Native Format - Televisions have a fixed set of pixels or scan lines. That is their native resolution.

When this happens the program has to be converted to fit the native format of the television.

Noise Reduction - Refers to any of a variety of systems used to reduce background noise in analog audio signals. Dolby and dbx are two of the most well known noise reduction systems.

NR - Noise Reduction.

NTSC - National Television System Committee. U.S. government created organization which over 60 years ago defined the analog standard for broadcast television.

The NTSC is used primarily in North America and Japan.
