The specifications that comprise basic Charter Communications HDTV are:

    * 720 or 1080 lines of resolution from both the channel broadcast and the HDTV monitor (Note: A 480i DVD is not high definition, even though the image quality is considerably higher than a standard definition TV broadcast on a standard defintion TV.)
    * Ability to display 16x9 aspect ratio pictures
    * Y Pb Pr video component connections from the cable receiver to the HDTV
    * Audio in the Dolby Digital (AC-3) format to support "5.1" surround sound

Lines of Resolution

charter communications High-definition TV displays pictures that contain significantly more detail, resulting in much 'crisper' pictures. Images viewed on TV screens are made up of small picture elements known as "pixels."

Each of these pixels is made up of three, closely spaced dots of color - red, blue and green. The pixels in HDTV sets are square, smaller, and spaced closer together than traditional TV, resulting in four to six times more visual detail than standard analog TV.

    Standard charter communications analog TV typically displays 480 lines of resolution (480i) with 720 pixels in each interlaced scan line. So, to determine total number of pixels displayed, multiply:

        * 480 scan lines x 720 pixels per line = 345,600 pixels displayed by standard analog TV.

    HDTV can display up to 1,080 lines of resolution (1080i) with 1,920 pixels in each interlaced scan line. So, to determine total number of pixels displayed, multiply:

        * 1,080 scan lines x 1,920 pixels per line = 2,073,600 pixels displayed by HDTV.

Aspect Ratio

Aspect ratio describes the relationship of a screen's width to its height. HDTV uses a widescreen format of 16:9 -- just like in a movie theater (by comparison, the aspect ratio on a standard TV set is 4:3). Which means your HDTV picture captures everything the filmmakers intended Charter Communications TV Listings
