This is very different from the color conversion system of VH8 system 5-basis VTRs such as AL system and NTSC system. In particular, in the European region, there is a strong demand for a device that can record and reproduce television signals of both the PAL and SECAM systems, because the PAL system and SECAM system of television broadcasting are adjacent to each other. VH8 system VTR uses a device that records and plays back SECAM system television signals using a method similar to the PAL system.
It records and plays back both SECAM and SECAM television signals. This SECAM signal processing method is called a pseudo-SECAM method.
