Panasonic AG-7700E Operating Instructions Manual

Time codeThe “time code,” which is based on the time code signal generated by the time code signal generator, recorded ontape, and read out by the time code signal reader, is used to display absolute positions on the tape in units of“hours:minutes:seconds:frames.” Knowing an absolute position makes it possible to conduct editing accurately andsearch operations speedily.There are two types of time codes: LTC (longitudinal time code) and VITC (vertical interval time code). The LTC isrecorded on the tape’s normal audio CH2 track. It is used to record the position information on the tape and user’s bitinformation.The VITC is recorded in the vertical blanking period of the video signals so that even without using the normal audioC2 track, it is used to record the information regarding position on the tape and user’s bit information.- |————_L¢ time code (audio CH2)Audio CH1Video signal and Hi-Fi audioVITC time codeMM MTN UO Control signalThe time code itself is indicated on the display and superimposed on the TV monitor.LTCR 00:07:04:24Ladle: clesTime code mode Hours Minutes Seconds’ FramesUser’s bitAmong the time code signals, the “user’s bit” is an information released to the user.
