PENC-3005 series SDI-to-PAL/SECAM encoders |
PROFLEX™ PENC-3005 series SDI-to-PAL/SECAM/YC encoders accept D1 270Mbit SDI signal to encode into PAL, SECAM or Y/C.
Features
- 10-bits digital video processing
- SNR better than 63dB
- broadcast quality DAC at 54MHz
- adaptive notch filter (SECAM only)
- flat luminance channel frequency response: roll-off less than -0.2dB at 5,75MHz
- full chrominance channel bandwith
- two modes of PAL color subcarrier generation:
- autonomous, ITU-R BT.470-2 compliant
- external REF signal driven
- PAL color subcarrier phase manual adjustment: 360° with 0,3° steps
- PAL output signal phase adjustment to the external REF signal capability:
- built-in VITS generator with full-field insertion capability
- built-in colorbar generator
