    • Disclosed are methods of transmitting and receiving media information file for HTTP stream. Content is divided into segments, the segments are divided into segment sub groups, each of the divided segments grouping the segment sub groups, a meta media information file including information on a segment sub group is configured; and sub media information file including information on segments in a segment sub group is configured. When service initializes, the metal media information file is transmitted. When a transmission request for content is received, the sub media information file to which a playback request timing for content belongs is selected and transmitted by referring to the meta media information file, and then, a segment in a segment sub group corresponding to the sub media information file is transmitted. Thus, during HTTP streaming, initial transmission delay is reduced, and random access and trick mode playback are possible.
    • 公开了发送和接收HTTP流的媒体信息文件的方法。 内容被分割成段,将段划分成段子组,分割段对每个段子组进行分组,构成包含关于段子组的信息的元媒体信息文件; 并且配置包括关于段子组中的段的信息的子媒体信息文件。 当服务初始化时,传送金属媒体信息文件。 当接收到对内容的发送请求时,通过参考元媒体信息文件来选择和发送用于内容所属的重放请求定时的子媒体信息文件,然后,对应于子媒体信息文件的片段子组中的片段 传输媒体信息文件。 因此,在HTTP流传输期间,初始传输延迟减少,并且随机访问和特技模式播放是可能的。

    • Disclosed are cross-layer optimization method where information about lots of dynamic changes in wireless environment is shared and cross-layer optimization is implemented and abstraction layer component. Multimedia transmission layer operating method where optimization of first layer and second layer is implemented by using service information provided from first layer having transmission layer and network layer and second layer lower than datalink layer. The operating method includes upward abstraction step where service information provided to second layer is processed and processed service information is provided to multimedia transmission layer and downward abstraction step where indication information provided from multimedia transmission layer is processed and processed service information is provided to second layer. Consequently, there is advantage that all layers share diverse information about lots of dynamic changes in wireless environment, and the diverse information can be controlled to allow transmission where QoS is ensured more effectively.
    • 披露了跨层优化方法,其中关于无线环境中的大量动态变化的信息被共享并且跨层优化被实现和抽象层组件。 通过使用从具有传输层和网络层的第一层提供的服务信息以及比数据链路层低的第二层来实现第一层和第二层的优化的多媒体传输层操作方法。 操作方法包括向第二层提供服务信息进行处理和处理的向上抽象步骤,向多媒体传输层提供服务信息,并向下抽象步骤提供从多媒体传输层提供的指示信息处理和处理的服务信息提供给第二层。 因此,有利的是,所有层都共享关于无线环境中的许多动态变化的不同信息,并且可以控制各种信息以允许更有效地确保QoS的传输。

    • Disclosed is a processing method which enables natural reproduction in the event an expression switch occurs during an HTTP streaming transmission. The method involves: receiving a first media information file which stores information regarding segments in the event no expression switch occurs, and a second media information file which stores information regarding segments in the event an expression switch occurs; and receiving and reproducing segments of the content to be received with reference to the first information in the event no expression switch occurs, and receiving and reproducing segments of the content to be received with reference to the second information in the event an expression switch occurs. Thus, multimedia content may be provided without screen stoppage errors arising from changes in the dynamic environment of a channel.
    • 公开了一种在HTTP流传输期间发生表达式切换的情况下能够进行自然再现的处理方法。 该方法包括:接收第一媒体信息文件,该第一媒体信息文件存储关于在没有表达式切换的情况下的片段的信息;以及第二媒体信息文件,其存储关于发生表达式切换的事件的片段的信息; 以及在没有表达式切换的情况下,参照第一信息接收和再现要接收的内容的段,以及在发生表达式切换的情况下,参考第二信息来接收和再现要接收的内容的段。 因此,可以提供多媒体内容而没有由频道的动态环境的变化引起的屏幕停止错误。

    • Discussed is a processing method which enables natural reproduction upon the occurrence of representation switching during the transmission of an HTTP stream. The method includes: constructing, for a first representation, a plurality of segments including base layer of scalable video coding, constructing, for a second representation with a higher resolution than the first representation, a plurality of segments including enhanced layer of scalable video coding, and transmitting at least one of at least a part of the plurality of segments for the first representation and at least a part of the plurality of segments for the second representation, when transmitting the second representation. Only base layers may be extracted from the second representation and used as a reference in decoding low bit-rate segments to be reproduced in the future, thus multimedia content can be seamlessly displayed upon the occurrence of representation-switching.
    • 讨论了一种处理方法,其在HTTP流的发送期间发生表示切换时能够进行自然再现。 该方法包括:为第一表示构建包括可分级视频编码的基本层的多个段,为具有比第一表示更高分辨率的第二表示构建包括增强层的可分级视频编码的多个段, 以及当发送所述第二表示时,发送用于所述第一表示的所述多个段的至少一部分中的至少一个和用于所述第二表示的所述多个段中的至少一部分。 可以仅从第二表示中提取基本层,并将其用作解码将来要再现的低比特率段的参考,从而可以在表示切换发生时无缝地显示多媒体内容。
