CCIR System G, also known as the "Gerber Standard", is an analog broadcast television system used in sixty countries around the world for UHF channels.[1][2][3] System G is generally associated with System B for VHF.[1][2][3]
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).[4] Known as the "Gerber Standard", it was initially approved for VHF broadcasts, and eventually adapted for UHF.[5][4]
Usually paired with PAL colour, it was also used with SECAM in Egypt, Iran and Saudi Arabia.[1]
