Redundancy
To allow for the highest level of redundancy which minimizes downtime, Imagine Communications’
cDVR solution provides node-level, 1+1 active/standby redundancy for the RM in which an RM
redundancy group contains a Primary (or Active)
RM
and a Standby RM. The redundancy group
provides a failover capability from the active RM to the standby RM. Each time the configuration
database for the active
RM
is updated, the standby RM synchronizes its configuration database with
the active RM’s configuration database.

Storage
Management
One of the capabilities of the RM is the ability to manage storage. Operators define storage
management parameters based on available disk space and the RM will control the recording and
deletion of content accordingly. These parameters include:
•
Days to continuously record live channels
•
Time to keep unreferenced segments
•
Time to keep assets
The Recorder functionality is integrated with key storage technologies as described in the section titled,

RM
WebGUI
The RM WebGUI provides the user interface to the RM, Recorder, and JITP server by allowing
configuration and monitoring of channels, monitoring managed nodes, and scheduling recording. The
RM WebGUI is an integrated interface application that is automatically installed with the RM software
image and accessed through the RM IP address. RM also performs cDVR management and
configuration of the Recorder and JITP/Stitcher.

Shared
Copy
for
Continuous
Record
In a
shared copy
cDVR environment, a single copy of a recorded program is stored in the network and
can be accessed by multiple subscribers. In a
private copy
cDVR environment, one private copy of a
program is available only to the subscriber requesting it. If two subscribers wish to view the same
program, a separate copy (i.e., two copies) must be available for each requesting subscriber. Private
copy allows service providers to deliver cloud-based DVR content to locations in which usage rights
require private copies of programming per subscriber.
The RM has the ability to create either shared or private copy recordings from recordings made
continuously.
