Abstract: An apparatus and a method are provided for automatically converting a user interface (UI). A Bluetooth-automatic authentication function is performed so as to automatically convert a current set UI to a stored UI corresponding to an authenticated Bluetooth terminal. In order to automatically convert UI of a terminal which is automatically authenticated in a short communication mode, at least one terminal ID for automatic authentication and UI configuration information corresponding to the terminal ID are set. When a terminal ID for automatic authentication is searched in a short distance communicating mode, a terminal corresponding to the searched terminal ID is automatically authenticated. The present UI configuration information corresponding to the automatically authenticated terminal is automatically applied to a current terminal UI, so that a current UI such as a main screen and a main menu category can be automatically converted to a preset UI corresponding to each authenticated Bluetooth terminal.

Abstract: Disclosed is a method of managing a Motion Picture Expert Group-2 Transport Stream (MPEG-2 TS) in an object unit of an MPEG-4 by efficiently matching the MPEG-4 with the MPEG-2 TS, in order to broadcast an internet protocol (IP). The method manages MPEG-4 object information in an MPEG-2 TS status, by adding the object information to a program map table (PMT) in the course of converting an MPEG-4 data into an MPEG-2 TS. The method includes the steps of: a) receiving an MPEG-4 SL (Sync Layer) to be transmitted as an MPEG-2 TS; b) acquiring an object information from the MPEG-4 SL; c) aligning the acquired object information corresponding to a program map table (PMT) of the MPEG-2 TS; and d) creating an MPEG-2 TS which has the PMT corresponding to the object information.

Abstract: An apparatus for IP streaming capable of smoothing a multimedia stream is disclosed. The apparatus transmits real-time broadcast through an Internet protocol (IP) network and reduces transmission loss by lowering the influence derived from jitters in an IP network having a burst characteristic. The apparatus is capable of smoothing a multimedia stream in a multimedia stream service outputting data through buffering based on a packetized elementary stream packet unit, which is easy to synchronize voice with video and suitable for the real-time multimedia stream service.

Abstract: Disclosed is a method for operating a wavelength-division-multiplexed passive optical network (WDM-PON) including an optical line terminal (OLT) and a plurality of optical network units (ONUs), each of which is connected to the OLT and communicates with the OLT. The method comprises the steps of transmitting a first control channel including allocation information of downstream data channels and allocation information of time slots for the downstream data channels to each of the plurality of ONUs; and transmitting downstream data to the plurality of ONUs using their associated downstream data channels, each having at least one time slot, based on the information included in the first control channel.

Abstract: A method of enabling transmission of a time-critical control signal event in a sync frame period, such as a pause signal that is generated when the receive buffer of an Ethernet switch is filled with packets beyond a threshold due to congestion of uplink asynchronous data, is disclosed. To transmit time-critical information in a synchronous Ethernet system, a current transmission period is checked upon detection of a time-critical event. If the current transmission period is a sync frame period, time-critical control information is generated, inserted into the first sub-sync frame after the time-critical event, and transmitted. If the current transmission period is an async frame period, a control frame including the time-critical control information is generated and transmitted.
