The Codecs Parameter for "Bucket" Media Types
Draft of message to be sent after approval:
From: The IESG <email@example.com> To: IETF-Announce <firstname.lastname@example.org> Cc: Internet Architecture Board <email@example.com>, RFC Editor <firstname.lastname@example.org> Subject: Protocol Action: 'The Codecs Parameter for "Bucket" Media Types' to Proposed Standard The IESG has approved the following document: - 'The Codecs Parameter for "Bucket" Media Types ' <draft-gellens-mime-bucket-05.txt> as a Proposed Standard This document has been reviewed in the IETF but is not the product of an IETF Working Group. The IESG contact person is Allison Mankin. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-gellens-mime-bucket-05.txt
Technical Summary Several MIME type/subtype combinations exist which can contain different media formats (audio/3gpp, video/3gpp, and pending audio/3gpp2, video3gpp2). A receiving agent receiving these needs to examine the details of such media content to determine if the specific elements can be rendered given an available set of codecs. Especially when the end system has limited resources, or the connection to the end system has limited bandwidth, it would be helpful to be informed from the Content-Type alone if the content can be rendered. This document adds a new parameter, "codecs", to several type/subtype combinations to allow for unambiguous specification of the codecs indicated by the media formats contained within. Working Group Summary This is an independent submission, but it was reviewed for structure and overall content by the Audio Video Transport Working Group, and it received review comments on the IETF types mailing list. There were revisions of the draft for both reviews. The four week review of the document for IETF Last Call did not elicit further comments. Protocol Quality Allison Mankin was the IESG reviewer.
