Extended Video Encoder with Pre-Processing of Interlace Signal

Some video coding standards for interlace video is specified by ITU and ISO organization, in which Macroblock level frame/field adaptive (MBAFF) method can get the best performance. Because of many kinds of Macroblock division methods to make it time-consuming for motion estimation, and when displayed on progressive screen, MBAFF can't solve the problem such as line crawling etc. An extended video encoder is designed in this paper, with motion-adaptive deinterlacing for pre-processing interlace video, and which can solve the display problems and the deinterlacing process filter can reduce noise of signal and enhance the input video signal quality, and improve the efficiency of encoder.
