The concept of motion adaptive colorplus encoding

The basic idea of colorplus is the phase segregation of high frequency luminance and chrominance signals. Due to the fact that colorplus encoding is reducing the temporal resolution to 25 Hz it cannot be used for higher motion velocities, otherwise heavy motions judder would be introduced. In picture areas with higher motion intra-frame averaging will be switched of and standard PAL encoding/decoding will be used. The luminance processing of motion adaptive colorplus (MACP) is shown. High horizontal frequencies will be faded of in picture parts with higher motion. This concept allows that colorplus is only switched of in critical areas. For most of the picture parts colorplus is used with all the benefits
