HOME > Products > AV&Communication > VG22G1 The VG22G1 is an NTSC system data MPX signal generator conforming to teletext and inter-text broadcasting systems employed in Japan. Teletext and inter-text MPX signals generated in the VG22G1 is superimposed on horizontal blanking period of the composite video signal which is input from the external signal source, and the resultant signals are output from this main frame. In addition, output level and timing of the teletext and inter-text data can be set freely by using controls on the front panel. Also, designed to cope with teletext and inter-text systems, the VG29B2 is ideal as a signal source for R&D, manufacture and inspection of the data MPX decoder for TV, VCR and other related equipment. Features Testing similar to the actual broadcasting can be performed by using eight output lines Conforming to teletext system (VITS A: 9 pictures are internally generated) Conforming to inter-text system (VITS B: 2 pictures are internally generated) Generates one video signal (stair step pattern) Superimposing lines of MPX signal can be set from 10th H (or 320th H) to 22nd H (335th H) for each of VITS A to H The output level of MPX signal is controllable in a range of +/–20% Superimposing position of MPX signal for horizontal sync signal can be set in a range of +/-0.35 μsec
