[SIPForum-discussion] Question to SDP parameter profile-level-ID

[Cathleen.Ploetz at t-systems.com]

Hi,

I trying to understand the parameter profile-level-id and
sprop-parameter in SDP Protocoll.
Can anyone tell me, for what stand this parameter's? For example:

a=fmtp:96 profile-level-id=42801E; packetization-mode=1;
sprop-parameter-sets=J0KAFJWgUH5A,KM4DvID=;

I know:
a=fmtp:96  Payload
profile-level-id=42801E
42 Baseline and 1E is level 3.0

but for what stand 80?
What is sprop-parameter-sets=J0KAFJWgUH5A,KM4DvID= and how can I decode
the parameter?

Thanks

Cathleen
