#     An FHEM Perl module for controlling Philips Audio Equipment connected to local network
#     such as MCi, Streamium and Fidelio devices.
#     The module provides basic functionality accessible through the port 8889 of the device:
#     (http://<device_ip>:8889/index).
#     e.g. NP3500, NP3700, NP3900.

    <br><br>
    This module controls a Philips Audio Player e.g. MCi, Streamium or Fidelio and (potentially) any other device including a navigation server.<br>
    To check, open the following URL in the browser: http://[ip # of your device]:8889/index
    <br><br>
    Currently implemented features:
    <br><br>
    <ul>
      <li>Power on/off</li>
      <li>Internet Radio Preset Selection</li>
      <li>Input selection</li>
      <li>Volume +/-</li>
      <li>Mute on/off</li>
      <li>...</li>
    </ul>
    <br>
    Defining a PHILIPS_AUDIO device will schedule an internal task (interval can be set
    with optional parameters &lt;off_status_interval&gt; and &lt;on_status_interval&gt; in seconds.<br>
    &lt;off_status_interval&gt; is a parameter used in case the device is powered off or not available.<br>
    &lt;on_status_interval&gt; is a parameter used in case the device is powered on.<br>
    If both parameters are unset, a default value 30 (seconds) for both is used.<br>
    If &lt;off_status_interval&gt; is set only the same value is used for both parameters.<br>
    Due to a relatively low-performance of the devices the minimum interval is set to 3 seconds.
    <br>
    The internal task periodically reads the status of the Network Player (power state, volume and mute status etc.) and triggers notify/filelog commands.
    <br><br>    
    Example:<br><br>
    <ul><br>
      Add the following code into the <b>fhem.cfg</b> configuration file and restart fhem:<br><br>
      <code>
      define PHAUDIO_player PHILIPS_AUDIO NP3900 192.168.0.15<br>

    <code>
      set &lt;name&gt; &lt;command&gt; [&lt;parameter&gt;]
    </code><br><br>
    Currently, the following commands are defined.<br>    
    <i>Note: Commands and parameters are case sensitive.</i><br>
      <ul><br><br>
      <u>Available commands:</u><br><br>
      <li><b>aux</b>&nbsp;&nbsp;-&nbsp;&nbsp; Switches to the AUX input (MP3 Link or similar).</li>
      <li><b>getInetRadioFavorites</b> &nbsp;&nbsp;-&nbsp;&nbsp; Reads the favorites. (May take some seconds...).</li>
      <li><b>getInetRadioPresets</b> &nbsp;&nbsp;-&nbsp;&nbsp; Reads the presets. (May take some seconds...).</li>
      <li><b>inetRadioFavorite</b> [1..24] &nbsp;&nbsp;-&nbsp;&nbsp; Selects an internet radio favorite (May take some seconds...).</li>
      <li><b>inetRadioPreset</b> [1..24] &nbsp;&nbsp;-&nbsp;&nbsp; Selects an internet radio preset (May take some seconds...).</li>
      <li><b>inetRadioFavoriteByName</b> [name] &nbsp;&nbsp;-&nbsp;&nbsp; Selects an internet radio favorite by name. (getInetRadioFavorites must be run previously for the command to become available.) (May take some seconds...).</li>
      <li><b>inetRadioPresetByName</b> [name] &nbsp;&nbsp;-&nbsp;&nbsp; Selects an internet radio preset by name. (getInetRadioPresets must be run previously for the command to become available.) (May take some seconds...).</li>
      <li><b>mute</b>&nbsp;&nbsp;-&nbsp;&nbsp; Mutes the device.</li>
      <li><b>unmute</b>&nbsp;&nbsp;-&nbsp;&nbsp; Unmutes the device.</li>
      <li><b>next</b> &nbsp;&nbsp;-&nbsp;&nbsp; Selects the next song, preset etc.</li>
      <li><b>play_pause</b> &nbsp;&nbsp;-&nbsp;&nbsp; Toggles PLAY/PAUSE.</li>
      <li><b>previous</b> &nbsp;&nbsp;-&nbsp;&nbsp; Selects the previous song, preset etc.</li>
      <li><b>repeat [single|all|off]</b> &nbsp;&nbsp;-&nbsp;&nbsp; Sets the repeat mode.</li>
      <li><b>shuffle [on|off]</b> &nbsp;&nbsp;-&nbsp;&nbsp; Sets the shuffle mode.</li>
      <li><b>standbyButton</b> &nbsp;&nbsp;-&nbsp;&nbsp; Toggles between standby and power on.</li>
      <li><b>statusRequest</b> &nbsp;&nbsp;-&nbsp;&nbsp; Updates the readings.</li>
      <li><b>stop</b> &nbsp;&nbsp;-&nbsp;&nbsp; Stops the player.</li>
      <li><b>volume</b> &nbsp;&nbsp;-&nbsp;&nbsp; Sets the relative volume 0...100%.</li>
      <li><b>volumeStraight</b> &nbsp;&nbsp;-&nbsp;&nbsp; Sets the absolute volume 0...64.</li>     
    </ul><br><br>

