Simulcast - The broadcast of the same program simultaneously over two or more different systems or channels, such as in HDTV and in NTSC. CRTC regulations require today that broadcasters simulcast much of their schedules.
Digital Cable - A service provided by many cable providers, digital cable offers viewers more channels. Contrary to many consumers' beliefs, digital cable is not the same as High-Definition Television or digital television; rather digital cable simply offers cable subscribers the options of paying for more services. Digital Monitor - DTV monitors are televisions that can display a digital signal but lack an integrated tuner (unlike an integrated digital set), and thus cannot receive a digital broadcast signal without an additional set-top box.
EDTV - Enhanced Definition Television. A term defining a television that displays the picture (either from SDTV or HDTV) at a resolution of 480p lines in either 4 - 3 or 16 - 9 aspect ratio and which includes Dolby Digital AC-3 multichannel sound.
A/D - Electronic device that connects an analog television signal to a digital system.
Comb filter - A circuit in NTSC sets that separates the color information from the brightness information.
SDTV - "Standard Definition Television." SDTV are based on 480 lines of vertical resolution and may have either 4 - 3 or 16 - 9 aspect ratios, and surround sound. Several SDTV programs are sent together to form the simulcast bundle. While SDTV pictures are of significantly better quality than NTSC, they are not up to the standard of HDTV.
Sub-channels - OTA DTV stations can show multiple programs simultaneously, subject to the 6 MHz bandwidth limit. This is called multicasting.
