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.
Abstract:
Provided are a video display device and a method of operating the same. The video display device request content recognition configuration information to a third party server that is not dependent on any single channel, and receives the content recognition configuration information from the third party server. The video display device extracts a plurality of content recognition configuration information items from the content recognition configuration information and configures the plurality of content recognition configuration information item in the video display device. The video display device obtains contents information of uncompressed content on the basis of the plurality of content recognition configuration information item, obtains an application on the basis of the content information, and executes the application.
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:
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 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:
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 an interactive service and an apparatus includes generating an application parameter table including a first identifier and a second identifier, wherein the first identifier identifies a interactive programming segment which application parameter table pertains to, and wherein the second identifier identifies an application within the scope of application parameter table; generating an activation message file that indicates at least one of activation times of the applications, wherein the activation message file includes a third identifier and activation messages, wherein the third identifier matches the first identifier of application parameter table which contains the applications, wherein the activation message includes a fourth identifier and a start time information, wherein the fourth identifier matches the second identifier of the application in the application parameter table.
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 running in a second device, wherein the discovery message advertises second screen support services that the first device can provide, receiving a request for descriptions of the second screen support services from the second screen application, sending a response with the descriptions to the second screen application, providing a HTTP proxy server using a HTTP proxy server service allowing the second device to access files that are received by the first device in a broadcast stream, wherein the HTTP proxy server service is one of the second screen support services, receiving the files from the broadcast stream and delivering the files to the second device via the HTTP proxy server.
