DICOM PS3.5 2024e - Data Structures and Encoding |
---|
This section describes the constraints pertaining to the presence of audio data alongside Pixel Data in DICOM objects. It affects the following Pixel Data encapsulation Transfer Syntaxes:
Any audio components present within a bit stream whose Transfer Syntax is among those listed above shall be interleaved in either LPCM, AC-3, AAC, MP3 or MPEG-1 Layer II audio format and shall comply with the following restrictions:
AC-3 is standardized in [ETSI TS 102 366]
If AC-3 is used for Audio components, the container format shall be MPEG-2 TS.
AAC is standardized in Part 7 of the MPEG-2 standard (see [ISO/IEC 13818-7], and Subpart 4 in Part 3 of the MPEG-4 standard (see [ISO/IEC 14496-3]).
CBR MPEG-1 LAYER III (MP3) Audio Standard
MPEG-1 Layer III is standardized in Part 3 of the MPEG-1 standard (see [ISO/IEC 11172-3]).
Although MPEG describes each channel as including up to 5 signals (e.g., for surround effects), it is recommended to limit each of the two channels to 2 signals each one (stereo).
MPEG-1 Layer II is standardized in Part 3 of the MPEG-1 standard (see [ISO/IEC 11172-3]).
