ABSTRACT:
A television receiver converts a television signal of a standard television system currently employed into a signal at a horizontal scanning frequency of n (an integer of 2 or more) times that of the original television signal, so that it can visually reproduce any one of a television signal of the standard television system and a television signal of a second television system, which has a horizontal scanning frequency of about n times that of the television signal of the standard television system. When receiving the television signal of the standard television system, the horizontal deflection circuit operates at a horizontal scanning frequency n times that of the standard television system. When receiving the television signal of the second television system, it operates at the horizontal scanning frequency of the second television system. For the reproduction of the converted signal with the n times horizontal scanning frequency, the interval between the adjacent scanning lines may properly be adjusted by moving them at the horizontal scanning period of the standard television system in the vertical scanning direction.
