FIELD: physics, video.SUBSTANCE: invention discloses a device for recording video and audio and a method of editing video and audio. The recording device has a control module. The control module performs break-down editing and stops break-down editing. During break-down editing, source data are deleted based on given recording modules, and editing data formed based on variable-length recording modules are recorded on top of the source data based on the given recording modules. The editing data are input from the source data, read from a recording medium based on the given recording modules, synchronously at a rate at which first video and/or first audio data are reproduced. When deleting part of the source data, the control module records on the recording medium control information which indicates that the physical region in which the deleted part of source data was recorded is defined as a backup region. When editing data are input in response to an instruction to begin editing, editing data are recorded preferably on top of the physical region defined as the backup region.EFFECT: reduced fragmentation of information on a recording medium as a result of editing.4 cl, 11 dwg |
