Description

SMPTE 2041-3 – Format for Non-PCM Audio and Data in AES-3 – MPEG-4 AAC and HE AAC Compressed Digital Audio in ADTS and LATM/LOAS Wrappers

This Standard specifies the method of packing MPEG-4 AAC and MPEG-4 HE AAC data rate reduced audio streams contained in either an ADTS or an LATM/LOAS wrapper into an AES3 transport stream. It also specifies the content of the data_type_dependent field of the burst_info (Pc) word of the Synchronization preamble used to signal the wrapper type and other necessary information about the payload. The Standard specifies the repetition rate, reference point, decoding latency and use of Pause data bursts in interrupted streams. This Standard supports the MPEG-4 AAC Profile, the MPEG-4 High Efficiency AAC Profile, and the MPEG-4 High Efficiency AAC v2 Profile. This Standard is limited to carriage of a single audio elementary stream.
