PURPOSE: To obtain a transmitter improving deteriorated S/N at modulation by modulating and multiplexing two left/right systems of video signal, audio signal and synchronizing signal through one cable in the 3-dimensional television video signal transmitter. CONSTITUTION: An arithmetic processing section 2 is provided in a 3-dimensional video image transmitter 1, a video signal R of a right camera 3 and a video signal L of a left camera 4 are used to generate signals A=(L+R)/2 and B=(L-R)/2. A modulation section 5 multiplexes modulated base band signals A, B and the multiplexed signal is sent through one cable. Noise (n) at modulation is produced and the signal B becomes B=(L-R)/2+n. A demodulation section 6 demodulates the signals to obtain signals A, B. An arithmetic operation processing section 7 obtains signals L=A+B-n and R=A-B+n. A 3-dimensional device 8 mixes the video signal R of the right camera 3 and the video signal L of the left camera 4 on a display device 9 to cancel noise of a reverse code and to improve the S/N. |
