What is variable aspect ratio?, What is HDMI?

What is variable aspect ratio?

The aspect ratio describes the relationship of screen width to screen height. Standard TV signals are based on an aspect ratio of 4:3 (four units wide by three units high). HDTV signals are based on an aspect ratio of 16:9, making the image 33 percent wider than a normal TV, and enabling you to view TV and movies as if you were watching them in a theater.

In addition, many DVD movies look better on the widescreen display, because most of the movies made in the last 50 years were filmed in an aspect ratio of either 1.85:1 (very close to 16:9, which is equal to 1.78:1) or 2.35:1 (even wider than 16:9).

Variable aspect ratio support enables the scaling of 4:3 and anamorphic video so that the image fills the screen.

What is HDMI?

High-Definition Multimedia Interface (HDMI) is the first industry-supported, uncompressed, all-digital audio/video interface. HDMI components can transmit both digital audio and digital video over a single cable, with improved quality over traditional analog connections because of an all-digital transmission. Transferring digital sources such as DVDs and HDTV programming, can now be accomplished without analog conversions that can degrade the original signal.
