In a television, which can be connected to a portable information terminal, it is possible to display video based on the data of a multimedia file stored on a storage medium even in cases where there is no built-in decoder. In cases where a TV itself does not possess a decoder which can decode the data of a multimedia file selected by the user from the multimedia files stored on the USB memory, the CPU of the TV transmits to a smartphone the data of the selected multimedia file and a decoding request command to request that the data be decoded, thus receiving a video signal and/or an audio signal obtained by various types of decoders of the smartphone. Consequently, the CPU of the TV can output video and/or audio to a display unit and a speaker on the basis of the data of the selected multimedia file.

A display device includes: a second shared memory which is used for sharing data with a smartphone, and into which an identification information item of a process corresponding to a hardware key included in the smartphone is written from the smartphone; a second identification information receiving unit which receives the identification information item from the smartphone by reading the identification information item from the second shared memory; and a second identification information transmitting unit which transmits information indicating selection of the identification information item to the smartphone, by writing the information in the second shared memory.

When a target image with an aspect ratio of 4:3 is displayed on the screen A of the PDPwith an aspect ratio of 16:9, the rectangular black images on the left and right of the target image are not solid black. Instead, the luminance of the rectangular black images is lowered stepwise as it becomes more distant from the boundary of the target image, and finally reduced to substantially zero, or to a black image at a position away from the boundary to some extent. This prevents the luminance from sharply falling from the boundary and edge from causing due to the addition of the rectangular black image, thereby preventing burning on a part of the screen A corresponding to the position of the boundary.

The present invention discloses an HDTV, and a method for controlling adjustment of the HDTV, which make it possible to set control information of the HDTV easily at low cost without unpacking the TV set. Adjustment data is included in an INFO frame, transmitted from an external device, and written into a register of an HDMI receiverthrough a video signal input terminal. Further, a microcomputerreads the adjustment data and controls the adjustment of the HDTVbased on contents of the data.

When showing a picture without trimming it while a video signal stored in a frame memoryhas an aspect ratio different from that of a screen of a plasma display panel, with respect to video signals Eand Ein areas bordering on blank zones Eand Econtaining no picture appearing in upper and lower or right and left ends of the screen of the plasma display panel, a video signal processorreduces a luminance difference by lowering levels of overshootsandand undershootsandaccompanying sharpness processing applied to cope with blurring in edge portions caused by bilinear interpolation, thereby suppresses burn-in of the video signals Eand Ein said areas bordering on the blank zones on the plasma display panel

According to the invention, performing torn curb correction processing by referring to plural correction tablestofor plural display areas A, B, C, D, E, and P makes it possible to obtain an output image meeting user's requirements. Particularly, since tone curve correction processing can be performed by referring to different correction tables selected from the correction tablestofor a main screen to be displayed in the display areas A, B, C, D, and E and for a subscreen to be displayed in a sub-display area P, discomfort to a viewer attributable to a difference in brightness between the main screen and the subscreen can be prevented.
