Direct-to-disc fault-tolerant method for videos in hard-disk based digital video recorder and device thereof

Abstract

The invention relates to the field of digitalized interrogation, and discloses a direct-to-disc fault-tolerant method for videos in a hard-disk based digital video recorder and a device of the direct-to-disc fault-tolerant method for the videos in the hard-disk based digital video recorder. In a video direct-to-disc process, if a certain optical disc fails in recording due to various reasons and is popped out of a compact disc (CD) driver, a system can restore the videos automatically after a user places a novel disc, videos from a starting time of the self-recording failure disc to a current time are all restored to the novel disc, seamless connection is maintained between the videos and subsequently generated video data, the stability and the reliability of the system are effectively improved, and the problem of video data incompleteness caused by recording errors is solved. An additional supplementary recording method is utilized for achieving data fault-tolerant technique, the completeness of the video data in the direct-to-disc process can be guaranteed, and the seamless connection can be maintained between the video data before an optical disc recording failure and the video data after the optical disc recording failure.

Description

technical field [0001] The invention relates to the field of digital interrogation, in particular to the fault-tolerant technology of interrogation video direct recording. Background technique [0002] Direct recording refers to a recording method that directly fixes the video stream to the disc without transferring data through a third-party storage medium during the recording process. [0003] In the Chinese patent application number 200810121223.8, a method for synchronous direct writing of multiple optical drives is disclosed, which can directly write real-time data to optical discs without generating temporary files, and can simultaneously write to multiple optical drives. However, it does not deal with the failure of disc burning generated during the direct burning process. If an error occurs during the direct recording of the real-time stream, the integrity of the data cannot be effectively maintained. [0004] The interrogation digital hard disk video recorder refe...
