It was developed for use with VCRs in ENG, broadcast, and post-production environments, correcting time base errors and synchronizing non-synchronous video signals for mixing, editing, or broadcast.<br /> <br /> The unit digitizes incoming composite video into its luma and chroma components at 8-bit precision — at greater than 8 MHz for luma and greater than 4 MHz for chroma — storing up to 525 horizontal lines in RAM and reading data back at a stable clock rate. The read clock is generated by a VCO locked either to an external genlock reference or to an internal sync generator. After reconstruction, the output video has a residual time base error of ±15 ns and is RS-170A compatible when genlocked.<br /> <br /> A full-frame memory enables freeze frame and freeze field (field 1 or field 2) functions. Variable frame and field strobe modes allow adjustable-rate strobing. The Drop-Out Corrector (DOC) monitors the RF output of the connected VCR; when a dropout is detected, the affected line is replaced with data from the previous line. The unit features auto freeze when a &quot;bad field&quot; condition is detected (loss of horizontal sync, missing or incorrect vertical sync, or tape head switch events), with individual auto freeze functions defeatable via internal DIP switches.<br /> <br /> Digital effects — posterization, sepia, and mosaic — are accessible via pull-out front panel knobs and can be combined with freeze and strobe. Processing amplifier controls for video level, setup level, chroma, and hue are also pull-out/push-in knobs. The unit fits a single rack unit (1U) in a standard 19-inch rack.<br /> |height=1.75 in<br /> |width=19 in<br /> |depth=15 in<br /> |weight=16 lb<br /> }}<br /> <br /> {{AV TBC<br /> |type=Line TBC<br /> |buffer_size=525 horizontal lines<br /> |notes=8-bit luma and chroma; 4.2 MHz bandwidth; residual time base error ±15 ns; SNR 58 dB<br /> }}<br /> {{AV TBC<br /> |type=Frame synchronizer<br /> |buffer_size=525 lines (full frame)<br /> |notes=Freeze frame, freeze field 1/2, variable frame/field strobe; auto freeze on bad field detection<br /> }}<br /> {{AV input<br /> |label=Video In<br /> |signal=Composite (CVBS)<br /> |connector=BNC<br /> |count=1<br /> |audio=None<br /> |location=rear<br /> }}<br /> {{AV input<br /> |label=Genlock In<br /> |signal=Composite (CVBS)<br /> |connector=BNC<br /> |count=1<br /> |audio=None<br /> |location=rear<br /> |notes=Hi-Z loop-through; two BNC connectors (J5/J6) for looping genlock reference to additional equipment<br /> }}<br /> {{AV output<br /> |label=Video Out 1<br /> |output_type=Video<br /> |signal=Composite (CVBS)<br /> |connector=BNC<br /> |count=1<br /> |location=rear<br /> |notes=Primary output; passes input video directly in bypass mode (power ON, bypass switch ON)<br /> }}<br /> {{AV output<br /> |label=Video Out 2<br /> |output_type=Video<br /> |signal=Composite (CVBS)<br /> |connector=BNC<br /> |count=1<br /> |location=rear<br /> |notes=Secondary output; carries TBC-corrected video in all operating modes<br /> }}<br /> {{AV voltage range<br /> |voltage_min=117<br /> |voltage_max=117<br /> }}<br /> {{AV link<br /> |link_type=Manufacturer<br /> |link_source=Prime Image<br /> |link_url=https://web.archive.org/web/19990128203417/http://www.primeimageinc.com/TBC_SYNC.htm<br /> }}<br /> <br /> [[Category:Prime Image AV devices]]<br /> [[Category:Time base correctors and frame synchronizers]]</div>
