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
The present invention relates to blueteeth network and bluetooth equipment, include but not limited to a kind of method of controlling playing volume of Bluetooth media of the bluetooth equipments such as bluetooth media player, bluetooth multimedia equipment.
Background technology
Bluetooth (bluetooth) technology is the open standard of wireless data and Tone Via, mainly solves short-range wireless connections, is generally 10 centimetres to 10 meters scope.A kind of function comparatively widely in the bluetooth applications, as shown in Figure 1, media player connects by bluetooth, uses the audio frequency and video output equipment to listen to the music, see a film; Use a teleswitch, connect by bluetooth, also can control the operations such as media player time-out, broadcast, F.F., rewind down.The former belongs to streaming media, and the latter belongs to the control of media play, respectively belongs to different protocol stacks in the Bluetooth protocol system.
When we when listening to the music or see a film, often need to regulate volume, the adjusting of volume is many-sided, we can directly regulate the output volume of bluetooth media player, also can regulate the volume of bluetooth audio frequency and video output equipment, can also finally regulate by blue Tooth remote controller the volume of bluetooth audio frequency and video output equipment.In the process of this volume adjusting, if do not keep certain order and rule, any one equipment all sends arbitrarily the order of volume control to miscellaneous equipment, the final unordered endless loop problem that only can cause volume control.
Summary of the invention
Technical problem solved by the invention is to provide a kind of method of controlling playing volume of Bluetooth media, to solve the unordered circulatory problems that volume controls between a plurality of bluetooth multimedia equipments in the prior art.
In order to address the above problem, the invention provides a kind of method of controlling playing volume of Bluetooth media, between bluetooth media player and bluetooth audio frequency and video output equipment, set up the streaming media link, it is characterized in that, may further comprise the steps:
(1) after described bluetooth media player sent voluntarily volume control command or receives the volume control command of blue Tooth remote controller transmission, described bluetooth media player was transmitted described volume control command to described bluetooth audio frequency and video output equipment;
(2) described bluetooth audio frequency and video output equipment is according to the volume of described volume control command adjustment output.
Method of the present invention, wherein, described volume control command is the audio frequency remote control command.
Method of the present invention, wherein, described working as between bluetooth media player and the bluetooth audio frequency and video output equipment, set up the streaming media link, and further comprise: described bluetooth media player and described blue Tooth remote controller are set up the signaling control link.
Wherein, described working as between bluetooth media player and the bluetooth audio frequency and video output equipment, set up the streaming media link, and also further comprise: relation has broken the wall of mistrust between described bluetooth media player and described bluetooth audio frequency and video output equipment and the blue Tooth remote controller.
Method of the present invention wherein, is adjusted the volume of output described in the step (2), be the volume that increases or reduce to export.
Compared with prior art, when the volume of bluetooth audio frequency and video output equipment changed, bluetooth audio frequency and video output equipment need not to send AVRCP (Audio/VideoRemote Control Profile) audio and video remote control command to the bluetooth media player by the method for the invention; When certain bluetooth multimedia equipment is received the AVRCP volume control command, it need not again loopback AVRCP volume control command, the method sends again the AVRCP volume control command to the bluetooth multimedia equipment after can avoiding the bluetooth media player to receive volume control command, thereby causes the Infinite loop problem of volume control command.

Fig. 1 is the structural representation that bluetooth media player of the present invention is connected with the bluetooth multimedia equipment;
Fig. 2 is the method flow diagram of the embodiment of the invention 1 described a kind of concrete control playing volume of Bluetooth media;
Fig. 3 is the method flow diagram of the embodiment of the invention 2 described a kind of concrete control playing volume of Bluetooth media.
Embodiment
The present invention provides a kind of method of controlling playing volume of Bluetooth media here, to solve the unordered circulatory problems that volume controls between a plurality of bluetooth multimedia equipments in the prior art.Below embodiment is described in detail, but not as a limitation of the invention.
Current use bluetooth equipment is listened to the music, seen a film is a important service in the bluetooth applications.Structural representation as shown in Figure 1 uses Bluetooth audio equipment to listen to the music and namely has the source device of audio frequency, and such as mobile phone, the output equipment to audio frequency is generally stereophone, transmits the stereo audio that high-quality coding is crossed.Bluetooth cellular phone can be used as the equipment that portable player is accepted control command simultaneously, blue Tooth remote controller is as the controller that sends order, as support the stereophone of Long-distance Control, user to use a teleswitch to control the broadcast of music on the mobile phone, stop, the operation such as F.F. retreats.When we wanted to regulate the volume of music, we can come order bluetooth media player to carry out volume adjusting by control link with described blue Tooth remote controller, also can directly control volume by the bluetooth media player.
Further specify the present invention below in conjunction with embodiment and accompanying drawing 2,3.
Embodiment 1, regulates in the flow chart of volume at the described bluetooth media player of Fig. 2, and described bluetooth media player and bluetooth audio frequency and video output equipment have been set up the relation of mutual trust, and by authentication, the method has mainly comprised following steps:
Embodiment 2, regulate in the flow chart of volume at the described blue Tooth remote controller of Fig. 3, set up the relation of mutual trust between described bluetooth media player and described bluetooth audio frequency and video output equipment and the blue Tooth remote controller, pass through authentication, and described bluetooth media player and described blue Tooth remote controller have been set up the signaling control link, and the method has mainly comprised following steps:
The standard that the above embodiment of the present invention 1 and 2 propositions are followed based on Bluetooth technology, consider the compatibility of various different bluetooth multimedia equipments, method as control volume between a kind of bluetooth media player and bluetooth audio frequency and video output equipment and the blue Tooth remote controller, avoid the unordered circulation controlled between a plurality of bluetooth multimedia equipments, improved preferably user's experience.
Certainly; the present invention also can have other various embodiments; in the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art can make according to the present invention various corresponding changes and distortion, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
