TRANSMITTING DEVICE, A RECEIVING DEVICE THEREOF, AND A TRANSCEIVING METHOD THEREOF CAPABLE OF PROVIDING NEW CONTENT TO A USER EVEN IF DATA CANNOT BE RECEIVED THROUGH A SECOND TRANSMITTING NETWORK OR THE SECOND TRANSMITTING NETWORK IS IN A BAD STATE

摘要

PURPOSE: A transmitting device, a receiving device thereof, and a transceiving method thereof are provided to supply new content to a user by overcoming a transmission bandwidth limit by transceiving different data through different paths with existing facilities.;CONSTITUTION: A down scaler(111) performs the down scaling of multimedia data. A first encoder(112) encodes the scaled multimedia data. A first transmitting unit(120) transmits the encoded multimedia data through a first transmission network. A decoder(113) decodes the encoded multimedia data. An up scaler performs the up scaling of the decoded multimedia data. A restoration data generating unit(115) generates restoration data by using the multimedia data. A second encoder(116) encodes the restoration data. A second transmitting unit(130) transmits the encoded restoration data through a second transmission network.;COPYRIGHT KIPO 2013;[Reference numerals] (111) Down scaler; (112) First encoder; (113) Decoder; (114) Up scaler; (115) Restoration data generating unit; (116) Second encoder; (120) First transmitting unit; (130) Second transmitting unit; (AA,BB) Multimedia data
