Link electronic HDC-925 Leaflet

INTRODUCTION:

 The HDC-925 1RU product is an up, down and cross conversion unit that promotes image quality

to the Professional video world. The HDC-925 is packed with features such as PixelMotion™ De-interlacing and Multi-

Directional Diagonal filter (MDDF™) algorithms, drastically reducing jaggies on diagonal lines. This product   also

has Per-Pixel Temporal Recursive Noise Reduction algorithm that minimizes HD and SD video noise. 

 

Flexview™ Aspect Ratio is a non-linear anamorphic aspect ratio designed for converting 4:3 aspect ratio material

to 16:9 aspect ratios without the distortion that is often associated with anamorphic stretching. Flexview leaves

the center portion of the image  Untouched and provides increasing amounts of stretch towards the edges of the

image, filling the 16:9 images without distorting the center area of the image. 

This high-quality converter uses the Teranex’s HQV™ Technology and yields unsurpassed image quality for the

demanding user. 

 

This flexible product is able to handle just about all broadcasting formats at its inputs and outputs in either HD

or SD formats. The HDC-925 uses a Silicon Optix Realta image processing engine inside that maximizes image

processing capability. The result? The best possible picture from a flexible, powerful, and user-friendly front

panel. The front panel along with the software allows the user to setup all functions of the HDC-925

OVERVIEW

PixelMotion™ De-interlacing

PixelMotion de-interlacing of video originated material produces perfect progressive

frames in preparation for further processing. The processing aperture is adjusted on a pixel-by-pixel basis, which

preserves all of the detail of the original interlaced image and eliminates jaggies in the output image.

Aspect Ratio Control:

Allows selection from standard aspect ratios, such as common top & bottom, common sides,

14:9 and Anamorphic. In addition, it allows for Flexview, a non-linear anamorphic aspect ratio

, to be used in up-conversions.

Detail Enhancement:

Is an edge-sharpening filter based on a traditional film compositing technique called "Unsharp

Masking." This filter corrects any blurring introduced during image capture, compression or resampling.

Noise Reduction

 Adjustable noise reduction controls offer a greater degree of temporal recursive noise

reduction with fewer artifacts. A bias control allows the aggressiveness to be fine-tuned. For filter performance

testing, a Red Overlay can be applied that will color pixels that are in motion in Red

In situations where the highest image quality up- or down-conversion is necessary, Link’s

HDU-925 uses proprietary PixelMotion™ De-interlacing and Detail Enhancement combined with powerful array

processing to provide the best image solution. 

APPLICATION:

 The first step in the conversion process is to identify whether the input material is video or film

originated. The identification process happens in a fully automatic mode and selects either PixelMotion De-

interlacing for video based material or 3:2 Detection for film based material. The goal is to apply the appropriate

filter in order to recover the full vertical resolution of the input material. 

PixelMotion de-interlacing produces perfect progressive frames in preparation for further processing. The processing

aperture is adjusted on a pixel-by-pixel basis, which preserves all of the detail of the original interlaced image.

Additionally, the filter eliminates “jaggies” in the output image, providing well-defined edges on objects and

producing the sharpest images possible. 

3:2 Detection recognizes the redundant fields inserted by the telecine during the conversion of film to video. This

advanced 3:2 pull-down filter avoids frame rate conversion artifacts and provides the highest vertical resolution

and motion quality. 

Since the quality of the video de-interlacing is so high, there will be no difference visible in the vertical resolution

seen with film originated material and that of the de-interlaced video originated material. 

Once the image has been de-interlaced and up-converted, Detail Enhancement can be applied to the image to

further sharpen and enhance the output. This filter adds an additional level of image quality by helping to better

define the detail in the up-converted image. Detecting the edges of objects and adjusting the contrast ratio around

those objects to help separate them from the Background achieve this.
