a video signal transmitting method comprising : a sending method including the steps of : dividing an analog video signal in a unit corresponding to integer times of a number of bits composing an information field of one packet in packet transmission and converting into a digital video signal , forming a digitalized video signal into a plurality of packets , forming a plurality of packets into a first packet block in m lines × n columns , adding an error correction code which corrects a longitudinal error of data in a first packet block as a second packet block in p lines × n columns in an th line and thereafter , and sending a packet ; and a receiving method including the steps of : recomposing the same packet block as that composed on a sending side from plurality of received packets , recovering a video signal with packet loss information from an exchange and an error correction code formed into a packet , and regenerating an analog video signal from a digital video signal after recovery .
