Together, the GF9331 and the GF9330 provide 10-bit broadcast quality de-interlacing for standard and high-definition video signals up to 1080p60. Although the GF9330 can fully function as a stand alone de-interlacer, the GF9331 provides added features in the form of a filter selection control bus that enables multi-directional edge and adaptive 3-field vertical motion detection. Edge detection and interpolation removes the edge artifacts that tend to occur while de-interlacing on shallow horizontal edges while vertical motion detection reduces motion artifacts. Filter selection controls are sent to the GF9330 on a pixel-by-pixel basis. The GF9331 integrates all the necessary line delays for the motion and edge detectors. The GF9331 also provides seamless interfaces to off-chip SDRAMs that form the required field delays. Ordering Information Block Diagram Part Number Package Temp.
