Before Using
Digital broadcasting is the most advanced format of broadcasting, employing a new technology for
compression of audio and video signals which allows broadcasters to transmit digital signals using existing
terrestrial systems.
Due to this dramatic progress, new features of broadcasting service such as widescreen formats and higher
definition can provide a way to experience the full benefits of digital transmission.
High Definition Television (HDTV*) broadcasts can provide pictures twice as sharp as a conventional
broadcast and features sound encoded with Dolby® digital* 5.1 surround sound. When connected to a
receiver (sold separately) that features Dolby® digital decoding will provide a true theater experience in the
home.
Digital broadcasting has overcome problems experienced with analog television such as ghosting, "snowy"
pictures and interference. Digital television has a dramatic effect on these problems by its very nature.
In addition, the number of channels available has dramatically increased, so that you can make the best choice
among the variety of programs anytime with a clear picture.
The benefits extend not only to HDTV. It will also be possible to transmit multiple Standard Definition
Television (SDTV*) programs within the same bandwidth. Some data capacity could also be allocated to
provide more effective closed captioning or multiple language soundtracks.
Your current TV should be used for its entire service life.
