Abstract

An open cable set-top box diagnosing system in which a point of deployment (POD), separated from a main circuit unit, having a newly defined interface is used to check an operation state of an open cable set-top box, transmits the checked state to a predetermined server, according to which the operation state of the open cable set-top box is diagnosed. The open cable set-top box diagnosing system includes an open cable set-top box for checking its own operation state by using a diagnosis resource by a communication protocol between a point of deployment (POD) separated from the main circuit unit and the main circuit, and a head end for providing a service corresponding to a request signal received from the open cable set-top box or providing a broadcast program to the open cable set-top box, and checking the operation state of the open cable set-top box.

Claims5

Dependent claims

A method of interfacing with a point of deployment (POD) module for a host device, the method comprising:

receiving a diagnostic request object from the POD module in accordance with a diagnostic resource, performing a specific set of diagnostic functions according to the diagnostic request and acquiring a diagnostic result from one of the performed diagnostic functions;
and
transmitting a diagnostic confirmation object including the diagnostic result to the POD module in accordance with the diagnostic resource,
wherein the diagnostic result includes a manufacturer name of the host device,
wherein the diagnostic resource defines the diagnostic request object and the diagnostic confirmation object,
wherein the diagnostic request object includes a plurality of identifiers, each identifier being assigned to one of plural functional units in the host device to be checked for a corresponding diagnostic status, and
wherein the diagnostic confirmation object includes state information about each of the functional units.
