Introduction to the Type D-10 and D-11 Formats

The specification for the type D-10 format is defined by a suite of SMPTE standards The type D-10 uses MPEG-2 422P@ML video compression constrained to operate with intra-frame coding operating at data rates of 30, 40 and 50 Mbps. The audio recording offers four channels at 24-bit resolution or eight channels at 16-bit resolution. The type D-10 format is defined by two SMPTE standards:

• SMPTE 356M for the MPEG video compression and

• SMPTE 365M for the VTR format.

A recommended practice, SMPTE RP204 specifies an encoder template for the type D-10 format as comprising one MPEG-2 422P@ML video essence element, one 8-channel AES3 audio essence element, and one data essence element.

In addition, the type D-10 format uses the SDTI-CP data interface specified using the following two standards:

• SMPTE 326M for the SDTI-CP and

• SMPTE 331M for the SDTI-CP essence and metadata element definitions.

Again, SMPTE RP204 applies.

The specifications for the type D-11 format define a high definition VTR that records compressed pictures using 1920*1080 picture sources and four AES3 audio channels each at 24 bits/channel. type D-11 is...
