Technical Summary
The DV video document specifies the packetization scheme for encapsulating
the compressed digital video data streams commonly known as "DV" into
a payload format for the Real-Time Transport Protocol (RTP). There
are two kinds of DV, one for consumer use and the other for
professional. The original "DV" specification designed for consumer-
use digital VCRs is approved as the IEC 61834 standard set. The
specifications for professional DV are published as SMPTE 306M(D-7)
and 314M(D-9). Both are based on consumer DV. The RTP payload
format specified in this document supports IEC 61834 consumer DV and
professional SMPTE 306M and 314M(DV-Based) formats.
The DV audio document specifies the packetization scheme for encapsulating
the 12-bit nonlinear, 20-bit linear and 24-bit linear audio data
streams used in DV and DAT media into an RTP payload. The draft
also specifies the parameters regarding audio analog preemphasis,
which is often applied in this media, for use in an SDP announcement.
The treatment of preemphasized audio data specified this document
could be used in other audio formats such as L16.
