A value of 0 means that the Ancillary Data Flag (ADF) of the ANC data packet begins immediately following SAV. The horizontal offset from SAV is measured in terms of 10-bit words of the indicated data stream and data channel. For line number, I see your point. Really no point in referencing anything= even for SD, how about just: Line_Number: 11 bits This field contains the digital interface line number that corresponds to the location of the ANC data packet as an unsigned integer in network byte order. -Thomas On 1/4/18, 4:21 AM, "John Fletcher" wrote: That is better but there is still the issue that no definition is given= for UHD.

I also have a slight issue with the Line_Number definition because it s= ays line number for HD is defined in ITU-R BT.1120 but that does not cover = 3G Level A or HFR. So I would suggest changing the first paragraph to: "This field contains the line number (as defined in ITU-R BT.1700 [BT17= 00] for SD video or the appropriate interface mapping specification for HD = or UHD video) that corresponds to the location of the ANC data packet in an= SDI raster as an unsigned integer in network byte order." I would also move the paragraph beginning "In multi-stream interfaces .= .." so that it follows the first paragraph. And finally, in the "Note ..." paragraph, I would change "sample struct= ure specification" to "interface mapping specification".

This draft is a work item of the Audio/Video Transport Payloads WG of the IETF. Title : RTP Payload Format for VC-2 HQ Profile Video Author : James P. Weaver Filename : draft-ietf-payload-rtp-vc2hq-04.txt Pages : 21 Date : 2018-01-08 Abstract: This memo describes an RTP Payload format for the High Quality (HQ) profile of SMPTE Standard ST 2042-1 known as VC-2. This document describes the transport of HQ Profile VC-2 in RTP packets and has applications for low-complexity, high-bandwidth streaming of both lossless and lossy compressed video. The HQ profile of VC-2 is intended for low latency video compression (with latency potentially on the order of lines of video) at high data rates (with compression ratios on the order of 2:1 or 4:1). The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-payload-rtp-vc2hq/ There are also htmlized versions available at: https://tools.ietf.org/html/draft-ietf-payload-rtp-vc2hq-04 https://datatracker.ietf.org/doc/html/draft-ietf-payload-rtp-vc2hq-04 A diff from the previous version is available at: https://www.ietf.org/rfcdiff?url2=draft-ietf-payload-rtp-vc2hq-04 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

This draft is a work item of the Audio/Video Transport Payloads WG of the IETF. Title : RTP Payload for SMPTE ST 291-1 Ancillary Data Author : Thomas G. Edwards Filename : draft-ietf-payload-rtp-ancillary-14.txt Pages : 19 Date : 2018-01-11 Abstract: This memo describes a real-time transport protocol (RTP) payload format for the Society of Motion Picture and Television Engineers (SMPTE) Ancillary data, as defined by SMPTE ST 291-1. SMPTE Ancillary data is generally used along with professional video formats to carry a range of ancillary data types, including time code, Closed Captioning, and the Active Format Description (AFD). The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-payload-rtp-ancillary/ There are also htmlized versions available at: https://tools.ietf.org/html/draft-ietf-payload-rtp-ancillary-14 https://datatracker.ietf.org/doc/html/draft-ietf-payload-rtp-ancillary-14 A diff from the previous version is available at: https://www.ietf.org/rfcdiff?url2=draft-ietf-payload-rtp-ancillary-14 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

The payload format is designed to be able to interoperate with existing TETRA transport formats on non-IP networks. ..." from chapter 3 "Media Format Background" "The TETRA codec is used as vocoder for TETRA systems. The TETRA codec is designed for compressing 30ms of audio speech data into 137 bits. The TETRA codec is designed in such a way that on the air interface two of these 30ms samples are transported together (sub- block 1 and sub-block 2). ..." Main motivation of this payload is to attach ground based applications (fix= ed terminal stations, control room applications) to TETRA networks. Those n= etworks are still TDM based while ground based applications today are conne= cted via IP. As typically control rooms consume a bunch of so called "TETRA= talkgroups", it makes sense to use TETRA encoded audio (as it is realized = as an ACELP encoder) to save high value quality of service bandwidth (8kBit= /s net data rate rather than e.g. 64kBit/s with G.711) without any drawback= in terms of decreased audio quality and _without_ any transcoding. TETRA c= odec anyhow is used as the one and only codec within the entire TETRA netwo= rk (both the air as well as the ground infrastructure). BTW: TETRA is still far away from being dead, it is still widely used and s= till expanded at authorities and civil services. So I warmly invite you to review and give me your +1 on this draft that it = can become an RFC sooner or later. Many thanks Andreas ---------------------------- Dipl. Ing.

Hi James

Besides the editorial changes,= you added significant amount of new text (section 4.4 and and VC-2 version= ing). I feel like a new WGLC is due here. I will start a short WGLC so ever= ybody has a chance to look at the changes. Then, we can ship it to the AD i= f all is well.
