General

With the Webinterface you can Control your Box using a Browser. The Dreambox Webinterface (short WebIf) is included in all newer Images. The latest version of the WebIf can be obtained via CVS. You can also use the Webinterface API in your 3rd Party Applications to control the box or display information.

You can reach the WebIf by pointing your Browser to the IP if your Box (e.g. 192.168.0.21), or if name resolution works by calling http://dreambox.

Technical

The Webinterface is fully embedded into enigma2. It is able to use ANY functionality and obtain ANY Information enigma2 can deliver.

Concept

The Webinterface works with a Client-/Server based Concept. The Webinterface Plugin provides you with 2 Major things.

  1. A Client API which you can access with any client (html/javascript, c++, java) you want to
    1. Control your Box and obtain Information for Channels (EPG, Timers, Recorded Movies, etc)
    2. Results are returned as xml
  2. A http client you can use with your browser

Live Updates

One of the major Improvements compared to the Webinterface of enigma1 is the Live-Update functionality. Changes can be automatically delivered to the webinterface without polling the server or reloading the whole page. This is realized by using a never ending Connection which is used to execute the DOM-Manipulation cmds. 

<script>parent.set("CurrentTime", "19:46:32");</script>
<script>parent.set("CurrentService", Channelname(19.2?E)");</script>
<script>parent.set("Event_Now_Name", "Name of Current event");</script>
<script>parent.set("Event_Now_Extended_Description", "Extended description of current event");</script>
<script>parent.set("Event_Now_Begin", "19:40");</script>
<script>parent.set("Event_Now_Remaining", "+28 min");</script>
<script>parent.set("Event_Next_Name", "Name of next Event");</script>
<script>parent.set("Event_Next_Begin", "20:15");</script>
<script>parent.set("Event_Next_Remaining", "60 min");</script>
<script>parent.set("Event_Next_Extended_Description", "Extendes description of next event");</script>

Client API

The API can be used by making http requests to your Box. As described above every request will usually result in a valid xml response.

To select a specific audio track you first have to find out its id via the "getaudiotracks" command. Then use the id as a parameter on this command:

Request:

  • http://IP_of_your_box/web/selectaudiotrack?id=2

or via Telnet:

  • wget -q -O - http://127.0.0.1/web/selectaudiotrack?id=2

Result: 

<?xml version="1.0" encoding="UTF-8"?>
<e2result>Success</e2result>

In case you issued an invalid (non-existing) id you get this result: 

<?xml version="1.0" encoding="UTF-8"?>
<e2result>Error</e2result>

The services within a bouquet are requested by specifying the service reference. The service reference of the last bouquet from above is: 

1:7:1:0:0:0:0:0:0:0:FROM BOUQUET "userbouquet.favourites.tv" ORDER BY bouquet

so the request is:

  • http://IP_of_your_box/web/getservices?sRef=1:7:1:0:0:0:0:0:0:0:FROM BOUQUET "userbouquet.favourites.tv" ORDER BY bouquet

or via Telnet (replace all spaces with %20 and the " with %22):

  • wget -q -O - http://127.0.0.1/web/getservices?sRef=1:7:1:0:0:0:0:0:0:0:FROM%20BOUQUET%20%22userbouquet.favourites.tv%22%20ORDER%20BY%20bouquet

Result is: 

<?xml version="1.0" encoding="UTF-8"?>
<e2servicelist>
   <e2service>
      <e2servicereference>1:0:1:6DCA:44D:1:C00000:0:0:0:</e2servicereference>
      <e2servicename>Das Erste</e2servicename>
   </e2service>
   <e2service>
      <e2servicereference>1:0:1:6D66:437:1:C00000:0:0:0:</e2servicereference>

      <e2servicename>SAT.1</e2servicename>
   </e2service>
   ...
</e2servicelist>

If there are headers within the bouquet an <e2service> entry looks like this: 

<e2service>
    <e2servicereference>1:64:A:0:0:0:0:0:0:0::Premiere-Star---Astra(19.2E)---------------------------------------------------------</e2servicereference>
