PixelPlus

Pixel Plus is a collective term for several developed by Philips imagen enhancement method for 100Hz CRT TV, and later extended to image enhancement for flat screen TV.

Through intelligent digital signal processing, the at an image frequency doubling ( 100Hz TV ) is processed resulting problem of line overlays by the interlace method in high-resolution televisions optimized Pixel Plus further extrapolating ( upscaling ) of low-resolution television images ( conventional PAL resolution ) for display on HDTV flat screen.

Pixel Plus comes in both 100 -Hz television sets, as well as in progressive scan capable devices are used.

For standard PAL devices, the number of pixels is 768 à 576 lines in 4:3 and 1024 à 576 lines in 16:9 ( assuming square pixels ). The horizontal resolution is doubled by this method from 1024 to 2048 pixels.

Disadvantages

With the introduction of " 100 Hz " TVs went in TVs by caching and double letter of fields a TV functionality for the natural deinterlacing by the human eye lost. For trouble-free 100Hz image reproduction is therefore now intelligent image processors were necessary to avoid line flicker and disturbing comb effects. The introduction of flat panel TVs brought another problem with it. These have a single native image resolution. The intelligent image processor must have the image content so calculate that the lower resolution and blurs not notice. For difficult image content, such as fast diagonal movements or moving moiré patterns ( rennendes zebra or herringbone jacket ) fails, the image processor more frequently. There is also reversed at higher resolution of the transmitted signal than the native resolution of the device problems. The greater the difference between native and extrapolated image resolution, the more distorted and reduced the HDTV quality. Also, no additional details are displayed, but existing only interpolated.
