Abstract:
PURPOSE: A displaying apparatus and a method thereof which display three dimensional images are provided to enable a user to normally display three dimensional image by determining whether to be the existence and nonexistence of the three dimensional images. CONSTITUTION: A display device automatically recognizes the image conversion in a three dimensional image system. A receiver(100) extracts specific information of the display device. A calculating unit(121) calculates a result value by using a reference element and a selection element by selecting a left image or a right image. A determining(120) determines whether the system is normal by using the result value. A correcting unit(130) corrects the left image and the right image according to the determining result.

PURPOSE: A system and a method for transmitting/receiving a non real time 3D broadcast are provided to transmit additional 3D data including a 3D sub image and information for the 3D sub image in non real time. CONSTITUTION: A non real time broadcast server(303) generates a non real time service information table including information required for receiving and restoring a 3D sub image and information for the receiving and restoring the 3D image by a transport stream. A media encoder(301) generates a 2D image by a transport stream of a fixed bit rate based on the bit rate of a 3D sub image transport stream. An ensemble multiplexer(305) multiplexes a 2D image transport stream, a 3D sub image transport stream, and a non real time service information table transport stream in a fixed sub channel.

PURPOSE: An apparatus and a method for supplying information connected with the newspaper media are provided to supply news related information with broadcasting program information and newspaper information on newspaper. CONSTITUTION: A recognizing unit(540) recognizes news link information capable of containing the news information and electronic programming guide. A controller(550) extracts the electronic programming guide from the acknowledged news link information. The controller operates a wireless unit(520) and a modem. A memory stores the electronic programming guide. A display unit offers the extracted electronic programming guide to the form in which the user recognizes.
Abstract:
PURPOSE: A method for providing a three dimensional data service based on DMB(Digital Multimedia Broadcasting) and a method for receiving the same are provided to supply a 3D data service more efficiently and conveniently while maintaining the backward compatability with the DMB that provides an existing 2D data service. CONSTITUTION: The main and supplementary data for data contents which are the target of the 3D data service are generated. Signaling information is generated, and includes channel ID information indicating not only the channel information that is additionally allocated to the main and supplementary data but also the dimension ID information that indicates the dimension of the data contents. A broadcasting stream including the signaling information is created, and a header of the additional data includes the information that defines the relationship with the main data.
Abstract:
An apparatus and a method for rendering a depth based image in mobile broadcasting are provided to apply a discontinuous maintenance filter to a depth image, thereby minimizing distortion of the depth image. A discontinuous maintenance filter(111) smoothes a depth image correspondingly to gradient amplitude of the depth image. An adaptive smoothing filter(115) calculates a gradient degree of the depth image transmitted from the discontinuous maintenance filter. Only when gradient amplitude is larger than a preset value, the adaptive smoothing filter applies a filter feature according to a gradient direction to the depth image. The adaptive smoothing filter transmits the depth image to an encoding module(120). The encoding module transmits a reference image and the depth image.
Abstract:
A system and a method for providing a voice EPG(Electronic Program Guide) service in DMB(Digital Multimedia Broadcasting) and DAB(Digital Audio Broadcasting) systems are provided to make the system completely compatible with an exiting EPG XML(eXtensible Markup Language) and supply a dialog type voice EPG service. A voice EPG service supplying apparatus(700) comprises a composite EPG data generator(701) and a transmitter(702). The composite EPG data generator(701) generates composite EPG data including program information of a voice tag, as data to be used in an EPG service, by using a composite EPG XML where the voice tag is appended to an EPG XML. The voice tag guides program information through voice. The transmitter(702) widely distributes the generated composite EPG data through DMB and DAB broadcasting networks.
Abstract:
A method and an apparatus for providing a synchronized data service with a video service in digital multimedia broadcasting are provided to synchronize the information for representing a performance time of a specific event with the audio/video service. An AV(Audio/Video) signal source(200) generates audio and video contents. A DMB(Digital Multimedia Broadcasting) AV encoder(210) encodes the produced audio and video in order to fit the terrestrial DMB standard. A data server(230) performs various data services. An ensemble multiplexing member(240) multiplexes the generated AV stream and data packet as one ensemble. A DMB transmitting member(250) performs OFDM(Orthogonal Frequency Division Multiplexing) encoding and RF(Radio Frequency) transmission. An NTP(Network Time Protocol) server(220) performs exact temporal synchronization of the devices.
