CEDIA 2009 Review: More Motion Flow Processing

By Richard Fisher • Nov 30 2009, 3:55am

Motion flow processing has played a huge role in the marketing of LCD product, turning what used to be negative into an unnecessary marketing positive. At first it was 120 Hz processing and now the big hype is 240 Hz processing; bigger numbers infer better. The common misperception is that motion flow processing is all about compensating for LCD pixel speed when actually the main purpose is to remove the potentially objectionable strobe effect of 30 and 24 frame content that appears most strongly with high contrast displays, like an LCD. All displays suffer from this artifact to some degree with contrast ratio playing the greatest role. For a deeper understanding...

By Rodolfo La Maestra • Nov 23 2009, 5:27pm

This series of three articles analyzes the current and future market for HD, the methods of distribution and the capabilities of the digital technology to distribute HD content to meet consumer expectations. This technology must also support other quantity oriented businesses and services that can potentially degrade the original HD vision and affect those that invested in HDTV equipment under the reasonable expectation of viewing uncompromised HD quality, not just digital. This is a dilemma of quantity vs. quality when DTV permits the implementation of both, sharing the same bandwidth.

The content production industry needs...
