The problem I notice is when the local stations switch from Network Dolby Digital encoded programming/spots to local insertion, that's where it just cranks. I have to grab the remote at all the breaks. Not sure how to fix that.

Most of the offenders are when it switches from a 5.1 surround sound show to a local, 2 channel only spot which is pushed out almost exclusively through the Center speaker. That's what we notice here.

[Jeremy Garchow]"Huh. Wonder what that will bring and where the clamp will take place.

It notes that NBC, for instance, has software that looks at the audio level of an incoming commercial and adjusts the gain before it goes into their distribution network. Seems like the most foolproof way: have every submitted tape analyzed to fit the station's desired dB output.

I hear that, Aaron. I'm just wondering if it's something that will be controlled by the broadcaster or if it's going to fall on our shoulders. We deliver a lot of spots to DG Fastchannel and we don't usually send tape! I agree, I think this will be a broadcaster responsibility.

Almost has to be. We deliver all our shows to their specs. So obviously if all the programming is playing at the same volumes, the content providers are doing their job. If the commercials are playing much louder than the programming, then the network is not doing its job during national spots and the local cable headend is not doing its job during the local spots.

More than that, it IS. Every broadcaster is responsible for the content that goes out over his or her airwaves -- there's no passing the buck. It's precisely the same situation as it would be running a spot with oversaturated colors.
To take a lot of the heat off local broadcasters, networks and syndicators establish technical standards for delivery.... and broadcasters can take a REactive stance by monitoring what goes out from these people, and taking steps to fix what's wrong later.
If it's all-local, then the broadcaster has to take a PROactive stance to make sure it's right before it airs.
And if the product's produced in-station and STILL wrong -- and airs that way -- the broadcaster should be barbecued.

Actually part of the problem is the insanely low dialog levels on cinema mixes in 5.1. Compared to tech specs for broadcast these levels may be 15-20 db lower than typical stereo programming.
They do this to allow for a wide dynamic range and tons of head room for big explosions. Apparent loudness is a very tricky thing to technically quantify, so it will not be easy to police.
Devices like the Dolby analysers also are fraught as they try to equate volume over time. A show with short sharp loud bits and then quiet will register as less loud that a show with a lot of regular but not excessive levels.
Seriously, I had a demo of this at AES and if the broadcasters get on board with systems like this, delivery specs for people like us will be much less... stringent. (Discovery people know what I'm talking about...)
