Burnt In Time Code2 Row display showing (Longitudinal) Time Value & User Bits
LTC + VITC=BITC
A 1U rackmount unit that reads both Longitudinal and Vertical Interval Timecode. Decoded LTC/VITC Time & User values are displayed on the front panel LED display, and may be inserted onto a video signal for subsequent recording or display on a TV monitor; either as:-
An 8 digit (TIME or USER Bit) or
A 16 digit (TIME & USER Bit).
LONGITUDINAL TIMECODE
TCR-300 card decodes LTC at any speed between 1/50 - 220x normal speed, subject to satisfactory quality of the recovered off tape code. The balanced input is high impedance, accepting levels between -12dBV.7 & +20 dB The input may be used balanced or unbalanced, as required.
.
.
VERTICAL INTERVAL TIMECODE
TCR-300 automatically detects and decodes the first VITC data of the vertical interval, without any adjustment. Detected VITC lines are CRC verified before being decoded. An internal VITC decode adjustment can provide a measure of compensation for phase and amplitude errors on the input video signal.
.
.
AUTOMATIC CHANGE-OVER
Preserving low frame rate performance, TCR-300 changes over automatically to VITC data when the LTC stream drops below 0.5 normal speed. This operation is inhibited if VITC is either absent or corrupt.
BURNT IN TIME CODE : TIME and/or USER Bits, with AUTO SIZING
TCR-300 inserts the decoded data into a standard video signal. White characters are surrounded with character-shaped black masks, maximizing visibility on all possible program material. The display may be positioned at the top or the bottom of the screen, and be muted as desired. Either a single row, or a dual row of characters, may be displayed on the screen. Selection is also possible between TIME or USER Bits only. Character height is automatically reduced when both rows are displayed simultaneously. With 525 signals, automatic compensation is applied to the vertical position of BITC screen characters, due to the shorter field.
