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
