Features

Bi-directional Transcoding PAL (B, G, I), PAL N.
Five-line high performance adaptive comb filter. Bandwidth 6 MHz.
10 bit precision, 4:2:2 processing and conversion, with oversampling.
Differential composite video input.
Four composite video outputs.
User friendly control panel with graphic lighted display, keyboard, and extensive selection and enhancement facilities.
Luma gain, chroma gain and black level controls.
Horizontal and vertical (aperture correction) enhancers.
Selectable input filter.
Selectable luminance bandwidth.
Switchable bypass in the vertical interval. Allows the pass of the “closed-caption” signals.
Selection of lock reference: output subcarrier locked to horizontal, to the input subcarrier or to internal reference.
Selection of output signal in the event of input signal loss or error.
Programmable test signal patterns
Dual redundant power supply and monitor of power supplies (FD option).
Specially recommended as PAL B to PAL N transcoder for broadcasting signals.
