Sat-IP
SAT>IP (or Sat-IP) specifies an IP-based client–server communication protocol for a TV gateway in which SAT>IP servers, connected to one or more DVB broadcast sources, send the program selected and requested by a SAT>IP client over an IP-based local area network in either unicast for the one requesting client or multicast in one datastream for several SAT>IP clients. While the system, originating from the DBS satellite operator SES, is originally geared towards receiving and distributing satellite broadcasts in DVB-S or DVB-S2 encoding, SAT>IP also specifies formats for the SAT>IP client request to specify programs broadcast via DVB-C and DVB-T. Only the SAT>IP servers need tuning hardware and software specific to the DVB-broadcast system(s) being used; SAT>IP clients can be any IP-enabled client multimedia device – Tablets, PCs, laptops, Smartphones, “connected” TVs, video game consoles, media players or others.
