Embodiment 1

[0027] figure 2 This is a flowchart of a method for accessing an audio source device in an audio and video playback system provided in the first embodiment of the present invention. This embodiment is applicable to a situation where the playback device needs to be connected to the audio source device for audio and video playback in an audio and video playback system. It can be executed by the playback device, and specifically includes the following steps:

[0028] Step 101: The playback device in the audio and video playback system acquires the signal strength value of at least one interference signal source that is scanned.

[0029] The playback device may be any playback device in the playback group, and the playback group may include all playback devices in the audio and video playback system, or may include some playback devices. The playback device scans the signal strength of various interference signal sources in the surrounding environment in real time. The interference s...

[0040] image 3 This is a flowchart of a method for accessing an audio source device in an audio and video playback system provided in the second embodiment of the present invention. On the basis of the first embodiment, this embodiment provides a specific method for selecting and opening the playback device of the communication module. It includes the following steps:

[0041] Step 201: The playback device in the audio and video playback system acquires the scanned signal strength value of at least one interference signal source.

[0042] Step 202: The playback device sends the signal strength value to the main device of the audio and video playback system, so that the main device selects the lowest interference signal strength or the interference signal strength lower than the set value according to the signal strength value. Threshold the playback device and instruct the selected playback device to open the communication module.

[0043] Among them, the playback device sends the ...

[0048] Figure 4 This is a flowchart of a method for accessing an audio source device in an audio and video playback system provided in the third embodiment of the present invention. On the basis of the first embodiment, this embodiment provides a specific method for selecting and opening the playback device of the communication module. It includes the following steps:

[0049] Step 301: The playback device in the audio and video playback system obtains the scanned signal strength value of at least one interference signal source.

[0050] Step 302: The playback device sends the interference signal strength determined according to the signal strength value to the main device of the audio and video playback system, so that the main device selects the lowest interference signal strength or the interference signal according to the interference signal strength. The playback device whose signal strength is lower than the set threshold, and instruct the selected playback device to turn on...

Abstract

The invention discloses an access method and device of a sound source device in an audio / video playing system, and a playing device. The method comprises that the playing devices in the audio / video playing system obtain signal strength values of at least one scanned interference signal source; the playing devices with the maximum interference signal strength or with the interference signal strength lower than a set threshold value are determined according to the signal strength values; and the determined playing devices open communication modules, thus being connected with the sound source device. According to the scheme, the interferences borne by the playing devices and the accessing sound source device in the communication process are minimized.

Description

Technical field [0001] The embodiments of the present invention relate to communication technology, and in particular, to an access method, device, and playback device of an audio source device in an audio and video playback system. Background technique [0002] The audio and video playback system is composed of multiple playback devices, and each playback device interacts through a private network connection. When the audio and video playback system needs to play audio and video data synchronously, one of the playback devices and the audio source device are connected to obtain the audio and video data in the audio source device. At the same time, the playback device sends the acquired audio and video data to other playback devices through the private network to complete the synchronized playback of multiple playback devices in the audio and video playback system. [0003] In the prior art, the frequency band used by the playback device and the audio source device to communicate i...
