    time base corrector
  • infinite window time base corrector using 8 bit 4:2:2 CCIR-601 professional quality all digital video signal processing
  • realtime 24 bit video framegrabber / framebuffer for use as a digital video stillstore or signal generator
  • full transcoding between Composite and Y/C (SVHS) input and Composite and Y/C (SVHS) output
  • full processing amplifier (ProcAmp) control for correcting or adjusting incoming video on the fly quickly and professionally (hue, brightness, contrast, saturation)
  • realtime programmable video special effects generator featuring solarization, strobing, pseudo colour, monochrome effects, and more
  • NTSC / PAL / SECAM signal standards conversion to NTSC / PAL for integration into worldwide video environments automatically
  • ImageFX: direct editing and manipulation in the framebuffer
  • optional full SMPTE / EBU timecode receiver / generator (encoding / decoding / striping) - VITC (Vertical Interval Time Code) and LTC (Longitudinal Time Code) can be read and written
  • optional digital comb filter (cleans up Composite for Y/C output and fixes cross colour by splitting the Composite signal into separate chroma and luma signals as if it were a true Y/C input) provides true wide band 5.5 MHz Composite video performance
  • inputs and outputs reside on an adaptor cable
    • inputs: Y/C, two Composite Video, external key signal, sync reference signal, Longitudinal Time Code (LTC)
    • outputs: Y/C, Composite Video, Longitudinal Time Code (LTC)
  • the Composite and Y/C inputs can be connected simultaneously and hot switched with software without having to play with cable connections
  • convert the two Composite inputs into a single Y/C input, providing two switchable Y/C inputs
  • up to five TBCPlus cards can be installed in a single Amiga and independently controlled
  • will not overload the power supply when the maximum of five TBCPlus units are installed
  • works in 30 Hz, 29.97 Hz, 25 Hz, 24 Hz drop frame and color frame modes, can put a SMPTE burn-in window anywhere over the video
    memory
  • two 30 pin SIMM sockets for frame buffer memory - 1 MB installed as standard, expandable to 2 MB for improving special effects
  • two 64 pin SIMM sockets for 4 or 8 MB standard Zorro II Fast RAM - accepts only 4 MB GVP SIMMs
  • the Fast RAM expansion has nothing to do with the performance of the TBC Plus, it doesn't increase the frame buffer capacity - it is meant for A3000 and A4000 machines which may have problems with Zorro II DMA to Chip RAM
