Abstract:
The present invention provides an apparatus and a method for personal identification for performing a user identification or authentication on a TV or a set-top box (STB) required when providing a personalized service on a TV. The personal identification apparatus according to the present invention includes a remote control unit and a personal identification unit. The remote control unit includes a normal key and a special key, and receives a user authentication request, an identifier and a password through the normal key and the special key and delivers the user authentication request, the identifier and the password to the personal identification unit. The personal identification unit provides a user authentication interface screen based on the received user authentication request, determines whether to register the user is registered or not based on the received identifier and the password, and provides personalized service if the user is registered.

Abstract:
PURPOSE: A method and an apparatus for providing additional information of contents are provided to respect the watch of a contents program by minimizing an additional information providing screen of an appearance element appearing with contents. CONSTITUTION: A receiving terminal judges whether additional information of contents exists or not based on an indicator who is extracted from received metadata and overlays an appearance element of the contents (S300,S310). The receiving terminal outputs connection information for the download of simple additional information related to the appearance element and detailed additional information and downloads the detailed additional information from a server (S320,S330). The receiving terminal notifies the presence of the downloaded detailed additional information after the end of the contents and outputs the detailed additional information on a screen (S340,S350). [Reference numerals] (AA) Start; (BB) End; (S300) Judge whether additional information of contents exists or not; (S310) Output the appearance element of the contents by overlaying a graphic object on the appearance element of the contents; (S320) Output connection information for the download of simple additional information related to the appearance element and detailed additional information; (S330) Download and store the detailed additional information from a server; (S340) Notify the presence of the downloaded detailed additional information after the end of the contents; (S350) Output the detailed additional information on a screen

Abstract:
An apparatus and a method for classifying packets are provided to increase the efficiency of a memory by providing not only a single field search device according to the property of a single field but also plural search results in the first search device. A packet analysis and particular field extractor(110) analyzes packets, and extracts specific fields necessary for classifying packets. Plural single file search units(120) searches whether or not an item satisfies a certain condition for the extracted specific field. If to, the single field search unit extracts a pointer for the correspondent item and a hitting notification signal.
