1.1. Feature Overview
– Different application modes
• FSM: Frame based high performance master with
PiP
• SSC: Split screen ("Double Window")
• MUP: Multi pictures, several still and 2 live pic-
tures possible
• PC: PC signal in combination with TV signal (TV
in PC or PC in TV)
– Data acquisition connectivity
• Up to seven (VSP 9425B/9427B: nine) CVBS
inputs, up to two Y/C inputs
• Up to three CVBS outputs (even when Y/C input)
• ITU-R 656 compatible digital input
• RGB/FBL or YUV or YUV-H-V input
• 9 bit amplitude resolution for CVBS/Y/C A/D con-
verter
• 8 bit amplitude resolution for RGB/FBL A/D con-
verter
– Multi-standard color decoder with 4H comb-filter
• PAL/NTSC/SECAM including all substandard
• Automatic recognition of chroma standard
• AGC (Automatic Gain Control)
– Second multi-standard color decoder for slave chan-
nel (VSP 94x7B only)
– Processing of two input channels independently:
Master and slave channel
– Temporal noise reduction for master and slave
channel
• Field or frame based temporal noise reduction for
luminance and chrominance
– Pre-scaling of the 1fH signal (master and slave
channel)
• Horizontal scaling factors: 3/2...1...1/28
• Vertical scaling factors: 1...1/30
– Horizontal and vertical scaling of the 2fH signal
(master and slave channel)
• Horizontal Scaling factors: 3...0.75
• 5 zone horizontal panorama generator
– Vertical scaling of the 2fH signal (master channel)
• Vertical scaling factors: 8...0.92
• 5 zone vertical panorama generator
– Detection circuits
• Global motion and global still detection
• Film mode and phase detection (PAL, NTSC; 2-2,
3-2 pull down)
• Measurement of the noise level (blanking)
• Detection of letter box formats
– Embedded memory
• On-chip memory controller
• Embedded DRAM core for field memory
• SRAM for delay lines
– Data format 4:2:2
– Data slicer for closed caption ("V-chip") and WSS
– Flexible clock and synchronization concept
• Horizontal line-locked or free-running mode
