Communication system using wired and wireless network {COMMUNICATION SYSTEM USING WIRED AND WIRELESS NETWORK}

The present invention relates to a communication system using a wired or wireless network in Internet-based IPTV (Internet Protocol Television), in particular, an Internet service provider network, a telephone network, a local area network, a personal area network, or other wired lines. It relates to a communication system using a wired or wireless network such as a network.

Internet service providers, cable television networks and other data providers generally transmit and receive data using conductive wires and cables. Traditional approaches to transmitting signals (eg, data) over a transmission medium such as wired or cable are to modulate the signal through the medium at a frequency within which the medium can electrically conduct the signals. Because of this traditional approach, the bandwidth of a particular medium is limited to the spectrum within which the current yields a range in which the medium can transmit the signal electrically through modulation. As a result, many expensive and complex schemes have evolved to increase bandwidth in traditional conductive wire or cable systems using sophisticated switching schemes or signal time-sharing allocation schemes. For each of these methods, the data transmission system was partly complex and expensive, as it remained to admit the traditional theory that the bandwidth of a wired or cable is limited by its conductive capacities.

In addition, in the above method, the receiving station and the transmitting station generally receive a broadcast signal from the outside and transmit it to another display device or the Internet connected thereto, such a so-called set top box (STB).
