Abstract

Methods for generating or decoding an encoded audio bitstream including audio data and supplementary data (e.g., metadata and/or unrelated audio data), where at least some of the supplementary data is included as LSBs of audio segments, and/or at least some of the supplementary data is included in guard bands. Typical embodiments provide a scalable and video synchronous format compatible with real-time and file-based infrastructure components that support the SMPTE 337 format for carrying data in AES3 serial bitstreams, and/or provide a framework for extending distribution codecs to scale beyond an 8-channel limit to support multiples of 8 channels synchronously across multiple AES3 interfaces. Another aspect is an audio processing unit configured to perform any embodiment of the method or including a buffer memory storing at least one segment of an audio bitstream generated in accordance with any embodiment of the method.
