Abstract: An information processing apparatus, an information processing apparatus system and a control method of an information processing apparatus are provided. The information processing apparatus includes a network unit which receives user recognition information having time data from an external device; and a processor which outputs a user recognition signal corresponding to the time data if a current time reaches a time corresponding to the time data.

Abstract: A display apparatus includes a display; a communication part which receives an image signal and information corresponding to a first image to be displayed on an external display apparatus and transmits a control signal to adjust the first image; an image processing part which performs image processing to display an image on the display; and a controller which controls the image processing part and the communication part to display the information corresponding to the first image on the display and to transmit the control signal to adjust the first image.

Abstract: In a broadcasting signal output apparatus and a method, an OSD processing unit produces a display-lock message if a display of contents is not permitted. A control unit determines whether the decoded video signal includes a copy protection signal for preventing the video signal from being reproduced, and if so, the control unit requests and receives a certification signal from the display device to determine whether the video signal can be transmitted to the display device through the video output terminal. The control unit then determines whether the certification signal corresponds with the reproduction preventing signal, and if it does not, prevents the decoded video and audio signal from being outputted, and controls the OSD processing unit so that the display-lock message is output to the display device (e.g., screen), so that the user knows when the currently received broadcasting signal is not displayed due to copy protection signal.
