The trusted advisor for Network Digital Video Recording (nDVR)


In the course of the last five years, TV consumption has changed drastically. Viewers expect to watch TV anywhere, anytime, from any type of device. Recording is still ranked as the second most attractive service after live TV.  However, traditional Personal Video Recording (PVR) services with a local hard drive are outdated. Today, the new type of TV consumer expects to record and consume TV on the go from any device, with access a large library of videos.


Network Digital Video Recording (nDVR) services will allow us to leverage the power of the cloud to acquire infinite scalability and elasticity, to manage recording peaks and the need for increased recording space. It will also increase customer stickiness and optimize the cost of operations by limiting the maintenance of the MVPD customers’ local hard drives. 

There are some key insights that Telcos and Media companies should be aware of when selecting a nDVR solution:


Integration complexity

Network or Cloud DVR is a strategic platform for mobile and on-demand TV distribution. Customers can use the nDVR system in an existing TV content management system while keeping options to evolve or replace it according to business needs, such as creating a new inventory of targeted advertising.


Architecture flexibility

The nDVR solution architecture must be adaptable to changes in usage models while delivering at petabyte scale, and at the same time anticipating storage needs. The demands on storage, processing and throughput are huge. Strategically designing the infrastructure as well as video and virtualization is another benefit for customers.


Evolution strategy- private and shared copy model to be prepared for the unknown

The nDVR solution architecture will support current business requirements: private or shared copyrights requirements while being ready to accommodate new needs.

In the “private copy” model every time a customer records a program, the Cloud DVR system creates a new file that contains this piece of content. For every recording, even if this is the same piece of content recorded by two different users, a separate file is created and stored. In this configuration the need for storage will grow linearly with the number of recording and subscribers.


In the ‘shared copy’ model, different users record the same content, a  single copy of this content is stored. In this case, there is a huge optimization of storage space as the content is stored once for all.  This ‘shared copy’ approach works well in the case of Electronic Program Guide (EPG) based recording where the start and end times are the same for all customers recording the same show. 


The HP TVE Content Delivery nDVR solution is natively ready to support both models. Each model has been conceived to optimize storage. HP acknowledges that the model can change and its solution is ready for future MVPD needs.



nDVR Services and much more  


Today viewers experience goes beyond recording on the network. At HP we acknowledge this new model of consumption and our HP TV Everywhere nDVR solution offers an ultimate TV network recording and OTT playout experience:


  • OTT Play live TV is the ultimate live TV experience including time shift services  such as start over  catch up,  pause and resume TV services from any device
  • Network DVR is the complete on-the-go recording service set. Users can schedule recordings based on time or event for scheduled or live TV. Synchronization with the EPG is performed in real time. Actions such as record, cancel, stop, delete, of scheduled or live program recordings are available from any device. Simultaneous recording of several channels is also possible.


HP TVE Content Delivery nDVR solution: a flexible architecture


The HP nDVR solution is designed to be adaptable. It supports the evolution of usage patterns, the legal and contractual framework, video technologies and business strategies.  It can also scale linearly with MVPD’s growing service and usage needs. This is possible via a combination of software modules and IT infrastructure that can scale cost effectively. In this architecture, each module has a specific functionality: control, record, store, cache, transcode, package, playout. The architecture is modular and modules can be added based on the MVPD’s needs.


 In the share copy model, the HP nDVR solution takes advantage of possibilities of packaging on the fly. Each chunk is stored in a mezzanine format to provide the ability to support any new playout format. Furthermore, each chunk can be accessed by multiple users enabling MVPD to optimize storage and deliver a quality experience with content resilience at petabyte scale.


NFV adoption: Operators may also want to take advantage of Network Functions Virtualization (NFV) to increase agility and reduce operating costs.
