68 Adjustments and Settings for Recording: Setting Time DataAs a result of processing to convert the video captured bythe imaging devices from a progressive signal to an interlacesignal, video signal delays will occur in the camera.Since time is required for making the 2:3 pull-down from the24P frame, there is a video signal delay in the camera.When recording from a device that can record imageswithout a delay and the unit is connected in parallel, it isnecessary to synchronize the time code. To set this timing,open the screen from the MAIN OPERATIONpage and set it in the TC VIDEO SYNCHRO item.Set by referring to the connection example.Example 3: When the unit and an external device arelocked to the external time code generator,which is connected externally, and whensimultaneous recording is made by using theTC OUT output signals.¡NoteIn the 1080-23.98PsF or 1080-24PsF mode, set the23.98PsF or 24PsF HD signal as the reference signal andinput a 24 frame time code to the TC IN input.If the VTR is capable of recording the HD SDI time code, it ispossible to receive the time code output from the HD SDI A ·B output, and synchronously record video with the timecode. In this case, it is not necessary to supply a time codeoutput signal to the VTR.Example 4:When the unit and an external device are locked to theexternal time code generator and when several units ofthe camera are connected in a cascade configuration.Setting of the TC VIDEO SYNCHRO itemItem Variablerange RemarksTC VIDEOSYNCHRO0123For setting to correct the time codeaccording to the delay of video signals.0: Do not correct.1: To delay the time code to beinput according to the timing ofthe video images.2: To forward the time code to beoutput according to the timing ofthe video images.3: To delay the time code to beinput and forward the time codeto be output, respectively,according to the timing of thevideo images.TCGTC OUTTC OUTTC INREF INTC INTC INGENLOCK INVIDEO INHD SDI INAJ-HPX2700DATReference video signalExternal time code generatorDevice that records images without adelaySettings of the TC VIDEOSYNCHRO item: 1MON OUTorHD SDI A · B VTR etc.TCGTC OUTTC OUTTC INTC INGENLOCK INAJ-HPX2700TC INAJ-HPX2700GENLOCK INGENLOCK INDATTC OUTTC INAJ-HPX2700TC OUTReference video signalExternal time code generatorDevice that records images without adelaySettings of the TCVIDEO SYNCHROitem: 32nd unit and later Settings of the TCVIDEO SYNCHROitem: 31st unit and laterSettings of the TCVIDEO SYNCHROitem: 3
