The IESG has approved the following Internet-Drafts for publication as Proposed Standards: o RTP Payload Format for DV Format Video <draft-ietf-avt-dv-video-04.txt> o RTP Payload Format for 12-bit DAT, 20- and 24-bit Linear Sampled Audio <draft-ietf-avt-dv-audio-04.txt> These documents are the product of the Audio/Video Transport Working Group. The IESG contact persons are Allison Mankin and Scott Bradner. 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. Working Group Summary The working group supported advancement of these documents. Protocol Quality The documents were reviewed for the IESG by Allison Mankin.
