Standard converter
A standard converter is a device that converts a video signal (e.g. PAL , NTSC or SECAM formats) from one television standard to another. A standard converter is z. B. needed to play a video from America with a German video player.
Such a device is basically a TBC , with the additional z. B. image line and frame interpolations can be performed. The latter is a challenge that has still not been satisfactorily solved, even with expensive devices that are used by professional users such as B. TV channels are used. The result of standardized material is either jerking (NTSC to PAL) or streaking movements (PAL to NTSC).
Standard converters built into VHS machines are usually only suitable for making material from a third-party standard visible in your own system. Often only the color transmission system is changed here. This creates a signal that differs from PAL only in the speed of the time sequences. Tolerant televisions can still display this signal.
Today there are both analog standard converters (bucket chain storage method) and digital standard converters (Domino converter, Aurora World Converter).
