Full Description

This document describes the carriage of MPEG-4 AAC, HE AAC, HE AAC v2, and Extended HE-AAC (referred to collectively in this document as the "AAC family") profile audio in MPEG-2 transport systems. It also discusses MPEG-2 AAC LC profile audio, which is closely related to MPEG-4 AAC profile audio.

The descriptor necessary to signal AAC family audio and information for signaling mixing of main and associated services in the receiver are defined in this document. Multiplexing and transport for cable using MPEG-2 systems are defined in SCTE 54 [10]. Coding constraints for AAC family audio elementary streams are defined in SCTE 193-1 [1].
