Dear Inge,

Thanks for reviewing the RTP XS spec and finding the mistake in the “interlace” SDP parameter. You are correct and I have edited it to be “interlace” again (this was an unfortunate change by mistake that slipped in). It should be the same as with other RTP specs and more importantly, it should match with SMPTE ST 2110-20.

Best regards,
Tim.

Hi

I support advancing the document to Proposed Standard.

I have one comment/suggestion:

The name of the optional SDP parameter for signaling interlaced video, changed from “interlace” to “interlaced”, in version 07 of the draft. Reviewing other RFCs, I note that RFC 4175 for uncompressed video uses “interlace”, and RFC 5371 for JPEG 2000 video also uses “interlace”. Further, SMPTE ST 2110-20, which builds on RFC 4175, uses “interlace”.

In order to ensure a level of consistency, and make SDP parsing and generation nicer, could the editors please consider to use “interlace” as the parameter name?

Best regards,
 Inge Hillestad
