HIGH DEFINITION TELEVISION
SD / HD DTV FORMATS
SD - STANDARD DEFINITION DTV
480i - 480 LINES INTERLACED
480p - 480 LINES PROGRESSIVE
SD FORMAT IS MUCH LIKE YOUR ANALOG TV SIGNAL EXCEPT IT IS DIGITAL. IT IS COMPARABLE TO A PROGRESSIVE SCAN DVD PICTURE. IT CAN BE BROADCASTED IN FULL WIDE SCREEN 16:9 AND 4:2 VIDEO FORMATS. AUDIO IS FULL STEREO/MONO/DOLBY DIGITAL SURROUND 2.O.
HD - HIGH DEFINITION DTV
1080i - 1080 LINES INTERLACED - BEST HD!
720p - 720 LINES PROGRESSIVE
1080i IS THE VERY BEST HD FORMAT CURRENTLY AVAILABLE TO VIEW. WATCHING 1080i IS ALMOST LIKE YOU ARE THERE ESPECIALLY IF YOU HAVE 5.1 DOLBY DIGITAL SURROUND SOUND. 1080i AND 720p BOTH ARE IN WIDE SCREEN 16:9 FORMAT AND IN 5.1 DOLBY DIGITAL SURROUND SOUND. 720p IS A GREAT FORMAT. NOT QUITE AS IMPRESSIVE AS 1080i BUT STILL VERY NICE VIDEO QUALITY. I PERSONALLY CANNOT TELL THE DIFFERENCE HALF THE TIME. 1080i AND 5.1 DDS IS QUITE A VISUAL AND AUDIO TREAT FOR THE EYES AND EARS.
NOTE: A COOL THING ABOUT DTV IS THAT DTV STATIONS CAN MULTICAST MULTIPLE CHANNELS AT A TIME OFF ONE TRANSMITTER. HOWEVER WITH HD YOU CANNOT REALLY BROADCAST MORE THAN 3 CHANNELS AT ONCE (BANDWIDTH), BUT WITH SD YOU CAN BROADCAST UP TO 6 CHANNELS AT ONCE! WITH DTV YOU CAN FIT 7 DTV CHANNELS WHEN ON ONLY 1 ANALOG CHANNEL.
