PVR and Home Networking

recording content
Using the UPnP standard for discovery and control of distributed devices within the home media network it is possible to provide true home networking functionality using PVRs, Digital Media Adapters (DMA) as well as PC clients within a seamless network that allows transparent access to stored media assets within a home network.

The following figure shows an example for such a network:



The figure on the right implements the following scenario:

The PVR implements a UPnP server that provides the recorded content to the overall network Live TV streams are provided by the PVR to the overall network The PC hosts a number of media assets (audio, video, pictures) and provides this information to the overall network The DMA is able to access content from the PVR (recorded TV contents, live TV channels) The PC


The UPnP implementation on the PVR and DMA systems provided by DiscVision implement the following features:

UPnP server is available on PVR systems providing access to:

Recorded audio, video streams
Live TV streams
Pictures, MP3, Videos stored on the hard disk of the PVR or any HDD attached via USB2.0
UPnP client and UPnP control is available on PVR systems and DMAs UPnP client can be deactivated so that a remote UPnP control cannot submit streams to the client UPnP download manager is available on PVR and DMA. The download manager takes up the discovery and eventing mechanisms of UPnP and implements a full file download manager:
Content files can be transferred between different storage devices, i.e. from PC to PVR or from PVR1 to PVR2. The download manager allows preemptive communication and will automatically restart a failed transmission at the last successfully transmitted data packet.
Using the download manager, recordings can be downloaded to a PC where they can be re-structured (segmentation) and archived onto DVD using the PVRpilot tool.
A large number of files can be handled in parallel by the download manager allowing varying priorities for the different streams that are handled.
Ongoing transmissions can be paused, priorities can be changed, jobs can be resumed, and much more operations can be done on an active download job.
