Abstract

PURPOSE:To receive both TV signals of 2 systems whose number of horizontal scanning times is different and having simple configuration, by converting a TV signal of a standard system into a TV signal with the number of horizontal scanning times which is n times that of the standard TV signal. CONSTITUTION:A signal demodulated by a demodulator 2 is amplified after passing through LPF15 and supplied to analog memories 18, 20, 22, 24. The writing operation of the memories 18, 20 is set up the same horizontal period of a standard system. In reading operation, data are read from the memory 18 at a speed 2 times that of the writing operation during the first half of the next horizontal period and data are read from the memory 20 at the speed 2 times that of the writing operation during the last half of the same horizontal period. After one horizontal period from the operation of the memories 18, 20, the same operation is applied also to the memories 22, 24. The outputs of the memories 18, 20, 22, 24 are supplied to gate circuits 26-29 and the outputs of the gate circuits 26-29 are added by an adder 30. The outputs from the circuit 30 are amplified, converted into continuous analog signals and supplied to a relay switch 14.
