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.
The screen for playing videos may contain the following components:
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.
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.

The PLAY/PAUSE button works differently depending on the current playback status.
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.
The standard remote control provides various physical buttons to control playback.
Table 6-2 illustrates the basic playback controls on a standard remote control.
