    • Disclosed are a personal video recorder (PVR) using metadata and a recording control method thereof that facilitates the selective recording of user-preferred segments of a broadcast program in real time. The PVR includes a broadcast receiver for receiving the digital broadcast and dividing the digital broadcast program into video data, audio data, and metadata. The PVR also includes a DS analyzer for analyzing the metadata and outputting program-related information corresponding to the digital broadcast program, a user input unit for receiving recording preference information from a user for recording the digital broadcast program, a program information processor for filtering the program-related information using the user-supplied recording preference information, a synchronous buffer for temporarily storing the video data and the audio data, a recording unit for encoding and storing the video data and the audio data temporarily stored in the synchronous buffer, and a control unit for comparing the filtered program information with the recording preference information and controlling the synchronous buffer and the recording unit in accordance with the results of a comparison.

    • A photoelectric cross-connect system for an optical-communication system minimizes service recovery time when an error is generated. A plurality of nodes are connected by an optical-transmission line wherein each nodes automatically recognizes a data rate of an input signal and communicates over a redundant channel with an adjacent node when there is a certain type of error. An optical-receiving unit receives an optical signal performs O/E conversion. A main optical-transmitting unit recovers clock and data signals according to the converted signal and sets a data rate according to the converted signal for subsequent transmission; a redundant optical-transmitting unit recovers a clock and data according to the converted signal and sets a data rate according to the converted signal for subsequent transmission A switch provides selectively connection state between the optical-receiving unit and the main optical-transmitting unit and between the optical-receiving unit and the redundant optical-transmitting unit.
    • 用于光通信系统的光电交叉连接系统在产生错误时将服务恢复时间最小化。 多个节点通过光传输线连接,其中每个节点自动识别输入信号的数据速率,并且当存在某种类型的错误时,通过冗余信道与相邻节点进行通信。 光接收单元接收执行O / E转换的光信号。 主光传输单元根据转换的信号恢复时钟和数据信号,并根据转换的信号设置数据速率用于随后的传输; 冗余光传输单元根据转换的信号恢复时钟和数据,并根据转换的信号设置数据速率用于后续发送。A交换机选择性地提供光接收单元和主光传输单元之间的连接状态,以及 光接收单元和冗余光发射单元。

    • A broadcast/communication convergence system, and an FTTH (Fiber To The Home) system that can accommodate broadcast signals of various channels and variable band signals by converging broadcast and communication signals and transmitting the converged broadcast and communication signals using an IEEE 1394 transmission method serving as a standard interface in the FTTH system for broadcast/communication convergence. An OLT (Optical Line Terminal) transfers a plurality of broadcast signals and a communication signal received from external broadcast and communication providers through a single optical signal (A). An ONU (Optical Network Unit) receives the optical signal (A) from the OLT, separates the received optical signal into the plurality of broadcast signals and the communication signal, opto-electrically converts the plurality of broadcast signals and the communication signal, switches the converted broadcast signals subscriber by subscriber, combines the converted communication signal with the switched converted broadcast signals.
