Video Text Overlay Unit with PC keyboard interface

& On Screen Scrolling Message Function

The RTCKBD-S unit is no longer sold.
Order RTCKBDBOX instead and ask for the RTCKBD-S firmware.

This unit features the ability to construct scrolling video text overlays from text typed on each of the unit's eight available screen pages. Each message can be up to the length of the entire screen full of characters. The text, and the scrolling feature, are stored when the unit is switched off and scrolling will restart when power is restored. The unit uses the standard UK or US keyboard key mapping, see the documentation. There is no facility to change to the keyboard mappings of other countries.

The RTCKBD-S firmware allows a PC keyboard to be used to create text overlays to annotate a video picture. The RTCKBD-S version does not have a counter interface. Instead it features the ability to create and display scrolling text messages. This is designed for use in ATV repeaters. For full details of the unit's operation please see the details and the documentation.
