TCMD010 - BALBOX Time-code Monitor Display. VITC


The BALBOX TCMD010 accepts an SDI signal and provides two re-clocked SDI outputs and two analogue composite (or Y/C) outputs. If VITC is present in the SDI, it is displayed as an overlay on the composite outputs. The user may select the line carrying VITC, and the position of the on-screen display.

The BALBOX TCMD010 and TCMD011 provide
conversion of serial digital video signals to composite
analogue video with in-monitor display of time-code. The
user may choose the position of the overlaid time-code
display to be either at the top or bottom of the picture
(user-selectable).

Two composite outputs are provided and these can be
switched to YC output mode.

The SDI input has automatic cable equalisation for up to
250m of coaxial cable and provides two re-clocked SDI
outputs. The two SDI outputs do not display time-code.

TCMD010 displays VITC present on the SDI input.
TCMD011 allows the user to display VITC or an
externally applied LTC feed.

User control is through DIP and rotary switches at the
front of the unit.

The user can choose to pass or blank the VBI and also
set to produce either colour black or a noise signal on
the composite outputs on loss of the input source.

The unit has an integrated mains power supply
(universal 90 to 250Vac range) with filtered IEC
connector for safe and reliable installation.

Both models of the TCMD are housed in robust steel
cases, and may be mounted with other BALBOX units is
a simple 1U tray.
