How do I know if a recording is in the MPEG 2 vs the MPEG 4 format?

 

[EMoMoney]

So far, only Mp4 recordings are the HD locals. Everything else is Mp2 to my knowledge.

101,110, and 119 are MPEG2. 99 and 103 are MPEG4. So right now local HD and RSN HD from the 99 or 103 Satellite are MPEG4. All others are MPEG2.

So is there a way to figure out what channels besides my local HD's are MPEG 4?

ONLY local HD channels are Mpeg4 at the present. No others are being transmitted in Mpeg4.

I thought cyber said thr Regional Sports Netwoks were MPEG 4?

Sorry..............i omitted those.

 

[mocciat]

So there's only like 6 MPEG 4 channels?

Yes, depending on the market. By the end of 2007 DirecTV has the potential to have up to 150 national HD channels in addition to 94 percent of locals in HD.

Those would be on Ch 96 or 97. The RSN broadcasts on Ch 95 are MPEG2.

Aren't the HD RSN's up in the 600's MPEG 4 also?

Yes, they are.

Here's the way I figure it... If you can't tell the difference, what difference does it make?

Just having the knowledge is the difference. If we can't tell they why is D* wasting time and money to roll out MPEG 4. Not to mention I read all these problems with MPEG 4 playback and was wondering how everyone knew that they problems are actually with the MPEG 4's. I couldn't tell the difference but I think you would agree that knowing which was which would be nice.

Because MPEG4 is the future if D* wants to add more HD channels, locals or nationals. It allows for substantially higher compression for the same signal quality or more channels at the same bitrates as MPEG2. The way everyone knows they're having problems with MPEG4 is that most of those having serious problems have been with HD locals, in other words, MPEG4 HD channels.

Mocciat,

Can I tell the difference? Not really.
Is there a difference? YES.

DTV is spending the time and money to roll out MPEG-4 because it's a more efficient use of bandwidth. Think of it this way... Your DVR can record MORE MPEG-4 HD content because the amount of bandwidth and file size is less with MPEG-4.

I believe (correct me if I'm wrong) all HD locals (except LA and NY) are MPEG-4. All other HD content on DTV is MPEG-2. That's how folks are determining whether they are having problems with MPEG-2 and MPEG-4.

BTW: Sorry if my original post sounded curt, I was actually trying to be funny. :hurah:

 

[PoitNarf]

Give it another year and you won't need to ask this question any longer. It will probably be all MPEG4 by then.

What is Dish Network doing in this area?

Is MPEG-4 the same as HD Lite? I want to get my terminology right.

DN is going MPEG4 as well from what I've read.

Also (from what I've read), the MPEG4 channels don't really carry the same HD Lite designation as the MPEG2 HD channels. For the MPEG2s, D* is watering down the resolution from 1920x1080 to 1280x1080 and then displaying it again on your TV as 1920x1080. This is not the case with the MPEG4 channels. There is a reduction in bitrate and other things, but they aren't messing around with the resolutions on the MPEG4 channels. This is all from other posts I have read. I am by no means an expert in this area.

Not sure what E* is doing, but HD Lite is a generic term used to refer to any HD transmission system that involves "downrezzing" the original signal, usually for bandwidth reasons. It can be done with any system of encoding/decoding if the provider chooses.

Both D* and E* suffer from accusations of "HD Lite."
