Abstract

Disclosed herein are a signaling method for broadcast network-based radio/audio services and an apparatus for the same. The signaling method is performed by a transmission apparatus for providing radio/audio services based on a broadcast network, and includes generating an Internet Protocol (IP) packet by encapsulating digital radio/audio content data using Multiplex Distribution Interface (MDI)/Distribution and Communications Protocol (DCP), and generating Service Layer Signaling (SLS) data by modulating the IP packet into an ALP packet, generating a Service List Table (SLT) to set a service protocol signaling value corresponding to the MDI/DCP and generating Low Layer Signaling (LLS) data including the SLT, and transmitting the LLS data and the SLS data.

First claim

What is claimed is:

1 . A signaling method performed by a transmission apparatus for providing radio/audio services based on a broadcast network, the signaling method comprising:
generating an Internet Protocol (IP) packet by encapsulating digital radio/audio content data using Multiplex Distribution Interface (MDI)/Distribution and Communications Protocol (DCP), and generating Service Layer Signaling (SLS) data by modulating the IP packet into an ALP packet; generating a Service List Table (SLT) to set a service protocol signaling value corresponding to the MDI/DCP and generating Low Layer Signaling (LLS) data including the SLT; and transmitting the LLS data and the SLS data.

2 . The signaling method of claim 1 , wherein a signaling value corresponding to the MDI/DCP is defined in the SLT.

3 . The signaling method of claim 2 , wherein generating the LLS data comprises:
inputting the signaling value defined to correspond to the MDI/DCP to a service protocol field in the SLT.

4 . The signaling method of claim 1 , wherein the IP packet is transmitted in accordance with an IPv4 packet or a compressed IP packet.

5 . The signaling method of claim 1 , wherein transmitting the LLS data and the SLS data comprises:
setting service IDs of a Fast Access Channel (FAC) and a Service Description Channel (SDC) that provide service attribute information in a transmission frame to a service ID of the LLS data.

6 . The signaling method of claim 5 , wherein transmitting the LLS data and the SLS data further comprises:
transmitting the FAC through a first Physical Layer Pipe (PLP) and transmitting the SDC through a second PLP, wherein the first PLP is set to a channel encoding mode with reception stability higher than that of the second PLP.

7 . A transmission apparatus for providing radio/audio services based on a broadcast network, comprising:
a protocol stack comprising: an application layer configured to manage digital radio/audio content data; a transport layer configured to generate an IP packet by encapsulating the digital radio/audio content data using Multiplex Distribution Interface (MDI)/Distribution and Communications Protocol (DCP); a network layer configured to perform routing control on the IP packet; a link layer configured to modulate the IP packet into an ALP packet; and a physical layer configured to transmit the ALP packet, wherein the link layer generates a Service List Table (SLT) to set a service protocol signaling value corresponding to the MDI/DCP, and generates Low Layer Signaling (LLS) data including the SLT.

8 . The transmission apparatus of claim 7 , wherein a signaling value corresponding to the MDI/DCP is defined in the SLT.

9 . The transmission apparatus of claim 8 , wherein the signaling value defined to correspond to the MDI/DCP is input to a service protocol field in the SLT.

10 . The transmission apparatus of claim 7 , wherein the IP packet is transmitted in accordance with an IPV4 packet or a compressed IP packet.

11 . The transmission apparatus of claim 7 , wherein service IDs of a Fast Access Channel (FAC) and a Service Description Channel (SDC) that provide service attribute information in a transmission frame are set to a service ID of the LLS data.

12 . The transmission apparatus of claim 11 , wherein the FAC is transmitted through a first Physical Layer Pipe (PLP) and the SDC is transmitted through a second PLP, wherein the first PLP is set to a channel encoding mode with reception stability higher than that of the second PLP.

13 . A transmission apparatus for providing radio/audio services based on a broadcast network, comprising:
a protocol stack comprising: an application layer configured to manage digital radio/audio content data; a transport layer configured to encapsulate the digital radio/audio content data using Multiplex Distribution Interface (MDI)/Distribution and Communications Protocol (DCP); a link layer configured to convert the encapsulated digital radio/audio content data into an ALP packet; and a physical layer configured to transmit the ALP packet, wherein the ALP packet is transmitted in accordance with packet type extension.
