Acceptable Bandwith for HDTV Component Video Switching? (1 Viewer)

[Doug_L]

Wondering how much bandwith a receiver needs in order to pass an HDTV signal without any degradation? Also, while we're at it, what's the necessary bandwith for DVD signal? I would assume that DVD is a lower number...

Friend looking to buy HK8000, which claims HDTV component video switching capability. I want to check and see if it can do it well. Different question, but does anybody know the HK's bandwith?

Thanks.

"System Bandwidth Requirements for Video:
NTSC Broadcast and VHS: * 4.2 MHz
Laser Disk: *5.3 MHz
Regular NTSC DVD: * 7 (6.8) MHz
Progressive Scan NTSC DVD and 480p DTV: * 13.5 MHz
1080i HDTV: *37 MHz; in practice with 22 MHz the picture is still very superb.
720p HDTV; *37 MHz. "
The H/K AVR 8000 has a component video bandwidth of 10Hz-30MHz (-3dB). This is from the owner's manual that you can download from their site.

I don't know the HK's bandwidth but here is a handy bandwidth calculator I just found:

Just noticed the second post. Sorry about that...

Without ANY degredation... 100 to 150 mhz.
