    • PURPOSE: A buffer management device for reproducing streaming multimedia and a method thereof are provided to consecutively reproduce the streaming multimedia when a handover process is executed in a wireless network. CONSTITUTION: A control unit(440) determines the handover of a first wireless network from a second wireless network. A second network reception unit(420) receives delay multimedia data. The second network reception unit buffers the received delay multimedia data to a second buffer. A decoding buffer(430) provides the delay multimedia data buffered to the second buffer by receiving data. A first network reception unit(410) receives the multimedia data. The first network reception unit buffers the received multimedia data to the first buffer. [Reference numerals] (410) First network reception unit; (411) First buffer; (420) Second network reception unit; (421) Second buffer; (430) Decoding buffer; (440) Control unit

    • PURPOSE: An intelligent broadcasting network system is provided to control a transmission apparatus and a repeater based on an analysis result by controlling a reception network according to a broadcasting receiving state. CONSTITUTION: A transmission network(120) collects transmission state information related to one or more transmission apparatuses and one or more repeaters. The transmission apparatus and the repeater provide a broadcasting signal. The transmission network includes one or more repeaters and one or more transmission apparatuses. A power line communication transmission network(130) transmits the transmission state information and the reception state information using a power line. An intelligent broadcasting network management apparatus(140) analyzes transmission state information and the reception state information. The intelligent broadcasting network management apparatus controls the transmission network and the reception network based on the analysis result.

    • PURPOSE: An encoding apparatus of a T-DMB system and encoding method thereof are provided to improve an decoding performance by enabling a user to selectively decode signaling information. CONSTITUTION: A first convolution encoder(103) encodes the output of a first energy dispersal scrambler(101). A conditional access scrambler(107) performs the scrambling of the output of the first interleaving unit in order to provide the output of the first interleaving unit to a receiver who has a broadcasting reception right. A MSM(Main Service Multiplexer)(115) multiplexes the output of a second interleaving unit. A broadcasting signal creation module(120) creates an OFDM(Orthogonal Frequency Division Multiplexing) signal for a digital broadcasting transmission.
    • 目的:提供一种T-DMB系统的编码装置及其编码方法,用于通过使用户能够选择性地解码信令信息来提高解码性能。 构成:第一卷积编码器(103)对第一能量散布扰频器(101)的输出进行编码。 条件访问扰码器(107)对第一交织单元的输出执行加扰,以便将第一交织单元的输出提供给具有广播接收权的接收机。 MSM(主服务复用器)(115)多路复用第二交错单元的输出。 广播信号创建模块(120)创建用于数字广播传输的OFDM(正交频分复用)信号。
