4、PW1235 General
2.2.
PW1235 supports standard digital video signal ， incorporates deinterlacing、
scaling .the PW1235 is able to effectively deinterlace video input by creating motion vectors that
follow frame-to-frame movement, and provide clear, progressive output in both analog and digital
formats. The PW1235 integrates input interface、MEMORY control circuit、picture improve、
output interface circuit、I
