PRIORITY

This application is a National Phase Entry of PCT International Application No. PCT/KR2016/004022, which was filed on Apr. 18, 2016, and claims priorities to KR Patent Application Nos. 10-2015-0054719 filed on Apr. 17, 2015, 10-2015-0058107 filed on Apr. 24, 2015 and 10-2015-0107526 filed on Jul. 29, 2015, the contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to a method and apparatus for providing service signaling related to contents forming a broadcasting service.

BACKGROUND ART

A digital broadcasting service transmits not only various types of multimedia contents to be provided to users, but also meta information needed during selection, reception, and playback of the multimedia contents, that is, signaling information. The signaling information is roughly divided into service acquisition information and service announcement information. The service acquisition information includes information needed for reception and playback of a broadcasting service, for example, media component information forming the service, decoder configuration information needed for reception and playback of the media component information, etc. The service announcement information is information a user may use when selecting a broadcasting service, and is used to provide richer information. For example, program schedule information, additional service information related to a service, and so forth may be provided. A receiver selects a broadcasting service based on the service announcement information, obtains the service acquisition information related to the broadcasting service through a broadcasting signal, and finally provides the broadcasting service to a user.

Thus, a need exists for a scheme for efficiently providing and processing signaling information delivered to a user to receive and play a digital broadcasting service.

DETAILED DESCRIPTION OF THE INVENTION

Technical Problem

The present disclosure provides a method and apparatus for efficiently providing service signaling related to contents forming a broadcasting service.

The present disclosure also provides a method and apparatus for delivering signaling provided by a broadcasting service through a predetermined transmission scheme and at least one transport protocol in a broadcasting system using the at least one transport protocol.

Moreover, the present disclosure provides a method and apparatus for supporting a table structure for transmitting signaling needed for reception and play of a broadcasting service selected by a receiver.

Technical Solution

A method for transmitting service signaling for a broadcasting service according to an embodiment of the present disclosure includes generating a first packet stream including first media data according to a first transport protocol, generating a second packet stream including second media data according to a second transport protocol, generating a user service description (USD) including service signaling related to at least one of the first packet stream and the second packet stream, and transmitting the first packet stream, the second packet stream, and the USD.

A method for receiving service signaling for a broadcasting service according to an embodiment of the present disclosure includes receiving a broadcasting signal, extracting, from the broadcasting signal, a first packet stream including first media data according to a first transport protocol, a second packet stream including second media data according to a second transport protocol, and a USD including service signaling related to at least one of the first packet stream and the second packet stream, and decoding at least one of the first packet stream and the second packet stream by using the USD.

An apparatus for transmitting service signaling for a broadcasting service according to an embodiment of the present disclosure includes a processing unit configured to generate a first packet stream including first media data according to a first transport protocol, to generate a second packet stream including second media data according to a second transport protocol, to generate a USD including service signaling related to at least one of the first packet stream and the second packet stream, and a transmission unit configured to transmit the first packet stream, the second packet stream, and the USD.

An apparatus for receiving service signaling for a broadcasting service according to an embodiment of the present disclosure includes a reception unit configured to receive a broadcasting signal and a processing unit configured to extract, from the broadcasting signal, a first packet stream including first media data according to a first transport protocol, a second packet stream including second media data according to a second transport protocol, and a USD including service signaling related to at least one of the first packet stream and the second packet stream, and to decode at least one of the first packet stream and the second packet stream by using the USD.
