Lynx3DM uses the Video Processor block to display the captured data on the LCD, TV, or CRT
display. The captured data can be displayed through Video Window I or Video Window II. The
stretching, color interpolation, YUV-to-RGB conversion, and color key functions are performed in
the Video Processor. Lynx3DM's Video Processor can simultaneously process captured video data
and perform CD-ROM playback on two independent video windows.
Lynx3DM also supports real-time video capture to the hard drive or system memory through PCI
master mode or slave mode. In PCI bus master mode, Lynx3DM uses the Drawing Engine's Host
BLT and Host DMA functions to maximize performance.
1.4.11 TV
Encoder
The TV Encoder is an NTSC/PAL Composite Video/S-video Encoder. It receives RGB inputs and
converts to digital video signals based on CCIR 624 format.
The input video signal of the TV Encoder is RGB 8-bit each. The sampling rate is corresponding to
CCIR 601, Square pixel and 4Fsc (NTSC only).
The output video signals of the TV Encoder are Composite video signal and S-video signals of
10-bit each. These output signals are over-sampled by a double frequency clock called CLKX2.
This feature helps to simplify external analog filtering.
The TV Encoder video timing is controlled by vertical sync and the horizontal sync input signals.
The blank signal input is optional. If the blank signal input signal is pulled up, internal blanking
control will be performed.
Macrovision 7.01 and closed captioning functions are included.
Key features are summarized as the following:
NTSC/PAL interlace mode digital video encoder
Composite Video and S-Video digital output
CCIR 601, Square pixel and 4Fsc (NTSC only) resolution RGB input
Slave timing operation
Interlace mode operation
2x over-sampling data output to simplify external analog filtering
Selectable pedestal level OIRE/7.5IRE for NTSC
Macrovision function (version 7.01)
