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: The present invention relates to a mobile service and, more specifically, a method for enhancing mobile service quality when a broadcast failure or delay occurs in a wireless mobile terminal broadcast telecommunication system. A method for receiving a broadcast service according to the present invention comprises the following steps of: requesting a content server to transmit preliminary broadcast data or user customized data over a telecommunication network; receiving the requested data from the content server over a broadcast network or telecommunication network; and playing the received data when the playback of general broadcast data is delayed. According to the present invention, a broadcast video can continuously play although a broadcast failure occurs by playing a previously received video. Also, a channel delay time which a user feels can be reduced by providing user customized data.

Abstract: PURPOSE: A transmission system for providing a hybrid service, a receiving device thereof and a service providing method thereof are provided to selectively provide the hybrid service using an information describer. CONSTITUTION: A first signal processing unit (230) processes reference data detected from a demultiplexer unit. If a service is determined as a hybrid service by an information describer, a control unit (240) controls a second receiving unit to access a source device corresponding to supplementary data reference information. A second signal processing unit (260) receives a second signal including additional data from the source device through an IP communications network. The second signal processing unit processes the additional data. An output unit (270) synchronizes the reference data processed in the first signal processing unit and the additional data processed in the second signal processing unit and outputs synchronized data of the reference data and the additional data.
