1. Introduction
SM01 is a video encoder and pattern generator supporting standard
definition video standards.
As a video pattern generator, SM01 can generate 15 NTSC, 15 PAL and 15
960H line based patterns, a zone plate generator, and a programmable
12MHz maximum horizontal frequency sweep. These are output as
simultaneous SDI (SMPTE-259M
– NTSC/PAL only), YPbPr component,
NTSC-M/J/443 or PAL-M/60 (for 525 line standards) or PAL-BG/I or PAL-N
(for 625 line standards) or 960H (NTSC or PAL) or 1280H (NTSC or PAL
–
zone plate, vertical and horizontal sweep only) formats.
Patterns available include:
75%/100%/SMPTE/Bars+Red colour bars
Black/White/50% grey flat fields
2T, 20T and Pulse bar
CCIR17/18/330 and 331
FCC Comp and FCC MB
N7C MBF and N7C MPF
Ramp
Multi-burst
Horizontal (up to 12MHz) and Vertical Sweeps
5/10 step linearity
Pathological (SDI test)
Gamut
Bowtie
Circular Zone Plate
In addition programmable amplitude noise may be added to the CVBS
pattern output. Noise can be 50Hz or 60Hz hum and/or white noise.
As a video encoder SM01 accepts 525 or 625 line SMPTE-259M inputs
which it encodes to
simultaneous SDI (SMPTE-259M), YPbPr component
and NTSC-M/J/443, PAL-M/PAL-60 (525 line standards) or PAL-BG/I, PAL-
N (for 625 line standards). Again noise may be added to the CVBS output.
