An information processing method and apparatus of this invention are a method and apparatus for multiplexing data indicating information other than video information on a video signal and transmitting the multiplexed data. Modulated data is formed by inputting the data and modulating the input data. The video signal and the modulated data are input, and the modulated data is multiplexed on the input video signal. When the multiplexed data is output, the modulation mode or the multiplexing interval of the modulated data is controlled in correspondence with the type of input data, thus realizing a function of multiplexing data on a video signal and transmitting the multiplexed data in correspondence with the data type with a simple, small-scale circuit arrangement.
