screen icon indicates when a recording is in progress. VBStar combines digital television
recording, networking and video storage with an MPEG-2 video server in one compact
package. VBStar provides efficient, robust and feature-rich MPEG video storage and
playback capabilities. Through its record and FTP capability, VBStar eliminates the reliance
on broadband networks, including Quality of Service requirements. A VBStar encoder allows
recording and playing audio and high quality 30-frame per second MPEG video streams on
desktop PC's and Television monitors located anywhere in the world.
Recording vs. Archiving
MPEG-2 encoders behave differently when mixed models are present in the same enclosure.
For example when there is a WM encoder in Slot1 and an MPEG-2 encoder in Slot2, the
MPEG-2 recorder becomes an archiver and not a recorder. (An archiver can only record from
an associated encoder whereas a recorder can record from an encoder, a decoder, or from the
network.) This section explains in detail how the MPEG-2 encoder works when functioning
as a recorder (see VBStar Record
on page 105). For an explanation of how the MPEG-2
encoder works when functioning as an archiver, see "Configuration: Encoder > Archiver" in
the WM Appliance Admin Guide.
VBStar Pump
MPEG-2 video can be played directly from the internal hard disk or streamed from the
VBrick to an unlimited number of desktops over an Ethernet/IP. The term "Pump" is used
in connection with VBStar screens to indicate that video stored on the hard drive may be
transmitted similar to the way VBrick delivers live video. Any file selected using any of the
management interfaces can be sent to any address on the network. To view the file locally, it
is necessary to specify the file and enter an appropriate multicast or unicast address into the
pump destination address field. A file may be pumped in batch mode or single file mode. The
designated file or batch may be pumped once or continuously. The file may also be pumped
automatically as soon as it is received through FTP.
Note In mixed models with an MPEG-2 encoder in Slot1 and an MPEG-4 encoder in
Slot2, you can only record from the MPEG-2 encoder.
