Scope

This document is applicable to fields such as wireless audio, streaming media, online television, and smart glasses. This document specifies the test methods for audio devices that support Bluetooth transmission of low-latency, low-complexity high-definition audio codecs. The test scenarios specified in this document mainly include playing music and video content through wireless devices to verify the interoperability between SRC devices and SNK devices that support the mandatory coding specifications and channel mode settings defined in T/CAIACN 013—2024. The Bluetooth transmission L2HC interoperability standard test specified in this document only checks the operation of L2HC and does not include a comprehensive function test of the Bluetooth transmission system. In addition, the relevant tests in this document only check the minimum operation of L2HC devices. Passing this test does not guarantee the complete and normal operation of all device functions.
