Plan showing VHF frequency ranges for ITU Systems

At a CCIR Geneva meeting in July 1950, Dr. Gerber (a Swiss engineer), proposed a modified 625-lines system with a 7 MHz channel bandwidth (based on work by Telefunken and Walter Bruch). Known as the "Gerber Standard", it was initially approved for VHF broadcasts, and eventually adapted for UHF.

Usually paired with PAL colour, it was also used with SECAM in Egypt, Iran, and Saudi Arabia.
