9. Media Player

The Media Player on the Braille Sense U2 is a program you can use to play audio files as well as listen to the audio for some video file formats. The Media Player plays the following formats, ac3, asf, asx, m3u, mp2, mp3, MP 4, mpa, mpg, ogg, pls, wav, wax, wma, flac, midi and wmv. Note: you cannot see the video for "avi" and "wmv" files, however, you may listen to the audio contained in these formats.
You can control the playing of audio files using either Braille keyboard commands or the media buttons on the front panel of the Braille Sense U2. The Media Player can play back audio recordings and books as well as music files.

9.1 Using the media buttons

Near the center of the front panel on the Braille Sense U2 is a group of 5 buttons with varying shapes. These buttons can be used to control the Media Player. Moving from left to right, the buttons are: "Back", "Record", "Stop", "Play/Pause", and "Forward". These buttons are used for playing and recording music or voice quickly and easily.
The media buttons can control media playback, DAISY content playback, or FM radio operation, depending on the position of the Media Mode switch, located to the left of the media buttons. Slide this switch to the right-most position, "Media Mode",  to control media playback. 

If the "Play/Pause" button is pressed while you are using another program on the Braille Sense U2, the unit opens the Media Player and begins playing the files in the most recently played  list. If there are no files in the playlist, the Braille Sense U2 says, "There are no items to display". "Back", "Stop", and "Forward" are available after audio playback is started. 
Note: As the Braille Sense U2 is able to multi-task, initiating audio playback with the "Play/Pause" button does not close the program you were running when you pressed it. To return to your former position, press "F2-F3" to cycle through the running programs until you reach your former location. 

9.1.1 Play/Pause Button

The "Play/Pause" button has a long, rectangular shape. It is the second button from the right in the group of media buttons. As explained above, pressing the "Play/Pause" button starts playback of the files in the most recently played media playlist. A playlist can contain only 1 file, or many files. If there is more than one file in the playlist when you press the "Play/Pause" button, the Braille Sense U2 plays all the files in the list one after another. If you press the "Play/Pause" button during playback, audio playback is paused. To resume playing, press the button again. If you press the "Play/Pause" button while you are in the "Record" dialog, the most recently recorded file is played. 

9.1.2 "Forward" button and "Back" button

Both of these buttons have a triangular shape. The "Back" button is the left-most button in the media group and is pointed to the left. The "Forward" button is the right-most button in the media group and is pointed to the right. If you press the "Forward" button, the next file in the playlist is played, and pressing the "Back" button plays the previous file. If you press one of these buttons while an audio file is playing, the Braille Sense U2 stops playing the current file, and jumps to the previous or next file (depending on which button you press) and starts playing it. If you press the "Forward" button (while the last file in the list is playing, (or the "Back" button (while the first file in the list is playing), it has no effect, as there is no file to navigate to.  

9.1.3 Record Button

The "Record" button has a circular shape, and is used to record sound using the built-in or an external microphone. The "Record" button is located directly to the right of the "Back" button. You can use this button to create a recording from anywhere on the unit provided the Media Mode switch is set to the right-most position. Pressing the "Record" button once, opens the "Record" dialog. Press the "Record" button again to start recording. Press the "Record" button while you are recording to pause recording. Resume recording by pressing the "Record" button one more time. Press the "Stop" button, directly to the right of the "Record" button, to stop and save your recording. The recorded file, is saved in the "flashdisk/media/record" folder. 

9.1.4 Stop Button

The "Stop" button has a square shape and a dot on it, and is used to stop playback or recording.   If you press "Stop" during audio playback, the next time media playback is launched, the Braille Sense U2 starts playing the first file in the playlist. If you press this button while recording, the Braille Sense U2 stops and saves the recording. If you press the "Stop" button in the "Record" dialog when not recording, the dialog closes.

9.1.5 Using the media buttons in Open File dialog

Press and hold the "Stop" button to open the "Open File" dialog from within the "Media Playback" dialog. Press and hold "Stop" again to close the "Open File" dialog and return to the "Media Playback" dialog.
In the "Open File" dialog, the "Play/Pause" button functions the same as "Enter". The "Stop" button, "Record" button, "Back" button and "Forward" button function the same as "Backspace", "Space", "Space-1" and "Space-4" respectively.
Namely, you can navigate up and down by pressing the "Back" and "Forward" buttons in a file list; and you can select and unselect items by pressing the "Record" button. Press the "Stop" button to move back a level in the folder structure. And press "Play/Pause" button to play the selected files. 

9.2 Braille Keyboard and Extended Keys

You can use the Braille keyboard to perform the same functions as the media buttons as well as more advanced features in the Media Player. To open the "Media Playback", press "Enter" on "Media Playback", or press m from the Braille Sense U2 "program" menu. As explained previously, you can also open the Media Player by pressing "Play-Pause" when the "Media Mode" switch is set to the right-most position.
The "Media Playback" dialog contains two information tabs: "playback information" and "playlist". Press "Space-4-5" or "Space-1-2" to move between these tabs.

9.2.1 Playback Information Tab

The "playback information" tab displays the track number, the file name, and the current playback status: (play, pause, or stop). If there are no files in the playlist, the Braille Sense U2 displays "Title: There are no items to display". If you press "Space-4", the Braille Sense U2 displays playback time information. 
First, the elapsed or remaining time is displayed. You can set whether the elapsed time or remaining time is displayed, using the "playback settings" dialog. If you have selected the "Remaining time" with this option, the ?(minus sign), is displayed before the time. Next to the elapsed/remaining time, the Braille Sense U2 displays the total playback time of the currently selected file.
If there are no files in the playlist, "Time: There are no items to display" is displayed.

9.2.2 playlist Tab

The "playlist" tab displays all the files in the playlist. For each file in the playlist, it displays the track number, file name, the location of the file in the list, and the total number of files in the list. If there is no file in the playlist, the Braille Sense U2 displays the message "no items".
For example, if you had the following track on the Braille Sense U2: "Track 1 Chopin ?Fantasie Impromptu 1/10", "Track 1" indicates this file is the first item in the playlist. "Chopin ?Fantasie Impromptu" is the file name. "1/10" indicates this file is the first of ten files in the playlist.
