Apparatuses and methods for transmitting or receiving a broadcast content via one or more networks

A method for synchronizing multiple components delivered on a broadband network and a broadcast network in a digital receiver, the method comprising:

• receiving, by the receiver, broadband data including at least one audio component for a service via the broadband network, wherein the at least one audio component relates to a Dynamic Adaptive Streaming over HTTP (DASH) segment,
• wherein the broadband network comprises an internet network;
• receiving, by the receiver, a broadcast signal including a video component for the service, first timing information, and second timing information via the broadcast network, wherein the broadcast signal further includes a MPD (Media Presentation Description) having a DASH representation containing a segment URL for the DASH segment delivered over the broadband network;
• calculating an offset based on a receiver wall clock;
• and
• processing at least one of the at least one audio component or the video component which is time-aligned based on the calculated offset.

A digital transmitter for transmitting multiple components via a broadband network and a broadcast network, the digital transmitter comprising:

• a broadband network interface configured to transmit broadband data including at least one audio component for a service via the broadband network, wherein the at least one audio component relates to a Dynamic Adaptive Streaming over HTTP (DASH) segment,
• wherein the broadband network comprises an internet network;
• and
• a broadcast network interface configured to transmit a broadcast signal including a video component for the service, first timing information, and second timing information via the broadcast network, wherein the broadcast signal further includes a MPD (Media Presentation Description) having a DASH representation containing a segment URL for the DASH segment delivered over the broadband network.
