VGA / HDTV Video Processor

1. Introduction

1.1 General

SC-VGA-2 is a highperformance universal VGA / HDTV to VGA / HDTV Scan Rate converter. It also offers the capability to "Mirror" the VGA input signal on the Xaxis.

The Video Processor combines the functions of a video scaler, scan-converter, and format transformer and is packed into a compact and durable metal housing with easy-to-use touch buttons. The SC-VGA-2 is controlled via push button and OSD menu.

The controls include input/output setup picture adjustment, H/V phase adjustment, System information and many other advance options.

The SC-VGA-2 allows you to specify a resolution and refresh rate for it's output. Then it will output a steady (uninterrupted) VGA signal to your display device at your specified rate regardless of the input. This effectively allows any VGA switch, such as HRT's VS-2 or VS-4, to become a seamless switch. The output timing is constant regardless of what is happening at the input. So when you switch from one input to another, the display device does not see any interruption in the signal coming to it.

1.2 Features

• The resolution of any PC or HDTV video signal can be scaled up or

scaled down to any other PC or HDTV resolution. It can also change the frame rate of the output.

• Large Video memory for real-time frame rate capture & conversion.

• Signal format conversion between RGBHV and YPbPr.

• Input: PC(VGA/SVGA/XGA/SXGA) + HDTV(480i 576i 480p

567p 720p 1080i), @ 60 to 85 Hz

• Output: PC(VGA/SVGA/XGA/SXGA) + HDTV(480p/576p/720p)

Model SC-VGA-2

• Automatically detects input mode and timing parameters

• Allows fine-tuning the output picture to optimum through

adjustment of sampling clock, phase, and position on screen.

• Easy- to- use push buttons and OSD menu control.

• Can Mirror VGA output Horizontally; perfect for teleprompting and

rear projection systems

2. Installation

2.1 Input connection:

The SC-VGA-2 can accept both PC and HDTV inputs. When accepting a PC input use the 15-pin D-sub cable to connect the output of a PC device to the input connector labeled PC/HDTV on the back of SCVGA-2.

When accepting a HDTV input use a15-pin D-sub to YPbPr/3 RCA cable to connect the YPbPr/output (or YCbCr) of a HDTV device to the PC/HDTV input connector of the SC-VGA-2.

The SC-VGA-2 can automatically detect the mode and resolution of the PC/HDTV input.

2.2 Output connection:

The SC-VGA-2 can output a variety of PC resolution and HDTV progressive resolution.

When one of the PC resolutions is selected as output, use the 15-pin DSub VGA cable to connect the PC/HDTV output of the SC-VGA-2 to the VGA input of a display monitor.

When one of the HDTV resolutions is selected as output. use a 15-pin D-Sub to YPbPr/3 RCA adaptor cable to connect the PC/HDTV output of the SC-VGA-2 to the YPbPr input of a HDTV device.

________ Note _______

If you need a 2nd un-altered version of the input Video, please use a Model 200 Video Splitter at your video source. For example when the SC-VGA-2 is set to mirror the video, you can have a mirrored and a non-mirrored output.
