ABSTRACT:
A method is provided for displaying data received as a composite video data stream, each frame of the composite data stream being composed of a field of data defining a first video display and a subsequent field defining a second video display. The composite video data stream is received and during first and third phases of a set of processing phases, the fields of data defining the first video display are stored in a first object buffer in memory. During second and fourth phases of the set of processing phases, the fields of data defining the second display are stored in a second object buffer in memory. During the first and third phases, the fields of data stored in the first object buffer are retrieved to generate the first display and during the second and fourth phases, the fields of data stoned in the second object buffer are retrieved to generate the second display.
