted that, in the embodiment of the present invention, the video signal may include text, pictures, dynamic video, and the like.
In the embodiment of the invention, the content of the interrupt signal can comprise natural disaster information, emergency early warning information and the like, and the interrupt signal can be news or alarm broadcasting generally.
In the embodiment of the invention, if a natural disaster or an emergency occurs under the condition that DAB is seamlessly connected to FM RDS, the radio station (English name: this Net, english abbreviation: TN) is possibly interrupted so as to play interruption information (namely corresponding natural disaster information, emergency early warning information and the like) and inform a user of the occurrence of the natural disaster, the emergency and the like.
The interrupt signal is an FM signal, which is typically issued when DAB is seamlessly connected to the FM RDS mode.
Optionally, the processing module 13 is further configured to calculate a delay time of the FM signal with respect to the DAB signal, and superimpose the delay time on the interrupt signal.
As shown in fig. 3, the FM signal is typically earlier than the DAB signal, so there is a time difference between the FM signal and the DAB signal (delay time X as shown in fig. 3).
Since the time difference shown in fig. 3 exists, in the embodiment of the present invention, when the processing module 13 plays the interrupt signal (the interrupt signal is an FM signal) in the DAB mode, the delay time required by the FM signal with respect to the DAB signal (the delay time may be greater than or equal to the time difference between the FM signal and the DAB signal) is calculated first, and then the delay time is superimposed on the interrupt signal. Therefore, the interrupt signal can be completely and normally played, and partial information is prevented from being deleted when the interrupt signal is played.
When the interrupt signal includes an audio signal and a video signal, the delay time is superimposed on the audio signal and the video signal simultaneously and synchronously to ensure synchronization of the audio signal and the video signal.
