Havis-Shields PT-VIDEO-MDVR manual Compact Flash File Structure

COMPACT FLASH FILE STRUCTURE

In the root directory of the Compact Flash card, the DVR will create a new subdirectory for each day of recording. The subdirectory is named as follows:

Mmm.dd.yyyy

Mmm = 3 letter month abbreviation, e.g. Jan, Feb, Mar, ...

Dec

dd = day (01 - 31)

yyyy = 4 digit year, e.g. 2006

Each subdirectory will contain one or more AVI files named as follows:

ssssssssssssss_Mmm.dd.yyyy_hh.mm.ss.avi

sss..= User defined system name. This name can be from 0 to 14 characters in length. This field is free-form for the end user to define car number, officer name, whatever within the 14 character limitation. The user is free to put spaces within this name, but these are replaced with underscores ('_') in the filename.

Mmm.dd.yyyy = same as directory name

hh.mm.ss = 24 hour time in hours, minutes, and seconds

.avi = AVI file extension

NOTES:

. If the system name is 14 characters in length, then there is no trailing underscore after the system name.

. File names can contain a 'suffix' which indicates that the file is a continuation of a recording (every 10 minutes, the DVR starts a new file). Also, an event can be marked with a suffix. The suffixes are:

'+' : this is a continuation file

'#' : this file contains an 'event' of interest

The suffix is placed just prior to the file extension, e.g:

Jan.01.2006_01.00.00.avi	/* First file	*/
Jan.01.2006_01.10.00+.avi	/* Continuation file */
Jan.01.2006_01.12.15*.avi	/* Event file	*/
