Apparatuses for providing and receiving augmented broadcasting service in hybrid broadcasting environment

An apparatus for providing an augmented broadcasting service, comprising:

• a real-time data provider configured to provide real-time data through a first transmission network;
• an augmented content provider configured to provide augmented content through a second transmission network, wherein the augmented content is synchronized with the real-time data;
• an augmented broadcasting descriptor generator circuit that generates an augmented broadcasting descriptor that determines whether an augmented broadcasting service receiving apparatus receives a transport stream, and input the generated augmented broadcasting descriptor to a multiplexer,
• wherein the multiplexer includes a first multiplexer and a second multiplexer in which the second multiplexer receives the generated augmented broadcasting descriptor;
• and
• the multiplexer configured to multiplex the real-time data, augmented content metadata and timing information for synchronization between the real-time data and the augmented content metadata, and output resulting data,
• wherein the multiplexer comprises the first multiplexer configured to multiplex a real-time transport stream, and the second multiplexer configured to re-multiplex the multiplexed real-time transport stream along with program initialization information as information for synchronization between augmented content metadata and a network, and output a resulting real-time transport stream,
• wherein the second multiplexer distinguishes between section packets and inserts the augmented broadcasting descriptor into a table of a section packet, and
• wherein the augmented broadcasting descriptor includes:
• a descriptor tag including information for identifying an associated descriptor as an augmented broadcast descriptor;
• a descriptor length including information on a total length of the augmented broadcasting descriptor;
• an augmented broadcasting service type including information on a type of augmented broadcasting service, and
• a metadata generator circuit configured to, in response to a start signal from the second multiplexer, generate augmented content metadata containing XML data having augmented content activation time information with reference to a program start point, or containing both an initial program clock reference and a transport stream to contain XML, and input resulting augmented content metadata to the second multiplexer.
