Calrad HDTV rated cable or equivalent cable must be used for the proper delivery of HDTV signals for distances up to several hundred ft. to Drive Plasma, LCD, DLPmonitors for multiple display applications. The 40-93 B has the ability to distribute 4 outputs of (Component Video,Y, Pb, Pr)+ analog stereo audio or 3 Composite Video signals and stereo analog audio or 3 Digital audio and stereo analog audio. High frequency, fast slew rate op-amps with 75 ohm termination circuitry provides low noise and distortion free video 3 without any appreciable signal degradation. High quality connectors for repeat removal and insertion of cables, will provide many years of trouble free operation. The 40-933B unit may be used free standing or mounted horizontally, or vertically on a wall using the 4 mounting holes. Visual indication the unit is on by a front panel red L.E.D indicator. Composite video is the format of an analog television (picture only) signal before it is combined with a sound signal and modulated onto an RF carrier. Composite video is often designated by the CVBS acronym, meaning any of "Color, Video, Blank and Sync", "Composite Video Baseband Signal", "Composite Video Burst Signal", or "Composite Video with Burst and Sync". It is usually in a standard format such as NTSC, PAL, or SECAM. It is a composite of three source signals called Y, U and V (together referred to as YUV) with sync pulses. Y represents the brightness or luminance of the picture and includes synchronizing pulses, so that by itself it could be displayed as a monochrome picture. U and V represent hue and saturation or chrominance, between them they carry the color information. They are first mixed with two orthogonal phases of a color carrier signal to form a signal called the chrominance. Y and UV are then combined. Since Y is a baseband signal and UV has been mixed with a carrier, this addition is equivalent to frequency-division multiplexing. High-definition television (or HDTV) is a digital television broadcasting system with higher resolution than traditional television systems (standard-definition TV, or SDTV). HDTV is digitally broadcast; the earliest implementations used analog broadcasting, but today digital television (DTV) signals are used, requiring less bandwidth due to digital video compression.
