Abstract:
The digital service signal processing apparatus according to one embodiment of the present invention, comprises: a generation module for generating a request for receiving signaling information of an application related to a program of a digital service signal using the channel information related to the program of the digital service signal; a control module for transmitting the generated request, receiving the signaling information of the application, and determining whether the application is stored using the received signaling information of the application; and a download module for downloading, if it is determined that the application is not stored, the application using the signaling information of the application.
Abstract:
The present invention relates to a method for transmitting/receiving through a network such as the Internet, and to a transmitter/receiver using same, the transmission method comprising: converting content stored in a file format into a delivery format; and including the content converted into the delivery format in a payload of an IP packet and transmitting same, wherein one or more mdats, which are included in an mdat box of the file format, are cut according to a time window and sequentially included in the delivery format in the transforming step.
Abstract:
A method of processing an interactive service and an apparatus thereof are disclosed. The present invention includes receiving uncompressed audio contents or uncompressed video contents from an external decoding unit, extracting an identifier of a frame from the received content, sending a request containing the identifier to a server and receiving a trigger for the content from the server based on the request, wherein the trigger indicates the current time of the contents and references a particular interactive event in an application parameter table or signals that the event is to be executed now or at a specified future time and the application parameter table includes information about at least one of applications.
Abstract:
A method of processing an interactive service and an apparatus thereof are disclosed. The present invention includes generating a trigger, wherein the trigger contains a first identifier and a parameter, wherein the first identifier identifies an application to be launched, wherein the parameter contains a media time stamp and a content identifier, wherein the media time stamp indicates a current point in the playout of a content, wherein the content identifier identifies the content currently being viewed, wherein the trigger is passed into the application after the application is launched, and wherein the application delivers the content identifier to a server in order to identify the content currently being viewed; generating a broadcast signal including the trigger; and transmitting the broadcast signal.
Abstract:
A method of processing a broadcast signal including an interactive broadcast service at a transmitter is disclosed. The method comprises generating an parameter table containing metadata about applications and interactive broadcast events targeted to the applications, dividing the parameter table into a plurality of parameter blocks, inserting each of the parameter blocks into each of a plurality of parameter table sections, generating a trigger which is a signaling element to identify signaling and establish timing of playout of the interactive broadcast events, inserting the trigger into a closed caption channel of the broadcast signal, transmitting the broadcast signal including the closed caption channel and a specific channel carrying the plurality of parameter table sections, wherein the trigger includes location information specifying a location of the parameter table in the broadcast signal.
Abstract:
Provided is a media content receiving method of a media content receiving device. The method includes: receiving information on a content location information file; receiving the content location information file by using the information on the content location information file; measuring a current bandwidth; requesting a first media content through a first network on the basis of the current bandwidth and the content location information file; receiving the first media content through the first network; and consuming the first media content.
Abstract:
A method of processing an interactive service and an apparatus thereof are disclosed. The present invention includes sending a discovery message to a second screen application, receiving a request for descriptions of the second screen support services, sending a response with the descriptions, receiving a trigger, and delivering the trigger to the second device using a trigger service.
Abstract:
A method of processing a digital service signal and an apparatus thereof are disclosed. The present invention includes executing a primary application for the digital service signal, wherein the primary application is a triggered application or a non-triggered application, transmitting messages of interactive services for a secondary application associated with the primary application, wherein the interactive services includes a first mode related to the triggered application or a second mode related to the non-triggered application, receiving a request for descriptions identifying the interactive services, transmitting the descriptions having service id information identifying each of the interactive services and service type information indicating a type of the each of the interactive services, and providing the interactive services by transmitting information for the interactive services.
