Bluetooth-based audio playing control method and remote control device

Abstract

The invention provides a Bluetooth-based audio playing control method which is applied to a remote control device. The method comprises the steps of establishing an HFP connection and / or PBAP connection with a host computer device; receiving an audio playing request; converting an audio file list which comprises at least one audio file to contact person information; and transmitting the contact person information to the host computer device. Through the Bluetooth-based audio playing control method, Bluetooth-based audio playing control can be better performed.

Description

technical field [0001] The present invention relates to audio playback control, and in particular to a bluetooth-based audio playback control method and a related device. Background technique [0002] Based on the advantages of low power consumption and little harm to the human body, Bluetooth technology has been widely used in various mobile devices and transmission equipment. When two Bluetooth devices establish a connection, they will detect the Bluetooth specifications supported by each other. Data can only be exchanged between devices if both parties have the same specifications. For example, Bluetooth defines the physical wireless connection between devices, and various Bluetooth specifications establish the commands and functions that these devices can use Bluetooth technology. [0003] When using Bluetooth to play audio files in electronic devices, Advanced Audio Distribution Profile (A2DP) and Audio / Video Remote Control Profile (Audio Video Remote Control Profile,...

Problems solved by technology

[0005] However, although most of the cars (such as old cars) are equipped with Bluetooth call function when they leave the factory, they do not support A2DP and AVRCP specifications, that is, they do not support stereo audio signal transmission, which makes the audio on the mobile phone Unable to play through the Bluetooth system of the car, greatly reducing the user experience

To allow a car stereo to wirelessly broadcast audio from a mobile phone, the entire bluetooth unit would have to be replaced, which would be extremely expensive

In addition, if the audio cable is used to connect the mobile phone to the audio source hole on the playback panel of the car, the user cannot operate the audio files through the playback panel, such as play, pause, next, previous Operations such as previous, volume up, volume down, and stop cause inconvenience in use

[0006] In addition, even though some in-vehicle systems have the function of reading USB, which can be used to play audio from the mobile phone, after connecting the USB, the mobile phone is used as a storage device, and the function will be limited

In addition, due to the current popularity of smart phones, it is common to use smart phones to navigate when driving a vehicle. If you use USB to play audio stored on the phone and use the phone to navigate at the same time, the audio is emitted by the car stereo. , the volume is high, but the navigation voice instructions are still sent from the mobile phone instead of the car stereo, and the volume is too low, which will reduce the user's mobile phone navigation experience, for example, the user may not be able to understand clearly because the audio is too loud Voice recognition for navigation
