Embodiment 1

[0019] Example 1, in figure 2 In the flow chart of described bluetooth media player adjusting volume, described bluetooth media player and bluetooth audio and video output device have established the relation of mutual trust, by authentication, this method mainly includes the following steps:

[0020] Step 201, establishing a streaming media transmission link between the Bluetooth media player and the Bluetooth audio and video output device;

[0021] Step 202, the bluetooth media player sends an AVRCP remote volume control command to the bluetooth audio and video output device;

[0022] Step 203, after receiving the AVRCP remote volume control command, the Bluetooth audio and video output device increases or decreases the volume output according to the command instruction.

Embodiment 2

[0023] Example 2, in image 3 In the flow chart of adjusting the volume of the Bluetooth remote controller, the Bluetooth media player has established a mutual trust relationship with the Bluetooth audio and video output device and the Bluetooth remote controller, and the Bluetooth media player has passed the authentication, and the Bluetooth media player The player establishes a signaling control link with the Bluetooth remote controller, and the method mainly includes the following steps:

[0024] Step 301, establishing a streaming media transmission link between the Bluetooth media player and the Bluetooth audio and video output device;

[0025] Step 302, the Bluetooth remote controller sends an AVRCP remote volume control command to the Bluetooth media player;

[0026] Step 303, the bluetooth media player forwards the AVRCP remote volume control command to the bluetooth audio and video output device;

[0027] Step 304, after receiving the AVRCP remote volume control comm...

Abstract

The invention discloses a method for controlling the playing volume of Bluetooth medium. When a streaming media transmission link is established between a Bluetooth media player and a Bluetooth audio and video frequency output device, the method comprises that (1) after the Bluetooth media player automatically sends out volume control commands or receives the volume control commands transmitted by a Bluetooth remote controller, the Bluetooth media player transmits the volume control commands to the Bluetooth audio and video output device; (2) the Bluetooth audio and video output device adjusts the output volume according to the volume control commands. The method solves the problem of disorder circulation of volume control among a plurality of Bluetooth multimedia equipment in the prior art.

Description

technical field [0001] The invention relates to a bluetooth network and a bluetooth device, including but not limited to a method for controlling bluetooth media playback volume of bluetooth devices such as bluetooth media players and bluetooth multimedia devices. Background technique [0002] Bluetooth (bluetooth) technology is an open standard for wireless data and voice transmission. It mainly solves short-distance wireless connections, generally within the range of 10 cm to 10 meters. A function that is widely used in Bluetooth applications, such as figure 1 As shown, the media player is connected via Bluetooth, and audio and video output devices are used to listen to music and watch movies; using the remote control, connected via Bluetooth, can also control the media player to pause, play, fast forward, rewind and other operations. The former belongs to streaming media transmission, and the latter belongs to the control of media playback, and each belongs to a differen...
