RECEIVER
Document Type and Number:
Japanese Patent JP3450322
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a transmitter for transmitting a plurality of data streams by modulating a plurality of carriers whose frequencies are in an orthogonal relation to each other.
SOLUTION: The transmitter of this invention includes: a modulation section that modulates a carrier with a first data stream and a carrier with data streams other than the first data stream in a way of providing a power difference between the carriers; and an inverse Fourier transform section that transforms an output of the modulation section into a time base. The first data stream is audio information and the second data stream is information for configuring a video signal.
