Subject: Erratum in RFC 3189

There are two errors in the SDP examples shown in RFC 3189:

1. In an fmtp paramter, there should not be a space after the colon.

2. The examples show the use of two fmtp parameters for a single
   payload type.  This was not necessary since they can be combined.
   In draft-ietf-mmusic-sdp-new-24.txt, section 6, the rules of RFC
   2327 are clarified to say that only one fmtp parameter is allowed
   per payload type.  Therefore, the examples should be reformatted to
   use a single line.

There are two places in the RFC where these errors appear.

In Section 3.1, the RFC says:

      a=fmtp:113 encode=SD-VCR/525-60
      a=fmtp:113 audio=none

It should say:

      a=fmtp:113 encode=SD-VCR/525-60 audio=none

In Section 3.2, the RFC says:

      a=fmtp: 112 encode=SD-VCR/525-60
      a=fmtp: 112 audio=bundled
      a=fmtp: 113 encode=306M/525-60
      a=fmtp: 113 audio=bundled

It should say:

      a=fmtp:112 encode=SD-VCR/525-60 audio=bundled
      a=fmtp:113 encode=306M/525-60 audio=bundled
