ABSTRACT:
A system and method allows a high-bandwidth serial or parallel digital video broadcast data signal to be monitored on a low-cost digital display device such as a computer monitor. The system includes means for extracting horizontal and vertical synchronization information and clock from the digital video broadcast data signal, and a transmitter converting the digital video data signal and the horizontal and vertical synchronization information and the clock into a Digital Visual Interface (DVI)-compliant digital video data signal. Beneficially, the system also includes: a color space converter converting the digital video broadcast data signal from a first color format to a second color format; a serial video data receiver receiving a serial digital video broadcast data signal and providing parallel non-return to zero inverted (NRZI) digital video data and a clock, synchronized to the parallel NRZI digital video data; an NRZI descrambler receiving the parallel NRZI digital video data and providing therefrom framed parallel digital video data; and a scan converter converting the digital video data signal into a digital video format suitable for display on the digital display device.
