Apparatuses and methods for transmitting or receiving a broadcast content via one or more networks
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 broadcast streams including first protocol packets including first portions of the broadcast content via a broadcast network, a heterogeneity network interface for receiving second protocol packets including a second portion of the broadcast content via a heterogeneity network, and a processor for configuring the broadcast content using the first protocol packets and the second protocol packets based on information included in the third protocol packets.
1. An apparatus for receiving a broadcast service, the apparatus comprising:
a broadcast network interface configured to receive a broadcast signal including first packets including a first component for the broadcast service via a broadcast network, wherein the first packets are processed based on a real time protocol;
a broadband network interface configured to receive broadband data including second packets including a second component for the broadcast service via a broadband network, wherein the second packets carry Dynamic Adaptive Streaming over HTTP (DASH) segments,
wherein the broadcast signal further includes third packets including information on the first component and the second component, wherein the third packets are received via the broadcast network,
wherein the third packets include information specifying where the second packets are delivered, and
wherein the third packets further include first timing information for the first component, and second timing information for the second component; and
a processor configured to calculate offsets based on a receiver wall clock, and present the first component and the second component which are time-aligned based on the calculated offsets.
2. The apparatus of claim 1 , wherein the third packets further include format information specifying a format of the second timing information.
3. The apparatus of claim 1 , wherein headers of the first packets include Network Time Protocol (NTP) timestamp information of the first component.
4. A method for receiving a broadcast service in a receiver, the method comprising:
receiving, by the receiver, a broadcast signal including first packets including a first component for the broadcast service via a broadcast network, wherein the first packets are processed based on a real time protocol;
receiving, by the receiver, broadband data including second packets including a second component for the broadcast service via a broadband network, wherein the second packets carry Dynamic Adaptive Streaming over HTTP (DASH) segments,
wherein the broadcast signal further includes third packets including information on the first component and the second component, wherein the third packets are received via the broadcast network,
wherein the third packets include information specifying where the second packets are delivered, and
wherein the third packets further include includes first timing information for the first component, and second timing information for the second component;
calculating offsets based on a receiver wall clock; and
presenting the first component and the second component which are time-aligned based on the calculated offsets.
5. The method of claim 4 , wherein the third packets further include format information specifying a format of the second timing information.
6. The method of claim 4 , wherein headers of the first packets include Network Time Protocol (NTP) timestamp information of the first component.
