Abstract: A method for updating contents of a Digital Media Server (DMS) in a digital living network alliance system (DLNA) is disclosed. An update process is performed through a periodic update event in a Digital Media Player (DMP) that receives all content information of the DMS. Upon determining that information loss has occurred in the update process, the DMP sends to the DMS a request for information about a list of items possessed by the DMS. The DMP receives the requested information about the list of items and compares the received information about the list of items with information about pre-stored items to obtain a comparison result. When a difference occurs as the comparison result, all information about contents of the DMS is obtained through a browse action. When the difference does not occur as the comparison result, the update process is continuously performed.

Abstract: Disclosed is a channel changing method in a digital broadcasting service. According to the channel changing method, a subscriber device provided with a channel change protocol that operates on a TCP/IP layer transmits an input channel change message through the channel change protocol, and a channel change server that received the channel change message receives a confirmation message that includes channel information according to channel change information included in the channel change message, and transmits data of a requested channel to the subscriber device.

Abstract: A method for providing a user interface configured using three frames for a Digital Media Player (DMP) in a Digital Living Network Alliance (DLNA) system. Each of all source, renderer, and menu items of the DLNA system is set to one axis of a set of axes. Two predetermined axes of the set of axes and a contents list are selected according to selection by a DMP user of an operation to be performed within the DLNA system. A user interface of the DMP is configured using two frames for displaying the two predetermined axes and one frame for displaying the contents list.

Abstract: A system and method for Digital Living Network Alliance (DLNA) system is disclosed that provides data service of a digital broadcast. The DLNA system includes a digital media server for providing information about a broadcast A/V and data so as to handle a request for the data when a digital broadcast is requested, the digital media server receiving the digital broadcast and dividing the received digital broadcast into a broadcast A/V part and a data part so as to download the broadcast A/V part and the data part, respectively, and a digital media player for requesting the digital media server to transmit information about the digital broadcast, and to transmit data after receiving information about the broadcast A/V part and the data part from the digital media server, and for receiving and carrying out the requested data.

Abstract: Disclosed is a broadcasting system and method for transmitting/receiving a broadcast data in a broadcasting system, which reduces an application download period by efficiently utilizing a data broadcasting stream and a return channel for application download when a reception terminal receives a data broadcast. The broadcasting system and method includes a data broadcast reception terminal to receive the broadcast data and a bi-directional broadcasting server to communicate with the data broadcast reception terminal through a return channel: the data broadcast reception terminal receives a data broadcast stream during one broadcast transmission period, and requests the bi-directional broadcasting server to transmit a portion of the data broadcast stream (e.g.

Abstract: An apparatus to provide digital broadcasting data using a Wireless Local Area Network (WLAN) includes: a digital broadcasting processor adapted to receive, demodulate, decode, and output multi-channel digital broadcasting data; a transcoder adapted to receive the demodulated digital broadcasting data from the digital broadcasting processor, to convert the digital broadcasting data into a format transmittable over a Wireless Local Area Network (WLAN), and to output the converted digital broadcasting data; and a WLAN processor adapted to transmit the converted digital broadcasting data to a wireless terminal device connected to the WLAN.

Abstract: A television (TV) portal services apparatus and method using a message-based protocol that allows management and control for various service items by providing a consistent message-based framework in the TV portal service. Further, it is possible to implement new applications by providing a tool for association between individual services, resulting in technical efficiency in implementing a server as well as a terminal, and implementation of flexible services by standardizing an Application Program Interface (API) for the TV portal service.

Abstract: A method for servicing digital broadcasting, capable of defining a control message necessary for servicing digital broadcasting of a SD (Standard) level and a HD (High Definition) level through, a network of, for example, a x Digital Subscriber Line, by directly requesting, at a client, a digital broadcasting server for a session connection, and establishing a session by receiving a confirmation from the digital broadcasting server. Also, a channel change can be requested by directly requesting, at the client, the digital broadcasting server for a channel change, and changing a channel by receiving a confirmation from the digital broadcasting server. Other direct client-server requests and confirmations include a message for checking a status of the client and a session termination.
