INTRODUCTION
Model 5950-SID VITC Reader / Source ID Decoder Manual
The model
VITC Reader / Source ID Decoder combines the latest
5950-SID
LSI technology with sophisticated microcontroller firmware to provide a
powerful, flexible reader system. The model
multi-function character inserter to display the decoded source ID
information. A 12 digit alphanumeric display can be quickly delegated to
show the required data.
The 5950-SID has been designed to decode Source ID/status information
which has been encoded by source ID Encoders such as the model 8025-
SIE. The VTR time is encoded in the usual way for sources that have
timecode associated with them.
cameras, the 5950-SID senses codes in the user bits to automatically blank
the time display on the character inserter.
message and a 3 digit source number are encoded into the user bits. For
VTR sources, VTR status is also encoded into the user bits. For sources
that do not have encoded status information, the 5950-SID automatically
blanks the status display.
The model
5950-SID
and therefore, requires no external signals other than the video signal itself.
The VITC reader's line range can be easily programmed from the front
panel, thus permitting recovery of specific VITC data where multiple sets
have been recorded.
The high resolution character inserter provides two independently
positionable windows to show time and source ID/status (decoded from the
user bits) simultaneously. Three character sizes and the choice of white or
black characters with or without contrasting background mask are selected
from the front panel.
When displaying data recovered from a VITC source, the 'lookahead'
compensation can be turned off, allowing field accurate burn-ins of edited
material. The field number sequence will be displayed to the right of the
frames display. When the data being read was recorded in the non colour
frame mode, the field number sequence will be 1,2,1, etc. (1,2,3,4,1, etc.
for PAL). When the reader data was recorded in the colour frame mode,
the field number sequence will be 1,2,3,4,1, etc. (1,2,3,4,5,6,7,8,1, etc. for
PAL).
The Character inserter provides an on screen programming menu system,
which is used to configure the various operating modes. The use of drop
down menus, and dedicated programming keys, allows the model
to be conveniently configured for particular customer requirements.
