Apparatus and method for processing an interactive service

摘要

A method of processing an interactive service and an apparatus thereof are disclosed. The present invention includes receiving uncompressed audio content or uncompressed video content from an external decoding unit, extracting identifiers of frames from the received content periodically, submitting requests containing the identifiers and receiving a trigger for the content when a new segment is detected or when an event activation needs to be communicated to the receiver, 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, wherein the application parameter table includes information about at least one of applications.

主权项

1. A display device for processing an interactive service, the display device comprising:
a receiving module to receive an uncompressed audio content or an uncompressed video content from an external decoding unit; a signature extraction module to extract signatures from frames of the received content; a network interface to send the extracted signatures to an ACR (Auto Content Recognition) server, to be checked against a database of signatures of frames in order to recognize the frames represented by the signatures, wherein the frames represented by the signatures are identified by the ACR server, wherein the network interface receives a time base trigger from the ACR server, wherein the type of trigger is decided by the ACR server based on the frames represented by the signatures, wherein the time base trigger establishes a time base for activations of events, wherein the time base is synchronized with the frames, wherein the network interface retrieves an application parameter table using information in the time base trigger, wherein the application parameter table includes information about at least one of applications, wherein the information about at least one of applications include first IDs (identifiers) identifying each of the applications, and information about at least one of the events, wherein the information about at least one of the events include second IDs identifying each of the events, and information about at least one of data to be used for the corresponding event, wherein the information about at least one of data include third IDs identifying each of the data, wherein the network interface receives an activation message table along with the application parameter table,
wherein the activation message table includes activation messages for activating the events at activation times relative to the established time base,wherein each of the activation messages include first attributes, second attributes, third attributes and timing information,wherein the first attribute matches the first ID to identify the application targeted by the activation message,wherein the second attribute matches the second ID to identify the event targeted by the activation message,wherein the timing information indicates start of time period for the event targeted by the activation message, and wherein the third attribute matches the third ID to identify the data to be used for the event targeted by the activation message;a display module to output supplementary information related to the content; an user interface (UI) module to receive signal, related to the supplementary information through a remote controller; and a web browser module to receive a browser key code from the UI module and the remote controller,
wherein when the supplementary information is related to a service using a network, the browser key code is delivered to a web browser, and wherein when the supplementary information is related to a currently displayed video, signal corresponding to the currently displayed video is delivered to the display module.
