Network Sources
VN-GLIMPSE RGB Graphics Sources
Applications running on remote computers can be ‘captured’ using VN-GLIMPSE.
This is ELECTROSONIC’s patented technology for the efficient lossless transportation of RGB
computer graphics over a standard IP network. VN-GLIMPSE can capture the desktop of the ‘source
computer’ using either of the following devices:
•
The VN-GLIMPSE SERVER is a software-based capture application and is directly installed
on the source computer. It is best suited to sources with low motion content. Note that during
a capture session some loss in speed/performance of the computer may be experienced. The
degree to which the computer will be affected is dependent on a number of factors, including
CPU speed and graphics card type. Refer to the VN-GLIMPSE SERVER User Guide for
further details.
•
The VN-GLIMPSE RGB ADAPTER is a hardware-based capture device and connects
between the keyboard, mouse and monitor on the source computer. It provides the same
graphics capture capability as the VN-GLIMPSE SERVER but does not have any adverse
effect on the speed/performance of the source computer. It is best suited to sources with low
to moderate motion content. Refer to the VN-GLIMPSE RGB ADAPTER User Guide for
further details.
The VN-QUANTUM Processor can connect to any VN-GLIMPSE source (via one of its network ports
– see page 32) and display it on the target display.
Note that the VN-QUANTUM CONNECT processor does not support the use of
the MEDIA I ad II ports.
Source Transfer
VN-GLIMPSE sources are delivered to VN-QUANTUM over an IP network. A DMA (Direct Memory
Access) process is used on an ES3311-2 Video Input Card to transfer source data from the PCI bus
to the RAPT bus. For this reason at least one ES3311-2 Card must be installed in every VN-
QUANTUM Card Frame.
NOTE: By using VN-GLIMPSE lossless compression, RGB data bandwidth is dramatically reduced
and results in more efficient use of the RAPT bus.
Note: The ES3304 VN-QUANTUM CONNECT processor does not support the use
of VN-GLIMPSE sources.
