Video encoding device

Abstract

A video encoding system includes a video source providing a multiple frame video signal, a compressed data interface, a host interface and a video encoding device. The video encoding device includes a video input processor, a global controller, a motion estimation processor, a digital signal processor and a bit-stream processor. The video input processor receives the video signal. The global controller controls the global operation of the video encoding device. The motion estimation processor is connected to the global controller. The digital signal processor is connected to the global controller and to the motion estimation processor. The bit-stream processor is connected to the digital signal processor, the global controller and the compressed data interface. The global controller stores encoding commands received from the host interface thereby programming the video input processor, the motion estimation processor, the digital signal processor and the bit-stream processor.
