Abstract:
An image forming apparatus includes a storage unit to store correlation information between a type of error that occurs in the image forming apparatus and user information, an error detection unit to detect an error of the image forming apparatus, a search unit to search for user information corresponding to the detected type of error according to the correlation information, and a notification unit to notify an occurrence of the error using the searched user information.
Abstract:
A data transmitting/receiving apparatus and method in which color gamut information is added to a teletext signal in a blanking interval so that a display device can recognize whether a color gamut has been extended, are provided. The apparatus includes a control unit which determines whether an image signal is a wide color gamut signal. A signal processing unit encodes color gamut information of the wide color gamut signal and allocates the color gamut information to a data region of a teletext interval if it is determined that the image signal is the wide color gamut signal. The signal processing unit transmits an image signal including a teletext packet in which the color gamut information is recorded.
Abstract:
