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: Provided are an apparatus and method for stably correcting handshake that occurs during a camera panning situation. In the method, movement information is accumulated by a predetermined unit for a predetermined period of time. A regression model is matched to the accumulated movement information so as to determine a situation as one of a panning mode and a handshake mode. Switching is performed between the handshake mode and the panning mode according to the size of a matching factor generated by the matched regression model. Handshake is corrected on the basis of a handshake correcting amount determined according to one of the handshake mode and the panning mode.
