ABSTRACT:
A circuit has been shown to illustrate how a vertical indicator can be generated in logic for a simplified OSD generator. The vertical visual indicator generated uses little microcontroller firmware overhead allowing a less powerful microcontroller to be used in the specific application, thus lowering system cost. A single byte is written to a counter to indicate the position of the vertical indicator. The OSD video coming from the OSD logic is overridden with a pixel overwrite signal when the location of the vertical indicator is located. The pixels overwrite whatever is located below the position of the vertical indicator. The pixel overwrite occurs for a predetermined time to fill a predetermined number of pixels. For example, if the vertical indicator is three pixels wide then the pixel overwrite signal occurs until three pixels have been overwritten.
