59/60

FREQ*1

The 59.94 Hz or 60 Hz system frequency is

 

selected.

 

0001

50i/25P*2

 

The 50 Hz or 25 PsF system frequency is

 

selected.

 

At this setting, the 1080/25 PsF format signals

 

can be recorded and played back in the same

 

way as with the 1080/50i format.

 

0002

23/24

 

The 23.98 Hz or 24 Hz system frequency is

 

selected.

 

0003

25(HD)

 

The 25 Hz system frequency is selected.

 

However, SD SDI output and analog composite

 

output are delayed with respect to HD SDI output

 

by about one field.

 

0004

25(SD)

The 25 Hz system frequency is selected. However, the black signal is output from HD SDI output.

0005 50(HD)

The 50 Hz system frequency is selected. However, SD SDI output and analog composite output are delayed with respect to HD SDI output by about one field.

0006 50(SD)

The 50 Hz system frequency is selected.

However, the black signal is output from HD SDI

output.

Description of setting

 

 

26

For selecting the output whose HD output

HD SYS H ADV

phase is to be advanced by 90H in relation to

the SD output.

 

0000

0H

 

Both the HD and SD signals are output in phase

 

with the HD and SD REF output signals.

 

0001

90H

 

The HD signals are output at a phase advanced

 

by 90H from the SD output signals.

 

When the SD REF signal is input, the REF input

 

and SD output are in-phase, and when the HD

 

REF signal is input, the REF input and HD output

 

are inphase.

 

<Notes>

 

 

z The audio signals and TC signal are output in

 

phase with the HD output.

 

z With the 720p format, there is a phase difference

 

of 120H between them.

system file lock mode.

Even if [ON] is selected, the file is overwritten when

 

the system file is retrieved from an SD memory

 

card.

 

 

 

 

*1System switching

zSome of the system menu and setup menu items each have different settings for different operation modes [59/60 Hz, 50 Hz, 23/24 Hz, 25 Hz (HD or SD) and 50 Hz (HD or SD)]. These settings are saved separately.

(This concerns those items whose settings were described for each operation mode on the system menu and setup menu tables.)

zFor further details, refer to <Menu management accompanying switching the system frequency> on page 113.

zSince this VTR becomes a playback-only unit when the 23/24 Hz, 25 Hz (HD or SD) or 50 Hz (HD or SD) mode has been selected, the functions relating to EE, recording and editing are all set to the inhibited status. Neither is it possible to select CTL in such a case.

(The related menus and function buttons are not displayed, and operation is prohibited.)

For the instant when the tape begins to run at the 1k speed such as when it starts playing from the STOP status, the image is disrupted and the sound is muted for several frames because the tape is being synchronized with the REF input.

The underlining (__) denotes the factory setting mode.
