INFORMATION ON DIGITAL TELEVISIONDigital Picture FormatsDTV supports eighteen (18) Advanced Television Systems Committee (ATSC)" displayformats, which are variations of the four (4) following formats: 1080i (interlaced), 720p(progressive), 480p (progressive) and 480i (interlaced). The larger the number, thehigher the resolution of the picture.Interlaced ScanFor interlaced pictures, the odd number lines (picture information) are scanned,creating field 1, then the even number lines are scanned, creating field 2. The twofields are interlaced to provide the entire image (one frame). This process takes 1/30 tbof a second and is invisible to the human eye.Progressive ScanFor progressive pictures, all lines in an entire frame are scanned sequentially in 1/60 thof a second. With progressive scan, you will generally not see the thin black horizontalscan lines (venetian blind effect) associated with an interlaced picture.Digital AudioFor all HDTV formats, Dolby** Digital surround sound (also commonly referred to asAC-3** or DD 5.1) is the audio standard. AC-3 will provide CD-quality sound. Thesystem provides 3 separate audio channels for the front speakers (left, center, right), 2channels for the rear surround sound speakers, plus one channel for subwoofersound. You will need an external audio system capable of decoding the AC-3encoded sound to get the full surround sound effect. Otherwise, it can be connecteddirectly to your TV or audio system using only the stereo (left/right) audio outputs.Note: The stereo audio outputs are Dolby Surround compatible. You can connect a DolbySurround Pro Logic** decoder (not included) to the stereo audio outputs and receivesurround sound.*The ATSC is responsible for digital television development and standards.**Manufactured under license from Dolby Laboratories.
