Abstract: The present invention relates to a flexible MMT packet transmitting method of multiplex layer media data. The flexible MMT packet transmitting method includes the following steps of: generating an MMT asset by performing a capsulation based on a media processing unit (MPU) which is generated based on a media access unit (AU); generating an MMT composition information (MMT-CI) on the MMT asset; generating an MMT packet by packetizing the MMT asset and the MMT-CI; and transmitting the generated MMT packet to a receiving side. The MMT-CI includes dependency information of at least another MMT asset which is different from the MMT asset. According to the present invention, the reception and transmission of multiplex layer media data are able to notify whether an MMT asset is dependent on another MMT asset and supports a smooth decoding of the MMT asset when providing a hybrid transmission-based MMT service.
Abstract translation: 本发明涉及复用层媒体数据的灵活的MMT分组发送方法。 灵活的MMT分组发送方法包括以下步骤：通过基于基于媒体访问单元（AU）生成的媒体处理单元（MPU）执行封装来生成MMT资源; 在MMT资产上生成MMT组合信息（MMT-CI）; 通过分组MMT资产和MMT-CI来生成MMT分组; 以及将生成的MMT分组发送到接收侧。 MMT-CI包括与MMT资产不同的至少另一MMT资产的依赖性信息。 根据本发明，复用层媒体数据的接收和发送能够通知MMT资产是否依赖于另一MMT资产，并且在提供基于混合发送的MMT业务时支持MMT资产的平滑解码。

Abstract: A transmitter combines a first phase modulation signal for first input data and a second phase modulation signal for second input data by using a first combination method and transmits the combined signal, and a receiver receives the combined signal. The receiver extracts another combined signal, in which the first phase modulation signal and the second phase modulation signal are combined with a second combination method, from the received signal, separates the first and the second phase modulation signal from the received signal based on the received signal and the extracted signal, obtains the first input data by demodulating the first phase modulation signal and the second input data by demodulating the second phase modulation signal.

Abstract: PURPOSE: A method for processing requests/demands for a seamless and high definition service in multimedia communication and a device thereof are provided to guarantee the best performance while efficiently using communication resources. CONSTITUTION: A bearer is added to a basically set bearer to improve the definition degradation and seams of a real time high definition 3D video. A frame rate of a source is reduced in half by separating an odd frame and an even frame. Each stream is separately coded. Therefore, the source is coded with different descriptions. Information is transceived through a DDC(Double Description Coding) technique. [Reference numerals] (AA) 30 fps, 15 fps are examples; (BB) Control according to a Error Event in the unit of GOP

Abstract: PURPOSE: A cooperative multipoint transmission and reception method and system thereof are provided to maximize resource usage efficiency by allocating resources for cooperative multipoint transmission. CONSTITUTION: Each transmission point exchanges information for executing cooperative multipoint transmission with one or more other points which participate in the cooperative multipoint transmission(S220). Each transmission point allocates resources based on the resource allocation information of the other transmission points without overlapping with allocated resources of other transmission points(S230). The terminal executes the cooperative multipoint transmission by using the allocated resources(S240).
Abstract translation: 目的：提供协同多点发送和接收方法及其系统，以通过分配资源来协调多点传输来最大化资源使用效率。 构成：每个发送点与参与协作多点传输的一个或多个其他点交换用于执行协作多点传输的信息（S220）。 每个传输点基于其他传输点的资源分配信息分配资源，而不与其他传输点的分配资源重叠（S230）。 终端通过使用分配的资源来执行协作多点传输（S240）。
