Abstract

   Internet applications may reference specific codecs within the WAVE
   and AVI registries as follows:
   * video/vnd.avi; codec=XXX identifies a specific video codec (i.e.,
     XXX) within the AVI Registry.
   * audio/vnd.wave; codec=YYY identifies a specific audio codec
     (i.e., YYY) within the WAVE Registry.

   Appendix A and Appendix B provides an authoritative reference for the
   interpretation of the required "codec" parameter. That is, the
   current set of audio codecs that are registered within the WAVE
   Registry are enumerated in Appendix A. Appendix B enumerates the
   current set of video codecs that have been registered to date within
   the AVI Registry.

1 Introduction

   Internet-oriented multimedia applications reference multimedia
   content via predefined mechanisms (e.g., [2]). In the general case,
   this content was created primarily for the use of these Internet-
   oriented applications. Unfortunately, this Internet-oriented
   multimedia content represents a small minority of the total amount of
   multimedia content that has been created to date.

   For this reason, a growing interest is forming in establishing
   mechanisms by which the repertoire of multimedia content available to
   Internet-oriented applications(e.g., for RTSP [3]) may be greatly
   extended to include multimedia content that has been created outside
   of distinctly Internet contexts. For this to occur, a mechanism must

RFC 2361             WAVE and AVI Codec Registries             June 1998


   be created for Internet protocols (e.g., [1], [3], [4]) to be able to
   identify the codecs by which this so-called "traditional" multimedia
   content has been encoded.

   Unfortunately, several distinct encoding systems exist for
   traditional multimedia content. Each system has its own registry to
   ensure unique and stable codec identifications within that system.
   Perhaps the best known of these registries are Microsoft (for WAVE
   and AVI content) and Apple (for QuickTime content).

   The purpose of this paper is to establish a mechanism by which codecs
   registered within Microsoft's WAVE and AVI Registries may be
   referenced within the IANA Namespace by Internet applications.

2 References to Registries within the IANA Vendor Tree

   Reference [7] specifies that the IANA Namespace encompasses several
   trees. Discussions within the IETF-Types mailing list concluded that
   the most appropriate tree in which to reference codecs, which had
   already been registered by non-IANA Registries, is the Vendor Tree.

   As a result, the non-IANA registry is identified within the IANA
   Vendor tree by vnd.RegistryName. A specific codec, which has been
   registered within that registry, is identified by a required codec
   parameter as specified by Section 2.2.3 of [7].

3 WAVE and AVI Registries

   Both the WAVE and AVI Registries are historic databases that have
   been maintained by Microsoft as a free service. The Registries sought
   to assist developers of WAVE and AVI content and to standardize WAVE
   and AVI content by
   1) avoiding conflict and/or duplication with current definitions, and
   2) providing the registered information in a standard document and
      format that is publicly available.
   The historic nature of these databases implies that unless the
   original registrants informed the registrar of a change of status
   (e.g., company acquired, new contact, new location, new phone), the
   contact information has generally not been updated from the
   originally registered values.

   Audio codecs within the WAVE Registry are identified by WAVE Format
   IDs. The (audio) WAVE Format ID is officially known as "WAVE form
   Registration Number". The WAVE Format ID is a hexadecimal integer
   value. These codecs may be referenced within the IANA namespace as






Fleischman                   Informational                      [Page 2]

RFC 2361             WAVE and AVI Codec Registries             June 1998


   "audio/vnd.wave; codec=XXX", where XXX represents a valid WAVE Format
   ID (e.g., the WAVE Format ID of "123" is referenced within the IANA
   namespace by "audio/vnd.wave; codec=123").

   Video codecs within the AVI Registry are identified by AVI Codec IDs.
   The AVI Codec ID value is a FourCC encoding. A FourCC is 32-bits long
   and represents a (case-sensitive) four-character (i.e., ASCII) code
   value. These codecs may be referenced within the IANA namespace as
   "video/vnd.avi; codec=XXX", where XXX represents a valid AVI Codec ID
   (e.g., the WAVE Format ID of "SCRN" is referenced within the IANA
   namespace by "video/vnd.avi; codec=SCRN").

   Appendix A is an authoritative list of the complete set of audio
   codecs that have been registered (as of January 1998) within the WAVE
   Registry. Appendix B is an authoritative list of the complete set of
   video codecs that have been registered (as of January 1998) within
   the AVI registry.

4 Mapping Codec IDs to GUID Values

   Direct mappings exist between WAVE Format IDs and GUIDs and between
   FourCC codec values and GUIDs [5]. [Note: GUIDs are Globally Unique
   Identifiers that are also known as Universally Unique Identifiers
   (UUIDs). UUIDs have been standardized within the Open Software
   Foundation's (OSF) Distributed Computing Environment (DCE).] These
   mappings enable GUID-oriented software to directly refer to these
   historic codec values. For example, the Advanced Streaming Format
   (ASF) [6] uses GUID values to refer to codecs, and the following
   mechanism is used to convert the historic WAVE and AVI codec values
   into the appropriate GUID value for use within ASF.

   WAVE Format IDs are converted to GUIDs by inserting the hexadecimal
   value of the WAVE Format ID into the XXXXXXXX part of the following
   template: {XXXXXXXX-0000-0010-8000-00AA00389B71}. For example, a WAVE
   Format ID of 123 has the GUID value of {00000123-0000-0010-8000-
   00AA00389B71}.

   FourCC values are converted to GUIDs by inserting the FourCC value
   into the XXXXXXXX part of the same template: {XXXXXXXX-0000-0010-
   8000-00AA00389B71}. For example, a conversion of the FourCC value of
   "H260" would result in the GUID value of {30363248-0000-0010-8000-
   00AA00389B71}. [Note: the 32-bit FourCC value of "H260" is converted
   into hexadecimal 32-bit value (i.e., 30363248) because the initial
   XXXXXXXX of the GUID is defined as a DWORD and thus takes a 32-bit
   hexadecimal value. Endian considerations account for the apparent
   re-ordering of the original ASCII text.]

5  Security Considerations

   This document merely registers a set of formats. It does nothing to
   address the security considerations of these formats.  The format
   itself must be investigated for security issues with each format.
