SUMMARY OF THE INVENTION One of the objects of the present invention is to provide a digital image; the r=ff method can avoid the sudden interruption of a factor-recording device and the destruction of a digital video file. The purpose of the invention is to use the following steps: to record the digital video: the digital audio and video recorded by the digital recording device. The data is stored in the system memory == the digital audio and video data stored in the memory is processed, and the processed digital audio and video data is stored in the opened digital video file of the storage memory 1252400; the storage memory is updated - (4) the configuration table And record the job---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- In order to enable the reviewing committee to have a further understanding of the present invention, the embodiment of the present invention will be described in detail below. [Embodiment] Fig. - A flow paste of a preferred embodiment of the digital audio and video data storage method of the present invention. This bribe _ Yu-number scale device, for example = digital camera, digital recording and so on. The number of the tactile devices includes the storage memory and the system memorandum, which are used to store the recording data, which are not captured by the video device. The latter is used for the data, because of the access. Faster speeds make it easy to perform a variety of related data processing. As shown in FIG. 1, the process includes the following steps: Step 11: Load the storage memory configuration table into the system memory; Μ Step 12: Find the storage memory according to the _configuration table At least the available memory block is used for the digital video broadcast; Step 13 n the digital video captured by the video recording device is stored in the system memory; Step 14: According to the digital video file - difficult format, Performing the corresponding data processing of the digital audio and video data stored in the unified memory Γ 1252400 Step 15 · Storing the digital audio and video data processed by the (4) material into the usable memory block; Step 16 · Updating the ray code [setting and One of the digital video slots corresponds to the index; and step 17: the slot configuration table and the corresponding index are updated to the storage memory before the digital recording is turned off. In the second step η, the thief g own table is corresponding to the memory used, and the case system can record the use of each memory block of the memory = heart (for example, use, use, retention or damage, etc.) Wait). The audit file configuration '" can be regarded as a single linked list, that is, if a memory=block is being used by a certain job, in the ride configuration table, the memory block should be an entry. Record the (f) of the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Reflect this fact. The number of η 巾 ’ 彳 彳 彳 影 影 _ _ _ shadow (four) Na audio and video is assembled, stored in the memory. Through step 11 magic 2, 3 to open a digital video, and the available memory & block of the memory is found for the digital video file storage.丨5, the actual _ number of tactile devices rely on the audio and video data stored in the available memory block, you need to first the audio and video data: secondary material, the hidden buffer (ie step 13), and then - Some related r 鳇 鳇 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 14 However, this part of the technology is familiar to those skilled in the art and is not a feature of the present invention, and will not be described here. x / step 16 Weihe step 15 is carried out, when the available memory block is full, 'the subsequent audio and video data will be saved to the next available block, then the corresponding item of the storage configuration table towel needs to be updated (here The system configuration file has been loaded in step u) to reflect this new situation. Another: face, the corresponding index of the digital video file is used to record the video broadcast target = slot length (10) such as 'recording tuple unit', in other words, it will be stored in the memory block (four) with the audio and video data Update. In the embodiment, the pair is indexed at the Wei position. In the current format of various audio and video slots, there are reserved storage fields that users can use themselves, and the corresponding index can be stored therein. For example, if the digital video recorder is a G1 ageing department, the account size is stored in the user data field (the starting code is Wuhu (10) (four). ▲ v step 17 is in the off The digital video file (that is, the end of the video) is updated in the file configuration table and the corresponding index in the second step of the video recording (this time is also stored in the system memory) 'pre-updated to the storage memory In the body, the occurrence of the sudden temperament in the avoidance record causes the update of step 16 to be lost. In the embodiment, the step η can be set to be performed once per pre-expiration time. The shorter the predetermined time, It can retain more captured audio and video data when a sudden interruption occurs. When the digital video device occurs - a sudden interruption, the digital video field ',,,,,,,,,,,,,,,,,, The process is to update the digital video file in advance by storing the memory in 1252400. Here, the sudden interruption is caused by power failure or the machine is generated. The second is to use the digital video and audio storage of the invention. Method for repairing an interrupted digital video file A flow chart of a preferred embodiment. As shown in FIG. 2, the process includes the following steps: Step 21: According to the stored configuration table and corresponding index in the storage memory, the digital video file is captured before the interruption occurs. The digital audio and video data stored in the memory of the memory; and the step 22: repair the Wei number _ shadow slot. Update == Saki, map - the corresponding index of the stored materials, and the Wei video files are stored back to After storing 5, so there is no money _ 敎. And after the digital video device is newly turned on), step 21 is based on the number "mi read the digital video recording rights stored in the memory record (4) === According to the chain _ _ digital file length Wei, can use the corresponding index included in each block is a solid memory channel using several memory blocks (because the last - two solid; large video device can not ^ because 'Because of the sudden interruption, the number is made, that is, the 录影 卜 录影 录影 进行 进行 进行 正常 正常 正常 正常 正常 正常 正常 。 。 。 。 。 。 黎 黎 黎 黎 黎 黎 黎 黎 黎 黎 黎 黎 黎 黎 黎 黎 黎 黎 黎 黎The video recording device has no time to perform the above-mentioned closing, and the error is described. Whether the index is the last - 1252400 block. In step 22, after the last-memory block before the interrupt is traced by the file configuration table and the corresponding index, the file is repaired, that is, the last found is found. A block is re-marked as an end mark. By the flow of the preferred embodiment of the drawings and FIG. 2, the present invention can achieve the effect of preventing the digital video device from causing damage to the digital video slot caused by the burst cap, and further repairing The digital recording becomes a file of positive f for subsequent follow-up. The above-mentioned side test is a detailed explanation of the Japanese invention, not limiting the money of the present invention. Anyone familiar with this woven art can be daring, appropriate The slightest change and adjustment will not lose the essence of the invention, nor the spirit of Lin (4). The specificity of the implementation of this (4) is in line with the requirements of the patent law towel. The Beck Review Committee gave a review of 'and granted a patent as a prayer. [Simple Description of the Drawings] - One of the methods for storing digital audio and video data is better than the flow chart of the embodiment. The flow chart of the preferred embodiment is interrupted by the method of interrupting the transmission of the touch-sensitive audio transfer method.
