    • PURPOSE: An image processing device and a method thereof are provided to supply a stereoscopic video service while maintaining transmission capacity of video data small and generating and displaying stereoscopic video by using additional data and a reference data transmitted in non real time. CONSTITUTION: An image processing apparatus comprises as follows. A storing unit stores the first video data. An identification unit(110) determines whether the first time point video data is stored in the storing unit or not if the second time point video data is received. A processing unit(130) generates a stereoscopic video by combining the first time point video data and the second time point video data if the first time point video data is stored in the storing unit.
    • 目的:提供一种图像处理装置及其方法,用于提供立体视频服务,同时保持视频数据的传输容量小,并通过使用附加数据和非实时传输的参考数据来生成和显示立体视频。 构成:图像处理装置如下。 存储单元存储第一视频数据。 如果接收到第二时间点视频数据,则识别单元(110)确定第一时间点视频数据是否存储在存储单元中。 如果第一时间点视频数据被存储在存储单元中,处理单元(130)通过组合第一时间点视频数据和第二时间点视频数据来产生立体视频。

    • PURPOSE: A transmission and reception method in a digital multimedia broadcasting system and an apparatus thereof are provided to divide one transmission stream into a plurality of streams in consideration of effective data rate in enhancement layer and effective data transmission rate in essential layer and transmit the transmission stream, thereby performing divided transmission of the transmission stream adaptively according to transmission environment. CONSTITUTION: An enhanced layer processor(12) comprises an enhanced layer multiplexer(121), a stream dividing unit(122) and an enhanced layer channel encoder(123). The enhanced layer multiplexer outputs an enhanced layer TS(Transport Stream) by multiplexing of base streams of the enhancement layer. The stream dividing unit divides the enhancement layer transport stream into a plurality of streams. The enhanced layer channel encoder performs channel encoding of divided enhanced layer TS.
    • 目的:提供数字多媒体广播系统中的发送和接收方法及其装置,以考虑增强层中的有效数据速率和基本层中的有效数据传输速率将一个传输流分成多个流,并传输传输 流,从而根据传输环境自适应地执行传输流的划分传输。 构成:增强层处理器(12)包括增强层多路复用器(121),流分割单元(122)和增强层信道编码器(123)。 增强层多路复用器通过复用增强层的基本流来输出增强层TS(传输流)。 流分割单元将增强层传输流分成多个流。 增强层信道编码器执行分割增强层TS的信道编码。

    • A method for transmitting and receiving a broadcasting signal is provided to request high efficient transmission while making compatibility with an existing digital broadcasting signal possible, thereby providing a high quality service. A video signal of a broadcasting signal is layered into a basic layer video elementary stream and an enhanced layer video elementary stream. The basic layer video elementary stream and the enhanced layer video elementary stream are packetized into a basic layer video packet and an enhanced layer video packet. A basic layer transmission stream is generated by multiplexing the basic layer video packet with a basic layer audio packet. The basic layer transmission stream and the enhanced layer video packet are transmitted.
    • 提供一种用于发送和接收广播信号的方法,以便在与现有数字广播信号可能的兼容的同时请求高效率的传输,从而提供高质量的服务。 广播信号的视频信号被分层为基本层视频基本流和增强层视频基本流。 基本层视频基本流和增强层视频基本流被打包成基础层视频分组和增强层视频分组。 基本层传输流是通过将基本层视频包与基本层音频包复用而生成的。 基本层传输流和增强层视频分组被传输。
