Abstract: A server of a content output system acquires a user parameter registration information including a user name of a display and a title of a request content. When an image-quality and sound-quality optimum parameter is included, the server acquires the image-quality and sound-quality optimum parameter as a user's user setting information. When the server cannot acquire the user's user setting information, the server retrieves a user parameter registration information including a user name of another person and the title of the request content.

Abstract: There is provided an image signal processing device including: a compositing unit that masks a peripheral portion of an image by superimposing a mask signal on an image signal in under-scan where an entire image signal is set to and displayed on a matrix display.

Abstract: The present invention intends to provide a display position control apparatus which can prevent a position control signal to control a display position of an image from being unstable and can display the image with high image quality. A delay signal having a phase difference in a match state with reference to a vertical sync signal is generated. Whether a phase relation between the vertical sync signal and a horizontal sync signal is in a mismatch state is detected. When it is detected that the phase relation is in the mismatch state, a display position control signal is generated on the basis of the vertical sync signal and the delay signal. When it is not detected that the phase relation is in the mismatch state, the display position control signal is generated on the basis of the vertical sync signal and the horizontal sync signal.
