This standard specifies the location and dimensions of the magnetic striping material applied to 16-mm motion-picture film, which is used for both picture and sound.

This standard specifies the spectral response of the photographic audio reproducer light source and receptor as a unit, including any optical filtering that can be interposed. The analog sound-track formats suitable for reproduction using such a reproducer include the cyan dye-only track (without redevelopment of silver) and both conventional and “high magenta” sound-tracks (with redevelopment of silver).

This standard specifies the position, dimensions, and reproducing speed of variable-area and variable-density photographic audio records on 35-mm motion-picture release prints.

This standard specifies data type specific format requirements for both AC-3 and E-AC-3 (“Enhanced AC-3”) data bursts carried within an AES3 interface according to SMPTE ST 337.

This standard specifies data type specific format requirements for caption data bursts carried within an AES3 interface according to SMPTE 337M.

This standard specifies data type specific format requirements for several types of data bursts that may be carried within an AES3 interface according to SMPTE ST 337. Included are descriptions of the data type (defined in SMPTE ST 338), the format of the burst_payload for the data type, the coding of data type dependent fields in the burst_preamble, and additional data burst and bitstream formatting requirements not defined in SMPTE ST 337. This includes specific synchronization methods which may affect formatting. — This standard covers generic data types which include null data, time stamp data, user defined data, pause data, and utility data which may include video frame synchronization information.

This standard specifies an interface format for the transport of non-PCM audio and data in professional applications using the AES3 serial digital audio interface. This standard includes both physical and logical specifications, based on the existing AES3 format, to allow exchange of non-PCM data between different devices. The standard accommodates multiple non-PCM audio and data formats and allows carriage of multiple data streams within a single interface. This standard provides means for carrying time code or time alignment information so that the information conveyed over this interface may be synchronized with information content delivered over other interfaces.

This standard specifies the audio channel assignment, and the relative levels of the audio channels, for recordings of audio programs containing six audio channels, onto storage media for film sound. Programs which are placed on media according to this standard are intended for reproduction in the cinema where the SW channel is always reproduced. This standard is not intended for application in the area of sound intended for reproduction in the domestic consumer environment.

(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.

SMPTE ST 299-2 defines an SMPTE 291M Type 1 packet structure for identifying audio channels numbered from 17 to 32, beyond the 16 channels defined in SMPTE ST 299-1. Four extended audio data packets and four extended audio control packets are identified. One of the extended audio control packets and one of the extended audio data packets is assigned to transport each of the four extended audio groups. Each extended audio group has four channels that carry up to four 24-bit audio channels with 32, 44.1, or 48-kHz sample rates, or up to two 24-bit audio channels with 96-kHz sample rate. The purpose of defining four extended audio groups is to allow for multiplexing up to 32 audio channels into the horizontal ancillary (HANC) data space of the video source image formats mapped to a 3 Gb/s Level A serial data interface. The 3 Gb/s Level B serial data interface is capable of carrying 32 audio channels via application of SMPTE ST 299-1 to each of two 1.5 Gb/s SDI channels. The format and location of audio data and control packets in the video data stream is identical to that of SMPTE ST 299-1, except for differences required to define extended audio groups.
