SMPTE 302M-2007

1 Scope

1.1 This standard specifies the method of transporting AES3 data in an MPEG-2 transport stream for television 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 with compressed video specified in the MPEG-2 4:2:2 profile. The MPEG audio standard defines compressed audio, but does not define uncompressed audio for carriage in an MPEG-2 transport system. This standard augments the MPEG standards to address the requirement to carry AES3 streams, which may consist of linear PCM audio (at 48 ksample/s), or data carried within the AES3 format.
