Abstract: An engine room undercover assembly for a vehicle includes an aerofin mounted on a lower side surface of the undercover to guide airflow under an undercover. In the engine room undercover assembly, the aerofin is configured to maintain a state of being inserted and folded into the undercover when the vehicle is stopped or travels at a speed of less than or equal to a predetermined speed. When the vehicle travels at the speed greater than the predetermined speed, the aerofin protruded to the outside of the undercover to guide the airflow under the undercover.

Abstract: Provided is a 360-degree image encoding apparatus and method, and a recording medium for performing the same function. The 360-degree image encoding apparatus divides an input image to be encoded into a plurality of regions in a vertical direction and encodes the divided regions while changing resolutions thereof so that all regions have the same resolution to maintain pixel continuity among the regions when a predictive image is generated and the regions have resolutions changed according to the degree of distortion of the regions when a residue image is encoded.

Abstract: A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of media content are provided. The media content may include a sequence of one or more periods. The metadata may include a start time attribute and/or a duration attribute of each of the periods. The metadata may determine a start time of each of the periods, and a start time of each of segments included in each of the periods. A terminal may access segments included in each of the periods, may decode and render data of media content included in the segments, and may play back the media content.
