ID and Flag Values

The following tables list important ID and flag values used in the AMS.

**Table A-1** RemoteCommandID values
Name	Value
`RemoteCommandIDPlay`	0
`RemoteCommandIDPause`	1
`RemoteCommandIDTogglePlayPause`	2
`RemoteCommandIDNextTrack`	3
`RemoteCommandIDPreviousTrack`	4
`RemoteCommandIDVolumeUp`	5
`RemoteCommandIDVolumeDown`	6
`RemoteCommandIDAdvanceRepeatMode`	7
`RemoteCommandIDAdvanceShuffleMode`	8
`RemoteCommandIDSkipForward`	9
`RemoteCommandIDSkipBackward`	10
`RemoteCommandIDLikeTrack`	11
`RemoteCommandIDDislikeTrack`	12
`RemoteCommandIDBookmarkTrack`	13
Reserved	14-255

**Table A-2** EntityID values
Name	Value
`EntityIDPlayer`	0
`EntityIDQueue`	1
`EntityIDTrack`	2
Reserved	3-255

**Table A-3** EntityUpdateFlags
Name	Value
`EntityUpdateFlagTruncated`	(1 << 0)
Reserved	(1 << 1) - (1 << 7)

**Table A-4** PlayerAttributeID values
Name	Value	Format
`PlayerAttributeIDName`	0	A string containing the localized name of the app.
`PlayerAttributeIDPlaybackInfo`	1	A concatenation of three comma-separated values: PlaybackState: a string that represents the integer value of the playback state: `PlaybackStatePaused` = 0 `PlaybackStatePlaying` = 1 `PlaybackStateRewinding` = 2 `PlaybackStateFastForwarding` = 3 PlaybackRate: a string that represents the floating point value of the playback rate. ElapsedTime: a string that represents the floating point value of the elapsed time of the current track, in seconds, at the moment the value was sent to the MR.
`PlayerAttributeIDVolume`	2	A string that represents the floating point value of the volume, ranging from 0 (silent) to 1 (full volume).
Reserved	3-255

Using the following formula at any time, the MR can calculate from the Playback Rate and Elapsed Time how much time has elapsed during the playback of the track:

CurrentElapsedTime = ElapsedTime + ((TimeNow – TimePlaybackInfoWasReceived) * PlaybackRate)

This lets MRs implement and display a UI scrubber without needing to poll the MS for continuous updates.

**Table A-5** QueueAttributeID values
Name	Value	Format
`QueueAttributeIDIndex`	0	A string containing the integer value of the queue index, zero-based.
`QueueAttributeIDCount`	1	A string containing the integer value of the total number of items in the queue.
`QueueAttributeIDShuffleMode`	2	A string containing the integer value of the shuffle mode. Table A-6 lists the shuffle mode constants.
`QueueAttributeIDRepeatMode`	3	A string containing the integer value value of the repeat mode. Table A-7 lists the repeat mode constants.
Reserved	4-255

**Table A-6** Shuffle Mode constants
Name	Value
`ShuffleModeOff`	0
`ShuffleModeOne`	1
`ShuffleModeAll`	2
Reserved	3-255

**Table A-7** Repeat Mode constants
Name	Value
`RepeatModeOff`	0
`RepeatModeOne`	1
`RepeatModeAll`	2
Reserved	3-255

**Table A-8** TrackAttributeID values
Name	Value	Format
`TrackAttributeIDArtist`	0	A string containing the name of the artist.
`TrackAttributeIDAlbum`	1	A string containing the name of the album.
`TrackAttributeIDTitle`	2	A string containing the title of the track.
