Abstract

PURPOSE: To enable to receive the reproduction signal directly, by superimposing the binary information signal as the additional information transmitted through the superposition on TV signal, again on the TV signal after converting into a lower frequency.
CONSTITUTION: The binary information signal of the additional information transmitted through superposition during the vertical blanking period of TV signal is picked up and written in the buffer memory 8, and the binary information signal is read out in a low frequency from this buffer memory 8. Further, it is recorded on the magnetic recording tape 7 through the superposition during the vertical blanking period of TV signal, the binary information signal reproduced from the tape 7 is written in the buffer memory 11, readout is made through the conversion into the original high frequency from this memory 11, and it is output with superposition on the TV signal.
