Disclosed are a customized scent diffusing device and a customized scent diffusing method for effectively transferring sensibility which can be felt from contents to a user by diffusing a most appropriate scent by synchronization with digital contents. According to various exemplary embodiments of the present invention, although odor effect information in 4D contents does not correspond to a spice cartridge configuration in a scent diffusing device, an appropriate odor can be provided through combining or mixing spice cartridges in the scent diffusing device.

Controller for scent diffusing device and a server for supporting the controller

Disclosed are a method for providing a time machine service based on an SNS (social network service), including: extracting keywords based on SNS information input by SNS users and collecting rich contents relating to the SNS information based on the keywords; dividing points of past, present, and future, based on a predetermined present time period and classifying the rich contents into any one of past information, present information, and future information, based on the division result; and providing the classified rich contents to the SNS users.

Method and apparatus for providing time machine service based on social network service

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.

Method and apparatus for encoding and decoding multi-view video using image stitching

Disclosed is a video displaying apparatus including: a projector screen; at least one camera disposed at a predetermined position of the projector screen to acquire a user's video; a communication unit receiving the other party's video from the other video terminal and transmitting the user's video acquired through at least one camera to the other video terminal; and a projector outputting the other party's video so that the other party's video received from the communication unit is displayed on the projector screen.

Video displaying apparatus and controlling method thereof

The present invention relates to a system and a method for tracking a location of a mobile terminal, and more particularly, to a system and a method for tracking a location of a mobile terminal using a TV connected to the Internet. The system for tracking a location of a mobile terminal according to an exemplary embodiment of the present invention includes: a TV connected to the Internet; and at least one mobile terminal acquiring its own location information, wherein the mobile terminal transmits its own location information to the TV in a peer-to-peer communication scheme, and the TV receives the location information to display the received location information on a screen.
