To bring both HD and SD feeds would require (6) 90+mile microwave paths. Not to mention we only have so much bandwidth to utilize; to deliver both would cut the HD quality by a third.
Forgiving for the moment that SD takes up less bandwidth and that in essense doing a full SD feed on the path would be an increase from three HD microwave paths to the bandwidth of four HD microwave paths, can't some local switching be done?
It appears the station is taking the one HD feed for each station and downconverting and cropping it for OTA NTSC broadcast (and for SD feeds to cable/satellite). Apparently the decision has been made that it is better for the majority of your viewers (those with SD setups) to lose 25% of the picture. A second downconverter set on letterbox with a switch between the two converters or simple control of the one your station has (if possible) would provide a BETTER SD signal for the market. We've got two more years of SD ... don't give up on NTSC viewers!
I'm fortunate that I can get a distant CW signal (superstation) and see the whole feed. No one can get a distant ABC feed so the 25% crop imposed on them cannot be easily fixed (without a decent antenna for WOTV, WPTA or WLS). There has to be a better way of serving the market than this.
Even after CW25 and (ABC57) goes HD on the companion channels SD quality will remain an issue.
Thanks again for your time.
