JVC GY-DV5000U DR-DV5000U DV Video Disk Recorder 44 page instruction manual - Page 20

Normal Record Standard and default record mode. When REC is triggered, DR-DV5000 begins standard recording. A single press of a STOP trigger will put DR-DV5000 into REC PAUSE mode. A second press puts DR-DV5000 into STOP mode. Retro Disk Record Mode RETRO DISK Record Constantly buffers video in a loop to a determined amount of space on the HDD so that when record is triggered, a retro time period can be added to the beginning of any clip. RETRO DISK has the following characteristic. Pressing a REC TRIGGER when in RETRO DISK mode puts DR-DV5000 into a RETRO DISK state (DR-DV5000's tally light will flash as if in PAUSE state). DR-DV5000 is actually recording in this state, but until the RECORD TRIGGER is pressed a second time, the video recorded will record over itself in a continuous loop. RETRO DISK always keeps at least the amount of time that is selected by the end user in a series of one minute clips. For instance, if the user sets the RETRO DISK value to 3 minutes, they will always have 3 minutes (made up of three, one (1) minute clips) of video saved to disk. As the recording goes past the 3 minute point, a fourth clip is created. Once that clip reaches FireStore DR-DV5000 User Guide one minute, the oldest of the previous 3 clips is deleted. Another fourth clip is then created. If a user selects a RETRO session that is 60 minutes or greater, instead of one minute clips, DR-DV5000 creates 9 minute, 13 second clips (2GB clips on disk). The characteristics of RETRO DISK remains the same. The larger file size prevents DRDV5000 reaching its 999 track limitation for very long RETRO records. Due to the larger files sizes, the maximum amount of drive space available is decreased in order to accommodate the last recording in a session. For instance, if a user has 90 minutes of disk space remaining, after the user sets RETRO record to greater than 60 minutes, the available space changes to 88 minutes of available disk space. If the user sets RETRO time to 88 minutes, the recording will be made up of about nine and a half 9 minute, 13 second clips. There must be space available in this situation in order to record the final clip which eventually will right over clip 1. This ensures that at any given time, at least 88 minutes of video exists after a compete RETRO DISK record loop. NOTE: DR-DV5000 must always have at least one minute of disk space (under 60 minutes) or 9 minutes, 13 seconds of disk space (when RETRO DISK value is set to greater than 60 minutes) remaining in addition to the RETRO DISK value that has been set, in order to function correctly. For instance, it is not possible to set a RETRO DISK value of one minute if only one minute of disk space remains. PAGE 19
