1 edit | Re: Our way or the highway said by MxxCon  :The problem with such rule is there is no standard measurable unit of image "quality" Not true.
There are ITU and MPEG standards for making objective measurements that correlate to perceived image quality.
And as for other "HDTV standards", there are whole volumes of ATSC and MPEG standards for modulation, coding, and transmission of HDTV signals.
The title of this article is the problem. There are plenty of HDTV standards, including those for objective quality measurement.
What there aren't any of are HDTV quality regulations. There's no law that that states what image quality providers must broadbast, other than an ambiguous one that says at least one prgram equivalent to NTSC quality must be provided.
Broadcasters, cable MSO's, and DBS providers believe most consumers don't know and don't care about pciture quality. They're probably right; how many TV's are horribly misadjusted? Most of them. The providers believe they'll be more profitable providing quantity over quality. So they pack in as many overcompressed channels as they can.
The one place you may get relief from this is Blu-Ray. There is no economic incentive to compress more than what is necessary to fit on the disk. And the folks controlling the compression are the same who produced the film, and have an interest in having its quality preserved and displayed. |
