Pure Digital / CVS Disposable FSP and USP Analysis

Modifying Camera Settings

Cold Storage Default Settings - FSP and USP
Pure Digital's Camcorder for CVS

FSP.BIN and USP.BIN
Pure Digital's software is controlled by two files. These files control the maximum recording time, recording resolution, and the lock/unlock code.

File USP.BIN is the file that is normally used, and is updated when the camera is used (either when a video is recorded or power turned off; I'm not sure).
File FSP.BIN is a backup version used in case USP.BIN has become corrupted.

Only a limited number of resolutions and frame rate combinations are allowed. The sensor size is 640x480, so higher resolutions are not needed. The default is 320x240x30 fps.

Horizontal Resolution	Vertical Resolution	Frame Rate
256	192	24 or 30
320	240	24 or 30
384	288	24 or 30
448	336	24 or 30
512	384	24 or 30
576	432	24 or 30
640	480	24 or 30

Corscaria discovered the initial resolution settings in this file - her announcement here.
GWRedDragon (aka Rick Mansfield) has released a program called USP Patch to modify a USP file. Discussion about this can be found here.
