VP20
LCD Controller
The VP20 LCD Controller is the ideal LCD controller for applications requiring simultaneous viewing of 2 or more inputs. Three input channels are standard, and 1 additional channel can be supported via input mezzanine boards. Each input can be placed in one or more windows within the output active area.
The VP20 can simultaneously display video from up to 4 input ports: 1, 2, 3) any one of the DVI/RGB/Composite/Component/SOG inputs, and 4) any 1 of a variety of input mezzanine boards.

Video Combining up to WUXGA and 1080P
The VP20 offers robust windowing for display resolutions with pixel clock frequencies up to165 MPixels/s (eg 1080P and WUGA @ 60Hz). Up to 4 windows may be sized and placed anywhere in the output active area. Window techniques include PIP, side-by-side, and more.
Tactical Commands
Tactical commands allow real-time update of a window’s source, that source’s area-of-interest, window size, location, rotation, and color adjustments. These commands are particularly useful for tactical displays requiring dynamic windowing. Tactical commands are defined in the VP20 Command Line Description.
Video Output Interfaces
- Supports most single and dual LVDS panels,
- Supports various LVDS pixel mappings, including multiple MSBit/LSBit arrangements, and 3/4/5 channels (pairs) per link
- Single link TMDS output for up to 1920×1200 displays
- Parallel TTL output up to WUXGA. Compatible with Westar output mezzanines.
Video Conversion and Synchronization
- Digitization of computer-generated analog RGB video sources with separate syncs or sync-on-green, non- interlaced and interlaced
- Digitization and de-interlacing of consumer video formats, including NTSC and PAL Composite, component, and S-Video
- Support for custom video formats and specialty formats such as RS-343, RS-170, and STANAG
- Decoding of DVI (TMDS), DisplayPort, and SDI digital inputs,
- Incoming video gain and offset adjustments, fine phase clock adjustment for RGB pixel sampling, and per window YUV and RGB color space adjustments
- Free-running output or genlocked to an input port
Powerful Configuration Utility
The VP20 is configured via a PC application. VP20 Configure Application supports the setup of:
- Output timing/electrical parameters and synchronization method
- All inputs, including a prioritized list of all applicable video input modes that can be automatically detected for each input port
- Up to 4 windows with mode dependent and mode independent parameters such as size, location, and input area-of-interest for each detected mode per window
- Sequences for display initialization, loss of video, and video detection
All parameters are stored in non-volatile memory for automatic operation upon power up. The VP20 Configure application output is a .cfg file composed of VP20 commands. This file can be downloaded to the VP20 or saved on a PC.
Scaling, Windowing, and Area-of-Interest Control
- Unlimited, independent horizontal and vertical scaling
- Up to 4 windows with programmable size and position
Rotate video, flip left to right or top to bottom
- Image can be reversed left to right and flipped top to bottom
- Image can be rotated 90, 180, or 270 degrees
Optional keying with blending
An optional keying block supports RGB-keyed alpha blend and other techniques between a key plane and the background plane to form the visual plane. Keying is performed on the foreground layer, with programmable foreground and background alpha values for outside the key area, when key=true, and when key=false)
Automatic Video Input Mode Detection
To support multiple input types and resolutions per input port and multiple windows in an embedded application, the VP20 offers a comprehensive approach for automatic detection, conversion, and windowing of multiple video formats. Each input port can have multiple, prioritized video input modes associated with it.
A mode consists of the input type (DVI, VGA, CVBS, etc) and video timing. Each input port has a mode selection subsystem to scan for defined modes per a specific input type and sub-channel (such as VGA1), or sub-channel 1 of multiple input types (Auto mode). Windows are linked to a specific input port. Each window can have either mode-independent or mode-dependent size, location, input area-of-interest, rotation and other parameters.
At power up, each port’s mode selection subsystem initiates a scan. Once a mode is matched (either exactly or within pre-defined limits), that video input is displayed in any associated window(s) per the mode’s window parameters (input area-of-interest, window size, window location, rotation, flip, etc).
