ABSTRACT:
A digital broadcast channel reception system and a portable terminal allow watching a digital broadcast on the terminal. In the examples, a receiver unit for receiving digital broadcasts transmits video data to a display unit, using its TX data manipulator, modulator, TX circuit, and antenna. The TX data manipulator manipulates the output from an OFDM demodulator into data to transmit from the TX circuit and appends error correction codes to the data. The modulator modulates the output from the TX data manipulator. A display unit for digital broadcast display receives video data transmitted from the receiver unit, using its antenna, TX/RX section, and modulator/demodulator. After error correction codes in the received signals are decoded by a TX/RX data manipulator, video data is extracted. After the video data is decoded by a MPEG4 decoder, a picture is output on the display.
