= Functional Specification =
PC = non-mobile device, such as a Linux or Windows desktop
MID = Mobile Internet Device.
Content = music files (mp3, etc), movies (.mpg, etc), photos (.jpg, etc)
Media viewer = Multimedia application on MID

1 Content Management on the PC
• New: MID Content Management Application (new)
• Windows Media Player
• ITunes
• Banshee

2 Getting content to the device
2.1 Syncing
• Auto-sync with an application that manages content on the PC. This involves writing a new plugin or application that pushes the content from one of the following applications to the MID when the MID is plugged in via USB.
o Only sync down (all content is pushed to MID. Any MID content changes are lost
o Sync in both directions: content is merged on PC and MID. Conflicts are resolved by asking user for preference.
• Auto-sync with a file directory on the PC (just file system). Application registered when MID is plugged in to USB to auto-sync contents.
• Manual-sync: Plug MID into USB port. MID file system exposed to PC. User drags/drops files from PC to the MID file system.
2.2 Sharing
• Auto-detect other MIDs in area via bluetooth. Connect. Display shared content from each MID on other MID. User can download content to their MID.
• Receive email with content. Save content to MID filesystem.
2.3 Manual
• Download content from internet via the browser
• Download content from wired or wireless connection to remote filesystem over network

3 Content Management on MID

User can:
• View content name, artist, album, length, genre, music type, rating, times played, last played date/time
• View content as list
• View content as thumbnails (album art for music, cover-art for movies or frame from movie, small image for photos)
• View content as resizable thumbnails
• View 3D-flipping album art
• Select content
• Select multiple files at the same time
• Organize content folders, create new folders, name folders, move content between folders
• Assign content metadata: Name, Artist, Album, genre, rating, cover art
• Auto-lookup music metadata online from CDDC: Name, artist, album, cover art
• Create, delete, edit playlists
• Rate content
• Sort music by: Name, Date, length, Artist, Album, genre, type (mp3, wav, etc), rating
 Slideshow
• Create a slideshow of photos
• Assign a music file to play when slideshow is started
• Assign a music playlist to play when slideshow is started
• Set the time delay between photo transitions
• Set transition effect between pictures (fade, slide, etc)

4 Content Playback on MID
User can:
• Play content
• Pause content
• Play content at double speed forward and backward
• Play content at variable speed forward and backward
• Jump to beginning of content
• Jump to end of content
• Stop content
• View progress of content playback
• View time content has been playing
• Jump to location within the content by moving the progress thumb to a new location

 Video
• Play full screen video
• Pause and restart full screen video without leaving full screen
 Audio
• Show visualizations while playing audio
• Show visualizations full screen while playing audio
• Start audio and play it in the background while performing other tasks
• Easily pause audio that is playing in the background
 Photo
• Show photos full screen.
• Navigate to next and previous photos
• Play slideshow
• Pause full screen slideshow and restart without leaving full screen

5 Internet Radio
User can:
• Create, edit, and delete internet radio stations
• Select a station and listen to streaming audio
• Add a new internet radio station from inside the browser.

6 Content
• Media viewer will support mechanism for applications to register for certain content types and show buttons to launch these applications when the content of the registered type is selected. Plugin applications will be started with the paths to all the content as command-line parameters. Examples include internet upload, email, or any application to manipulate content.

7 Theme / Skin
• Media viewer will use the system theme for all standard Hildon and GTK controls such as buttons, scrollbars, and dialogs.
• User can change the skin of the MID media viewer

8 Media Engine
• Media viewer will be capable of using gstreamer or helix media playback engines
• User can select which media engine to use first, or exclusively
• Media viewer will dynamically discover what content types each media engine supports and attempt to playback content on the correct engine
• Media viewer will show a symbol on content that is not supported by any media engines

Summary

The media player application for mobile devices. This is not the spec for the underlying engine (e.g. gstreamer, helix, etc). The media player for UME will have a finger-navigable UI capable of viewing photos, playing music and videos, and using either the gstreamer or helix media engines with a common interface to them. The UI will follow the recommendations in the [WWW] UI Style Guide

Rationale

There are many media applications but none seemed to cover all of the features needed and be tailored for a MID, so a new UI is being written. The goal is to simplify the media management on the MID and provide a single place for viewing and listening to media.

The entire scope of media management is large, from the first time a user obtains some content to consuming it on the device. The following section describes the full spectrum with the ones outside the of content all of these pieces and details those ones are accomplished by the UME media player. Additional functionality may be added as time and resources permit.

= Functional Specification = PC = non-mobile device, such as a Linux or Windows desktop MID = Mobile Internet Device. Content = music files (mp3, etc), movies (.mpg, etc), photos (.jpg, etc) Media viewer = Multimedia application on MID
