To further enhance the viewing experience of the audience – more precise commands are added to minimize the disruption during a source change.

Furthermore, to avoid confusion with old RS232 commands and possible software maintenance problem the silent OSD are implemented using new RS232 commands. The side benefit of this implementation is user choose silent OSD or non-silent OSD just by invoking different RS232 commands
