ABSTRACT:
A digital cable TV receiver includes a POD module and a host device. The host device includes a controller and a HDMI port linked to a first peripheral device. When the controller receives a diagnostic request for HDMI status from the POD module, it generates a HDMI status report and transmits the DVI status report to the POD module. The HDMI status report includes HDMI status information associated with the first peripheral device. If the host device further includes a DVI port linked to a second peripheral device and receives a diagnostic request for HDMI/DVI status from the PDO module, it generates a HDMI/DVI status report and transmits the HDMI/DVI status report to the POD module. The HDMI/DVI status report includes HDMI status information associated with the first peripheral device and DVI status information associated with the second peripheral device.
