No, they are different things.
NTSC is the color encoding process used in North America for standard definition video signals. In Europe, a similar encoding system called PAL is used for standard definition video.
HD video is never encoded into a single signal and therefore neither NTSC nor PAL play any part in the transmission of any HD signal.
NTSC and PAL are two types of color encoding. NTSC is used in North America while PAL is used in Europe. Most other countries around the world use one or other. HD signals do not use PAL or NTSC color encoding and most televisions are capable of displaying HD content whether source in the US or Europe. However, many disc players and games consoles use region coding to prevent a disc bought in one region (USA for example) being played in another (UK for example). This is normally a function of the disc player or games console rather than the televsion.
You will need a decoder, is the easiest answer; NTSC is mainly in the US / Canada, while PAL is in Europe and many other countries. Both are analog systems.
A standard NTSC Roxio Game Capture HD will not work with an English TV as they operate on a different frequency. It is possible to purchase a compatible model in the UK or to use a similar model.
To receive Broadcast Television Signals of NTSC Analog or ATSC Digital a television antenna is needed. If the TV has ATSC built in , then a converter box will not be needed.
Yes, it will as long as your TV is NTSC compatible. If it is not, there is and NTSC-PAL adapter available which will allow this to work on older TV which are not compatible with NTSC
No.
Broadcast TV will be changed to all digital in 2009 so TVs won't work without an adapter. HD and big screens seem to make little sense without cable or satellite. I suggest getting a used TV for now from Freecycle.org. People are just throwing out TVs to switch to HD's. Search " NTSC 2009 TV FCC "
HD DVDS are DVDs that can be played on high definition TV players. The regular DVD can be played on any TV and is not in the same definition as the HD DVDs.
No, but if you wont the HD quality and you wont to watch the T.V at the same time you will, otherwise you'll have to do without watching the T.V. But the HD PVR can record in SD as well.
NTSC stands for National Television Systems Committee. It's the set of standards used for TV and video in the U.S. since 1953. These are mandated standards for televisions sold in the U.S and some other countrys like Japan. They include an aspect ratio of 4:3, 525 horizontal interlaced scan lines, and 29.97 fps (frames per second). Since NTSC allows the control of the HUE (tint) of the color unlike PAL that does not, many TV engineers used to say that NTSC stood for "Never Twice Same Color"
the same old stupid screen
A TV with basic cable will not have the same quality as a TV with a HD box. HD stands for high definition and improves the sharpness and clearness of the program.
