<P>PROBLEM TO BE SOLVED: To provide a video recording apparatus capable of recording for long hours with high reliability. <P>SOLUTION: A video recording apparatus comprises: a writing control section; and a read-out control section. The writing control section creates video data a-f, each of which is a data unit capable of being reconstructed alone into a video, based on image data A1 imaged by a monitoring device, and aligning the video data in time series so as to make a write video stream B1. The writing control section also records each of the video data a-f on a recording medium 232 and an HDD 231 alternately. The read-out control section reads out the recorded video data a-f so as to reproduce the video data into a read-out video stream C1a. Even if either of the recording medium 232 and the HDD 231 is broken and the video data cannot be read out from the recording device, the read-out control section can reproduce video with a reduced frame rate by reading out the remaining readable recorded video data without leaving those of any data because each of the remaining readable recorded video data is a unit capable of being reconstructed alone into a video. <P>COPYRIGHT: (C)2012,JPO&INPIT |
