Abstract: Provided is a method of predicting an unsafe approach during an approach phase of a flight. The method includes: receiving static flight metadata related to the flight from an external server; extracting a flight data recorder (FDR) data set of the aircraft for a safe approach to a destination of the aircraft from history data of flights of the aircraft to the destination stored in advance; selecting parameters related to unsafe approaches based on the static flight metadata and the FDR data set; extracting time series data for the FDR data set taking into account the parameters related to the unsafe approaches; selecting an event variable to be used for an unsafe approach determination based on the time series data; generating final prediction data by weighting the time series data for the event variable; and determining whether an unsafe approach is predicted or not based on the final prediction data.

Abstract: Disclosed are a method and an apparatus for generating metadata of immersive media and disclosed also are an apparatus and a method for transmitting metadata related information. The apparatus includes: at least one of a camera module photographing or capturing the image; a gyro module sensing horizontality; a global positioning sensor (GPS) module calculating a position by receiving a satellite signal; and an audio module recording audio; and a network module receiving sensor effect information from a sensor aggregator through a wireless communication network; and an application generating metadata by performing timer-synchronization of an image photographed based on the camera module, a sensor effect collected by using the gyro module or the GPS module, or audio collected based on the audio module.

Abstract: Disclosed is an apparatus and a method for processing additional media information, including an acquisition unit to acquire, from a database, when media data is input through an interface, a pattern corresponding to the input media data and a processor to determine a sensory effect corresponding to the acquired pattern and generate a first annotation of the determined sensory effect.

Abstract: A method and apparatus for generating immersive media and a mobile terminal using the method and apparatus is disclosed. An apparatus for generating immersive media comprises an image generation unit generating image data based on image signals, a sensory effect data generation unit generating sensory effect data by obtaining information related to a sensory effect for providing a sensory effect in conjunction with the image data, and an immersive media generation unit generating immersive media based on the sensory effect data.

Abstract: A frequency error estimator and an operating method of the frequency error estimator are provided. In the frequency error estimator and the operating method of the frequency error estimator, a frequency error between a transmitter and a receiver of a mobile communication system using a reference code is calculated, thereby improving the precision of estimation while reflecting variations in frequency over time.
