In the transmitting position of DBS TV program the caption data are subtlely inserted into the vertical blanking gap of TV signal, which is transmitted with TV program to the satellite. In the receiving position the caption data are retrieved from the vertical blanking gap and accurately converted into TV caption signal. The way that the caption data are inserted in the transmitting position and retrieved from the receiving position is based on the time code of program as synchronous signal, so the caption can be displayed very accurately.
