SMPTE 302M – Television – Mapping of AES3 Data into MPEG-2 Transport Stream

1 Scope

1.1 This standard specifies the method of transporting AES3 data in an MPEG-2 transport stream fortelevision applications. For these television applications, the AES3 frame rate is 48 kHz.

1.2 Some applications may require linear PCM (pulse code modulated) digital audio in conjunction withcompressed video specified in the MPEG-2 4:2:2 profile. The MPEG audio standard defines compressedaudio, but does not define uncompressed audio for carriage in an MPEG-2 transport system. This standardaugments the MPEG standards to address the requirement to carry AES3 streams, which may consist oflinear PCM audio (at 48 ksample/s), or data carried within the AES3 format.
