1. Can
I get tendency reports and percentages from my play-by-play
game data in EXCEL?
Yes. With TigerViz, coaches can list of all occurrences for a particular situation,
and identify the percentage of occurrence for each situation. For example,
list all offensive plays from the right hash mark inside the 20 yard line,
or list all occurrences when they ran Pro I Power 8 Toss from their left hash
mark. This feature is accessed through the PRINT SELECTION button on the TigerViz
Video Playback application.
2. What additional
computer storage does the TigerViz system require?
When using DVD’s, TigerViz requires no additional computer storage for
video. Your video footage is stored on the DVD! The TigerViz software stores/retrieves
DVD-Video frame-codes to/from your EXCEL spreadsheet.
TigerViz also allows you to copy your DVD-Video
to your computer’s hard disk drive (HDD), and use those
video files for playback. In this case, storage requirements
are approximately 1.6GB per 45 minutes. So if you have 2
camera angles, 45 minutes each, per game, then the HDD storage
requirement will be 3.2GB per game.

3. Do I need a high-end
video card or additional memory in my PC in order to run
the TigerViz software?
If you are using the Pioneer DVD-V7400 for your video playback, then no special
video card or additional memory is needed. All you need is a PC with Microsoft
Windows 98/NT/2000/XP running either Microsoft EXCEL 97/2000/XP.
If you are using your PC’s DVD-ROM drive
for DVD-Video playback, or you are playing video from your
computer’s disk drive, then the Windows XP operating
system is required, and it is recommended that a graphics
card with at least 16MB of Video RAM be installed in your
PC, and we recommend using an ATI RADEON graphics adapter with 128Mbytes of Video RAM.
4. Which DVD Recorder
should I use?
Use any Panasonic DVD Recorder. Other DVD Recorders may not work correctly using TigerViz frame-based playback mode.

5. How do I get
my video footage onto the DVD, and how much time does it
take?
Play your video footage into the DVD recorder from either your video camera,
a VHS player, or S-VHS (s-video) player. Then finalize the DVD as a DVD-Video.
The DVD-Video is then ready for copying to your computer’s hard disk,
or can be used in either the Pioneer DVD-V7400 or your PC’s DVD player.
This recording process takes the duration of the footage being played, plus
5-10 minutes for DVD-Video finalizing. A typical high school football game’s
videotape is 30-40 minutes for each angle. A typical college football game’s
videotape is 60-80 minutes for each angle. The duration of the raw camera footage
depends on the camera personnel.
6. How much video
footage can I store on a DVD-R?
DVD-R’s 120 minutes (SP mode), and 60 minutes (XP mode). DVD recorder
SP mode produces video that is good quality for athletic viewing. The primary
distinction, as always, is the quality of the original video source.

7. Do I need a special
camera in order to use the TigerViz system?
No special camera is required. The equipment providing video to the DVD recorder
must have one of the following industry standard output formats:
- composite (standard VHS)
- s-video (S-VHS)
- component
- DV (Fire Wire)
8. Can I connect
the Pioneer DVD-Video player to my video projector?
Yes. The versatile Pioneer DVD-V7400 DVD-Video player outputs include industry
standard composite video, s-video, and component video. Connect the DVD-V7400
to a video projector, to a video monitor, or to your PC video capture card.
Many of today’s PC also have dual-head
video cards that allow the DVD player window to be output
to a separate screen in NTSC or S-Video format. Therefore,
from your PC you can play video on your video projector or
television.

9. Can I connect
my PC’s video output to my video projector?
Yes. It is preferable to use a PC with dual video output capability so the
video is displayed on its own screen. In this case, the second video output
would be connected to the display device.
10. What
comprises a complete TigerViz system?
A complete TigerViz Digital Video Playback & Analysis System consists of
a Video Timing Capture / Nonlinear Video Playback Station, and a DVD recorder.
The Video Timing Capture / Nonlinear Video Playback Station is comprised of
one of the following configurations:
TigerViz with Pioneer DVD-V7400:
- The DVD-V7400 connected to: Your PC’s
COM1 or COM2 serial port A video display device, such as
a television, a video monitor, or a video capture card
in your PC
- Your PC running Microsoft EXCEL,
and the TigerViz Video Timing Capture and Nonlinear Video
Playback & Analysis software.
- Possibly a VCR for recording the video output
to tape (e.g., Intercut, or specific game situations).
The VCR would be connected in daisy-chain fashion with
the video display device.
TigerViz with Internal DVD–Video
Player:
- Your PC running Windows XP with DVD-Video
playback, Microsoft EXCEL 2000/XP and the
TigerViz Video Timing Capture and Nonlinear Video Playback & Analysis
software with DVD-ROM drive support.
- The DVD recorder can be located wherever
there is easy access to the original video footage source.

11. How does the
TigerViz software give me nonlinear playback of the content
on my DVD-Video?
Each DVD-Video has an associated EXCEL spreadsheet that is generated by the
video timing capture process. During video timing capture, TigerViz captures
start/stop frame numbers from your DVD-Video for each segment selected by the
operator, and then stores that information in the EXCEL spreadsheet.
The nonlinear video playback portion of TigerViz uses the start/stop frame
information from your EXCEL spreadsheet to select video playback from
the DVD-Video that is in either the DVD-V7400 or your PC’s DVD-ROM drive.
12. What terminology
does TigerViz use to select plays for playback?
TigerViz uses the terminology you use when you generate your play-by-play EXCEL worksheet.
The column headers in the associated worksheet are automatically loaded into
TigerViz. Therefore, search and selection criteria is based on terminology
you define, such as formation, motion, coverage, defensive front, play call,
etc.

