Customer Case Study 5

"Could you send us some high resolution images of the text overlay examples in your datasheet
We are considering developing a menu-based system using your text overlay core.
Thank you for your help"

- Customer based in Penang, MALAYSIA

This customer was interested in developing an interactive menu-based system for a Digital-TV application. Their project schedule demanded a quick solution that was easy to implement and small enough to fit in to a low-cost FPGA. We sent them some example images for them to look at.

Using a series of three text-overlay cores in series, we demonstrated a simple menu-based system inserted over an RGB video source. The first text-overlay core generated the basic menu structure. The second overlay generated the menu title bar and the last overlay inserted a series of lines to delineate the menu entries. With additional alpha-blending support the menu could be faded-in and faded-out of the display area.

The end result was a simple but effective text-based menu with the option to highlight the various entries. Our customer was happy with the results and went on to develop a more comprehensive multi-level menu-based system.

Conclusion

Our text overlay core is ideal for interactive menus, lists and tables. What's more, it is totally versatile with fully customizable character sets and a simple programming interface. Many text overlay cores may be connected in series to add extra colours and detail for a more professional result.
