TRANSCEIVING DEVICE FOR 3DTV BROADCASTING AND A CONTROL METHOD THEREOF CAPABLE OF REMOVING A DELAY CAUSED BY DOWNLOAD TIME BY TRANSMITTING ADDITIONAL CONTENT FOR A 3D SERVICE

摘要

PURPOSE: A transceiving device for 3DTV broadcasting and a control method thereof are provided to supply a 3D service according to a request of a user by transmitting data additionally required for an existing AV program through a bidirectional communication network.;CONSTITUTION: Additional content generated in a content server(201) is encoded in an additional content encoder(207). A metadata generating unit(208) generates metadata. A multiplexing and streaming generating unit(209) multiplexes the encoded additional content and the metadata and converts the multiplexed data into streaming information. A protocol processing unit(210) packetizes the converted information to transmit the packetized information to a bidirectional communication network(211).;COPYRIGHT KIPO 2013;[Reference numerals] (201) Content server; (202) Basic content encoder; (203) Signaling information and metadata generating unit; (204) Broadcast stream multiplexing unit; (205,206) Transmitting unit; (207) Additional content encoder; (208) Metadata generating unit; (209) Multiplexing and streaming generating unit; (210) Protocol processing unit; (211) Bidirectional communication network; (AA) Access information for additional content; (BB,EE) Content connecting playing information; (CC) Basic content; (DD) Access information for the basic content
