In contrast to the Grand Alliance's HDTV Standard, which is incompatible with the existing TV standards, the author submits the digital stereo compatible TV standard (NTSC-DSC) which is completely compatible with the existing TV standards and advances a new image quality of TV -- its 3D stereo visualization making the stereo TV like real television when remote viewers can see from new stereo TV sets pictures in the same manner as they can see these pictures directly by their two eyes without TV. The main issues of the compatible stereo TV are multiplexing of the coupled stereo TV signals into one TV stereo signal compatible with the existing TV standard NTSC (PAL, SECAM), and digital video data compression as the tool to achieve such multiplexing. This paper is concentrated on the specific description of the method and technique of the digital video data compression of the one stereo ('left') TV signal and then time-division multiplexing of such highly compressed digital 'left' TV signal-file inside the other original analog NTSC 'right' TV signal. The essential stereo visual redundancy of the coupled TV signals reflects the fact that these stereo TV signals look like mainly the same, like 'twins.' If the stereo base of stereo binocular TV camera is along the TV line scanning, then there is a lot of identical, corresponding runs of pixels in both 'left' and 'right' TV signals for any TV scanning line. Such identical twins-runs are set apart by the shift along TV line depending on the distance to according image objects from the TV camera. The possibility of the time-division multiplexing based on the information emptiness for time intervals of the standard TV signal occupied by playbacks of TV scanning.
