摘要： A system includes a storage device to store a plurality of media segment files captured at a first location, and a management server storing first metadata sets respectively associated with at least one characteristic of the plurality of media segment files. The management server may be configured to: receive a message from a user terminal requesting a media segment file based upon the at least one characteristic; transmit a second metadata set corresponding to the at least one characteristic to the user terminal in response to the request message; and transmit, in response to a request for media segment files associated with the second metadata set, the requested media segment files to the user terminal.

摘要： Embodiments of the present disclosure relate to an apparatus and method for adjusting an attitude of a target object. An attitude adjusting apparatus includes: a driving device that includes a motor that generates a driving force; and a controller that adjusts an attitude of a target object by referring to a rotation angle of the motor. The driving device includes: a sensing module that generates a magnetic field and senses a change of the magnetic field; and a target that rotates by the driving force of the motor, the target including one blade that changes the magnetic field generated by the sensing module, and the controller determines the rotation angle of the motor by referring to the change of the at least one magnetic field sensed after a preset waiting time has elapsed from a point in time at which rotation of the motor is terminated.
