A three-dimensional television system comprising an adapted transmitter (1'), which in further respects does not differ from a color television system in accordance with the PAL, NTSC or SECAM-standard. The three-dimensional display in the standard receiver (2) is based on the use of two colors, an observer observing a color picture display screen (10) through differently colored glasses (19, 20). In the transmitter (1'), a first picture pick-up device (12) is coupled to an input of a matrix-coding circuit (4, 5) via a low-pass filter (14). The filter (14) has a bandwidth which is not more than the bandwidth of the color difference signal channels in the decoding-matrix circuit (7, 8) of the receiver (2). In order to improve the picture quality, a second picture pick-up device (13) may be coupled via a low-pass filter (17) having a wider bandwidth to a different input of the matrix-coding circuit (4, 5). |
