Abstract
An electronic apparatus, method, and algorithm achieve synchronization between video data executed on a video sink device and audio data executed on one or more Bluetooth audio sink devices. The electronic apparatus, method, and algorithm obtain calibration information for the one or more Bluetooth devices, determine a delay for outputting the video and audio data to the video sink device using the calibration information, control the Bluetooth transceiver to output the audio data to the one or more Bluetooth devices, and control the output circuit to output the video and audio data to the video sink device in accordance with the determined delay.
