TRANSMISSION SYSTEM FOR PROVIDING A HYBRID SERVICE CAPABLE OF PLAYING A CONTENT HAVING A LARGE SIZE WITHOUT A RESOURCE SHORTAGE, A RECEIVING DEVICE THEREOF AND A SERVICE PROVIDING METHOD THEREOF

摘要

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.;COPYRIGHT KIPO 2013;[Reference numerals] (210) First reception unit; (220) Demux unit; (230) First signal processing unit; (231) Video processing unit; (232) Audio processing unit; (240) Control unit; (250) Second reception unit; (260) Second signal processing unit; (270) Output unit
