Media Player

Traditionally, a TV is a device for watching media. Many Smart TV applications provide videos, images, and music. This chapter provides 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, and so on)
• Playing status display area (progress bar, play time, play speed, and so on)
• Control buttons

Figure 1 provides an example of playing a video. A banner including more information about the media, the current playing status, and control buttons overlaps the video at the top. The banner disappears when the controls are not used for a certain period. The banner reappears when there is any further input.

Controlling Video Playback with the Smart Remote

Only one physical button on the Smart Remote, the PLAY/PAUSE button (), can directly control media 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 1 illustrates the basic on-screen playback controls.

Function	Button	Action
Play Pause	Play | Pause	Toggle between Play and Pause
Scan or Skip		Rewind	Skip back 10 seconds
		Fast-Forward	Skip forward 10 seconds
Move	Normal | Dimmed	Play the previous video (Dimmed when no video is available)
	Normal | Dimmed	Play the next video (Dimmed when no video is available)

Table 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 buttons work 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.

Table 2 illustrates the basic playback controls on a standard remote control.

Function	Button	Action
Play		Play
Pause		Pause
Scan or Skip		Rewind	Skip back 10 seconds
		Fast-Forward	Skip forward 10 seconds
Move		Play the previous video (No response when no video is available)
		Play the next video (No response when no video is available)

When any physical button is pressed, the on-screen playback controls appear and the control button that corresponds to the pressed button is focused on.

Viewing Pictures

The screen for viewing pictures may contain the following components:

• Area for displaying pictures (full screen)
• Related information (title, date, keyword, and so on)
• Buttons such as zoom-in/zoom-out, rotate, previous/next picture, slideshow, and so on

Figure 6 shows an example of viewing pictures.

Playing Music

The screen for playing music may contain the following components:

• Playing music
• Related information (title, creator, keyword, and so on)
• Playing status display area (progress bar, play time, play speed, and so on)
• Control buttons
• Playlist

Figure 7 is an example of playing music.
