HD-TV: Connectivity
If you've decided to change DVD players or invest in the Faroudja 720P scaler of your dreams, all you need to do is plug in your TV.
DVI, a well-known interface for PC users, can transfer high-resolution images. DVI is also an opportunity for manufacturers to implement physical anti-copy measures. That means that it might be impossible to connect a DVI DVD player to a computer monitor, since the monitor might not be recognized as an authorized peripheral.
YUV is also a way of transferring HD format in analog.
The HDMI connector found on certain models is a development of DVI that's suited to audio-video. In addition to transmitting video in digital using the same principle as DVI - in fact, DVI-to-HDMI adapters exist - HDMI can also carry up to 8 channels of digital audio. However, some older implementations of HDMI on TV sets don't make full use of that potential, so manufacturers often install HDMI with only two audio channels.
