The document summarizes an engineering thesis that designed and implemented a headend and IP infrastructure to transmit television signals over a network. The headend received channels from three free-to-air multiplexes using DVB-T receivers. The signals were retransmitted using multicast protocols over a network built with Allied Telesis switches supporting IGMP. Users could then watch digital TV through a Stalker middleware interface and MAG 250 decoder. The paper also reviewed audio/video compression methods, conditional access systems, available signal sources, and IP transmission protocols.
