Abstract

The home server is a home network server for receiving a broadcasting signal transmitted from a broadcasting station and for transmitting the received broadcasting signal to a wireless terminal by wireless. The home server includes: (i) a digital broadcasting signal receiving section for receiving a digital broadcasting signal, obtained by modulating a first digital signal, as the broadcasting signal; (ii) a digital broadcasting signal demodulating section for demodulating the digital broadcasting signal to the first digital signal; (iii) a TS signal channel coding section for modulating the demodulated first digital signal to a digital wireless signal that the wireless terminal can received by wireless; and (iv) a digital wireless signal transmitting section for transmitting the digital wireless signal to the wireless terminal by wireless. On this account, the home server can transmit the received digital broadcasting signal to the wireless terminal by wireless, with no deterioration in an image quality, a video image quality, and/or a sound quality.
