TRANSMISSION APPARATUS AND METHOD, AND RECEPTION APPARATUS AND METHOD FOR PROVIDING PROGRAM ASSOCIATED STEREOSCOPIC BROADCASTING SERVICE

摘要

PURPOSE: A transmission device for providing a stereoscopic broadcasting service of a program linkage type and a method and a reception device and a method thereof are provided to enable a reference picture to use a 2DTV system, and to deliver an additional picture based on an advanced television systems committee and a network resource table transmission mechanism in non real time, thereby overcoming a limit of a 3D band width and supplying compatibility with a existing 2D broadcasting system. CONSTITUTION: A real time stream encoder(210) generates a real time stream by encoding a reference picture. A non real time stream encoder(230) generates a non real time stream based on an additional picture. A picture synchronization information generator(220) generates a picture synchronization information stream and service signaling for synchronization of the reference picture and the additional picture. A re-multiplexer(240) generates a stereoscopic broadcasting stream of a program linkage type.
