摘要:
Disclosed is a user history based multimedia service system, wherein user history data include a multimedia consumption type and/or consumption behavior of the user. The consumption type data includes a start time or end time of the multimedia content consumption (i.e., simple view data), content recording time and format, content backup time and format, and content transfer time and format. The consumption behavior data includes a content access/play data such as a normal finish, skimmed, skipped, slowed, or replay, and a stopped data of the content access/play. The consumption type or consumption behavior data include information on program identification and information on access to the consumption type/consumption behavior data. The respective data is provided for each user and program.

A user preference information data structure which is capable of classifying and setting user's preference information regarding multi-media contents with multiple items to thereby provide users with user's request-based whole or partial multi-media information, and a method for providing multi-media information by using the user preference information data structure. The multiple item user preference information data structure for multi-media contents comprising: single item user preference information for single items related to the multi-media information; and multiple items user preference information for multiple items formed by combining the single items.
摘要:
A user preference information structure having a multiple hierarchical structure in which an information is provided to a user according to a user preference in a multi-media environment consisting of an information provider and an information user, comprising user use information by using information desired by the user; user preference information of information desired by the user; and individual user preference information that is differently set depending on situations in which the user is put and positioned in a sub-tree of the user preference information. The hierarchical data structure is able to provide the user preference for providing information desired by the user is provided depending on the environment, based on which various information can be provided. The hierarchical data structure constructing the user preference makes it possible for the user to receive information fitting the situation in which he or she is put by using a proper individual user preference information, automatically or according to user's selection.
摘要:
The present invention relates to a video reproducing apparatus and an intelligent skip method, which can provide an intelligent skip. Particularly, there is provided an apparatus and method for forward or reverse intelligent skips based on Group of Shots (GOS) using shot information of contents.
摘要:
The present invention relates to a non-linear reproduction control method of multimedia stream and an apparatus thereof, the present invention comprises judging a skip direction by interpreting whether a skip request is a forward skip or a backward skip when the skip request is inputted from the user, determining a skip unit by judging whether the user request is a big unit or a small unit, selecting a structural information or semantic information change point of the multimedia stream mostly adjacent to the present reproduction position as a reproduction resume point on the basis of the determined skip direction and skip unit or selecting the reproduction resume point by using the set temporal offset from the preset reproduction position, accordingly it is possible to.
摘要:
A dynamic searching method and apparatus of video contents is disclosed. The dynamic searching apparatus of video contents according to the present invention determines a normal replay section and a fast forward replay section the shot index information with considering current replay location and shot index information and replays the video contents from the current replay location at the determined corresponding speed according to the sections alternatively so as to replay video contents. Here, audio is replayed along with the video in the normal replay section.

Disclosed are a method of constructing information on associate meanings between segments of a multimedia stream, which can describe the cause/effect or abstract/detail relationship between segments of the video streams to efficiently browse the video stream and a method of browsing a video using the same. The present invention defines the cause/effect or abstract/detail relationship between the segments, event intervals, scenes, shots, etc. existing within one video stream or between the video streams, and provides a method of describing the relationship in a data region based on the content of a video stream as well as a method of browsing a video by using the information on the cause/effect or abstract/detail relationship obtained by the aforementioned method. Accordingly, a video browsing on associate meanings is available with easy manipulation and easy access to a desired part, thereby providing an effective video browsing interface for easy browsing of desired segments in a short period of time.

A rijndael block cipher apparatus including an operational unit that efficiently performs a round operation for encrypting/decrypting a rijndael block cipher and an encryption/decryption method thereof are disclosed. The rijndael block cipher apparatus is mounted in a mobile terminal such as a cellular phone and a PDA or a smart card, which requires a high-rate and small-sized cipher processor, and can encrypt and decrypt important data that requires security at high speed and perform the round operation with respect to upper 64 bits and lower 64 bits which are divided from 128-bit input data. Thus, the cipher apparatus can reduce the time required for encryption/decryption of the rijndael block cipher and the size of the apparatus.

A single-side embossed color steel sheet, and a method for manufacturing the same are disclosed. The steel sheet comprises a steel sheet substrate, a zinc or zinc alloy-plated layer, a non-chromate or chromate pretreated layer, a primary coat paint layer of modified epoxy or modified polyester, a color base paint layer, a printed layer, and a top coat clear paint layer. The color base paint layer comprises a polyester resin as a main resin, a melamine resin as a crosslink resin, a crosslink accelerator, other additives, solvent, etc. The printed layer exhibits a feeling of solidity with various feelings of texture and colors. The top coat clear paint layer serves to protect the printed layer from contaminants. The color steel sheet exhibits a remarkably enhanced feeling of solidity at an irregular surface thereof, and has enhanced contaminant resistance properties and environmental friendliness, thereby satisfying requirements for aesthetic design and functionality of products.

A method and home network system for authentication between a remote terminal and a home network, which are connected with each other through a network, using a smart card are provided. The method includes enabling access between the remote terminal and the home network through the network, performing authentication using first shared secret data stored in a server smart card connected to the home network and second secret data stored in a client smart card connected to the remote terminal, creating a security tunnel between the remote terminal and the home network when the authentication succeeds.
