INTRODUCTION

A Brief Look at Terrestrial Television
Terrestrial broadcast is a traditional way of watching TV program, simply by installing an outdoor YAGI antenna or indoor
rabbit ear antenna, plugging it into the TV set's tuner, tuning channel, then you can enjoying watching the programs.
However, they are all so called "analog TV"
In recent years, "digital TV" arises and most countries' governments begin to mandate a Digital TV Transition from the old
analog TV broadcast system. Digital TV brings viewer greater entertainment in terms of not only a noise free High
Definition picture quality and Dolby AC-3 sound effect, but also the handy "EPG" (electronic program guide). 16:9 video
format gives a wider view of the same program compared with traditional 4:3 format. In the near future terrestrial data
broadcast will create a complete digitized world in every family. Many terrestrial TV broadcasts at this moment are
delivering digital TV programs, when the time of government mandated transition deadline comes, all the analog TV
transmissions have to give way to digital, which makes the Bravo series digital terrestrial HDTV receivers a wise investment
now.
Digital TV programs are broadcasted on both VHF and UHF radio frequency bands. Traditional analog TV transmission uses
one radio frequency channel for carrying one TV station's programs, in the digital TV transmission one radio frequency
channel can carry up to four more TV station's programs. For instance, the original analog channel CBS you used to watch
now may have become 2-1,2-2,2-3,2-4 when it's broadcasted in digital, here we call 2 as the major channel and -1, -2, -3 and
-4 are subchannel numbers. These four sub channels usually come from the same TV station and show four different
programs at the same time.
Digital TV signals are transmitted in either Free-to-Air (FTA) mode or Pay-per-View (PPV) mode. FTA signals can be
received for free by anyone with a MPEG 2 – DVB compliant digital terrestrial receiver, such of the Bravo series, Whereas
the PPV programs can only be received by paying an access fee to the broadcaster and using a Digital receiver incorporating
compatible conditional access system.
The BRAVO HD1 receiver allows you to watch both HDTV, EDTV and SDTV digital TV programs.
*HDTV stands for High Definition Television, its common video formats are "1920 x 1080 interlaced" or "1280 x 720
progressive".
*EDTV stands for Enhanced Definition Television, its common video format is "720 x 480 progressive)
*SDTV stands for Standard Definition Television, its common video format is "720 x 480 interlaced)
