  • Publication number: 20080095096
    Abstract: Provided is a geographic information transceiving system and method using a digital broadcasting network. The system and method segments new geographic and map data of a region, on which a geographic information service is provided, makes data segment files of different sizes, and multiplexes and transmits the files.

  • Publication number: 20080089405
    Abstract: Provided is a method and apparatus for encoding and decoding multi-view video data. The encoding method includes: decomposing each view image of the multi-view video into an overlapped region and a non-overlapped region, the overlapped region being overlapped with other view image and the non-overlapped region not being overlapped with other view image; generating a stitched image by combining the non-overlapped region of each view image and a middle view image; encoding the stitched image using a first encoding algorithm; and encoding the overlapped region of each view image, using a second encoding algorithm. Further, the decomposing step includes the steps of estimating disparity information for each view image, based on a predetermined view image; and decomposing each view image into said overlapped region and said non-overlapped region using the estimated disparity information.

  • Publication number: 20070296721
    Abstract: Provided are a contents generating apparatus that can support functions of moving object substitution, depth-based object insertion, background image substitution, and view offering upon a user request and provide realistic image by applying lighting information applied to a real image to computer graphics object when a real image is composited with computer graphics object, and a contents generating method thereof. The apparatus includes: a preprocessing block, a camera calibration block, a scene model generating block, an object extracting/tracing block, a real image/computer graphics object compositing block, an image generating block, and the user interface block. The present invention can provide diverse production methods such as testing for the optimal camera viewpoint and scenic structure before contents are actually authored and compositing two different scenes taken in different places into one scene based on a concept of a three-dimensional virtual studio in the respect of a contents producer.

  • Publication number: 20070126927
    Abstract: Provided is a five sensory data synchronizing and transmitting apparatus and method, and an actual-feeling multimedia data providing system and method using the same. The five sensory data synchronizing and transmitting apparatus and method forms packets by describing vibration, an odor and a taste expressed in video/audio based on touch, odor and taste data descriptors and synchronizes the touch/odor/taste packets with video/audio packets on a frame basis; and then, the actual-feeling multimedia data providing system and method demultiplexes the received packets transmitted from the five sensory data synchronizing and transmitting apparatus into video data, audio data, touch data, odor data and taste data and transmits them to corresponding devices to thereby provide a user with an actual-feeling multimedia service.

  • Publication number: 20070115276
    Abstract: The present invention relates to three-dimensional video processing apparatus and method using MPEG-4 object descriptor information and structures. The three-dimensional video processing apparatus and method that can support a three-dimensional video service smoothly to thereby provide a sense of reality and a cubic effect in an MPEG-4-based system by suggesting a three-dimensional video object descriptor structure and providing to a client an object descriptor, which includes information on kind of three-dimensional video, number of viewpoints, number of media streams and a plurality of display methods; and a method thereof.
