The CVR400D is a multistandard broadcast quality standards converter, synchronizer and timebase corrector.
With 12-bit sampling and capable of handling SDI, analog composite and Y/C signals, the CVR400D is a
powerful and versatile unit.
Standards conversion between 525 (NTSC) and 625 (PAL) line standards employs a powerful 20 point, 4 field,
5 line interpolation aperture to give smooth motion and maximum vertical resolution.

*Floating Mode - Without a reference the output will either free-run or lock to a stabilized input sync if operating in synchronize mode.
In this stabilized or ‘floating mode’ the output will always follow shortly after the input, so preventing lip-sync errors and frame drop/repeat.
The inputs are highly tolerant to unstable and noisy sources, while the synchronizer always creates correctly aligned images, even during
sync disturbances and asynchronous input switches. |
