CAPABILITIES
A DGy 201 recording can be replayed directly from a DGy 201 from the
internal drive or remotely mounted disk (option). The file created by DGy
201 can also be viewed from a suitably configured PC at a reduced
frame rate. The DGy 201’s playback capabilities are listed and illustrated
in the following section. For details about playback from a PC, refer to
the following section “Software Replay Application”.
LOCAL PLAYBACK
For local viewing, the DGy 201 is typically configured to replay from the
installed drive(s) to the analog RGB or DVI outputs, as shown in the
figure below.

SOFTWARE REPLAY APPLICATION
A Windows® software application supplied by RGB Spectrum can be
used with PCs to replay DGy 201 recordings directly on the PC. The
quality level will be the same, but at reduced frame rates. This
application works with the standard Windows® Media Player (version 9
and above) to provide basic transport functionality including play, pause
and stop.
This application can be used to replay recordings in the following ways:
•Recordings copied from a DGy 201 to the PC local drive using
the popular TCP/IP file transfer protocol (FTP).
•Recordings played out from a DGy 201 removable drive
inserted in an appropriately configured PC equipped with a
compatible removable disk drive bay. Note that DGy 201 uses
the ext2 file system found with the Linux operating system. PCs
running the Windows ® operating will require additional software
in order to mount the drive under the Windows® operating
system. Commercial software is available for this purpose.
Playback quality is high, but note that the playback frame rate is limited
by the performance of the selected PC. As an example, a PC equipped
with a Pentium IV 3GHz CPU with 512 MB of memory will typically play
a 1280 x 1024 recording at about 5-6 frames per second.
