Abstract: There is provided a cooperative driving control method based on a vehicle security status. The cooperative driving method according to an embodiment includes: identifying a security status of a cooperative driving target vehicle; determining a cooperative driving strategy according to the identified security status; and controlling driving according to the determined cooperative driving strategy. Accordingly, cooperative driving may be performed or excluded based on a security status of a target vehicle, so that an accident may be prevented from being caused by cooperative driving with a problematic vehicle, and safety of a driver and an occupant may be guaranteed.

Abstract: A calibration method of an optical coherence tomography (OCT) device and a camera using the same target includes irradiating a shape measurement light to a calibration target, obtaining a surface shape image thereof by detecting light reflected by a surface of the calibration target using a shape measurement camera, and calibrating the surface shape image according to an actual shape of the calibration target; obtaining surface and internal three-dimensional images of the calibration target by scanning with a layer measurement light using the OCT measurement unit, extracting a surface shape image of the calibration target from the three-dimensional images, and calibrating the surface shape image according to the actual surface shape of the calibration target; and matching a calibration image obtained by the shape measurement camera and a surface calibration image obtained by the OCT measurement unit to be displayed at the same spatial coordinates.

Abstract: Provided is an apparatus and method for processing voice data. The voice data processing apparatus according to an embodiment of the present disclosure includes: a data receiver configured to receive voice data; a storage configured to store the received voice data in a buffer; a section classifier configured to divide the stored voice data into one or more sections, and to classify each of the one or more sections as a voice section or a silent section; and a voice outputter configured to drop voice data classified as the silent section, or to output the voice data classified as the silent section by accelerating a playback speed.

Abstract: Provided is a method for a packet transmission apparatus to transmit a packet in real time, the method comprises determining, by the packet transmission apparatus, whether a buffer occupancy (an occupancy of a buffer) is a threshold value or more, in response to the buffer occupancy is greater than or equal to the threshold value, extracting, by the packet transmission apparatus, a degree of influence of the packet on quality of experience (QoE) and in response to the degree of influence of the packet on QoE is less than or equal to a predetermined value, dropping, by the packet transmission apparatus, the packet before the packet is transmitted to a network.

Abstract: There is provided a method of switching from multipoint communication to point-to-point communication while a device performs the multipoint communication with a plurality of participant devices. The method comprises: sharing, by the device, peer-to-peer (P2P) connection information of the device and P2P connection information of each of the plurality of participant devices, with the plurality of participant devices; and switching by the device, from the multipoint communication to the point-to-point communication using the P2P connection information of remaining participant devices of the plurality of participant devices in the multipoint communication when a total number of the remaining participant devices of the multipoint communication decreases to two.

Abstract: There is a problem in conventional technologies in that updating multimedia content can be initiated only by a mobile communication terminal side. A mobile communication terminal according to the present invention updates at least one of elements of content stored in a permanent storage area of a memory unit using update information included in an update message received through a wireless communication unit, and plays the updated content. The content can be updated from text information included in the update information, files stored in the mobile communication terminal, or network resources. Accordingly, content providers can update the content stored in the mobile communication terminal by transferring the update information of the content to be updated, for example, using an update message which is a push-type communication means such as a text message.

Abstract: Users desire to add their own produced images to multimedia content, or to update the multimedia content. However, there is a problem in that conventional multimedia content cannot be changed. A mobile communication terminal according to the present invention monitors an occurrence of an event, changes at least one of elements of a played content file to a new element when the event occurs, and plays the content file including the changed element by means of a playback unit. The new element to be changed may be an element received from a storage medium connected on a network, a new file stored in a memory unit, or an image taken by a camera module.
