  • Patent number: 7634797
    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.

  • Patent number: 7167210
    Abstract: A signal transmission method and apparatus provides a digital transmission path and an analog transmission path between a signal output apparatus and a signal input apparatus. An audio/video signal is transmitted from the signal output apparatus to the signal input apparatus over the digital transmission path. When a user requests an on screen display (OSD) from the signal output apparatus, a controlling unit of the signal output apparatus judges a volume of the data to be displayed via the OSD. If the volume exceeds a preset limit, the OSD is transmitted to the signal input apparatus over the analog transmission path. If the volume does not exceed the preset limit, the OSD is transmitted to the signal input apparatus over the digital transmission path. The controlling unit of the signal output apparatus informs a controlling unit of the signal input apparatus of the intended path of the OSD, so that the signal input apparatus can process the OSD in the appropriate manner.
