Genlock

Genlock is used to minimize video delay, for 480i/1080i to 24Hz conversion, and to avoid an occasional dropped or

repeated frame. It can slow down source and mode changes, so Lumagen recommends setting Genlock to ‘off’ for

cable and satellite set top boxes. The command is:

MENU Input Video Setup [Resolution] Control Genlock (Auto, Disabled)

Game Mode

To minimize video processing latency, when playing video games, turn “Game Mode” on.

Interlaced sources

480i/576i/1080i are treated as 240p/288p/540p. Deinterlacing, and Enhance settings are not available.

Typically

game mode is enabled for a specific input memory that is then selected while playing games. For games that have

a vertical rate that matches the Radiance output vertical rate, turning “Genlock” on can further minimize video

latency. Game mode is not intended for video/film program material, such as television shows.
The command is:

MENU Input Video Setup [Resolution] Control Game Mode (On, Off)

Reinterlace

Converts 480p and 576p sources back to interlaced so the Radiance can do the deinterlacing. This can provide

dramatic improvements to a picture that has been poorly deinterlaced prior to coming into the Radiance.

Reinterlacing also allows for taking in 480p/576p movies and going out at 24/48/72Hz. With this command you can

"allow" or "disallow" quick remote key control for a particular resolution as well as turn it on/off. If "Reinterlace <>

Keys" are set to ‘allow’ the left/right arrow buttons on the remote can then be used to control reinterlacing. The

left arrow toggles reinterlacing on/off and the right arrow toggles the field order. Depending on how the picture

was deinterlaced, the field order may or may not be important but it can be quickly toggled to see if there is any

difference.

The command is:

MENU Input Video Setup [Resolution] Control Reinterlace

Input Enhancement Controls

Sharpness

This command is used to adjust the sharpness for all inputs. There are controls for horizontal, vertical and diagonal

sharpness (edges) and texture (fine detail). It is generally best to leave these controls at the default setting of 0

or to use moderate settings. Using higher settings can introduce image artifacts. Some people prefer having all 6

settings set the same. Other people prefer only using the diagonal parameters. The command is:

MENU Input Video Setup [Resolution] Enhance Sharpness OK

Noise Reduction

Mosquito noise and block artifact noise are both seen in compressed material. The Radiance has both temporal

and special noise reduction to help reduce the noise level these artifacts introduce into the image. Block artifact

reduction is also supported and can be useful with overly compressed video. The command is:

MENU Input Video Setup [Resolution] Enhance Noise Red. OK

Adaptive Contrast

Adaptive Contrast varies the contrast based on the average level of the central 60% of the picture. When you

adjust the contrast the effect is shown in a centered window for evaluation. The command format is:

MENU Input Video Setup [Resolution] Enhance AdapContrast OK

Copy Enhancement Settings

You can copy the local enhancement settings to other resolutions and memories. The command is:
MENU Input Video Setup [Resolution] Enhance Copy OK
