Key requirements for high quality picture-rate conversion.

Past LCD-TV generations suffered from a poor motion portrayal, causing the blurring of moving objects. Hence, various techniques have been implemented to improve their motion portrayal, of which the widespread introduction of motion compensated picture-rate conversion in TV systems is an essential part. However, a careful design of such algorithms is critical, as otherwise very annoying artifacts may decrease their value. In this paper, we will give an overview of the key requirements for high quality motion-compensated picture-rate conversion, as implemented in state-of-theart system-on-chips, and visually illustrate the impact of individual measures on picture quality.
