Solution Overview - cDVR Features
Recorder
The Recorder provides live-to-file video capture of multi-bit rate (MBR) video. By recording the MBR
video and audio of every channel to a mezzanine storage, subscribers have the ability to create
personal recording of events in the future or even events that have already occurred in the past.
Since this content is saved as ABR in the network, the play out is available for any multi-screen device.
Recording
Modes
Two recording modes are offered:
•
Continuous Recording
(CR) — any or all channels are recorded to mezzanine format. Subscribers’
events can be abstracted from these recordings and stitched together based on the subscriber
start and end times.
•
Event Based Recording
(EBR) — designed for systems in which storage space is constrained, EBR
allows subscribers to define what is recorded based on subscriber start and end time.
Recording
Function
The Recorder operates as an independent component, which provides the following benefits:
•
The JITP output component can scale in a more practical manner;
•
End client packaging can utilize more diverse use cases.
Telurio
TM
Recording
Manager
The Telurio Recording Manager (RM) acts as the central management point for the cDVR solution;
managing assets, storage, recordings and events.
As users select events to record from their EPG, these selections are routed through the operator’s
middleware device to the RM. With the RM’s easy-to-integrate RESTful APIs, operators are not locked
into a single middleware vendor.
Content
Storage
By storing the recorded content once in a common format, an overall smaller footprint of storage
space is realized. All video, audio and data are captured to ensure the richness of the entire stream is
available for packaging to the end client. This single stored format is then packaged on-the-fly based
on the client’s device as requested.
Since the recorded content is in a common, non-proprietary format (HLSv4), use of the recorded
content is not restricted. For those operators concerned with security of the recorded content, the
mezzanine content can be encrypted.
Storage
Types
Imagine Communications’ cDVR solution offers several storage options to meet the various operator
preferences:
