Cisco TelePresence System Codec C90 문제 해결 매뉴얼

Some parts of images are off the edge of

the screen (C Series and SX20)

Overscan means that on some parts of the image, menus and soft buttons may be off the edge of the

screen. The recommended fix for this is to go into the menus of the monitor and turn off overscan if

possible. This may be called 'just scan,' '1:1 pixel mapping', 'dot by dot' or something else as name

varies depending on the manufacturer.

if you cannot fix this using the menus on the actual monitor you can use the settings on the web inter-

face. Go to

Configuration -> System Configuration -> Video -> Output

for the interface being used.

Screen does not turn off in standby (HDMI - CEC)

By default the codecs will stop sending any signal when stand-by mode is activated. For some screens

this is fine, they will register they have no signal and after a brief wait they too go into standby mode.

Some screens however will remain on. For HDMi connections you can enable CEC (Consumer Electronics

Control). Depending on the monitor you are using this can also be called something else: Sony: Bravialink,

lG: Simplink, Sharp: Aquos link, pioneer: Kuro link, philips: Easylink, and Samsung: Anynet+.

To do this go to

Configuration -> System Configuration -> Video

see the HDMi interfaces available. You should check that CEC is enabled on your display screens input

as well from the screens menus.

NOTE

With some screen manufacturers we find their CEC implementation are non-standard and therefore

even with this setting on the screen will not turn off. lG screens are known to use non-standard CEC

and will not accept our standby signals. DVi connections use a difference signaling method thus screens

connected by the DVi output on the codec to the DVi input on the screen should not have this problem.

Video layout customization

You can create new video layouts on the C60 and C90 codecs and change when to display the

existing layouts on the C40. The easiest method to accomplish this is by using the TC Console tool.

please ensure you have the latest version of TC console by visiting

telepresence-developer/home

The Video Compositor allows you to modify the default video compositing behavior of the codec without

the need for any programming. You can add new layouts, change the automatically selected layouts

and control what will be shown to the user depending on the state of the codec.

New to TC6 is that the custom video layouts will be shown on the Touch interface.

Tip

To see the affects of layout changes live on screen you can enable live layouts. To do this navigate

Configure –> Live Layouts

and enable this option.

Settings are not saved onto the codec until the

is then created on the system with the custom layouts and these Api commands are executed upon

startup of the video system.

To see the Api commands for a specific video layout click on the
