AB  - The A2DP Bluetooth protocol is used to transport stereo audio over a non-synchronous packetized structure. Using a frame-based codec, i.e., SBC or AAC, results in system latencies between 150 and 800 milliseconds with wide drifts up to +/– 200ms. A2DP can be used for music but because of the problems associated with the frame-based codecs, Bluetooth is not suitable for audio for video or gaming applications. The aptX codec offers an alternative. It uses a fundamentally different coding architecture and is sample-based delivering a system latency of 40ms with minimal drift, i.e., +/– 1 ms. With the use of aptX, Bluetooth can now be used to wireless connect TV’s to soundbars, gaming consoles to headsets, and PC’s to speakers.
