Broadcast coming form the National Head-End distributes using MPEG-2 encoding to the video service nodes. Distribution over the access network is done through DSLAM (Digital Subscriber Line Access Multiplexer) and FTTH(Fiber-to-the-Home). Subscriber STB acts as the terminating interface for the network providing output to the television. For IPTV, teh channel content can be of standard or high definition.
