Abstract:
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.
Abstract:
A broadcasting signal reception device may include a reception unit for receiving, through the broadcasting network, a broadcasting signal including a first component of a DASH content which can be received through a broadcasting network and a broadband network; a delivery module for de-capsulating the received broadcasting signal, outputting LCT packets transmitted through one or more LCT channels, and parsing signaling information used for acquiring segments corresponding to the first component of the DASH content included in the LCT packets; and a decoder for decoding the acquired segments.
Abstract:
One embodiment of the present invention provides a method and a device for transmitting and receiving service guide information. The service guide information transmission method, according to one embodiment of the present invention, comprises the steps of: generating service guide information including information on broadcast service and content; encoding the generated service guide information; and transmitting the encoded service guide information.
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:
A broadcast receiving apparatus may comprise: a broadcast interface for receiving a broadcast signal comprising an emergency alert message and signaling information indicating metadata for the emergency alert message; a control unit for generating an emergency alert multicast message comprising attributes of the emergency alert message on the basis of the broadcast signal; and a companion screen interface for transferring the emergency alert multicast message to at least one companion screen device in a multicast mode.
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.
