Abstract:
The present invention relates to a method for receiving urgent alarm contents through a broadcast system. According to an embodiment of the present invention, a method for receiving urgent alarm contents through a broadcast system includes the steps of: receiving a broadcast signal; parsing an urgent alarm table contained in the broadcast signal, the urgent alarm table containing an urgent alarm message and an urgent alarm contents transmission structure descriptor for signaling the information of the urgent alarm contents concerning the urgent alarm message, and the urgent alarm contents transmission structure descriptor containing the IP address of an IP datagram for transmitting the urgent alarm contents; receiving the IP datagram of the IP address; and decoding the IP datagram so as to reproduce the urgent alarm contents.
Abstract:
A digital broadcast receiver for receiving a broadcast signal, includes a tuner configured to receive the broadcast signal including service data in a broadcast signal and application signaling information, wherein the application signaling information includes a URL (Uniform Resource Locator) of an entry page of a broadcaster application for the digital broadcast receiver, a cache configured to store a content for the broadcaster application and a processor configured to launch the broadcaster application based on the application signaling information, wherein the entry page of the broadcaster application is loaded based on the URL, and the URL is used to point to a server.

Abstract:
A method of transmitting a broadcast signal, includes processing one or more input packets to generate one or more link layer packets, a link layer packet including a header and a payload, the header including packet type information representing a type of an input packet in the payload and payload configuration information representing a configuration of the payload, the payload configuration information representing whether the link layer packet carries a single input packet or not, wherein the type of the input packet is either an Internet Protocol (IP) packet or a Movie Picture Exports Group (MPEG) Transport Stream (TS) packet, the payload configuration information is set to 0 (zero) in response to a layer packet including a single input packet, and 1 in response to a link layer packet including more than one input packet or a segmented part of one input packet, in response to the link layer packet including the single input packet, the header includes header mode information, the header mode information is set to 0 (zero) in response to a payload length that is less than 2048 bytes, 1 in response to a payload length that is larger than 2047 bytes; processing the one or more link layer packets to generate the broadcast signal; and transmitting the broadcast signal.
Abstract:
A method for delivering data in a digital transmitter including generating service layer signaling (SLS) information comprising information for discovery and acquisition of at least one content component: generating service list table (SLT) information including bootstrap information for acquiring the SLS information; encapsulating the at least one content component, the SLS information and the SLT information via UDP/IP; and transmitting a broadcast signal comprising the at least one content component, the SLS information and the SLT information.
Abstract:
A method of processing information in a digital receiver connected to an external input source includes receiving uncompressed data of a broadcast service from the external input source, the broadcast service delivered based on either a Real-Time Object Delivery over Unidirectional Transport (ROUTE) protocol or an MPEG Media Transport (MMT) protocol; extracting an audio watermark from the uncompressed data; making a request to a specific server using domain type and server code of the audio watermark to form a first URL; receiving a recovery file including a second URL used to retrieve signaling files needed to access and present a supplementary content; retrieving the signaling files using the second URL in the recovery file; and presenting the supplementary content based on the signaling files. Further, timing information included in the recovery file is used to synchronize the supplementary content with the uncompressed data from the external input source.
Abstract:
An apparatus for receiving a broadcast signal, includes a receiver configured to receive the broadcast signal including physical layer signaling data, signaling data, content data and service guide information, wherein the signaling data is included in a signal frame indicated by the physical layer signaling data, wherein the signaling data includes mapping information between a service and a PLP, and information supporting channel scanning and service acquisition, wherein the service guide information includes a service fragment having information about the broadcast service and a content fragment having information about content data of the broadcast service, wherein the content fragment further includes a content-level PrivateExt element having component information of the content data, wherein the component information includes information for a component in the broadcast service, and wherein the component is one of a video component, an audio component, and a closed caption component (CC).
Abstract:
A method of processing a broadcast signal in a transmitter, includes generating service data, generating service layer signaling (SLS) information that provides session description information for at least one transport session carrying the service data, encapsulating the service data and the SLS information into Internet Protocol (IP) packets, generating physical layer signaling information that includes wake-up information for identifying whether a receiver is to be woken up and transmitting the broadcast signal including the IP packets and the physical layer signaling information, wherein the broadcast signal further includes emergency alert table (EAT) information that includes identification information for identifying an emergency alert message, wherein the EAT information further includes information for indicating a location of a rich media content related to the emergency alert message, and wherein the EAT information is carried in IP packets with well-known address and port information.
