Abstract
A method is provided for exchanging data between a user device and an audio output device over a wireless link. A user device detects that a trigger event for initializing a low latency mode has occurred at the user device, the low latency mode configured to cause the audio output device to reduce a size of a render buffer to be used for rendering audio data. In response to the detecting, the user device transmits an indication to the audio output device to initialize the low latency mode, the indication causing the audio output device to reduce the size of the render buffer to be used for rendering the audio data. The user device then transmits the audio data to the audio output device over the wireless link.
Claims24
A method for exchanging data between a user device and an audio output device over a wireless link, comprising:
- detecting that a trigger event for initializing a low latency mode has occurred at the user device, the low latency mode configured to cause the audio output device to reduce a size of a render buffer to be used for rendering audio data, wherein detecting the trigger event comprises:
- detecting that a power of signals received from the audio output device has exceeded a signal power threshold;
- and
- in response, determining that the user device is closer to the audio output device;
- transmitting, in response to the detecting that the power of signals received from the audio output device has exceeded the signal power threshold, an indication to the audio output device to initialize the low latency mode, the indication causing the audio output device to reduce the size of the render buffer to be used for rendering the audio data;
- and
- transmitting the audio data to the audio output device over the wireless link.
A computer-readable medium for exchanging data between a user device and an audio output device over a wireless link, the computer-readable medium storing instructions which when processed by at least one processor performs a method comprising:
- detecting that a trigger event for initializing a low latency mode has occurred at the user device, the low latency mode configured to cause the audio output device to reduce a size of a render buffer to be used for rendering audio data, wherein detecting the trigger event comprises:
- detecting that a power of signals received from the audio output device has exceeded a signal power threshold;
- and
- in response, determining that the user device is closer to the audio output device;
- transmitting, in response to the detecting that the power of signals received from the audio output device has exceeded the signal power threshold, an indication to the audio output device to initialize the low latency mode, the indication causing the audio output device to reduce the size of the render buffer to be used for rendering the audio data;
- and
- transmitting the audio data to the audio output device over the wireless link.
