Simulcast is defined to take bundle into account. It relies on the use of RID  or PT identification, but simulcast scope is per definition local to the surrounding “m=” line and simulcast extends the identification space by adding bundle MID identification in case of bundling. Therefore, it is not affected by multiplexing, meaning NORMAL.

Hi,

...

>I think that RID is not affected my multiplexing and the category must be NORMAL.

I agree that RID is probably NORMAL.

Regarding the ‘simulcast’ attribute, it would be nice to get some input from the simulcast folks.

If you have bundled multiple media, assuming it is ok to simulcast only parts of that media? If so, I guess the category would be NORMAL.

Regards,

Christer
