Can someone explain this to me?

by G Fitz / February 27, 2007 12:07 PM PST

Many of BOL podcasts talk about IPTV, Streaming TV / Movies, and Tom's delayed Apple TV. The question I have always hade is this: Television and movies, especially HDTV, have problems being played over the internet secondary to large file sizes and current broadband limitations. If this is true, how do I get HDTV broadcasts thru my cable now? Does a broadcast show use smaller file sizes when being sent to me via my cable service rather than thru the 'tubes' of my broadband connection? There seems to be such a large discrepency. I watch LOST in HDTV every week instantly on comcast cable when I turn my TV on, yet, if I wanted to download the same episode from iTunes (at a much lower resolution), it takes some time to dowload. I understand that a cable broadcast is more of a stream than a download, but even the movie stream services, such as Netflix, are no where near the resolution or smooth play of good ol' regular TV. I cannot seem to make sense of the extreme diference.

Sorry to be so long winded,

Greg from Michigan.

Basically, compressed digital takes less bandwidth...

Thanks for the article link. I guess I was assuming the cable companies were not having trouble sending their HDTV content. Sounds like they're running out of bandwidth too.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
