Aspect ratio: Aspect ratio refers to the

length to height ratio of TV. The ratio of a

standard TV is 4:3, while the ratio of a high-

de nition or wide TV is 16:9. The letter box

allows you to enjoy a picture with a wider

perspective on a standard 4:3 screen.

Bit Rate: The amount of data used to hold

a given length of music; measured in kilobits

per second, or kbps. Or, the speed at which

you record. Generally, the higher the bit

rate, or the higher the recording speed, the

better the sound quality. However, higher bit

rates use more space on a disc.
