The following components can be included when creating a screen layout for playing videos or music.
- Playback screen (Original size or full screen)
- Information related to playback content (synopsis, writer, keyword, etc.)
- Playback status display area (Title, progress bar, playback duration, playback speed, etc.)
- Key Guide area for playback controls
Figure 7-1 is an example of a screen layout that shows a video in its original size in the playback area and information related to the content, such as a synopsis and keywords. In the playback area, the content title, playback status (playing, paused), progress bar, and playback duration are displayed.

Figure 7-2 is an example of full screen playback. The content title and playback status (playing, paused), progress bar, and playback duration are displayed at the top and a Key Guide for playback controls is displayed at the bottom. The information banners at the top and bottom of the screen disappear if there is no button input by the user for 5 seconds, and reappear upon button input.
If the service provides sound, the volume OSD of the TV is displayed when the volume is adjusted using the volume button on the remote control.

The basic information (title, resolution, created date) and slideshow playback status are displayed at the top of the screen and the Key Guide for playback control is displayed at the bottom of the screen. The information banners at the top and bottom of the screen disappear if there is no button input by the user for 5 seconds, and reappear upon button inputs.
