I. INTRODUCTION
DVRP is a digital recording system that is based on the Alacron FastFrame1300 family of
frame grabbers. The application works under Windows 2000/NT/XP operating systems. The
DVRP system enables recording of video from a variety of digital and analog sources.
DVRP enables recording of high frame rate images to system disk files. The Frame rate to
the disk files depends on the hardware configuration.

2
II. INSTALLATION
Follow these instructions to install the DVRP software:
Insert the DVRP installation CD-ROM into your CD-ROM drive. Access your CD-ROM drive, go
to ”\Setup” directory and double click “DVRP-win2k-obj-x.y.z.exe” to run the DVRP installation.
Follow the “InstallShield Wizard” on screen instructions. After the installation is complete, reboot
the PC System to complete the software installation and the environment setup.

III. USER’S GUIDE
A. Operating Modes
The DVRP system operates as a dual-channel high-speed digital recording and playback
system. It can record continuous stream of images (frames) from two separate synchronized
digital cameras, each providing 40-60 Mpixels/sec. The DVRP system can be configured to
accept Camera Link, parallel LVDS, analog and all other input and output formats supported
by Alacron’s FastFrame FF1300 board.
The DVRP system controls are very simple and intuitive, similar in function to controls of a
typical Digital Camcorder, DVD player or VCR.
B. Main Screen
After starting the DVRP application user will see large main screen that can be positioned
anywhere in the system window. This screen combines two horizontal image display
windows, recording and playback indicators, and essential application controls.
Figure 1: DVRP main screen
During DVRP operations the main canvas will be horizontally split into 1024x512 pixels
windows to display each of the video channels in a separate window.
C. Video Mode Selection

4
The first step to start using the DVRP software is to select the camera type by opening the
“Select Mode” Dialog (Figure 2). This dialog enables you to select camera type to be used
for digital recording, configure system for visual playback of pre-stored video recordings, or
initiate video-out mode sending pre-recorded image stream over Camera Link or other type
of video interconnect. The “Demo Record” mode is available for self-diagnostic purposes. It
generates image stream using TriMedia processor on the FastFrame boards and exercises
DVRP system recording capabilities.
After selecting operating mode, the system loads appropriate software to frame grabber
boards and allocates buffers in the host system memory. Completion of the initialization
phase is signaled by highlighting / enabling the “Select Files” button, which was grayed-out
and not selectable before.
Figure 2: Select Mode dialog box
All cameras which will be used with the DVRP system must have corresponding camera
description file camera_name.cap stored in the %DVRP%\Capture folder. See appendix for
more details regarding relevant entries in the capture file.
D. Selecting Files for Record or Replay
This dialog enables you to select and/or create Folder on the RAID storage system for each
of the recording or playback channels. In addition, this dialog box provides optional Timer
selection to control operation during unattended recording.

E. Recording and Playback Controls
1. Record Mode
a) RECORD button
Pressing the Record button starts image capture operation. Video frames captured from
the camera are stored first in the system memory in a circular buffer. An independent
execution thread stores video frames from the buffer on the RAID disks. During DVRP
operations, the image area at the main application window is continuously updated with
the latest video image from the camera at a refresh rate that depends on camera
characteristics and system configuration. The refresh rate might be lower then the
camera frame rate to prevent disturbance to system performance.
The capture operation continues until the user presses the Stop/Pause button or until
expiration of the predefined time period - if timer check-out box was selected in the
“Select Files” dialog
b) PAUSE button
Pressing the Pause button pauses the capturing operation until Record/stop button is
pressed.
c) STOP button
Once a recording command is initiated, the Stop button stops the acquisition process of
the images and storing of images to the buffer.
2. Playback / Video Out Mode
a) PLAY / PLAY-REVERSE button /

6
Pressing the Play button starts image playback operation. An independent execution
thread fetches frames from the disk and refills the buffer. During DVRP operations, the
image area at the main application window is continuously updated with the latest video
image. In playback mode, the video frame rate is user defined using rate controls on the
main windows. In Video Out mode, the video output frame rate is according to recorded
rate from the camera in Video Out mode. Changing the frame rate parameter in the
output configuration file (output. cap), allows playing video out in reduced rate.
The playback operation continues until the user presses the Stop/Pause button or until
the end of file/s.
The play operation is enabled after choosing files, going to first/last frame or stepping
one frame.
b) PAUSE button .
Pressing the Pause button pause the video playing and enables the step by step
buttons.
c) STOP button
Pressing the Stop button stops the video playing/output and enables the First/Last
buttons.
d) First button
Pressing the First button jumps to the first frame in video stream. The system is ready to
play in either forward or backward directions.
e) Last button
Pressing the Last button move to the last frame and the system is ready to play in either
forward or backwards.
f) Next Frame button
Move to the next frame. The system is ready to play in either forward or backwards or
continuing stepping forward or backwards.
g) Previous Frame button
Move to the previous frame. The system is ready to play in either forward or backwards
or continuing stepping forward or backwards.
F. Frame Converter
DVRP Frame converter converts frames from internal DVRP unique file format into separate
file per frame in TIFF file format or into single multi page TIFF file.
To operate the converter, type the source file name in the Source Edit Box and press the
Load button. If the Source Edit Box left empty, a standard Windows Open File Dialog will
opened allow the user to select the desired file. After loading the file, several properties are
shown, including number of frames stored in the file and time stamps of beginning and end of
record. The converter allows converting partial selection of frames. The default is from the
first frame to the last available frame. In case of recording from more then one camera, the
conversion process should be performed per camera.
