An image display device capable of being incorporated into a projector, an HMD, or the like and capable of adjusting an image formation position for each image area, a projector, and a transmission type display device into which the image display device is incorporated. In an image display device, a refractive index distribution regarding a passing area of light emitted from an optical modulation device is changed by a pixel unit of a refractive index distribution variable panel. In a projector in which the image display device is incorporated, the refractive index distribution variable panel is inserted immediately after the optical modulation device so as to make it possible to perform focusing at all areas even for a screen (surface to be irradiated) having any shape.

An antenna system for receiving over-the-air broadcast television signals includes a steerable directional antenna, a pedestal on which the directional antenna is rotatably mounted, a stepper motor to effect rotation of the steerable directional antenna, and a control circuit. The control circuit receives a control signal and causes the stepper motor to effect rotation of the steerable directional antenna. The directional antenna is steered such that its main lobe is generally directed to a television signal transmitting antenna selected by the user of the antenna system. The steering of the directional antenna is based on geographic location information associated with the television signal transmitting antenna.

To enhance positional accuracy of a speaker unit and to prevent sound leakage of sound outputted from the speaker unit and air leakage. Included are: a display configured to allow an image to be displayed on a display screen; a front board mounted on a front side of the display; a mount frame that is mounted on a rear surface side of the front board and includes a speaker mount section; a speaker bracket that is mounted on the speaker mount section and includes a sound output hole; and a speaker unit that is attached to the speaker bracket and includes a sound output section. The speaker mount section is provided with an insertion hole. The front board is provided with a mount hole superposed on the insertion hole. The speaker bracket is provided with a mount protrusion that is inserted in the insertion hole and the mount hole and is positioned with respect to the mount hole. The speaker bracket is provided with a sealing cushion located around the sound output section.

A display control apparatus includes a display control section that generates a virtual space image by specifying a viewpoint position and a direction of line of sight and displays the image on a head-mounted display. The display control section can specify a plurality of positions in the virtual space as viewpoint positions and can change the viewpoint position to a position determined from among the plurality of positions in accordance with an attitude of the head-mounted display, and when the viewpoint position is changed, the display control section specifies, as a direction of line of sight, the direction in which a first position in the virtual space is seen from the changed viewpoint position.

A display device comprised by being provided with: an image source for emitting image light; a lens for enlarging the image light and emitting the image light to the viewer side; and an optical sheet disposed between the image source and the lens or on the viewer side of the lens, wherein the optical sheet comprises at least two or more layers, a plurality of convex shapes are formed at interfaces between the layers, a difference n in refractive index between the layers adjacent to each other satisfies 0.005n0.1, a half-value angle of the optical sheet satisfies 0.050.2, and a diffusion angle of the optical sheet at which a maximum brightness becomes 1/20 satisfies 5.

A case for a display apparatus and the display apparatus including the same are discussed, which are beneficial in terms of publication of components and diversification of design. The case includes a guide protrusion at a corner portion of the guide panel, and the case top includes a guide groove in which the guide protrusion is located. If a guide panel body portion and a guide panel corner portion are separated from each other and are coupled to each other in an interference fit manner, such that the guide panel body portion is commonly used for public purposes and constituent components of the guide panel corner portion are changed, the case for the display apparatus properly copes with various display devices having different configurations.

A portable media content device for providing media content to remote devices external to a home network, the portable media content device may include a processor in communication with a memory configured to maintain media content, and a transceiver. The processor may be configured to recognize a home network provided at a first location, instruct the transceiver to transmit a media request to an in-home media recorder connected to the home network and at the first location, receive, in response to the media request, media content from the media recorder and to store the media content in the memory.
