Marc.. this can't be the reason. The ATSC was developed specifically with multicasting in mind. Your engineering guys probably participated in some of the development of the specification. Your description of "signal" is also a little misleading. You are licenced to transmit bits on CH 20. One additional low bit stream dedicated to NW isn't going to impact the HD feed (most of the time)
Does your brand new encoder support adaptive rate encoding?
Are you already reserving some of the bitstream for other uses in the future? (descriptive video, SAP..)
Does your newsworld license from the CRTC exclude distributing newsworld OTA?
Your <6 year old audience would never notice the reduction in resolution on their total SD morning shows that run from 7 am till ??? Meanwhile you manage to run an insane total of 1 hour of morning news (from news world) on the HD network at 6am??? RC is a bit better with two hours 7-9am.
During the 2-3 hours of HD thats being delivered/week kill the NW feed. Its just a digital feed to the encoder right?
BTW Marc I really enjoy having you on line. I'm just suspecting there may be other issues beyond picture quality keeping NW, CP24 & NewsNET out of the respective OTA ATSC feeds of their parent networks.
