Abstract

The invention provides a video recording method and a video recording device of digital recording equipment. The method comprises formatting a disk, and then according to a video parameter, computing the size of a file which needs to be established, and after the file is established, writing video data in a video recording period into the established file. After the video data in the last video recording period are written into the file, a novel file is established again, video data in a next video recording period are written into the novel established file, and in video recording process, the video parameter is judged whether to be modified, if yes, according to modified parameter, the size of a novel file which needs to be established is computed and the novel file is established, and video data recorded according to the modified parameter are written into the novel established file. The video recording device records video according to the method. The video recording method and the video recording device of the digital recording equipment can allow the facts that the parameter of the video data can be changed in the video recording process and the size of the file can be changed, so that the flexibility of video recording is achieved.

Description

technical field [0001] The invention relates to the field of digital video recording, in particular to a video recording method of a digital video recording device and a video recording device using the video recording method. Background technique [0002] Existing digital video equipment, such as digital video recorder (Digital Video Recorder, DVR) can be used to record video data in real time, and store the recorded video data in a disk as a storage medium. This technology is widely used in vehicles such as driving recorders. etc. electronic equipment. [0003] Since the digital video equipment records video data in real time and stores the video data in the disk, if the video data is not continuously stored in the disk, file fragments are likely to occur, resulting in low disk utilization. [0004] Therefore, the invention patent application with the publication number CN1750164A discloses an invention titled "A Digital Video Recorder File Management Method to Prevent Fi...
