Broadcasters are simply stuffing as much crap on their transponders as they can instead of dedicating the necessary bandwidth to picture fidelity. DirecTV and HDNet are great examples. Good heavens, this looks like garbage. But we have how many home-shopping channels and pay-per-view channels?
The FCC's standards are a miserable failure. 18 picture formats? Broadcasters allowed to put multiple SD channels instead of HD in the spectrum they were given? No true resolution standards required to use the term "HD"? Interlacing? 29.97 frame rate? What year is this?
Quality is OVER, folks. All the equipment in the world isn't going to get you anything worth playing on it. It ISN'T getting better. That goes for sound too. New music and entire back catalogues are now being destroyed with dynamic compression to make it as "loud" as possible and 128 kbit data destruction as well. Generations of people will now grow up never having heard a good recording.
Enjoy everything you bought before the late '90s, 'cause that's it. - interiot, on 10/12/2007, -0/+0Product placement. The suggested solution is to purchase an Algolith Mosquito processor for $3,000. Okay, it's kind of cool tech, but hopefully there's a better/cheaper long-term solution. Hopefully MPEG-8 video (or whatever) will, when compressed, degrade in slightly less intrusive and obvious ways.
- mianos, on 10/12/2007, -0/+0oops discount that wrong story :(. OK I'm a fool.
This article on mpeg compression is pretty good all the same. - DNABeast, on 10/12/2007, -0/+0If you were going to read anything about image compression surely a professional in the industry would give the best write up. This article is a bit overwhelming but has heaps of interesting content. I digg it
- GmorG, on 10/12/2007, -0/+0Useless, There are better and free solutions for this problem
in avisynth
Deblock(quant=25)
BlindPP(quant=2,cpu2="ooooxx")
or just by putting video thurough ffdshow with SPP deblocking on.
of course those are poor mans ways. Though sample screens from article are very unimpressive. especially one with mosquito noise is easy to process for any filter. - inactive, on 10/12/2007, -0/+0granted that the article was written by a corp engineer - it's still cool work they've done and a good article (not exactly a viagra sales pitch). The real questions is when will the codec wars end - at some point the max compresion will be reached since we could never expect to see an entire movie summed up with "0101" - more bits will be required. I guess when we all have fiber who cares about compression?
- Guspaz, on 10/12/2007, -0/+0Very interesting. I don't think I've ever seen a realtime postprocessing filter that can do even remotely as good a job as this. Of course, this requires expensive discrete hardware, which explains why I haven't seen such a filter; it is beyond the realtime processing capabilities of a computer.
An interesting note, the company also makes a relatively cheap ($90) photoshop plugin that does this for still images (JPEGs). That could be very handy for cleaning up overcompressed JPEGs. They have a demo available on their site that you can download that allows previews but doesn't allow you to apply. - vtwin, on 10/12/2007, -0/+0I remember years ago when my cable company internally switched to a compressed signal. (I guess this happened at the satelite provider level) My cable TV signal was still analog, but I started to notice compression artifacts, and being good at spotting those, I got really annoyed with it. Most MPEG artifacts were blurred thanks to the limitations of the NTSC analog signal, but some programs were particulary affected. Cartoons were the first place I noticed it, fade transitions show obvious defects and blockyness.
I had a Sony (VHS) vcr, and it got problems with these artifacts for some reason. It kind of "amplified" the artifacts. Bright red things in particular, would get all blocky, and some kind of noise would appear on the blocky areas.
So I didn't get any actual improvement from the digital aspect, but rather the image degraded! We got screwed :) The problem with compression is that it can bring savings to companies that are disproportionate to the degradation of quality. For example a provider can chose to cut the size in half, and get 75% of the quality, knowing that they won't get twice as many complaints... I find that cell phone companies are particulary abusive in this regard and collide to keep the average audio quality low so that they can fit 10x more users in the same equipment. - GmorG, on 10/12/2007, -0/+0"I guess when we all have fiber who cares about compression?"
We will care about compression, think about super-duper Higher Definition resolutions future will bring. - boredzo, on 10/12/2007, -1/+0reported as spam because the person who wrote the article is a Product Manager at Algolith, and the article is little more than a sales flyer.
- scaaven2, on 10/12/2007, -2/+0front page with 35. what is going on today
- metalrock76, on 10/12/2007, -2/+0actually it was 25 when it went on the front page
- mianos, on 10/12/2007, -3/+0Virual marketing by MS? The hype seems to be growing to a frenzy. That video reeks of money. It's very slick production, although not my taste in style.
