A method and apparatus for transceiving television (TV)-content-related information based on a social network. A TV content sharing method for providing TV-content-related information to a plurality of TV users based on a social network includes receiving from a TV user a request to check in a TV content sharing service; providing real-time user information regarding users who check in a content checked-in by the TV user, in real time; and providing related service information regarding accessible related services in the social network in relation to the checked-in content.

Method and server for the social network-based sharing of TV broadcast content related information

A pre-emphasis circuit capable of controlling the slew rate of a signal output from a buffer that transfers the output signal to an output driver to increase the range of a controllable voltage step includes a first buffer, a second buffer, and an output driver. The first buffer buffers first and second main input signals having phases opposite to each other, outputs first and second main output signals, and controls slew rates of the first and second main output signals using at least one main control signal. The second buffer buffers first and second sub-input signals having phases opposite to each other, outputs first and sub-output signals, and controls slew rates of the first and second sub-output signals using at least one sub-control signal. The output driver generates first and second output signals having opposite phases using at least two control signals and the output signals of the first and second buffers.

A serializer serializes N data (N&#x3e;2) in N stages into a serial data stream. Each stage includes a logic section and a first inverter. The logic section receives i-th data (where i is less than or equal to N) of the N parallel data to output the i-th data or inverted i-th data in response to an active status or an inactive status of an j-th clock signal (where j is less than or equal to N) of the N clock signals. The first inverter receives the i-th data or the inverted i-th data from the logic section and inverts the i-th data or the inverted i-th data to output a first output signal. The output signal of the serializer may have reduced jitter even when the serializer operates in a high speed and a low power condition.
