TVA metadata transporting/receiving system and method for providing TVA service in digital broadcasting environment

摘要

A system and a method for transmitting/receiving TVA(TV-Anytime) meta data are provided to transmit and receive the TVA meta data and TVA initial information together with digital broadcasting AV(Audio/Video) contents through a digital broadcasting channel to provide TVA service in a digital broadcasting environment. A TVA meta data transmitting apparatus(100) for providing TVA service in a digital broadcasting environment includes a TVA meta data encoder(120), an A/V encoder(110), and a multiplexer(130). The TVA meta data encoder encodes TVA meta data and TVA initial information initially required to provide the TVA service in the digital broadcasting environment into a TVA meta data transport stream. The A/V encoder encodes A/V contents into A/V transport streams. The multiplexer inserts the TVA meta data transport stream into the A/V transport streams to generate multiplexed transport streams and transmits the multiplexed transport streams.
