The treatment and digitized memory of U-matic tape information by the application of some electronic circuit in Betacam videois introduced,and this could be of a certain practical value with the aim to rescuing precious historical materials.Time basic shaking could be removed once the simultaneous interference is cleared for TBC treatment of re-shown screen signal in Betacam video.On the other hand,the combination of 1H delay line and pulse shift matrix solves information loss caused by tape backwardness through the way of DOC circuit in Betacam video.
