[0003] However, the maximum bandwidth of Bluetooth is only 1M, resulting in a limited transmission rate
And the wireless communication environment is relatively complex, the quality of the wireless environment in different frequency bands is different, and the transmission efficiency is different
Therefore, if a smart device is connected to multiple audio devices via Bluetooth at the same time, the amount of data will increase exponentially. Due to the limitation of the link bandwidth, the data may not be transmitted in time
If the data cannot be transmitted in time, the audio played by the Bluetooth-connected audio device will appear to be stuck or out of sync.

The present application discloses a display device and a Bluetooth audio transmission method, including: a Bluetooth module, where the Bluetooth module includes a plurality of links, each link can be configured as a target link for transmitting audio data to a Bluetooth audio device; a controller, The controller is configured to: monitor the transmission of audio data on each target link; if the transmission efficiency of the audio data on the first target link is low, increase the audio frequency on the first target link The amount of data compression; the first target link is any one of the target links. The display device and the Bluetooth audio transmission method provided by the present application monitor each target link used to transmit audio data to the Bluetooth audio device, and if the transmission efficiency in any target link is low, increase the audio frequency on the target link The amount of data compression to ensure that the target link transmits data normally, thereby ensuring that multiple audio devices connected to the display device at the same time play audio normally.
Description
technical field [0001] The present application relates to the field of display technology, and in particular, to a display device and a Bluetooth audio transmission method. Background technique [0002] At present, most smart devices allow only one audio device to play audio at the same time when connected to a Bluetooth audio device. However, with the development of smart devices, especially the rise of smart TVs, the popularity of Bluetooth devices has been further promoted. For example, Bluetooth audio devices such as Bluetooth headsets are used more and more. However, with the emergence of new scenarios such as simultaneous viewing by multiple people and stereo, Bluetooth multi-audio connection has become a new requirement. [0003] However, the maximum bandwidth of Bluetooth is only 1M, resulting in a limited transmission rate. In addition, the wireless communication environment is relatively complex, and the wireless environment quality of different frequency bands ...
