Abstract
An external source outputs an analog signal containing on-screen information (OSD) for the external source, which has been decoded in the external source, and an encoded high definition digital signal. A high definition television (HDTV) has separate inputs for the analog signal and the high definition digital signal, which is decoded in the HDTV to a format suitable for display on the HDTV monitor. Accordingly, both the OSD information for the external source and the high definition signal are available for use and display on the HDTV monitor.
