The FRC 94xyH high-definition frame rate converter IC from Micronas aims to eliminate motion blur and film judder in HDTVs. Micronas claims that it is the first IC that can generate 120fps from 50/60Hz broadcast content and even from 24fps film sources. The device is also said to be the first IC that has a film de-judder solution for full HD 1,920 x 1080 DTV sets.

Display manufacturers are said to be working on various approaches to overcome the motion blur effect of LCD TVs. One method is to increase the image rate—more images give a more realistic portrayal of motion. The product is said to generate 120 images per second.

De-juddering is the process of converting film, originally shot at 24fps, to the typical TV display frame rates of 50Hz or 60Hz, using motion vector estimation and compensation. Micronas' proprietary truDHD motion compensation technology is said to increase the frame rate by generating additional frames. The device is touted to process images at full resolution. Micronas claims that the display delivers an image that is a perfect match to the source image. This is relevant for all FP displays, including plasma and rear projection TVs.

The FRC 94xyH works with a variety of video source material—PAL signals are converted to 100fps and NTSC signals are converted to 120fps. Intermediate rates of 75fps and 90fps are also supported. The product comes in a BGA-260 package and is currently sampling to qualified OEMs. Production is planned for Q3 2006. Prices for high quantities range from approximately Rs.1,062 ($24) to Rs.1,327.50 ($30), depending on the product version and volume.
