Solution Overview - Solution Overview
•
Event Based Recording
—start and end times are fixed; a single file asset is stored per event,
which cannot be changed following the end of the recording.
•
Continuous Recording (CR)
—recording is abstracted (extracted from the original), which allows
start and end times to be edited before, during, and after the recording. Abstracted recording
allows for granularity, post-capture modification, and efficient use of storage.
•
Stitching
—when recording programs in CR mode, recordings are abstracted as a collection of
video fragments and grouped together (“stitched”) to create a single manifest file for requested
content.
•
Private Copy
—multiple recordings are stored and managed on a per subscriber basis, thus
allowing each subscriber a private copy of a program.
•
Shared Copy
—a recording is stored and managed one time in order for the same copy to be
available for any subscriber requesting it.

This section provides an overview of all components that are used in a service provider’s network when
implementing cDVR functionality. The first part of this section describes Imagine Communications’
cDVR components; the second part of this section describes additional components required for an
end-to-end cDVR network.
