First-surface mirror - Normal mirrors have the silvering on the back surface of the glass. First surface mirrors have it on the front.
16 - 9 - Aspect ratio of widescreen DTV formats for all HDTV and some SDTV (Standard Definition) content, 16 unit width by to 9 unit height.
Analog Video - The conventional NTSC television system in use today uses analog technology, in which the image sound and the picture brightness and color are represented by signals proportional to these values. The values of these signals are vulnerable to interference and noise. Digital television overcomes this vulnerability and delivers signals that are totally clean.
OAR - (original aspect ratio) - Also called Letterbox format, OAR means that none of the image is clipped or squeezed. Unused parts of the screen are usually black.
Set-top box (STB) - A box, similar to the familiar cable box, that is capable of receiving, decoding and sending to the associated television the picture and sound of the selected DTV broadcast. The use of an STB would allow the use of conventional televisions to receive DTB programs, but at reduced levels of resolution and with imperfections due to aspect ratio differences, leading to letterboxing or cropping of the sides of the picture.
Compression - A method of reducing the number of bits required to store or transmit programs by the removal of redundant and/or non-critical information in the digital picture and sound. The DTV broadcasting standard for Canada, uses the MPEG-2 video and the AC-3 audio compression coding. Compression allows the delivery of more programs in a single channel.
AC-3 - The 5.1-channel compressed digital sound system specified for DTV broadcasting in Canada. AC-3 delivers CD-quality digital audio and provides five full-bandwidth channels for front left, front right, center, surround left and surround right speakers, plus an LFE (low frequency effect) subwoofer, for a total of 5.1 channels. AC-3 is one member of a family of sound systems developed by Dolby Labs.
