Current speed?

3Mpbs... isn't that already possible with the new dsl/cable speed?

3 Gbps which is easily confusable with 3Mbps in some third world countries...

I think we all need that new Sisqo router that does 400 billion jiggabits.

With digital TV it's something else, we are talking of QUAMS, But 3Gbps is a lot. We can usually put few HDTV on a QUAM but a QUAM cannot handle this now. So basically, if you want to broadcast this you need to span the stream on few frequencies.

hmmm...ordinarily I'd agree with you. But based solely on what's written, "Sattilite" is caplitalized, so it must be a proper noun. , I still don't have a good idea what Sattilite is though. Presumably, it's some high bandwidth way of broadcasting HDTV. Or maybe they're a company that did that intentionally in order to distinguish themselves.

Actually it's QAM not QUAM. QAM stands for Quadrature Amplitude Modulation. In one 6 Mhz channel cable company using QAM-256 mode can send 38.8 Mbps of digital video/audio.

Digital video is compressed with MPEG-2 codec. An 1080i HD program can be compressed to a maximum of 19 Mbps (usually it's around 15-16 Mbps). Using QAM-256 mode 2-3 HD channels can be multiplexed. If you use MPEG-4 or WMV9 codecs bandwidth requerement is about 1/2-1/3 of MPEG-2.

1080p HD video if encoded using next generation codecs (MPEG-4) and transmitted using QAM-256 or QAM-1024 -- very doable.

Thing is that there is probably very little noticeable picture quality improvement. If it was like 4096p then of course by all means I want that. But the difference between 1080i and 1080p - is not really worth it.

Thanks for the info, maybe you can answer this one: I've heard that 1080i is use in movie industry when working on a movie, anything about that?

It would make sense to capture and render at the highest quality for a big budget film (at least to me). Once complete it can be easily down converted for film, DVD, streams, etc...

Most big budget films capture in "academy 2K", or basically 2048P. They might rough-cut with 1080i to make display on a TV easier, but generally on-line footage will be in '2K' image files. The data is stored on D1 tapes.

Funny Bio, because posting only to correct someone's spelling is something only as a$$ does. So I guess you're in good company.
