Embodiment Construction

[0010] figure 1 It is a flow chart of a preferred embodiment of the digital audio-visual data storage method of the present invention. This storage method is used in a digital video device, such as a digital camera, a digital video recorder, and the like. The digital video recording device includes a storage memory and a system memory. The former is used to store video and audio data captured during video recording, which will not disappear because the video recording device is turned off; the latter is used to temporarily store data because of its faster access speed Fast and convenient for various related data processing. Such as figure 1 As shown, this process includes the following steps:

[0011] Step 11: loading the file configuration table of the storage memory into the system memory;

[0012] Step 12: According to the file configuration table, find out at least one available storage block in the storage memory for use by a digital video file;

[0013] Step 13: sto...

Abstract

The method includes following steps: in process of making digital video recording, a corresponding index between file configuration table renewed along with the recording progress and the video file are previously saved in the storage device in video device; if the video recorder is suddenly interrupted before closing the recorded video file, the pre-stored corresponding index can be used to pick up the recorded video material before interruption, and to restore the recorded video file.

Description

technical field [0001] The invention relates to digital video recording, in particular to a digital audio-visual data storage method which can avoid file damage caused by sudden interruption. Background technique [0002] Commonly used digital video recording devices, such as digital cameras, digital video recorders, etc., during recording, once a sudden interruption occurs (such as a video device crash or a sudden power failure), the previously captured digital audio-visual data will be lost. May be lost. Digital video recording devices generally have a store memory and a system memory. The storage memory is used to store the audio-visual data captured during video recording, which will not disappear when the video device is turned off; the system memory is used to temporarily store data, because of its fast access speed, it can facilitate various related operations Data processing, but once the power is cut off, the stored data will be lost. For example, in a digital ca...
