Below in conjunction with Fig. 2, for digital hard disc video recorder, the real-time carving method of the CD that the embodiment of the present invention provides is described in detail, specifically, as shown in Figure 2, comprises:

Step 202, digital hard disc video recorder is set up a configuration file, this configuration file for storing the attribute information of the file of imprinting on CD, such as: file name, file size etc.This configuration file can be based upon on non-volatile, the erasable memory device such as hard disk, Flash, SD card, and the attribute information of the file recorded in this configuration file is for the file access pattern under the abnormal conditions such as power-off.

Step 204, the logical tracks of predetermined number is retained as reservation track from the reference position of last section on CD, retain next track of track as data-track, for recording the data treating imprinting file, also can select in this step to be stored into retaining track and the orbit number of data-track and the start address of track in configuration file.

Step 206, when needing a newly-built file on CD in real-time writing process, also namely before this file of imprinting, the file name of this file is stored in configuration file, the start address of this file data of imprinting on CD in this step, also can be selected to be stored in configuration file.

Step 208, real-time imprinting file data.If there are abnormal conditions in the process, equipment is restarted, then perform step 220.

Step 210, judges whether the imprinting terminating current file, if terminate the imprinting of current file, then performs step 212, otherwise, perform step 208 and continue imprinting file data.Certainly, in writing process, if desired limit the size of each imprinting file, then can set a predetermined threshold, just terminate the imprinting of current file when the file size of current imprinting reaches predetermined threshold.

Step 212, when terminating the imprinting of current file, is stored into the file size of this file in configuration file.

Step 214, judges whether to terminate real-time imprinting, if terminate real-time imprinting, then performs step 216, otherwise performs the next file of step 206 imprinting.

Step 216, when terminating real-time imprinting, according to imprinting order and the file size of the start address of data-track, all files of imprinting, calculate the start address of each file engraving data on CD, if select the start address of each for imprinting on CD file data to be stored in configuration file in step 206, do not need in this step to recalculate, can directly obtain from configuration file.

Step 218, according to the start address of each file of imprinting engraving data on CD, file name and file size, structure catalogue listing and listed files, catalogue listing and listed files are stored into data-track end, again according to the root directory information in catalogue listing, structure file system header, and file system header is stored into reservation track, then close and retain track and data-track, and close this section, the configuration file simultaneously set up in delete step 202, once imprinting in real time completes.Also catalogue listing and listed files can be selected in this step to be stored into reservation track, then require that the space retaining track is enough large, file is too much else if, just may there will be the situation retaining orbit space deficiency.

Step 222, if there is configuration file in memory device, the file of imprinting before then needing to recover CD is restarted, the attribute information of imprinting file is then read from configuration file, obtain the imprinting order of all files of imprinting and last file size of all files of imprinting before imprinting file, certainly, the information such as start address of the orbit number retaining track and data-track and start address, each file of imprinting is also likely got.

Step 224, because the file size just in imprinting when equipment is restarted cannot obtain in configuration file, therefore, need to read the start address of data-track from CD and last does not close the last writing address (next in data-track can write address) of closed orbit, then according to the imprinting order of all files of imprinting, last is the file size of all files of imprinting before imprinting file, in data-track start address and data-track, last does not close the last writing address of closed orbit, calculate the file size of the imprinting of last file in data-track.Certainly, if record the start address of the track that fetches data in configuration file, then only need read from CD the last writing address that last does not close closed orbit.After the file size obtaining the imprinting of last file in data-track, according to the file size of the imprinting of the start address of data-track, all files of imprinting order and each file of imprinting, the start address of each file of imprinting engraving data on CD can be calculated.

Step 226, reservation track, data-track and current session in closing CD in current session (section of real-time imprinting file during exception occurs), open a new section simultaneously.

Step 228, according to the start address of each file of imprinting engraving data on CD, file name and file size, structure catalogue listing and listed files, then according to the root directory information in catalogue listing, structure file system header, is stored in new section by file system header, finally closes new section, delete the configuration file in memory device, CD has recovered.Certainly, also can not close the reservation track of current session, data-track and current session in step 226, then by the data-track of the write current session such as catalogue listing, listed files and file system header and track can be retained.
