External Sync Function; Important - Pioneer DVD-V8000 Mode D'emploi

07 Function for Commercial Use

External sync function

The DVD-V8000 is able to accept an external sync signal (black
burst), allowing the video output to be synchronized with ex-
ternal signals. (External sync does not operate when playing
discs other than DVDs.)
By means of this function, video switching timing can be per-
formed without the need for connecting a TBC (time base
corrector), thus allowing switching between images without
causing disruption (vertical roll).
To turn this function ON, switch the ADV. SETUP menu's
[EXTERNAL SYNC] setting from [OFF] (default) to match the
television format of the disc being played back ([NTSC] or
[PAL]). At the same time, set the rear panel TV SYSTEM
switch to match the disc being played back (NTSC or PAL).
When synchronizing a single player alone, set its terminator
switch to ON. (Factory default position: ON)
Synchronizing two or more players
¶ When a single sync generator be used to input sync sig-
nals to two or more players, set the external sync termi-
nator switch for the terminal player to ON, and those for
other connected players to OFF.

Important

¶ When the external sync function is set to ON, discs other
than DVDs cannot be played back.
¶ The black burst signal's subcarrier component is not locked.
¶ The video signals from video output connectors will be
disrupted during the approximate 5 seconds required for
the external sync signal to lock.
¶ Input the external sync signal before beginning DVD play-
back, since it will not operate if it is input after playback
begins.
¶ Depending on the sync generator and cables used, con-
necting numerous players may result in attenuation of the
external sync signal, resulting in malfunction.(see Fig.1)

Differences between Mode 1 and Mode 2
When the ADV.SETUP menu's EXTERNAL SYNC is used to
select NTSC Mode 1 and PAL Mode 1, the unit's video signal
output is delayed by 1 field with respect to the external sync
signal.
When NTSC Mode 2 and PAL Mode 2 are selected, no delay
is produced with respect to the external sync signal, but the
following functional restrictions apply:
¶ SETUP's Video Adjust command is not supported.
¶ DVI output is OFF.
¶ Component output is interlaced, and progressive output
is not supported.

Component output
In either Mode 1 or Mode 2, synchronized output from two
DVD-V8000 units with the same settings is achieved without
timing deviation.
When switching between the output of a video component
other than the DVD-V8000, if the 1-field delay is problematic,
select Mode 2.
