Patent ID: 7808561

Claim:
A broadcasting signal transforming apparatus for transforming digital television (TV) broadcasting signals into digital radio broadcasting signals, comprising: a transport stream generating means for receiving and transforming TV broadcasting signals inputted from outside into digital TV broadcasting transport streams; a broadcasting transport format transforming means for transforming the digital TV broadcasting transport streams in conformity to a digital radio broadcasting transport protocol and generating digital radio broadcasting transport streams based on a radio broadcasting schedule; a broadcasting multiplexing means for multiplexing the digital radio broadcasting transport streams generated in the broadcasting transport format transforming means; a modulating/up-converting means for modulating the digital radio broadcasting transport streams multiplexed in the broadcasting multiplexing means in a modulation method for digital radio broadcasting and up-converting frequencies of the modulated radio broadcasting signals into radio frequency (RF) signals; and a high-power amplifying means for amplifying the RF signals obtained from modulation and up-conversion in the modulating/up-converting means to thereby transmit the amplified RF signals through a transmitting antenna.
