METHOD AND APPARATUS FOR CARRYING DIGITAL DATA AS ANALOG VIDEO

摘要

An interface, e.g., a modem-like interface for converting a digital information signal into an analog signal for use within an analog television studio infrastructure. Namely, the present invention employs a novel modulator (210) that conveys compressed video data into analog video lines by creating an analog "video" signal that contains video gray-scale levels which correspond to digital data values, instead of containing an image.
