Abstract: The present disclosure provides a method and a device for synchronization between a video frame and an audio frame on the basis of high-speed transmission of a VoD content. A content delivery server includes a transceiver and a processors. The transceiver receives, from a content requesting terminal, a search request for a specific playback time within a VOD content. In response to the search request, the processor deletes one or more audio frames existing between a video frame that corresponds to the requested playback time and an audio frame that corresponds to the requested playback time; and generates content data reconstructed to include all or part of frames existing in a period of time from the video frame that corresponds to the requested playback time to the audio frame that corresponds to the requested playback time. The transceiver transmits the reconstructed content data to the content-requesting terminal.
