    Abstract: The present invention relates to an apparatus for supporting hybrid broadcasting in a digital broadcasting system. The present invention provides an apparatus for receiving a broadcast content via one or more networks. The apparatus comprises a broadcast network interface for receiving a broadcast stream including a first portion of the broadcast content via a broadcast network; a heterogeneous network interface for receiving a heterogeneous stream including a second portion of the broadcast content via a heterogeneous network; and wherein the broadcast stream further includes timeline reference signaling information containing metadata for synchronizing streams transmitted via the one or more networks, and wherein the timeline reference signaling information includes at least one timeline reference information reconstituting timeline of at least one of the broadcast stream and the heterogeneous stream, a processor for configuring the broadcast content using the broadcast stream and the heterogeneous stream based on the timeline reference signaling information. The present invention is effective in easily synchronizing transport streams transmitted through each of heterogeneous networks.
