Communications protocol to transport satellite delivered signals over IP networks
| Published By | Publication Date | Number of Pages |
| BSI | 2014 | 82 |
This European Standard describes the SAT>IP communication protocol. It enables a SAT>IP server to forward satellite delivered signals to SAT>IP clients over IP networks. The typical use case would be the transport of television programs that were received from the satellite by the SAT>IP server to the SAT>IP client via the IP network. SAT>IP specifies a control protocol as well as the media transport (Figure 1).
SAT>IP is not a device specification.
The SAT>IP protocol distinguishes between SAT>IP clients and SAT>IP servers.
SAT>IP Clients
SAT>IP clients may reside in set-top boxes equipped with an IP interface or may be implemented as software applications running on programmable hardware such as Tablets, PCs, Smartphones, Connected Televisions.
SAT>IP Servers
SAT>IP servers may take various forms ranging from large MDU headends servicing whole buildings or communities to in-home IP multiswitches to simple IP adapters for a set-top box to, ultimately, IP LNBs.
Actual devices may be clients or servers or both depending on their feature set
