Abstract

A method for managing the connection of a plurality of devices connected by a digital is provided. The method includes operation modes having a normal mode for performing a usual operation specified in the relevant digital interface standard and a private mode for performing an operation selectively controlling the external device, and includes: (a) a user sending a command requesting an operation mode be established in a private mode to a first arbitrary device; (b) the first device establishing the private mode as the operation mode in response to the user's command; (c) the first device identifying devices having the right to access related registers to store in the first device information relating to the identified devices; (d) the first device determining whether there is a request for access to the related registers by a third-party device; (e) determining whether the third-party device is included in the previously stored devices if there is a request; (f) the first device accepting a request of the third-party device if the third-party device is determined to be included in the previously stored devices; and (g) the first device returning an error code to the third-party device, which indicates that the first device cannot accept the request, if the third-party device is not determined to be included in the previously stored devices. Thus, privacy can be ensured in a connection between digital devices.