    A typical example is powering the device remotely and tuning the favourite radio station:<br><br>
    Add the following code into the <b>fhem.cfg</b> configuration file:<br><br><br>
    <ul>
      <code>
        define PHAUDIO_player PHILIPS_AUDIO NP3900 192.168.0.15 30 5<br>
        attr PHAUDIO_player webCmd volume:mute:inetRadioPreset
      </code>
    </ul><br><br>
    Add the following code into the <b>99_MyUtils.pm</b> file:<br><br>
    <ul>
      <code>
        sub startMyFavouriteRadioStation()<br>
        {<br>
          &nbsp;&nbsp;fhem "set PHAUDIO_player inetRadioPreset 1";<br>
          &nbsp;&nbsp;sleep 1;<br>
          &nbsp;&nbsp;fhem "set PHAUDIO_player volume 30";<br>
        }
      </code>
    </ul>
    <br><br>
    It's a good idea to insert a 'sleep' instruction between each fhem commands due to internal processing time of the player. Be patient when executing the commands...<br><br>

    Now the function can be called by typing the following line in the FHEM command line or by the notify-definitions:<br><br>
    <ul>
      <code>
        {startMyFavouriteRadioStation()}<br><br>
      </code>
    </ul>

  <b>Get</b>
  <ul>
    <code>
      get &lt;name&gt; &lt;reading&gt;
    </code>
    <br><br>
    Currently, the 'get' command returns reading values only. For a specific list of possible values, see section <b>"Generated Readings"</b>.<br><br>

  <b>Implementer's note</b><br><br>
    <ul>
    Trivial: In order to use that module the network player must be connected to the Ethernet.<br>
    There's no possibility to read back the current power on/standby status from the device. This fuctionality is missing in the server application.<br>

    Mit Hilfe dieses Moduls lassen sich Philips Audio Netzwerk Player wie z.B. MCi, Streamium oder Fidelio via Ethernet steuern.<br>
    Theoretisch sollten alle Ger&auml;te, die &uuml;ber einer implementierten HTTP Server am Port 8889 haben (http://[ip Nummer des Ger&auml;tes]:8889/index), bedient werden k&ouml;nnen.<br>
    <br>
    
    Die aktuelle Implementierung erm&ouml;glicht u.a. den folgenden Funktionsumfang:<br><br>
    <ul>
      <li>Power on/off</li>
      <li>Internet Radio Preset Auswahl</li>
      <li>Input Auswahl</li>

    <br>
    Eine PHILIPS_AUDIO Definition initiiert einen internen Task, der von FHEM zyklisch abgearbeitet wird.<br>
    Das Intervall (in Sekunden) kann f&uuml;r die Zust&auml;nde &lt;on_status_interval&gt; und &lt;off_status_interval&gt; optional gesetzt werden.<br>
    &lt;off_status_interval&gt; steht f&uuml;r das Intervall, wenn das Ger&auml;t ausgeschaltet/abwesend ist.<br>
    &lt;on_status_interval&gt; steht f&uuml;r das Intervall, wenn das Ger&auml;t eingeschaltet/verf&uuml;gbar ist.<br>
    Wenn keine Parameter angegeben wurden, wird ein Default-Wert von 30 Sekunden f&uuml;r beide gesetzt.<br>
    Wenn nur &lt;off_status_interval&gt; gesetzt wird, gilt dieser Wert f&uuml;r beide Zust&auml;nde (eingeschaltet/ausgeschaltet).<br>
    Der Task liest zyklisch grundlegende Parameter vom Player und triggert notify/filelog Befehle.<br>
    Aufgrund der recht schwachen Rechenleistung der Player wurde das minimale Intervall auf 3 Sekunden beschr&auml;nkt.<br><br>

  <ul>
    Trivial: Um das Ger&auml;t fernbedienen zu k&ouml;nnen, muss es an das Ethernet-Netzwerk angeschlossen und erreichbar sein.<br>
    Es gibt keine M&ouml;glichkeit, den Zustand Power-on/Standby des Ger&auml;tes abzufragen. Diese Limitierung liegt auf Seiten des Ger&auml;tes.<br>
