# Ultimate Backend (Kodi Add-on)

**Ultimate Backend** is a background service for **Kodi** that provides a local API for **live TV streaming**, **EPG data**, and **manifest management** from supported online TV providers.

It acts as the **bridge between streaming services and Kodi's PVR system**, designed specifically to work together with the official **PVR IPTV Simple Client**.

---

## 🎯 Purpose

This add-on runs a small local web service inside Kodi.
It:
- Logs in to supported streaming providers
- Retrieves live channel lists and EPG data
- Rewrites DASH manifests for Kodi playback
- Generates M3U playlists compatible with PVR IPTV Simple

Once configured, your live TV channels from streaming platforms appear directly in Kodi's **TV** section — complete with EPG, logos, and DRM handling.

## 🧠 Using with PVR IPTV Simple Client

The **Ultimate Backend** add-on is designed to work **together with PVR IPTV Simple Client**

### Setup Steps

1. In Kodi, go to:
   **Add-ons → My Add-ons → PVR Clients → PVR IPTV Simple Client → Configure**

2. Under **General → Location**, select:
   🟢 *Remote Path (Internet address)*

3. **Recommended:** Use provider-specific M3U URLs for better performance and organization:

   **For Joyn DE:**
   M3U Playlist URL: http://localhost:7777/api/providers/joyn_de/m3u
   EPG XMLTV URL: http://localhost:7777/api/providers/joyn_de/epg

   **For Joyn AT:**
   M3U Playlist URL: http://localhost:7777/api/providers/joyn_at/m3u
   EPG XMLTV URL: http://localhost:7777/api/providers/joyn_at/epg

   **For RTL+:**
   M3U Playlist URL: http://localhost:7777/api/providers/rtlplus/m3u
   EPG XMLTV URL: http://localhost:7777/api/providers/rtlplus/epg

   *Alternatively, you can use the combined playlist (not recommended for multiple providers):*
   M3U Playlist URL: http://localhost:7777/api/m3u

4. Save and restart Kodi's PVR subsystem (or Kodi itself).
   Your live TV channels will now appear in Kodi's **TV** section.

⚠️ **Note:** EPG (Electronic Program Guide) data will be available in a future version. Currently, channels will be displayed without program information.

💡 **Tip:**
To regenerate and cache the latest M3U playlist manually, open these URLs in your browser:
- Provider-specific: http://localhost:7777/api/providers/joyn_de/m3u/generate
- All providers: http://localhost:7777/api/m3u/generate

This forces the backend to rebuild and cache the playlist for faster future loading.
