Computer Graphics Video Encoder/Decoder Features
COMPUTER GRAPHICS VIDEO CODER/DECODERThe TTR140 is an economically priced coder/decoder designed for computer graphics applications. The unit will decode composite colour signals or YC (i.e. S-VHS or Hi-8) signals to RGBS, for frame grabbing - selection between the composite or YC input is made with a switch on the TTR140 module. The unit also accepts RGBS signals back from the graphics system and encodes them to composite or YC. With the exception of the reference sync input, the coder and decoder are completely independent of each other, allowing the unit to be used in other applications. The coder takes its reference from the decoder composite input or the YC input (selected by the switch on the module), but if a sync signal is fed to the Sync input the coder will line lock to this input, though it will still colour lock to the decoder input. The internal sync pulse generator ensures that an output Mixed Sync signal is always available from the decoder, even in the absence of an input. If it is required to time the coder output to another source, an H fine phase control and coarse and fine Subcarrier phasing controls are provided on the front of the TTR140 coder module. The coder includes an optional facility which allows an additional set of RGB inputs to be keyed over the "prime" inputs. This facility can also be used to simply switch between two sets of RGB inputs. The TTR140 is available as a Eurocard, housed in a 19" 1U rack unit which can accommodate up to two modules. The on-board power supply includes rectifiers and regulators allowing the power input to be either ac or dc. Specification

TTR GPI TriggerThe
TTR GPI matrix is based on 4 individual euro cards. The
heart of the system is a fully customer programmable Microprocessor card
with Non-Volatile memory back up. This card can be factory programmed to
your individual needs or we can provide software to allow full custom configuration. The
TTR GPI matrix is completely unique in as much as it lets you set up an
output by mapping a combination of inputs to it. These logical combinations
are sent to the switch through the programming interface and the matrix
latches the output state. The
matrix panel buttons are momentary and a virtual on /off state is kept in
the input range 128 – 255.
For example press button 1 on the panel and the input 1 will only be
momentary. The input 128 (virtual) will be set on and will stay on until
button 1 is pressed again. The virtual inputs can be read as real inputs and
used in the logical equations for the output programming. The
matrix is programmed by sending command packets to the device via a serial
interface. The
matrix will respond to each packet sent with a reply. If
the command is a status request the response will be a status reply. If
the command is a data request the matrix will respond with a data reply
packet and NO status reply etc. Specification
