Abstract:
Disclosed are a multi-screen display system and a method of correcting a time synchronization of image signals respectively played by unit display panels. The multi-screen display system includes a multi-screen display apparatus configured to include a plurality of unit display panels and a timing sensing apparatus configured to sense, outside the multi-screen display apparatus, time synchronization information about the unit image frames respectively played by the unit display panels. The timing sensing apparatus calculates a time synchronization error between the unit image frames respectively played by the unit display panels, based on the time synchronization information, and transmits the time synchronization error to the multi-screen display apparatus.
Abstract:
Provided is a route guidance apparatus and method including receiving at least two pieces of route information provided from at least two route providing servers, analyzing the at least two pieces of route information and converting the at least two analyzed pieces of route information to a common data format, classifying the at least two converted pieces of route information into categories of similar routes based on a predetermined similarity level, selecting one of the categories, then selecting, from the selected category, one of the at least two pieces of route information to be a node route for each section node, and interconnecting node routes selected for the respective section nodes, thereby generating an entire route.
Abstract:
Provided are an apparatus and method for transforming augmented reality information of a head-up display (HUD) for a vehicle. The apparatus for transforming augmented reality information of a head-up display for a vehicle includes a first projection transforming formula generation unit configured to extract a conjugate point by performing feature point matching on a first feature point of a forward recognition image of the vehicle input from a forward recognition camera and a second feature point of a first driver-based viewpoint image input from a driver-based viewpoint camera whose installation position is different from that of the forward recognition camera, and generate a first projection transforming formula; a second projection transforming formula generation unit configured to generate a second projection transforming formula using a straight-line intersection of a second driver-based viewpoint image, which is extracted from a second driver-based viewpoint image input from the driver-based viewpoint camera, and HUD coordinates pre-defined on the HUD; and an augmented reality information transformation unit configured to sequentially apply the generated first and second projection transforming formulas to recognition coordinates of a forward object, which is recognized from the first forward recognition image, to calculate primary and secondary transformation coordinates, and render the secondary transformation coordinates on the HUD.
Abstract:
Provided is a packet transmission method of a communication device. The packet transmission method includes randomly determining a first packet transmission time of a first packet which is to be transmitted in an nth beacon interval, generating the first packet, and transmitting the first packet at the first packet transmission time.
Abstract:
Provided is a data transmitting and receiving method in which a display apparatus connectable to a wireless network transmits and receives data to and from a user terminal by using a pointing apparatus. The data transmitting and receiving method includes (a) acquiring position information of a region, pointed by the pointing apparatus, in the display apparatus and (b) transmitting data, corresponding to an object displayed in the region on a screen of the display apparatus, to the user terminal by using the pointing apparatus.
