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:
An electronic device operation method according to an embodiment of the present invention comprises the steps of: acquiring an additional service and uncompressed audiovisual content information acquired through automatic contents recognition (ACR) function by a first device; outputting the incompressible audiovisual content information and the additional service through a first application including a message exchange function; receiving an execution input executing the additional service which is output through the first application; and executing the additional service according to the received execution input.
Abstract:
Provided is a companion device interoperating with a broadcast service that a broadcast reception device receives. The companion device includes: a communication unit establishing a pairing session with the broadcast reception device; and a control unit receiving device capability information from the broadcast reception device and receiving a media component that the broadcast service includes on the basis of the device capability information, wherein the device capability information signals a capability of a device necessary for presenting the media component.
Abstract:
The present invention provides a method of processing a hybrid broadcast service. The method comprises, receiving broadcast signals for the hybrid broadcast service, wherein the broadcast signals includes address information about the signaling information, transmitting a request for signaling information of the broadcast signals and receiving signaling information via a broadband channel or a mobile broadband by using one of a unicast method, a multicast method and an eMBMS (evolved Multimedia Broadcast Multicast Service) method.
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:
The receiver comprising a receiving device for receiving a data structure that encapsulates a questionnaire which represent individual questions that can be answered by the receiver, a PDI engine for acquiring the questionnaire from the data structure, receiving a setting option of a user for the application identified by the application identifier, and storing the setting option in relation to the data structure, an application signaling parser for parsing a trigger which is a signaling element to establish timing of playout of the application, and a processor for parsing a second application identifier from the trigger, acquiring the stored setting option in relation to the data structure of which a value of the first application identifier matches to a value of the second application identifier, and determining whether process the application to be launched or not based on the setting option is disclosed.
Abstract:
The present invention provides a method of transmitting broadcast signals. The method includes, receiving an uncompressed broadcast content from an external receiving unit, wherein an watermark is embedded in a frame of the uncompressed broadcast content; extracting the embedded watermark from the uncompressed broadcast content; parsing the extracted watermark; generating an URL by using information in the parsed watermark; and launching an application by using the generated URL, wherein the application provides the interactive services related to the uncompressed broadcast content.
Abstract:
Provided is a operating method of a video display device including a display unit. A receiving unit obtains an uncompressed audio and video content. A content recognition configuration management unit receives information of the uncompressed audio and video content based on a characteristic information of the uncompressed audio and video, sets a content reminder based on the information of the uncompressed audio and video content, wherein the content reminder notifies broadcasting information for another content which is related to the uncompressed audio and video content. And reminds the another content while displaying the broadcasting information of the another content based on the setting of the content reminder.
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.
