A television signal digitizing method reduces the quantity of information without deterioration of image quality when digitizing progressive-scanned signals. The method uses a step of dividing a progressive-scanned information into two complementary interlaces, that is, an interlace 1 and an interlace 2; a step of converting luminance information in the interlace 1 to digital information whose sampling frequency is X; a step of converting chrominance information in the interlace 1 to digital information whose sampling frequency is Y; and a step of generating supplementary information.

An encoder/decoder can insert and demodulate an information signal without affecting a video signal, the information signal being not analyzed, modified and deleted easily. The non-inverted and inverted information signals are inserted into two horizontal lines having a strong correlation in the same field or different fields separated by at least one field of the video signal. A difference of the inserted information signals is obtained by a combination of a delay circuit and a subtracter. Field difference signals Sx and Sy are applied to a band pass filter and are generated by a PSK generation circuit. Generated output signals Qx and Qy are converted into unit information by a majority decision logic circuit and are stored in a memory. A unit information group consisting of a predetermined number of stored bits is used to generate the meaningful information. The inserted information signal has a low level and is inserted in the video period and the unit information is generated by the field difference. Thus, the information signal cannot be analyzed, modified and deleted easily.

Encoder/decoder of information upon/from a video signal

A parallel pulse transmission system, wherein the sending side converts original signals into line coded signals of a block coding type (mBnB line codes, m/2.gtoreq.2/3, n.gtoreq.3) and transmits them after aligning the timings of the blocks receiving side. The regenerates of the systems transmitted line codes and thereafter, aligns the timings of blocks of the line codes.
