Superimposing apparatus

摘要

A superimposing apparatus comprises an obtaining circuit for obtaining a first positional information from a video signal including the first positional information, a comparing circuit for comparing a second positional information read out from a storage medium with the first positional information obtained in the obtaining circuit, a varying circuit for varying a read-out position on the storage medium according to a compared result in the comparing circuit so that the second positional information coincides with the first positional information, a character signal generating circuit for generating a character signal by reading out from the storage medium a character information corresponding to the second positional information when the first positional information and the second positional information coincide, and a mixed signal generating circuit for generating a mixed signal for a superimposed display by mixing to the video signal the character signal generated from the character signal generating circuit.
