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

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. |

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...

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?

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. |

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.

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.
