Problems solved by technology

However, in the process of audio and video playback, the Bluetooth signal will change. For example, the movement of the audio source device will cause the Bluetooth signal to change. As a result, the Bluetooth signal may become weaker and the transmission quality may deteriorate, which may lead to a decrease in the quality of music playback. For example, Playing music is interrupted or there is noise

Embodiment 1

[0022] figure 2 It is a schematic flowchart of the playback control method in the audio and video playback system provided by Embodiment 1 of the present invention. This method is applicable to the case where the playback device switches from the Bluetooth audio and video data sent by the audio source device to play the same network audio and video data as the Bluetooth audio and video data downloaded from the Internet. This method can be controlled by the playback in the audio and video playback system device to execute. The device can be implemented by software and / or hardware, and can be configured in a playback device that establishes a bluetooth connection with the audio source device. Such as figure 2 As shown, the method includes:

[0023] Step 101. When the preset playback switching condition is detected, download the network audio and video data corresponding to the current audio and video according to the audio and video information corresponding to the current ...

Embodiment 2

[0048] image 3 It is a schematic flowchart of the playback control method in the audio and video playback system provided by Embodiment 2 of the present invention. This embodiment is based on Embodiment 1. After the step of switching and playing the network audio and video data, an increase is added: when it is determined that the preset playback switching conditions are not satisfied, the playback of the network audio and video data is terminated, and the audio and video data is received and played from the audio source device. Bluetooth audio and video data.

[0049] Correspondingly, such as image 3 As shown, the method of the present embodiment includes:

[0050] Step 201. When the preset playback switching condition is detected, download the network audio and video data corresponding to the current audio and video according to the audio and video information corresponding to the current audio and video received by the audio source device received by the current playbac...

Abstract

The present invention discloses a playing control method and device in an audio-video playing system, wherein the method comprises the steps of when a preset playing switching condition is detected, and according to the audio-video information of a current audio-video corresponding to the Bluetooth audio-video data sent by a sound source device and received by a current playing device, downloading the network audio-video data corresponding to the current audio-video; stopping receiving the Bluetooth audio-video data sent by the sound source device, and switching to play the network audio-video data to play the current audio-video continuously. According to the present invention, when the abnormal Bluetooth connection between the playing device and the sound source device is detected, the playing device is firstly connected with a network to download the network audio-video data corresponding to the current audio-video, and then the reception of the Bluetooth audio-video data sent by the sound source device is stopped, and the network audio-video data is switched to play, thereby improving the audio-video playing quality of the audio-video playing system, and preventing the audio-video playing from being interrupted.

Description

technical field [0001] The invention relates to the technical field of audio and video playback, and relates to a playback control method and device in an audio and video playback system. Background technique [0002] The audio and video playback system includes multiple playback devices, and the playback devices communicate through wireless private networks such as mesh (MESH) or point-to-point (Ad-hoc). Among them, one playback device in the audio and video playback system (the main playback device ) can establish a wired connection with the router (refer to Figure 1a ), the main playback device can also establish a wireless connection with the router (refer to Figure 1b ). Each playback device in the audio and video playback system is integrated with a Bluetooth module. The audio source device with Bluetooth function can be connected with the playback device via Bluetooth, and the audio and video data of the audio source device can be transmitted to the playback devic...
