    摘要: An ultrasonic video display device may comprise a memory; a programmable logic device, which may comprise a VGA signal receiving module for receiving and demodulating digital video signals and a video signal processing module including a memory controller, a gamma correcting unit, a scaling processing unit, a filtering unit, a chrominance space converting unit, a chrominance sampling unit and an interleaved sampling controller. The ultrasonic video display may also include a first digital-to-analog converter having an input coupled to an output of the VGA signal receiving module to convert the digital video signals into VGA analog signals and to output the VGA analog signals. A second digital-to-analog converter may receive video digital signals, convert the video digital signals into video analog signals, and output the video analog signals.
