    摘要： An apparatus and method for receiving RF signals in a RF communication system are provided. The apparatus for receiving RF signals comprises a pre-processing unit for bandpass-filtering a signal received through an external antenna with a predetermined bandwidth and extracting a RF input signal having a desired frequency; a mixing unit for mixing the RF input signal provided from the pre-processing unit with a local oscillation signal having the same frequency as the RF input signal and generating a desired baseband signal; a noise-free-signal amplifying unit for shifting the desired baseband signal to a band that is free of effects due to 1/f noise, amplifying the shifted baseband signal, and re-shifting the amplified signal to the baseband; and a baseband processing unit for selecting a desired channel signal from the amplified baseband signal to be provided from the noise-free-signal amplifying unit and amplifying the selected signal.

    摘要： Provided are a method and apparatus for providing/receiving a service from a plurality of service providers. In the method, in order to receive a service from a plurality of Internet protocol television (IPTV) service providers, a client receives information regarding at least one of a feed that syndicates web information and a web-based application from a server of a service provider selected from the IPTV service providers. Then, the client requests the server to provide a service providing at least one of the feed and the application based on the received information, and receives the service from the server. Accordingly, it is possible to provide or receive web-based services via an IPTV network.
