SDI Setup:

For 3GSDI Level A or B type input modes can be chosen.

SDI audio input is routed to the HDMI and 3GSDI output connector by default.

HQView-5xx can also be set to monitor audio on the SPDIF connector. Audio on the HDMI/3GSDI

connector and SPDIF connector are mutually exclusive.

Two consecutive SDI audio channels can be output on the HDMI/3GSDI output interface. The group can

be chosen. Or all eight SDI audio channels can be transmitted.

Component Setup:

The component interface of the HQView-5xx is configured through this submenu.

The Colour Space can be set to YPbPr or RGB.

The sync signal can be stripped from the Green or Y channel with the setting 3 Wire or from the

separate sync line with the setting 4 Wire.

The Auto setting will automatically detect a sync signal and set-up the HQView-5xx accordingly. This is

setup in under Synchronisation.

Test Pattern:

When the OSD menu is off the test pattern can be toggled through by pressing the up or down keys of

the keypad. For unit control through a web browser or to set up a certain default test pattern please use

the input configuration menu.

Custom test patterns loaded into the file system of the unit through the web interface, can be accessed

through the same means.

Instead of custom test patterns also a screen grab of the current video can be stored in one of the four

slots provided for custom test patterns.

The speed of the moving cross test pattern can be changed. Also, the foreground and background

colour and the line width of the moving cross test pattern can be changed in this menu.

Note: Most test patterns are scaled in multiple unit configurations with Autozoom enabled since they are

useful for setting up the blend and warp of the system. The SMPTE, and Pluge Patterns are not scaled.

Switching Transition:

When switching input channels by default the last frame of the prior displayed image is frozen and

displayed until a stable image of the new input channel can be shown.

The switchover process is supposed to be as seamless as possible. The source and monitor add

switching noise due to unforeseeable activity of the firmware in said devices. By default HQView is in

auto frame rate switching and I/O lock mode. In order to get a best smooth switching result with the

source and monitor I/O lock and auto frame rate switching have to be switched off in the Output/Display

Type menu.

The switching transition of HQView can be set to Freeze, Blank, Fast Fade and Slow Fade.

Freeze halts the prior channel image until the new channel image is stable.

Blank switches the output to show a black screen instead of the last channel image.

Fast and slow fade have the prior channel image faded out and fade into the new channel video image

once it is stable.

3.11.4. Display Mode

The “Display Mode” can be set to either Low Latency or Best Picture.

In Best Picture optimum image processing is applied, whereas in Low Latency mode the lowest latency

is achieved.
