whether or not record/play operations are underway. These streams are multicast to the network and
are available to applications on the network. When media is recorded, the K2 Summit system encodes
a high resolution clip and a low resolution proxy clip. The system keeps these clips associated so
any changes take effect simultaneously for both clips.
The GV STRATUS application accesses the low-resolution media over the network. When you
monitor the K2 Summit system SDI inputs and outputs, the application displays the live stream.
When you view an asset, the application displays the proxy representation of the asset. When you
edit an asset, the K2 Summit system makes your changes on both the proxy and the high resolution
asset.

HTTP server overview
The GV STRATUS system HTTP server provides access to low resolution proxy media.
The GV STRATUS application accesses the proxy using a HTTP URL. This supports efficient,
high-speed, and simultaneous access to proxy from multiple GV STRATUS clients. In addition, the
HTTP server supports remote access for GV STRATUS clients.
The HTTP server is on the GV STRATUS device designated the proxy server. This can be one of
the following devices, depending on the GV STRATUS system configuration:
• GV STRATUS Express server
• Proxy server
• Proxy Storage file system server
GV STRATUS components that create the low resolution proxy media must write the proxy files
to a location served by the HTTP server. This location is CIFS proxy share. The GV STRATUS
Control Panel creates the proxy share automatically when you configure Proxy Config settings. The
proxy share is shared with full permission granted to the internal system account, which by default
is GVAdmin. The K2 system and the Proxy Encoder create proxy media and therefore require this
CIFS access to the proxy share.
