 摘要 :
HD-SDI/SDI to DVI-D and Audio Converter
 描述 :

HDP
HD-SDI/SDI to DVI-D and Audio Converter

The HDP is a miniature HD-SDI/SDI to DVI-D converter for LCD or Plasma monitors. Using a very high quality scaling engine, the HDP will automatically size 4:3 or 16:9 inputs to many DVI-D monitors (see Technical Note below). For appropriate monitor configurations, scaling is automatically 1 to 1 — for example, displaying 1920x1080 video on a WUXGA (1920x1200) monitor. The HDP will also automatically adapt the input frame rate for monitor compatibility. In addition, the HDP provides 2 channel RCA style audio monitoring and 2 looping outputs of the SDI inputs. HDP is the ideal solution for displaying SDI or HD-SDI on any LCD or Plasma DVI-D monitor.
 
 
Technical Note

The HDP is designed to work with most DVI-D monitors. The HDP uses the industry standard EDID communication protocol (within the DVI link) to communicate with the monitor, and then adjusts the HDP's internal scaling engine to scale the input video to the native resolution of the monitor. However, due to the hundreds of variations of DVI formats currently in use, proper operation with all monitors cannot be guaranteed. The HDP has 2 modes of operation that occur automatically, depending on what monitor it is attached to. These modes are Recommended Monitor Mode or VESA Mode.

Recommended Monitor Mode
For recommended monitors, there is custom firmware that will provide an accurate frame-locked image for all supported SDI and HD-SDI input formats. The HDP automatically determines the monitor it is connected to.

Recommended Monitors:

Apple 23" HD Cinema, model M9178LL/A (aluminum bezel)
Sony 23", model SDM-P234
Viewsonic VP231WB (60Hz Vlock native, 50/60Hz Vlock @ 720p)
Dell 2405FPW (50/60Hz Vlock native, 50/60Hz Vlock 720p)
Barco LC-42 (supported on HDP serial numbers H05019 or higher)
Barco LC-47 (supported on HDP serial numbers H05019 or higher)


VESA Mode
For DVI-D monitors not on the recommended list, the HDP will use standard VESA timing based on the particular monitor's "preferred timing" - as determined by the EDID communication with the monitor. Because VESA timing standards are not based on video formats, the HDP cannot frame lock to the input video and will operate like a frame synchronizer — it will frame rate convert by adding or dropping frames as needed. If a particular monitor reports a preferred timing mode that is not supported by the HDP, the HDP will default to standard XGA (1024 x 768 60Hz) timing.

Monitors Tested for Compatibility in VESA Mode:

HP HPL2335 Samsung 170T
Samsung 213T Samsung 243T
Samsung 173P

The HDP is designed for use as a general monitoring device, perfect for use in applications such as:

General post-production reference monitoring
Client monitoring
Presentation
Projection
Corporate displays
Kiosk applications
...And much, much more!
The scaling engine in the HDP makes it a simple and effective way to get full-screen images from a myriad of SD and HD sources. The HDP is not intended as a critical viewing device, for applications such as color-correction, etc. We recommend professional/broadcast grade monitors for such critical applications.
