PROFILE: H.263 profile number, in the range 0 through 10,
      specifying the supported H.263 annexes/subparts based on H.263
      annex X [H263X].  The annexes supported in each profile are listed
      in table X.1 of H.263 annex X.  If no profile or H.263 annex is
      specified than the stream is Baseline H.263 (profile 0 of H.263
      annex X).

So it says that if no profile or H.263 annex
Roni
