Abstract:
A method of transmitting a broadcast signal is proposed. In the method of transmitting the broadcast signal, a system capable of supporting future broadcast services in an environment supporting future hybrid broadcast using terrestrial broadcast networks and the Internet is proposed. In addition, efficient signaling methods using both terrestrial broadcast networks and the Internet in an environment supporting future hybrid broadcast is proposed.
Abstract:
The present invention provides a method for transmitting a broadcast signal. The method for transmitting a broadcast signal according to one embodiment of the present invention comprises: a step for generating service guide information, including access information of a broadcast service, and content data, wherein the service guide information includes a service fragment indicating the information on the broadcast service, a content fragment indicating the information on the content data, and/or a component fragment indicating the information on components included in the broadcast service; a step for encoding the generated service guide information and the content data; and a step for transmitting the encoded service guide information and the content data.
Abstract:
An apparatus for processing a hybrid broadcast service, the apparatus comprising a reception module for receiving broadcast signals though a broadcast channel or contents through a broadband channel for the hybrid broadcast service, wherein the broadcast signals include data for the hybrid broadcast service and an EAM (Emergency Alert message) and a processor for receiving a request from a companion device and sending at least one of a content or continuous components or files or data or media or the data are a part of the hybrid broadcast service which is currently selected.
Abstract:
The present invention relates to a method for managing a connection between a first device and a second device in a network. The method may include requesting application information to the second device, the application information including information related to a specific application included in the second device for an interactive service, obtaining the information related to the specific application from the second device in response to the request, and performing the connection between the first device and the second device based on the information related to the specific application.
Abstract:
The present specification relates to a method for establishing, by a first device, a device-to-device connection in a wireless communication system, the method comprising the steps of: transmitting, to at least one second device, a first communication signal including connection information for a second communication connection; receiving a response to an infrared signal from the at least one second device; and establishing a second communication connection with the second device on the basis of the received response.
Abstract:
A method of accessing a supplementary content in a digital broadcast receiver connected to an external input source, the method including receiving uncompressed data of a broadcast service from the external input source, the broadcast service being delivered based on either a Real-Time Object Delivery over Unidirectional Transport (ROUTE) protocol or an MPEG Media Transport (MMT) protocol, wherein the uncompressed data includes at least one of audio data or video data, extracting at least one watermark from the uncompressed data, making a request to a server, receiving a recovery file including an URL (Uniform Resource Locator) used to retrieve signaling files needed to access and present the supplementary content, wherein the recovery file further includes an identifier of a broadcast stream, a major channel number, a minor channel number, service ID for uniquely identifying the broadcast service within a scope of a broadcast area, and version of service information, retrieving the signaling files using the URL included in the recovery file, and presenting the supplementary content based on the signaling files, wherein timing information included in the recovery file is used to synchronize the supplementary content with the uncompressed data from the external input source.
Abstract:
Disclosed in various embodiments are a method by which a first device transmits a collective perception message (CPM) in a wireless communication system, and a device therefor. Disclosed are a method by which a first device transmits a collective perception message (CPM) in a wireless communication system, and a device therefor, the method comprising the steps of: receiving a first message from a second device; acquiring sensing information about adjacent objects; and transmitting the CPM on the basis of the sensing information, wherein the first device determines whether object information that overlaps with first object information acquired from the first message is included in the sensing information, and determines whether to include the overlapping object information in the CPM on the basis of the distance to the second device.
