摘要： The present invention includes a parallel video format to field sequential video format conversion method wherein multiple analog signals that represent the magnitude of a set of colors that are components of the colors of a video display are converted to a set of digital video codes. This set of video codes buffered and rearranged to align with an input bus. The input bus is operably connected to a bus-exchange means which is operably coupled to a pair of Input/Output busses of two sets of dynamic random access memories. The Digital Video Codes are stored in sequence in the set of dynamic random access memories selected by the bus-exchange circuitry. The bus-exchange circuitry simultaneously selects the other set of the two sets of dynamic random access memories for connection to an Output Bus. The digital video codes are retrieved from the set of dynamic random access memories in a specific order by component color and placed on the output bus. The specifically ordered video codes are multiplexed to form a serial stream of digital video codes. The serial stream is converted in an analog-to-digital converter to an analog signal that is of the format acceptable to field sequential display.
