HD Broadcast Quality


What is the format (or formats) commonly used to deliver HD channels on cable?

I think I heard some time ago that ESPN uses a 1080i format, but Fox Sports uses 720i. I have no idea what the HD movies use.

Do different cable companies use different formats? I would guess that the format is a function of the content provider rather than the cable company, but I don't really know.

For what it is worth, I'm connected to CableOne in Idaho.

They are supposed to be using either 720p or 1080i. But, since most are compressed, no one really knows what resolution they are broadcasting at but rest assured, it is not the full 720p or 1080i resolution.

Re: HD Broadcast Quality


ESPN, ESPN 2, ABC and Fox all broadcast HD is 720p. The rest use 1080i. Like Joseph said, the exact resolution you get at your TV will vary depending on the delivery method.

Re: HD Broadcast Quality


Concerning resolutions etc...I understand that low compressed bandwidth..on ... SD and HD signals, keeps the image quality low...thus deeming the word HD meaningingless...

...my question is...does anyone know why high-bandwidth seems like such a pain in the a***@%$#! for broadcaster's to use?...instead of compressed?...face it...over ten years ago high bandwidth optical amplifiers where first being introduced to the world...now over ten years later...with high bandwidth sophisticated enough to be used more wide'ly...why is it so hard for broadcaster to send high bandwisdth signal for most channels?....I can see cost as a reason...and possibly not a big enough market for HD uncompressed signals etc...but couldn't they just push a button somewhere and crank up the juice so we can receive full uncompressed signals on all if not most cables channels?...if we asked for it?...or do they still need the recoucres to get to this level of broadcasting quality?...not to mention resoltion copyright laws etc...which is understandable...but if we pay for it then why shoudl be receive less?

It is ALL about greed!!!! Instead of broadcasting 100 stations, they try and broadcast 400. The extra 300+ stations generate advertising revenue, no matter what the video and audio quality is. They do not care about the latter, all they care about is how many minutes of adverstizing they can carry via more programing. To add even more stations, they reduce the resolution of all the stations, even HD, to fit more programming in. It is not a matter if they can do it technically, just not enough people who care or can tell the difference between standard definition and the crap they transmit. Of course their are no standards and no government enforcement so it is all open to misuse, even though it is all controlled by the FCC.

I have a few extra keyboards if you want one that doesn't have a sticky Period key. Or were you going for the Captian Kirk delivery?

A 1080p compatible display and some HD DVD and BlueRay players!!

Kind of like the difference between 480i standard definition programming and 480p DVD player performance.

Re: HD Broadcast Quality


AHH - I'm getting a Mitsubishi 1080p in 5 days and was wondering - reading Wikipedia it seems that a 1080i can be converted to a 1080p but in REAL life there is not much of a difference unless you are sitting close to the screen.

I'm still learning about HD and what it can really do!
