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 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:
An apparatus for processing digital service signals includes a receiving module configured to receive contents having watermarks, where the watermarks are inserted in audio or video frames of the contents, the watermarks carry channel information related to the contents, and content information having URL information for additional data of the contents. An extracting module is configured to extract the watermarks from the audio or video frames, and an obtaining module is configured to obtain the additional data over an IP (Internet Protocol) network using the extracted watermarks.

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:
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:
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 for transmitting a broadcast signal by a transmitter includes generating first service data, and second service data; generating service signaling data including an extended User Service Description (USD); encoding the first service data, the second service data, and the service signaling data; time interleaving the first service data, and the second service data, and the service signaling data in a memory based on one or more virtual position information; frequency interleaving the first service data, the second service data, and the service signaling data based on an interleaving sequence that is generated by checking a sequence that is generated based on an offset and a bit sequence; and transmitting the service signaling data, the first service data and the second service data.
