Abstract:
The present invention provides an apparatus for processing at least one PDU (protocol data unit) in an N layer in a transmitting side of a broadcast system, the apparatus comprising a PDU processor for receiving at least one higher (N+1) layer PDU and generating a PDU including the received at least one higher (N+1) layer PDU and a PDU post-processor for post processing the generated PDU and transmitting the post-processed PDU to a lower (N−1) layer.
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 digital service signals includes a PDI module configured to receive a PDI table, wherein the PDI table includes at least one question element having an id field identifying a PDI question and extract the PDI question from the PDI table, a PDI storing module configured to receive a PDI answer according to the extracted PDI question, a filtering module configured to receive a filtering criteria information associated with downloadable contents including criterion id and criterion value, wherein the criterion id identifies each criterion matching the id field of each of the PDI question and the criterion value indicates a value of the criterion being a possible answer to the PDI question and filter contents of the digital service signal using the filtering criteria information to determine the contents to download.
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:
Disclosed are a signal transmitting method, a signal transmitting apparatus, and a system for transmitting and receiving a signal. The signal transmitting method comprises the steps of: discovering a companion device using a multicast mode; receiving and storing device type information from the discovered companion device; receiving an application uniform resource identifier (URI) and storing the application URI to correspond to the device type information; and identifying the device type information of the companion device selected by a user and transmitting to the selected companion device the application URI corresponding to the device type information.
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:
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 sending a discovery message to a second screen application running in a second device, wherein the discovery message advertises second screen support services that the first device can provide, receiving a request for descriptions of the second screen support services from the second screen application, sending a response with the descriptions to the second screen application, providing a HTTP proxy server using a HTTP proxy server service allowing the second device to access files that are received by the first device in a broadcast stream, wherein the HTTP proxy server service is one of the second screen support services, receiving the files from the broadcast stream and delivering the files to the second device via the HTTP proxy server.
Abstract:
A method of processing an interactive service and an apparatus includes generating an application parameter table including a first identifier and a second identifier, wherein the first identifier identifies a interactive programming segment which application parameter table pertains to, and wherein the second identifier identifies an application within the scope of application parameter table; generating an activation message file that indicates at least one of activation times of the applications, wherein the activation message file includes a third identifier and activation messages, wherein the third identifier matches the first identifier of application parameter table which contains the applications, wherein the activation message includes a fourth identifier and a start time information, wherein the fourth identifier matches the second identifier of the application in the application parameter table.
