Abstract:
The present invention provides a method of providing interactive services or contents. The method includes, receiving a ESG (Enhancement Service Guide) information including preference criteria indicating characteristics of the interactive services or contents for recommending the user the interactive services or contents based on user's personal interests, receiving a PDI (Profiles, Demographics, Interests) table via broadcast signals, wherein the PDI table includes plural PDI questions related to user's personal interests for interactive contents, wherein each of the PDI questions has a question ID identifying a PDI question, obtaining an answer for at least one of the PDI questions, storing the obtained answer in the PDI table, determining recommendation interactive services or contents by comparing the preference criteria with the obtained answer and presenting the determined recommendation interactive services or contents in ESG.
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:
An apparatus of processing a digital service signals and a method thereof are disclosed. The present invention includes a receiving module configured to receive the digital service signals having contents and receive URL information for additional data related to the contents, an extracting module configured to extract logo data for indicating contents provider from each of the video frames of the contents, wherein the logo data is located in a specific area in the each of the video frames, a comparing module configured to compare the extracted logo data with stored logo data to obtain channel information of the contents, an obtaining module configured to obtain the channel information of the contents from metadata related to the logo data and obtain the additional data related to the contents and a generating module configured to generate a request for obtaining the URL information using the obtained channel information, wherein the receiving module receives the URL information using the generated request, wherein the obtaining module obtains the additional data over an IP (Internet Protocol network) according to the URL information.
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 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.
