METHOD AND SYSTEM FOR PRACTICING IPTV EDUCATION BROADCASTING SERVICE

摘要

A method and a system for practicing an IPTV education broadcasting service by checking a correct answer are provided to check/analyze a correct answer rate related to question explanation, thereby effectively producing statistical data. A baseband system(205) performs frame synchronization of a broadcasting signal. A data broadcasting system(235) produces data and PSI data for data broadcasting. A multiplexing system(210) multiplexes image signal/voice signal and the data/PSI data for data broadcasting. The multiplexing system IP-packetizes a transport stream. A network switch system(215) transmits the transport stream to an IPTV subscriber terminal through an IP network in a multicasting mode. A problem solving system(250) performs statistics by checking/analyzing percentage of correct answers related to question explanation of an education broadcasting lecture according to a request of an IPTV subscriber.
