Abstract:
The present invention relates to a signal transceiving apparatus and a signal transceiving method. One embodiment of the present invention provides a signal transceiving method comprising: a step of generating HD video from UHD video and obtaining residual data of the UHD video, remaining after converting the HD video from the UHD video; and a step of transmitting the converted HD video to a base layer stream and the residual data to an enhancement layer stream.
Abstract:
A video display device is provided. A receiving unit obtains an uncompressed audio and video content. A display unit displays the uncompressed audio and video content. A content recognition configuration management unit extracts a first characteristic information corresponding to a first characteristic information type from the uncompressed audio and video content, receives a first response to a first query which includes the first characteristic information, determines a second characteristic information type based on the first response, extracts a second characteristic information corresponding to the second characteristic information type from the uncompressed audio and video content, and receives a second response to a second query which includes the second characteristic information.
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 method of processing an interactive service and an apparatus thereof are disclosed. The present invention includes generating an application parameter table which includes information about at least one of applications, wherein the application parameter table includes 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, and wherein the start time information indicates the start time for an event targeted to the application relative to segment time; generating a multi-part message with the application parameter table as the first part and the activation message file as the second part; and transmitting the multi-part message to receiver via HTTP.
Abstract:
Provided are a video display device and a method of operating the same. The method includes: executing an enhanced service playing application not dependent on any single channel; obtaining an uncompressed audio video (AV) content; playing the uncompressed AV content through the display unit; attempting to obtain contents information on the uncompressed AV content on the basis of a part of the uncompressed AV content; transmitting an enhanced service request message to an enhanced service providing server not dependent on any single channel by the enhanced service; receiving an enhanced service from the enhanced service providing server; and playing the enhanced service through the display unit by the enhanced service playing application.
Abstract:
Disclosed is coated paper having a coating structure in which styrene-butadiene latex distribution of a paper coating layer is controlled in order to reduce fold cracking of the coated paper and a method for manufacturing the same. The coated paper in which different types of latexes are separately applied to two coating layers exhibits considerably improved stiffness and reduced fold crack, as compared to the existing coated paper.
Abstract:
A virtual channel table for broadcasting protocol and a method for broadcasting by using the virtual channel table includes identification information identifying and permitting discrimination of active and inactive channels contained in the virtual channel table. At a receiver, the virtual channel table transmitted from the transmitting side is parsed, thereby determining whether the current received channel is an active or inactive channel.
Abstract:
A digital broadcast receiving apparatus for providing an integrated service of a 2D image and a 3D image. The apparatus comprising a demultiplexing unit configured to demultiplex a received digital broadcast signal; a PSIP or PSI/SI processor configured to extract at least any one of 3D service information related to a 2D image channel or service and 2D service information related to a 3D image channel or service from the demultiplexed digital broadcast signal; a decoder configured to decode an extension view video stream and a base view video stream from the demultiplexed digital broadcast signal; and an output formatting unit configured to format the extension view video stream and the base view video stream based on at least any one of the 3D service information and the 2D service information.

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 declarative contents and a first PDI (Profiles, Demographics, Interests) table including a first PDI question having a first question id for identifying the first PDI question and receive a second PDI table including a second PDI question having a second question id for identifying the second PDI question, an obtaining module configured to obtain an answer to the first PDI question, a storing module configured to store the obtained answer to the first PDI table, a fetching module configured to fetch the stored answer to the second PDI question by using the first question id and the second question id, wherein the first question id is equal to the second question id, wherein the storing module further stores the fetched answer to the second PDI table and a downloading module configured to download contents using the fetched answer, wherein the declarative contents fetches the stored answer by using an API (Application Programming Interface).
