NXP Semiconductors has launched what it claims as the world's first video postprocessor with proprietary Motion Accurate Picture Processing technology, enabling TV manufacturers to improve high-definition (HD) motion picture on LCD TVs. This technology on NXP's PNX5100 video postprocessor combines movie judder cancellation (MJC), motion sharpness and vivid color management to successfully remove the visible halo and blur in fast moving scenes delivering an enhanced viewing experience for enjoying sports and action movies.

NXP's Motion Accurate Picture Processing technology uses a revolutionary up-conversion technique in conjunction with three-frame HD Movie Judder Cancellation and full motion-compensated up-conversion to 1,920 x 1,080p at 120Hz. The Automatic Picture Control (APC) feature dynamically adjusts the processing parameters used to obtain optimal improvement on every output frame. As a result, NXP's PNX5100 enables TV manufacturers to take advantage of the latest 1,920 x 1,080p at 120Hz resolution panels with wide color gamut for superior sharpness, richer color, dynamic motion and deep contrast.

"Until now consumers have only experienced the first phase of the HDTV evolution. NXP's advance in HD motion picture quality is unprecedented and will herald the second generation of HDTV," said Jos Klippert, senior marketing manager of digital TV systems at NXP. "Motion Accurate Picture Processing is a revolutionary technology that delivers dynamic improvements in motion, sharpness, contrast and color to offer the best consumer experience. Moreover, it reaffirms our leadership in R&D and demonstrates our understanding of consumer expectations from HDTV viewing today and in the foreseeable future."

The Nexperia PNX5100 integrated media processor cores provide a powerful video processing platform for motion estimation and up-conversion. The performance is extended with hardware pre- and post-video processing functions a universal input processor (UIP) and video composition pipe (CPIPE). It includes a dual-channel LVDS receiver and two dual-channel LVDS transmitters. This advanced postprocessor also provides PiP (Picture-in-Picture) and OSD graphics insertion capabilities. The PNX5100 supports high-end flat panel screen resolutions and refresh rates with formats including 1,366 x 768 at 120Hz and 1,920 x 1,080 at 120Hz.

The PNX5100 comes with a reference design toolkit that helps TV manufacturers cut time-to-market and development risks. Moreover, it can be used as a stand-alone video-postprocessor or as a companion IC with a main TV processor, allowing motion accurate picture processing to be performed as a feature enhancement.

The Nexperia PNX5100 will be available for mass production in Q1 2008.
