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

摘要

An apparatus for providing an augmented broadcasting service and an apparatus for receiving the augmented broadcasting service in a hybrid broadcasting environment. The apparatus for providing the augmented broadcasting service includes: 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 to be synchronized with the real-time data; and a multiplexer configured to multiplex the real-time data, the augmented content metadata and timing information for synchronization between the real-time data and the augmented content metadata, and output resulting data.

1. 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.
