Support for Media

Connected TV devices are designed to support only specified types of media, including graphics, images, video, fonts, audio, and sound effects. Each device's media player will support a different subset of media types. Check the device specification to determine the supported media types.

Elements for navigation in the user interface are displayed in the graphical plane, while video and fullscreen images are displayed by the video plane. Media contents in the video plane are controlled by the device's media player.

Graphics

Graphics optimized for the connected TV environment can be displayed in the graphical plane. Thumbnail images or images used for navigational purposes can also be displayed in the graphical plane.

Images

While fullscreen images and slideshows can be displayed in the graphical plane, it is recommended that they be displayed in the video plane.

Video

Video can come from a number of sources, these include: the local home network, local persistent storage on the device (flash or hard drives), temporary storage on the device (removable USB drives), and the Internet. Videos can consist of either individual web clips or web channels (for example, dynamic playlists of web clips). Videos should always be displayed in the video plane.

Fonts

Fonts are displayed in the graphical plane. A default font optimized for television is included in the Platform. This default font is used by the Platform and by all apps. The following default font properties are fixed and not customizable by device partners:

  • Font type:        Helvetica Neue

  • Default color:   #FFFFFF (White)

Variations for the default font include bold, bold italic, regular, italic, light, and light italic. The default font can also use a shadow or glow to improve readability against some backgrounds. The supported fonts include:

  • Helvetica Neue
  • Helvetica Neue Bold
  • Helvetica Neue Bold Italic
  • Helvetica Neue Condensed
  • Helvetica Neue Condensed Bold
  • Helvetica Neue Italic
  • Helvetica Neue Light
  • Helvetica Neue Light Italic

Audio

The main audio for a connected TV device comes from media playing in the media player or from an HDMI pass-through (if supported by the device). Audio is sent over HDMI or S/PDIF. Volume and mute are controlled directly on the television or AV receiver. Audio is played by the same media player used to play video. Each device supports only a subset of specified media types. Check the device specification to determine the supported media types.

Sound Effects

Sound effects, if supported by the device, can enhance the connected TV experience. Sound effects are mixed with the main audio from the video plane. However, this capability is not sufficient for playing music or long-form audio streams. Sound effects are tied to the graphical plane and are not controlled by the device's media player.
