Traditionally, a TV is a device for watching media. Many Smart TV applications provide videos, images, and music. This chapter will provide examples of basic screen layouts for convenient media players that are suitable for use on the TV.
Playing Video
The screen for playing videos may contain the following components:
Playing video
Related information (Title, summary, creator, keyword, etc.)
Playing status display area (Progress Bar, Play Time, Play Speed, etc.)
Control buttons
Figure 6-1 is an example of playing video. A banner including more information about the media, the current playing status, and control buttons will overlap at the top. The banner disappears when the controls are not used for a certain period. It will reappear when there is any further input.
Controlling Video Playback with the Smart Remote
Only one physical button, the PLAY/PAUSE button (), can directly control the playback.
For this reason, any video player application must provide on-screen playback controls so that the users can control the playback as with a traditional remote control. The on-screen playback controls must be accessible with the SELECT and 4 navigation buttons or by using the pointing interactions with the Smart Remote.
Table 6-1 illustrates the basic on-screen playback controls.

Table 6-1. Basic on-screen playback controls
The PLAY/PAUSE button works differently depending on the current playback status.
When a video is playing, pressing the PLAY/PAUSE button pauses the video.
When a video is paused, pressing the PLAY/PAUSE button resumes the video.
When either action is performed, the on-screen playback controls appear and the PLAY/PAUSE button is focused on.
The LEFT, RIGHT, and SELECT button works differently depending on the availability of the on-screen playback controls.
When the playback controls appear on the screen, pressing the LEFT or RIGHT button selects a different item and pressing the SELECT button confirms the selection.
When there are no playback controls on the screen, pressing the LEFT or RIGHT button skips back or forward 10 seconds. When either button is pressed, the on-screen playback controls simultaneously appear and the progress bar is focused on.
When there are no playback controls on the screen, pressing the SELECT or UP or DOWN button displays the on-screen playback controls. At this time, the PLAY/PAUSE button is focused on.
The on-screen playback controls disappear 5 seconds after users stop interacting with them.
Controlling Video Playback with standard remote control
The standard remote control provides various physical buttons to control playback.
