DEC102

MECHANICAL:
Standard Crystal Vision module 100mm x 266mm. Weight: 200g. Power consumption: 6.25 watts
ANALOGUE INPUT:
Composite video input, 1 volt with syncs. 625 line PAL or 525 line NTSC. +/-2us adjustment of picture position from syncs
VIDEO SDI OUTPUT:
2 outputs SDI 270Mbit to EBU 3267-E & SMPTE 259M
ANALOGUE PERFORMANCE:
Frequency response with comb active: +/-0.3dB to 5.5MHz. Gain Error: <1%. Sampling: 10 bit precision 13.5Mb/s. Blanking: To analogue PAL/NTSC specifications, with selectable VBI blanking PAL lines 7 to 22 and 319 to 335. NTSC lines 10 to 20 and 273 to 282
LED INDICATION:
Power supplies on board, analogue input present, PAL/NTSC standard
LOCAL CONTROL:
Piano Switch control of comb on/off, setup on/off (NTSC only), VBI blanked or passed, cal or adjustable horizontal position (by board edge pot). Link selection of auto or manual PAL/NTSC standard selection

DEC102S

MECHANICAL:
Standard Crystal Vision module 100mm x 266mm. Weight: 200g. Power consumption: 8 watts
ANALOGUE INPUT:
Composite or Y/C video input, 1 volt with syncs. 625 line PAL or 525 line NTSC
VIDEO SDI OUTPUT:
2 outputs SDI 270Mbit to EBU 3267-E & SMPTE 259M with EDH
ANALOGUE REFERENCE:
Analogue Black and Burst, mixed syncs or video. Amplitude of syncs 150mV to 4V. Link on PCB selects 75ohm termination or high impedance with loop-through (via PCB)
AUDIO FOLLOW OUTPUT:
TTL output. Pulse length shows delay through store. Can provide control signal for audio delay systems
ANALOGUE PERFORMANCE:
Frequency response with comb active: +/-0.3dB to 5.5MHZ. Gain Error: <1%. Differential Phase and Gain in 10 bit mode: <1.5 degrees, <1.5%. Sampling: 10 bit precision 13.5Mb/s. 8 bit mode available for VHS style jittery input. Blanking: To analogue PAL/NTSC specifications, with selectable VBI blanking PAL lines 7 to 22 and 319 to 335. NTSC lines 10 to 20 and 273 to 282
LED INDICATION OF:
Power supplies on board, analogue input present, analogue reference absent, PAL/NTSC standard, 10 bit decoder in operation
LOCAL CONTROL:
Piano Switch controls automatic/manual selection of 10 or 8 bit decoding (automatic by amount of jitter on input, VHS needs 8 bit decoder). Automatic/manual selection of PAL/NTSC standard. Composite/Y/C input and VBI blanked or unblanked. Variables and options set by shaft encoder with values and prompts on 10 character alphanumeric display on board edge. These variables may also be set remotely. Framestore output timing (0 to 2 fields set as vertical and horizontal offset), gain settings and NTSC setup leve
REMOTE CONTROL:
RS422/485 and RS232. 19200 baud 8 bits, 1 stop no parity. 2 serial ports - 1 connected to frame front panel, 1 is linked to rear of frame. Front panel control from frame active panel and remote panel

DEC103S
As DEC102S with the addition of 'bandsplit' decoder option. This is an additional 10 bit decoding system for PAL composite inputs. With some types of real pictures this produces improvements in picture sharpness, and reduction of comb artefacts. The DEC103S is recommended for broadcast use in PAL systems. The DEC103S loses the 10 bit Y/C input in NTSC use, and so the DEC102S is recommended in NTSC systems. When both standards are used, the DEC103S can be used for improved PAL decoding at the expense of NTSC Y/C input, or the DEC102S can be used if 10 bit NTSC Y/C input is required

DEC101S
This is a reduced cost DEC103S, with only the 8 bit decoder. It converts both composite or Y/C input, but uses the 8 bit decoder for stable as well as unstable sources. This is an ideal decoder to use with VHS or other non-broadcast composite or Y/C sources. All inputs, features and operation modes are the same as DEC102S but with reduced analogue performance. Power consumption: 6.25 watts