13. What is the
difference between Video Timing Capture and NonLinear Video
Playback?
Video Timing Capture is used to store frame markers and game situation information
for each play in the EXCEL worksheet. NonLinear Video Playback
is used to play back the DVD-Video footage, in nonlinear fashion, using information
entered with Video Timing Capture. For example, select all Offense 3rd and
long from the right hash mark, where the play call was Pro I Power 6 Pass.
TigerViz NonLinear Video Playback uses the frame markers in the selected EXCEL rows
to control the video playback.
Checkerboard (intercut) playback, for example,
can be obtained using NonLinear Video Playback if frame markers
are stored for both Wide & Tight angles for each play.
Figure 1 below shows the NonLinear Video Playback graphical
user interface with an associated EXCEL worksheet.

14. Can I
use my play-by-play game data to select plays for video
playback?
Yes, and that is what the TigerViz system is all about. Store your play-by-play
game data (such as play #, down, distance, yard line, formation, etc) in an
EXCEL spreadsheet, and capture the video start/stop frame information
for each play using the timing capture portion of TigerViz. Then, you have
your play-by-play game analysis, and access to each play’s video clips,
all in the same system.
15. Can I record
VHS or S-VHS tapes from TigerViz system?
Yes. The DVD-V7400 DVD Player’s video outputs are compatible with VHS
and S-VHS VCRs. You can also use your PC’s second video output is if
available.
16. Can I store
and retrieve multiple video angles for each play?
Yes. The TigerViz system supports unlimited video angles. Video playback can
checkerboard (intercut) angles, or can play back a selected angle.
Return to Top
17. Is TigerViz
specific to football, or can it be used for other sports
as well?
The TigerViz system can be used for other sports as well. TigerViz is also
being used for basketball.
18. Can I run TigerViz
on my Macintosh?
No, a PC with Microsoft Windows 98/NT/2000/XP, running Microsoft
EXCEL 97/2000/XP is required.
19. How can I use
TigerViz to select and playback the plays that meet a certain
criteria, such as “all 3rd and long pass plays?”
You can directly sort and select all rows that meet your specified criteria
using EXCEL directly, or you can use the Selection Criteria
portion of TigerViz’s nonlinear video playback to specify selection criteria.
TigerViz’ graphical user interface contains a Selection Criteria section
with which you can specify EXCEL selection criteria. For example,
if you have columns for Down, Distance, and RunPass in your EXCEL spreadsheet,
you can select for playback all plays where team A is on offense with 3rd down,
distance greater than 5 yards, and they threw a pass.

20. How should
I duplicate my DVD’s?
Duplicate DVD’s can be generated in one of three ways:
- Use a stand-alone DVD recorder such as
the Panasonic DMR-T3040 with which you can store the video
on the hard drive. Then you simply burn DVD’s from
the recorder’s hard drive.
- Use a DVD duplicator such as the DiscMakers
EliteMicro™ DVD Duplicator (purchased separately)
for DVD duplication.
- Buy a DVD reader/writer for your PC. Today’s
DVD reader/writer drives come with recording software.
With this setup, the quickest way to duplicate a general
use DVD-Video is to copy the Video_TS folder from the DVD
to your PC’s hard disk. The copy that Video_TS folder
as a data copy to a blank DVD. This DVD burn process takes
about 10-15 minutes and produces a bit-for-bit replica
of the original DVD-Video. (The Video_TS is the title segment
folder, and folder contains all information on DVD-Video.
The Video_TS folder is accessed using the Windows Explore
command. (right-click | Explore)

21. How can TigerViz
be used to implement a video exchange policy between teams?
Many intercollegiate athletic conferences benefit from standardized exchange
of game video between teams. One exchange format for football is ODK Wide/Tight
Intercut. ODK Wide/Tight Intercut is Offense Wide and Tight, Defense Wide and
Tight, and Kicking Wide and Tight.
Video exchange requirements such as ODK Wide/Tight
Intercut are easily met using TigerViz – just send
the opponent a DVD-Video and an EXCEL spreadsheet.
TigerViz easily meets this sort of video exchange requirement
because general use DVD’s are easily duplicated, and
the associated EXCEL spreadsheet is easily
exchanged using e-mail. The exchange spreadsheet contains
the game sequence with only the ODK and video frame codes
tagged for each play. An example of such a spreadsheet is
shown in Figure 2 below.
Figure 2. TigerViz spreadsheet containing
only the DVD frame codes (hidden as comments in the WIDE/TIGHT
cells) and O/D/K tags.
Once the DVD and spreadsheet are distributed,
each coach can enter their own information on the received
spreadsheet, according to their needs. The result is each
coach having identical DVD’s and a tailored EXCEL spreadsheet
that meets that coach’s video playback needs.
For example, the defensive line coach adds
detail on defensive line performance in his spreadsheet,
while the defensive backs coach provides detail on coverage
calls in his spreadsheet. Both spreadsheets are used to access
video from identical DVD’s.
A key advantage of this kind of exchange is
the time saved by video staffs because exchanged video is
already tagged. Effort is not duplicated between teams.
In summary, video exchange using DVD-Video
and Microsoft EXCEL with TigerViz provides coaches with
first-generation video quality, and saves coaches time by
sharing time tags and ODK tags for each DVD-Video.
