An intelligent television system provides an operating system and an application framework for controlling a user interface to handle user input events from a handheld remote control. The remote control includes color keys that are configured for triggering different functions in different application panels displayed on the television.

An audio-visual system may include a housing comprising an open upper end and a storage space, an audio-visual device installed inside the housing and exposable through the open upper end, and a lifting device configured to expose or store the audio-visual device inside the housing through the open upper end. The audio-visual device may include a display, a speaker, and a processor configured to control the audio-visual system to operate in a first mode for outputting media art content while the display is stored in the housing according to a first event, operate in a second mode for outputting audio content through the speaker while part of the display is exposed through the open upper end according to a second event, and operate in a third mode for outputting a visual content while the entire display is exposed through the open upper end according to a third event.

According to an aspect, an apparatus may include a media streaming device including electronic circuitry configured to receive media content wirelessly from a media content source, and an audio output cord segment having a first end portion configured to be coupled to an audio input port of the media streaming device, and a second end portion configured to be coupled to an audio rendering device, where the electronic circuitry is further configured to transmit audio content through the audio output cord segment to the audio rendering device.

The present disclosure provides a glass panel of a display screen, of which each side bulges outwards gradually with respect to a connection line of opposing ends of the side, with a vertical distance from a point on the side between an end and a midpoint of the side to the connection line of the opposing ends of the side increasing gradually in a direction from the end to the midpoint.

A sound output apparatus includes a display panel for displaying video content; one or more first sound output driving units for vibrating the display panel on the basis of a first sound signal which is a sound signal of the video content displayed on the display panel and for executing sound reproduction; a plurality of second sound output driving units for vibrating the display panel on the basis of a second sound signal different from the first sound signal and for executing the sound reproduction; and a localization processing unit for setting a constant location of a sound output by the plurality of second sound output driving units by signal processing of the second sound signal.

In a head-mounted display 100, an input information acquisition unit 140 receives selection of content by a user. A frame rate information acquisition unit 144 acquires information relating to a frame rate of the content, and a luminance adjustment unit 146 determines display luminance according to the frame rate. A content reproduction unit 142 reproduces an image of the content, and a display unit 150 displays the image at the determined luminance.

A display apparatus includes a light guide element, and an incident optical system causing light coming from a display element to enter the light guide element that includes a first light guide part guiding the light coming from the incident optical system in a first direction and a second light guide part guiding the light coming from the first light guide part in a second direction intersecting with the first direction. The first light guide part has mirrors disposed along the first direction and guiding the light to the second light guide part by reflecting the light. The mirrors include a first mirror and a second mirror, each having a first reflection region and a second reflection region having a higher reflectance than the first reflection region. Light having transmitted through the first reflection region of the first mirror enters the second reflection region of the second mirror.

A virtual image display device includes a projection optical system that projects an image display light toward a virtual image presentation plate. The projection optical system includes a first concave mirror that reflects the image display light toward the virtual image presentation plate and a second concave mirror that reflects the image display light toward the first concave mirror. Defining a reference plane along both a direction of incidence and a direction of output of the image display light on the virtual image presentation, the first concave mirror is oriented such that the image display light is incident on the first concave mirror in a direction along the reference plane, and the second concave mirror is oriented such that the image display light is incident on the second concave mirror in a direction intersecting the reference plane.
