From: The IESG To: IETF-Announce Message-Id: Date: Fri, 03 Feb 2006 10:01:37 -0500 Cc: avt chair , avt chair , Internet Architecture Board , avt mailing list , RFC Editor Subject: Protocol Action: 'RTP Payload Format for MIDI' to Proposed Standard The IESG has approved the following documents: - 'RTP Payload Format for MIDI ' as a Proposed Standard - 'An Implementation Guide for RTP MIDI ' as an Informational RFC These documents are products of the Audio/Video Transport Working Group. The IESG contact person is Allison Mankin. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-avt-rtp-midi-format-15.txt Technical Summary These documents define the RTP Payload format for MIDI (Musical Instrument Digital Interface), and additional guidelines on implementation specifically concerning the timing of reception and transmission for best performance in different applications. MIDI is a real-time media, which however is brittle to losses and errors. Therefore the RTP payload format defines recovery journals as a way of avoiding persistent audible errors, and discusses congestion control handling for these journals. The RTP payload for MIDI encodes the broad range of MIDI commands. The format is suitable for interactive applications (such as network musical performance) and content-delivery (such as file streaming). Working Group Summary There is consensus in the WG to publish these documents. Protocol Quality This RTP Payload format has been implemented during the development of the specification and successfully tested over an IP network between two remote sites, thus showing that the technical solution is successfully working. It has been reviewed by the MIDI Manufacturers Association and their comments have been addressed. Allison Mankin reviewed the document for the IESG, including a careful review with the editor of the media types, in parallel with ietf-types list review which raised no issues. Magnus Westerlund and Colin Perkins jointly shepherded these documents. Note to RFC Editor Expand MIDI in the abstract and introduction first appearances. Place the term MIDI before the expansion, because the standard usage in the community is no longer to provide the expansion. E.g. we strongly advise: MIDI (Musical Instrument Digital Interface) and not Musical Instrument Digital Interface (MIDI).
