Replacing and Supplementing Satellite Distribution with IP

Media organisations have long used satellite distribution as a means of contributing and distributing video content. This is changing as distribution over unmanaged IP networks, such as the Internet, proves to be a cost efficient and effective alternative to satellite distribution.

The RIST protocol has been designed to ensure that high quality content can be transported over the Internet in a secure, reliable, and efficient way.

The RIST Main Profile incorporates robust encryption, using PSK and authentication. To improve the standard PSK encryption, RIST allows for dynamic key rotation every few seconds or more. Using RIST for video over IP delivery improves reliability by way of load balancing the RIST server. It also enables an increased number of clients to be supported, as well as an increase in geo separation by going to the private or public cloud. The Main Profile features the ability to add and drop clients using key exchange on the fly. It can reduce the overhead using null packet deletion to reduce the overhead going to the receivers.

It is also possible to take a hybrid approach and continue to use satellite for the main broadcast delivery method with IP using RIST as the back-up or supplementary distribution method.

This video demonstrates how RIST can be used to replace or to supplement satellite as a distribution method with IP.
