4.7 OSD

The On Screen Display (OSD) function is to superimpose an image on a screen picture.

The OSD engine can define characters or pictures overlaid with video streaming.

There are two OSD engines can be used in the AL360. One is basic 8-color OSD engine

and the other one is 256-color OSD. They are responsible for their respective mandates.

Note- These two OSD engines can

’t be output with SD TV Encoder path, and the 256-

color OSD engine only operates with 148.5MHz internal clock frequency.
