● The Head-end was upgraded for DTT. This included a new multiplexing equipment as well as DVB-T2 MI adaption equipment. The system supports Mux 1, Mux 2 and regionalised content.
● After laboratory Proof of Concept, a pilot DTH compatibility system was established for the Gauteng SFN, in order to prove stable operation in a live environment. The system will enable efficient use of transponder capacity for both DTT and DTH.
● This technology is currently under testing phase with completion planned by the end of the Financial Year, wherein the conventional DTT (DVB-T2 MI) system is fully established and operational. Continued testing is under evaluation with the technology partner.

DIGITAL TERRESTRIAL TELEVISIONBroadcaster Issues – Commercial and Legal
11
BROADCASTER STATUS
SABC An agreement was reached on the DTT rate card. Currently negotiating the Master Transmission Agreement (MTA).
etv The negotiation on the rate card is at a mature stage. There is an agreement on the terms and conditions of Master Transmission Agreement.
MNET Negotiations are ongoing.
Community Broadcasters
In the Analogue environment most Community Broadcaster are broadcasting on one transmitter. As a result of the Frequency Plan the DTT network has multiple transmitters for a Community Broadcaster. This will make the network unaffordable to the Community Broadcasters. Sentech has engaged with the DoC to seek funding for this.
