Abstract: Motion Compensated Temporal Filtering (MCTF) has made a significant impact on the DTV industry by saving bits and allowing operators to deliver consistently higher quality video at lower rates than ever before. All content tends to contain some noise, the random and unwanted portion of a signal. Even modern facilities equipped with the latest digital production equipment will inevitably import noisy content unless the incoming material is thoroughly cleaned. Noise reduction (NR) and filtering can substantially improve the video received by a viewer if the right techniques are applied to remove noise prior to compression. Selectively removing noise is a challenge because it shares space with valuable picture detail. An ideal noise reduction process will allow powerful suppression of random noise while preserving clean video content. The major advantage of MCTF is its inherent ability to remove noise without introducing motion blur artifacts. This technique has been known for many years, but the costs associated with a high processing overhead has kept it from being commercially viable. This paper will explain how integration of the new MCTF technique with existing technologies has dramatically improved video-compression efficiency.

bio
Neil Brydon currently leads the marketing team responsible for development and delivery of Harmonic's MPEG-2 encoder family. When he first joined DiviCom (now part of Harmonic Inc.) in 1997, he focused on video compression and pre-processing, a crucial feature of successful digital television system design. Prior to joining Harmonic, Brydon developed and managed evaluation and selection processes of new video technologies for the ITV Technology Center in the U.K. Ultimately, the ITV DVB team was responsible for the design and implementation of the world's first digital terrestrial service. Brydon received a B.Sc. Honors degree in electrical and electronic engineering from the Robert Gordon Institute of Technology, Aberdeen, Scotland.
