Abstract:
A method of previewing video data on a field-by-field basis or frame-by-frame basis comprising the steps of:converting incoming encoded analog video data having timing, vertical and horizontal information into raw digitized video data, said raw digitized video data representing a plurality of discrete video images, including forming said raw digitized video data for each said discrete video image as a stream of digital samples taken while said incoming encoded analog video data is intact;storing at least a portion of each said stream of digital samples as a segment of said raw digitized video data in a memory, said memory performing data storage and transfer functions;converting a selected said segment of raw digitized video data that represents a discrete video image into outgoing analog video data; anddelivering said outgoing analog video data to a preview device for display;wherein said step of converting said selected segment of raw digitized video data into outgoing analog video data includes a step of adjusting timing data embedded within said selected segment of raw digitized video data, said timing data being a component of said raw digitized video data that is necessary for previewing.
