Local Cache is a feature of ClickView Online that is designed to preserve internet bandwidth when users are accessing ClickView Online material within a specific network such as your institutions Local Area Network (LAN).
The bandwidth preservation that Local Cache allows for, is achieved by the ClickView Online video being served from your institutions local ClickView server, rather than being streamed from the internet when an end user accesses a ClickView Online video and is connected to your institutions network.
Local Cache is enabled and configured for use during your initial installation of ClickView Publisher and should be fully operational unless your institution has elected to manually disable this - ClickView strongly recommends that Local Cache is enabled where possible.
When a title is added to ClickView Publisher and subsequently uploaded to ClickView Online, the highest quality copy variant of the video is stored locally in the location that your ClickView Publisher setup has been configured to store your ClickView data on.
When an end user accesses ClickView Online, an attempt will be made to retrieve the video from your local ClickView Server; if the user is accesses ClickView Online on an interconnected network to where your institutions Local Cache data is stored, the video will be served from your local ClickView Server, rather than streamed from the internet. If the user is not connected to the same network that the Local Cache resides on, ClickView Online will ascertain this in a matter of milliseconds and will then proceed to serve the video from the users internet connection - as a result of this workflow, the end user should not experience any noticeable delays regardless of where they are accessing the video from.

Identifying that Local Cache is in Use
When playing a title back through ClickView Online, if the video is being served using the Local Cache functionality you will be able to see a ClickView icon in the bottom right hand corner of the playback window - as shown in the screenshot below:
If the ClickView icon is not present during initial playback, this indicates that the video is being accessed from the ClickView Online Cloud repository and not your institutions Local Cache setup.
Note: ClickView Local Cache is also fully supported on the available ClickView Desktop and Mobile Apps, however the Local Cache icon will not be present when playing material back through either of the above apps.
Configuring the Local Cache Server Address
Start the ClickView Publisher and go to 'Tools > Options > ClickView Online.'
ClickView Online will use either the Fully Qualified Domain Name (FQDN) or IP Address of the Publisher to access the Local Cache. In the example above, the Publisher's IP address has been specified.
In the event that the IP does not work, the FQDN can also be specified, as shown above. Contact technical support if any changes are made to this area.
Additionally, please ensure that the following registry entry is configured correctly:
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\ClickView\ClickView Home\LocalCacheEnabled = 1 (from 0).
If you have completed all of these checks and local cache is still not functioning correctly for you, please don't hesitate to contact ClickView Technical Support for assistance.
