First Claim
1. A method comprising:
- preparing capability information of each of a plurality of devices with regard to signal formats;
designating a device that ultimately receives a signal;
collecting the capability information of every one of the plurality of devices;
producing a plurality of possible transmission paths between the receiving device and other devices, based on the capability information collected;
identifying a device that transmits a signal and a format of the transmitted signal;
selecting one of the plurality of possible transmission paths that matches the transmitting device and the transmitted signal format for a transmission path,issuing commands to the plurality of devices involved in the selected transmission path upon a change of the transmitted signal format; and
controlling input/output of the plurality of devices according to the issued commands to establish the transmission path for issuing commands to the plurality of devices involved in the possible selected transmission paths upon a change in signal format and selecting one of an output of a decoder and an analog terminal.

Abstract
A method including integrating information regarding receiving, transmitting and converting capabilities of each device in a network with regard to signal formats, so that a pertinent transmission path can be determined. Such possible transmission paths can be specified in terms of the order of devices involved in the transmission paths and a signal format between these devices involved. One of the possible transmission paths that match the transmitting device and the transmitted signal format is selected as a pertinent transmission path. The method displays the selected transmission path on a monitor. Commands are issued to devices involved in the pertinent path, and the input/output of these devices is controlled according to the commands to establish the selected transmission path automatically. According to one aspect of the invention, an apparatus includes a means for storing device capability information. Also included is a memory for storing capability information of other devices. An analog input terminal and a digital input/output terminal are included. A decoder coupled to the digital input/output interface is included. A controller to produce possible transmission paths is included. A monitor for displaying a selected path is included to assist a user in manually selecting the path. The controller includes a command generator for issuing commands to devices involved in the possible selected paths. Also, a selector for selecting the path automatically is included.
