roVideoMode

This class allows you to set the output video resolution. The same video resolution is applied to all video

outputs on BrightSign. Video or images that are subsequently decoded and displayed will be scaled (using

the hardware scalar) to this output resolution if necessary.

Interfaces:

• ifVideoMode

rotBOOL SetMode(rotSTRING mode)

• ifSetMessagePort

rotVOID SetPort(rotOBJECT obj)

Supported modes that can be passed to SetMode on the HD600 are:

• "ntsc"

• "pal"

• "640x480x60p"

• "800x600x60p"

• "1024x768x60p"

• "720x480x60p"

• "1280x720x60p"

Supported modes that can be passed to SetMode on the HD2000 are:

• "1024x768x60p"

• "720x480x60p"

• “720x576x50p”

• "1280x720x60p"

• “1280x720x50p”

• “1920x1080x60i”

Note that the BrightSign Hardware has a video anti-aliasing low pass filter that is set automatically. See

the hardware manual for more information.

On the HD2000, if the video mode specified in SetMode is different than the object’s current video mode,

the unit will reboot and set the unit’s video mode to the new setting during system initialization.

Example:

This script prints out video mode resolutions as the user presses the front panel button (note that the video

selector front panel button is not currently implemented on the HD2000):

v=CreateObject("roVideoMode")

v.SetMode(“1024x768x60p”)

p=CreateObject("roMessagePort")

v.SetPort(p)

loop:

msg=wait(0,p)

print msg.GetWidth()

print msg.Height()

goto loop
