Abstract: A tuner block in which a modulator and an IF/demodulator circuit are integrally formed. The tuner block has a casing for accommodating a tuner, the IF/demodulator circuit and the modulator, and sixteen pins consecutively disposed at an outside of the casing. A number of the pins is reduced as compared with a conventional tuner block by supplying an electrical power to the modulator and the tuner through a common pin, dispensing with pins carrying unnecessary signals and pins which carry no signal and rearranging other pins. Potential for noise and interference between signals is reduced by maximizing displacements of connector pins which carry signals which are likely to interact. A switching arrangement provides for utilizing either a conventional tuner block or a tuner block according to the present invention on a circuit board.

Abstract: A video signal recording/reproducing apparatus for recording/reproducing a high resolution video signal wherein the video resolution is enhanced by shifting a carrier frequency to a higher band in frequency modulation in a VCR's video signal recording mode, and by differently setting the frequency characteristics depending on the presence of a color signal in the video signal.

Abstract: Outernet DNS searching units are included in a host, a DNS server, a router where a DNS server is registered, and a router where a DNS server is not registered, allowing Internet-enabled terminals to automatically search for a DNS server in an outernet. The host creates a DNS search message and transmits it to a subnet to which the host belongs so as to receive a response message. If no response message is received from the subnet (i.e., a DNS server is not connected to the subnet), the DNS search message is transmitted to an outernet to which the host does not belong, to which a DNS server is connected. Further, when a DNS server does not respond to a DNS search message from a host, a hop limit is increased to resend the DNS search message, thereby preventing waste of network bandwidth and easily detecting the closest DNS server.
