Embodiment 1

[0077] Embodiment 1. The high-fidelity Bluetooth speaker is not online.

[0078] When the smart terminal smartphone is not online, or the high-fidelity Bluetooth speaker is not plugged in or fails, in the playback device list, the second playback terminal connected to the smartphone is offline, that is, the high-fidelity Bluetooth speaker is displayed as offline and cannot be connected High-fidelity Bluetooth speakers are used to play audio, so according to the priority, only the first player TV can be selected to play audio and video.

[0079] At this time, the NVR sends the audio and video to the first player TV to play the audio and video.

Embodiment 2

[0080] Embodiment 2, the high-fidelity bluetooth speaker is online.

[0081] Here, it is found that the Blue_Sound1 (Bluetooth speaker) of the smart phone is preferred for audio playback, and the video data is decoded and played through TV (television).

[0082] At this time, the video can be sent to a TV with high image quality for playback, and has a larger screen, and the audio can be forwarded to a high-fidelity Bluetooth speaker through a smart phone for playback, with higher sound quality.

[0083] For embodiment 2, the video playback device of priority is the first playback terminal, and the audio playback device of priority is the second playback terminal, and the NVR includes the following steps when it needs to play the audio and video stream of IPC:

[0084] 1) The NVR obtains the audio and video data stream, and performs high-frequency modulation and encoding on the audio data stream.

[0085] The NVR obtains an audio and video data stream of the IPC through the n...

Abstract

The invention discloses an audio and video playing method and apparatus in video monitoring, which are applied to a video monitoring system. The audio and video playing method comprises the steps of firstly, receiving registrations of a front-end device, a first playing end and an intelligent terminal in the video monitoring system, and according to a request message sent after the intelligent terminal is connected with a second playing end, establishing a playback device list corresponding to the first playing end and the second playing end; and then according to the established playback device list, selecting the first playing end or / and the second playing end to play an audio and a video which are acquired by the front-end device. The apparatus disclosed by the invention comprises a registration module and a playing selection module. According to the method and the apparatus which are disclosed by the invention, playback devices with the optimal effect can be selected to respectively play the video and the audio, meanwhile, synchronization of different playback devices also can be implemented, the high-quality devices are sufficiently utilized, and the best user experience is provided.

Description

technical field [0001] The invention belongs to the technical field of video monitoring, and in particular relates to an audio and video playing method and device in video monitoring. Background technique [0002] With the popularization of the Internet, video surveillance has been widely used in family, education, business, medical treatment, public places, etc. When playing the audio and video obtained by the IPC of the front-end device, it is necessary to ensure the clarity of the video playback and the sound quality of the audio playback. [0003] At present, when performing video playback, commonly used choices are high-definition televisions or other high-definition display devices. The audio playback can be played using the audio playback system that comes with the high-definition television. With the emergence of high-fidelity bluetooth speakers, high-fidelity bluetooth speakers apply bluetooth technology to traditional audio to achieve wireless audio transmission,...
