Real test is Wheel of Fortune, since it is native 1080i, with the sparkling wheel.
ABC sports is 720p anyway so there should not be any degradation.

I didn't realize LWN was going to be run in 16x9 SD... interesting...

I appreciate the widescreen picture.

Well, we get to see more of a blurry picture compared to 4:3 plus it's taking little more away from 13-1...

It shouldn't take any extra bandwidth to do wide SD. The only difference is that the pixels are rectangular rather than square.

It's not being stretched...

I didn't say it was. I said the pixels are rectangular.

The video is 720x480i, which is 3:2. That translates to 13.5:9. That then is stretched to 16:9. The local station simply compensates for it at their end so when your display shows it at 16:9, it looks correct.

With FIOS I don't think I ve used OTA in over a year. There is just no need for the aggravation.

Isn't it funny how if you go back through this thread and see all of the engineers telling us that the commercials are on the same dB level as the shows.
Well, now they seem to finally be admitting that they are not.
Now Congress may get involved. I'm sure you all have seen the news stories about it.
Hate to say "We told you so"

I've heard that since my family bought their first tv in 1954. We've seen it on this forum for years. The bottom line is the broadcasters can control it but are spinless to require their "advertisers" to conform to a level standard. Given that most of the advertisers now in Hampton Roads are ambulance chasing screaming and lying lawyers are we to expect anything else. At least now they will be required to do it.

Technically speaking, the levels are the same. What's different is the amount of compression.

For example, in a piece of audio, if I'm shouting it you, it will be louder than if I'm whispering. That makes sense, and in the programming, that's how it is.

In the commercial, EVERYTHING IS COMPRESSED SO EVEN THE WHISPER IS AT THE SAME VOLUME AS THE SHOUT. Because the shout is rarer in the program, it makes the commercial seems louder, but is actually at the same volume as the loudest segment of the program which may only be a few seconds per show.

If I've understood correctly, this law mandates that commercials now need to be at the average volume, rather than peak volume, of the program.

I understand that and so do the broadcasters who willingly allow this practice. It is not rocket science to do what now apparently is going to be mandated. The problem is the broadcasters refusing to be responsible for the content bowing to the advertisers who will do anything ethical or unethical to sell their product.

It's not rocket science, but it is a complex problem that you are dismissing. Unlike most radio programming, TV requires different processing at different times. The compression of sitcom audio is probably pretty high while compression of movie or dramatic programming is likely very light. Predicting what the peak of an audio source will be is not too difficult, but predicting the average power level of a source is hard without having played it back at least once.

Consider, too, that cable and DBS operators insert their own commercials on every channel and now you have at least three places where audio is mixed before you hear it.

Don't forget about the 5.1 to 2 channel and vice versa level issues.
I think the ATSC standard could have bridged the gap between HD/SD and 5.1/Stereo much better, too late now.

It could have been and could be now if the broadcasters wanted to do it. Excuses are always available to provide the cover for inexcusable actions by those who are not being responsible.

It's funny that they will be able to do it now that it will be mandated. Face it the broadcasters will not stand up to the shyster lawyers hollering and screaming and the car dealers. Now thanks to congress they will have no choice and those caught violating the rules should have their broadcast license suspended for 30 days the first offense, 90 days the second and 12 months on the third and permanently on the forth.

You didn't take to heart what I wrote. Real-time audio processing technology works with the audio as it arrives, aiming to achieve the desired loudness while keeping peak levels within tolerance. For the most part, the audio sources mixed by a broadcaster will have some peak limiting and will generally already be near the same volumen. The "screaming lawyers and car dealers" spots have incredibly high average power (volume) due to the audio processing employed by the ads' producers. There's not much that can be done in real time to fix this, as the processing in the chain is set to squish dynamic range, not expand it.

Plus, most of the offending spots, I would wager, are NOT broadcast by the station but are inserted by the cable or DBS provider.

If the WTVZ representative reads this frequently, please take note that the TV Guide listings broadcast by 33-1 and 33-2 are swapped. I am not sure how long it has been this way but it would be nice if it was fixed.

The offending ones I see and hear are local commercials broadcast by the Hampton Roads stations like The Hammer screaming lawyer and Chesapeake Nisson.

The stations could stop it by refusing to run commercials that they can't control the audio levels on. It doesn't take a genius to realize the stations are scared to death of their advertisers power. The government will now hopefully force them to do what they should have been doing all along.

The problem I have experienced is when you are watching a program in 5.2 audio and the local commercial is in 2.0 audio. On my surround sound system, the 2.0 audio always seems to be louder.

An engineer in another Thread stated that AntennaTV will start sending out a promo loop on the network feed before its launch on 1/1/11. It's a guess that WTKR will also run this because it means AntennaTV will start its programming at midnight with no need for an engineer (to be) at the station to do any switching...

Anyone notice a problem with channel 10?
Every minute or so (usually less) I see a little skip in the picture. I have an HD DVR so I rewind it and slowly step through the frames and at the point of the skip I see a still frame out of order cadence. For example if I watch in slow motion a portion of the video that's fine I see 4 regular frames then 1 copy of the last frame. If I watch where it skipped in slow motion I see maybe 3 frames then a copy of the last frame. After that it goes back to 4 and 1 and it looks normal.
I thought it was a problem on Directv's side but then I also get the problem with it OTA too. Not happening on other local channels.

I hope this makes sense...

I agree but that didn't happen The broadcasters will have to address the issue now. Something they should have already done.

It's distracting... I also looked at WKTD/17 and even their analog channels (23, 35, 52) and all had the same "skipping."
