PURPOSE: An HD-SDI(High Definition-Serial Digital Interface) broadcasting digital monitor with optical signal input/output function and digital signal distribution function is provided to directly display an optical signal and convert the optical signal to an electric signal for the use in other equipments by adding an HD D-VDA(Digital Video Distribution Amp). CONSTITUTION: In an HD-SDI broadcasting digital monitor with optical signal input/output function and digital signal distribution function, a signal input via an electric signal input part(301) is sent to a selection part(306) via an equalizer(303), an optical signal input via an optical signal input part(302) is sent to the selection part after being converted into an electric signal via an O/E converter(305) after a photo diode(304), a signal selected by a user is sent to a plurality of HD-SDI output parts(309) via Re-Lock part(307) and an HD-SDI driver part(308), simultaneously being converted to an optical signal in a laser diode(311) to be output as an optical signal, a signal sent to a clock/data recovery part(313) is converted into a Y/C parallel data in a de-serializer(314), RGB parallel data in a color space converter(315), an analog signal in a DAC(316) to be applied to a CRT(318) via an AMP(317), and the CRT is supplied with an HV signal via a sync detection part(319) and an HV driver(320). |
