Claim:
A digital cable television (TV) receiver, comprising: a Point of Deployment (POD) module; and a host device comprising a controller and a plurality of digital visual interface (DVI) ports linked to a plurality of peripheral devices, respectively, wherein the controller generates DVI status information associated with the plurality of the DVI ports in response to a single diagnostic request and transmits the DVI status information to the POD module through a central processing unit (CPU) interface in response to the single diagnostic request for a DVI status, when the single diagnostic request is received from the POD module through the CPU interface, wherein the CPU interface enables the DVI status information to be transferred between a CPU of the host device and a CPU of POD module, and wherein the DVI status information includes a connection status indicating whether or not a connection exists on each of the DVI ports, and the DVI status information is generated in such a manner that DVI status information for the plurality of the DVI ports is collected by repetitive diagnostics.
