Player ID
There are two ways a server can identify the player by its 128-bit UUID (in 8-4-4-4-12 lower-case hex string format). Server finds the UUID in the following ways.
Content Source Macro
Each player as a "Content Source" setting configured to point to an URL loaded at boot time. The URL can contain a macro {$player-id} that is replaced with the player's UUID.
For example, player with ID "f1835d9f-be8f-4054-9e6c-123456789012" configured to load from
http://server.com/player-{$player-id}/index.smil
loads the following actual URL at boot time:
http://server.com/player-f1835d9f-be8f-4054-9e6c-123456789012/index.smil
Another macro that is available is {$fw-version} which gives the firmware version of the player.
Note: this feature is only available in player firmware version 1.4.7 and later.
User-Agent Header
A-SMIL players use the HTTP "User-Agent" header to report its ID to server. Each player reports two pieces of information in this process: a 128-bit UUID and a player name (configurable by the user).
The player formats its User-Agent string in the following format:
User-Agent: ADAPI/{$APIVersion} (UUID:{$playerId}; NAME:{UrlEncode(UTF8($playerName))}) {$firmwareFamily}/{$firmwareVersion}
For example, for a player with player ID "f1835d9f-be8f-4054-9e6c-123456789012" and player name "12:34:56:78:90:12", the User-Agent header may look like:
User-Agent: ADAPI/1.0 (UUID:f1835d9f-be8f-4054-9e6c-123456789012; NAME:12%3A34%3A56%3A78%3A90%3A12) SMP863X-ADAPI/1.3.2
