MUNICH, Germany In the run-up to the IFA consumer electronics trade fair, NXP rolls a new video post processor chip that, according to the company, improves HD images by a series of 'smart' algorithms.
The PNX5100 device is based on the company's Nexperia multimedia processor platform and is to be used by TV set OEMs to improve the motion picture quality. Main functions are upconversion and motion estimation. The device can be used as a stand-alone video postprocessor or as a companion IC with a main TV processor.
NXP promises users of the device solutions for a range of problems HD TV technology is dealing with. For instance, when video material is upconverted from the usual 60 frames per second to 120 fps, images need to be interpolated which in the case of rapidly moving objects leads to a class of artefacts called halo. The new chip does extensively away with this effect as well with judder, the vendor promises.
Further, the device uses algorithms that dynamically adjust processing parameters, NXP says. Thus, the user benefits from a wider color gamut and better contrast. The PNX5100 supports HD TV with full resolution of 1920 x 1080p.
Besides the processor running the software, the PNX5100 contains hardware pre- and post-processing functions and a 'universal input processor'. For designers, NXP offers a reference design toolkit.
