TV Network Protocol

From Wikipedia, the free encyclopedia

The TV Network Protocol or TVNP as it is more commonly referred to is an open network protocol developed to enable CCTV systems from any manufacturer to be integrated into an existing CCTV network. It provides high levels of support for audio routing, video routing and camera control.

The protocol was developed by Philips Projects (now Tyco Integrated Systems). Tyco acts as the standards and approvals house for companies who want to implement the protocol.

The protocol's roots can be traced back to the Highways Agency HDLC standard. It is the property of TfL and is independent of any supplier. Currently there are about half-a-dozen manufacturers who have a partial or full TVNP interface.
