Abstract

A method for processing a broadcast signal according to an embodiment of the present invention includes encoding data in one or more packets of a first protocol and data in one or more packets of a second protocol, wherein the one or more packets of a first protocol carry one or more service components of a first broadcast service, and a first service layer signaling information describing the first broadcast service of the one or more service components, and wherein one or more packets of a second protocol carry one or more service components of a second broadcast service, and a second service layer signaling information describing the second broadcast service of the one or more service components, the first protocol being distinct from the second protocol; processing the encoded data; and transmitting the broadcast signals carrying the processed data.

First claim

What is claimed is:

1. A method at an electronic device with one or more processors for processing broadcast signals, the method comprising:
generating data in one or more packets of a first protocol and data in one or more packets of a second protocol, wherein:
the one or more packets of the first protocol carry one or more service components of a first broadcast service, and a first service layer signaling information describing the first broadcast service of the one or more service components,
when the first protocol corresponds to ROUTE (Real-time Object delivery over Unidirectional Transport), the first service layer signaling information includes DASH (Dynamic Adaptive Streaming over HTTP) MPD (Media Presentation Description),
the one or more packets of the second protocol carry one or more service components of a second broadcast service, and a second service layer signaling information describing the second broadcast service of the one or more service components, the first protocol being distinct from the second protocol, and
when the second protocol corresponds to MMTP (MPEG Media Transport Protocol), the second service layer signaling information includes a MMT (MPEG Media Transport) package table;
processing the generated data; and
transmitting the broadcast signals carrying the processed data,
wherein the broadcast signals further includes service list information for listing the first broadcast service and the second broadcast service, and
wherein the service list information further includes bootstrap information to locate the first service signaling information and the second service signaling information.

2. The method of claim 1 , wherein at least one packet of the second protocol further carries at least one service component of the first broadcast service, and further for a receiver, the service list information is processed before the first service signaling information and the second service signaling information are processed.

3. The method of claim 2 , wherein the first service signaling information further includes access information for the at least one packet of the second protocol carrying the at least one service component of the first broadcast service.

4. A device with one or more processors for processing broadcast signals, the device comprising:
an encoder for encoding data in one or more packets of a first protocol and data in one or more packets of a second protocol, wherein;
the one or more packets of the first protocol carry one or more service components of a first broadcast service, and a first service layer signaling information describing the first broadcast service of the one or more service components,
when the first protocol corresponds to ROUTE (Real-time Object delivery over Unidirectional Transport), the first service layer signaling information includes DASH (Dynamic Adaptive Streaming over HTTP) MPD (Media Presentation Description),
the one or more packets of the second protocol carry one or more service components of a second broadcast service, and a second service layer signaling information describing the second broadcast service of the one or more service components, the first protocol being distinct from the second protocol, and
when the second protocol corresponds to MMTP (MPEG Media Transport Protocol), the second service layer signaling information includes a MMT (MPEG Media Transport) package table;
a processor for processing the encoded data; and
a transmitter for transmitting the broadcast signals carrying the processed data,
wherein the broadcast signals further includes service list information for listing the first broadcast service and the second broadcast service, and
wherein the service list information further includes bootstrap information to locate the first service signaling information and the second service signaling information.

5. The device of claim 4 , wherein at least one packet of the second protocol further carries at least one service component of the first broadcast service, and further for a receiver, the service list information is processed before the first service signaling information and the second service signaling information are processed.

6. The device of claim 5 , wherein the first service signaling information further includes access information for the at least one packet of the second protocol carrying the at least one service component of the first broadcast service.

7. A method at an electronic device with one or more processors for processing broadcast signals, the method comprising:
receiving the broadcast signals carrying one or more packets of a first protocol and data in one or more packets of a second protocol, wherein:
the one or more packets of the first protocol carry one or more service components of a first broadcast service, and a first service layer signaling information describing the first broadcast service of the one or more service components,
when the first protocol corresponds to ROUTE (Real-time Object delivery over Unidirectional Transport), the first service layer signaling information includes DASH (Dynamic Adaptive Streaming over HTTP) MPD (Media Presentation Description),
the one or more packets of the second protocol carry one or more service components of a second broadcast service, and a second service layer signaling information describing the second broadcast service of the one or more service components, the first protocol being distinct from the second protocol, and
when the second protocol corresponds to MMTP (MPEG Media Transport Protocol), the second service layer signaling information includes a MMT (MPEG Media Transport) package table;
obtaining service list information for listing the first broadcast service and the second broadcast service from the received broadcast signals, wherein the service list information further includes bootstrap information to locate the first service signaling information and the second service signaling information; and
obtaining the first service signaling information or the second service signaling information based on the service list information,
wherein the service list information is processed before the first service signaling information and the second service signaling information are processed.

8. The method of claim 7 , wherein at least one packet of the second protocol further carries at least one service component of the first broadcast service.

9. The method of claim 8 , wherein the first service signaling information further includes access information for the at least one packet of the second protocol carrying the at least one service component of the first broadcast service.

10. A device with one or more processors for processing broadcast signals, the device comprising:
a receiver for receiving the broadcast signals carrying one or more packets of a first protocol and data in one or more packets of a second protocol, wherein:
the one or more packets of the first protocol carry one or more service components of a first broadcast service, and a first service layer signaling information describing the first broadcast service of the one or more service components,
when the first protocol corresponds to ROUTE (Real-time Object delivery over Unidirectional Transport), the first service layer signaling information includes DASH (Dynamic Adaptive Streaming over HTTP) MPD (Media Presentation Description),
the one or more packets of the second protocol carry one or more service components of a second broadcast service, and a second service layer signaling information describing the second broadcast service of the one or more service components, the first protocol being distinct from the second protocol, and
when the seco
