Come On WDJT-DT...More Bandwidth!!!

[Matt Heebner]

Jim Hall...please start allocating more bandwidth to sports and other fast moving broadcasts...PLEASE! On every college football game I've watched, there is horrible pixelization on fast moving scenes. I know that this is not a national issue or there would be threads on AVS regarding this.
It is getting annoying, and personally I find it totally                    un-acceptable to present a HD sporting program in this manner.

I assume you're talking about today's Badger game...  I noticed that too... and it wasn't even  in HD.

I was  refering to the Alabama/Georgia game on this afternoon.  Every time the HD camera zoomed in on the action, it literally broke into the "blockiness" syndrome associated with starving bandwidth.

I really don't get it.  The digital transmission of 41 and 63 for the sole purpose of providing Time Warnier with their respective feeds makes no sense.  The cost of a optical feed is not that much and all the other stations have done it.  41 & 63 are availible on their respective OTA frequencies so there's no reason to duplicate there.  Somethime Weigel broadcasting does things that just don't make sense.

If WDJT-DT is broadcasting a college game in HD, don't they have to shut down the multi-programming of chs 41 & 63?  I always thought that DTV transmitters aren't designed to transmit both HD and Multi-programming modes at the sametime. Its either one or the other. Even thou I think its possible, but probably requires more bandwidth which is limited supposedly by FCC rules.

No actually they can define the amount of bandwidth allocated to each program stream. WDJT has been doing this all along...when a HD program comes they reduce the bandwidth allocated to 41 and 63 to provide as much as they can for the CBS program.  And if my understanding is correct they have set levels for regular programming versus sports, where they provide more bandwidth to sports.  But then again compared to Sat or Cable where they supply 20 Megabits to HD programming, you have to remember with the ATSC system the most you ever have is 6 MHz of bandwidth to do all of it.

Anyhow...I agree not very nice to look at.

[Matt Heebner]

Again with the horrible blockiness and a nice choppy audio signal. Thanks for yet another sub-par HD college football game WDJT-DT.

Actually both cable and off-air occupy the same 6 MHz bandwidth.  The difference is in the modulation scheme.  8-VSB used by terrestrial broadcasters gets you a little over 19 mb/s.  Cable's 256QAM is over 38.5 mb/s.

Just finished watching Florida v Arkansas on 58 and switched to ESPN HD for the Florida State v Virginia. What a contrast. The ESPN game is so much better it makes you wonder what in the world CBS is thinking. No motion artifact, not blockiness and the picture just jumps out at you. At least we have choices.
