Abstract:
PURPOSE: An image providing apparatus is provided to automatically update or upload an image through an event setting. CONSTITUTION: A storage unit(123) stores an image. A receiving unit(121) receives an event related with a predetermined image. An additional information extraction unit(122) extracts additional information from the stored image. A filtering unit(124) filters one or more image corresponding to the event based on the extracted additional information. A transmitting unit(125) transmits the filtered image to outside.
Abstract:
PURPOSE: A continuous reproduction method and a device applying the same are provided to continuously reproduce the content in one certain device if another device is powered off while reproducing the content. CONSTITUTION: A TV transmits a broadcasting reproduction notification message to a home server if a broadcasting reproduction starts(S205~S210). The broadcasting reproduction notification message to an AP(S215). The AP set a connection after finding a mobile phone through a scanning(S220). The AP transmits a user-out message to a home server(S235). The home server transmits the continuous reproduction request message to the TV(S260).
Abstract:
PURPOSE: A method and a device of predicting preference rating for contents, and a method and a device for selecting sample contents are provided to input preference rating information of users included in a similar user list through machine learning algorithm, thereby predicting preference rating about contents of a user. CONSTITUTION: A similar user information receiver(530) receives similar user list about users from a server. The server stores contents using information which is collected about contents of the same kind of contents. Through instrument learning algorithm, a preference predictor(540) inputs preference information of user included in the similar user list. The preference predicting unit predicts preference about the contents of users. A sample contents obtainer(520) obtains preference about sample contents.
Abstract:
PURPOSE: A method and a device for recommending content are provided to enable the first user to search recommendation contents which is similar to a content which is currently using by using received meta data. CONSTITUTION: Meta data about contents which the second user holds is received from the second users who have similar contents preference to a content preference of the first user(120). Recommended contents which is similar to content which the first user is currently using is searched by using the received meta data(130). Information about the searched recommended contents is outputted(140).
Abstract:
A managing method of a neighbor node having an active node and a similar characteristics, an apparatus thereof and a recording medium are provided to search the node having a special characteristic value similar to the active node at minimum time without using the server. A neighbor node management apparatus produces a neighbor list including adjacent node information(510). The neighbor node management device selects a parent node(520). The neighbor node determines a conformity parameter(530). The neighbor node management device updates the neighboring list of the active node based on the determined conformity parameter(540).
Abstract:
A header compression and packet delivery method in a sensor network and a device therefor are provided to enable a node which transmits data to transmit the data in a type suitable for a sensor node which receives the data, thereby efficiently delivering a packet. An inquiry message transmitter(210) transmits an inquiry message which inquires about whether a sensor node within a sensor network supports an adaptation layer function, to the sensor node. A reply message receiver(220) receives a reply message for the inquiry message. A decider(230) analyzes the reply message to decide whether the sensor node supports the adaptation layer function. If so, a header compressor(240) compresses an IP(Internet Protocol) header within a packet, and makes the IP header intact if the adaptation layer function is not supported. A packet transmitter(250) transmits the packet to the sensor node.
Abstract:
A method and an apparatus for transmitting and receiving data are provided to prevent data loss in data transmission and the inefficiency of data transmission by transmitting data in consideration of the receiving environment of a receiving device. A first device(31) transmits an INVITE message to the second device(301). A second device(32) transmits an OK message to inform the first device that the INVITE message has been normally received(302). The first device establishes a session by transmitting an ACK message in response to the OK message(303). Then the first device transmits and receives data through the established session(304). In case the first device decides to execute handover(305), the first device transmits an INVITE message to the second device again(306). In the same manner, the first device receives an OK message, and transmits an ACK message, and establishes a session(307,308). The first device transmits and receives data through the established session(309). The first device transmits an INFO message to the second device(310). In response to the INFO message, the second device transmits an OK message to the first device(311). The first device transmits and receives data, based on the information contained in the INFO message(312). If every data communication comes to an end, the first device finalizes data transmission and reception by transmitting a BYE message to the second device and receiving an OK message(313,314).
