- Connects using Portal URL + MAC address (Stalker middleware), different from Xtream Codes or M3U.
- Works on Android phones, Android TV, Nvidia Shield, Fire Stick (sideload), and other Android-based devices.
- Ideal for users who prefer the MAG portal interface or whose provider uses MAC-based authentication.
- IPTV US Canada supports both portal/MAC and Xtream Codes connections for maximum compatibility.
What Is STB Emu?
STB Emu (short for Set-Top Box Emulator) is an Android application that replicates the functionality and interface of physical MAG set-top boxes. MAG boxes — manufactured by Infomir — are dedicated IPTV hardware devices widely used by IPTV providers around the world. They connect to Stalker middleware servers using a portal URL and a unique MAC address for authentication.
STB Emu eliminates the need to purchase a physical MAG device by emulating the exact same Stalker portal interface on any Android device. When you open STB Emu, you see the same menu system, channel navigation, EPG layout, and VOD browser that you would see on a MAG 254, MAG 322, or MAG 524 hardware box. The interface is controlled entirely with a remote control, making it feel identical to the hardware experience.
The key difference between STB Emu and other IPTV players like TiviMate or IPTV Smarters Pro is the authentication method. While TiviMate and Smarters use Xtream Codes API (server URL + username + password), STB Emu uses portal-based authentication (portal URL + MAC address). Some IPTV providers exclusively use one method, while providers like IPTV US Canada support both, giving you the freedom to choose whichever player you prefer.
STB Emu is particularly popular among users who are transitioning from physical MAG boxes to Android-based streaming devices. If you have been using a MAG box and want to switch to a Fire Stick or Android TV box without changing the viewing experience, STB Emu provides a seamless transition with the same familiar interface.
How Portal/MAC Authentication Works
Understanding the portal and MAC address system is essential for using STB Emu. Here is how the authentication process works and how it differs from Xtream Codes.
Portal URL (Stalker Middleware)
The portal URL is the address of the Stalker middleware server that hosts your IPTV service. It is typically in the format http://yourprovider.com:port/c/. When STB Emu connects to this URL, the server provides the full interface — channel list, categories, EPG, VOD catalog — just like a web server serves a website.
The portal server controls what you see and how the content is organized. Different providers may have different portal layouts, color schemes, and menu structures. IPTV US Canada provides a portal URL optimized for the best navigation experience.
MAC Address Authentication
Instead of username and password, portal-based IPTV uses a MAC address (Media Access Control address) to identify your device. STB Emu generates a virtual MAC address in the format 00:1A:79:XX:XX:XX when you first install the app.
This MAC address must be registered with your IPTV provider before the portal will allow access. Either you share your MAC address with IPTV US Canada support for activation, or the provider assigns you a specific MAC address to enter in STB Emu. Once matched, the portal authenticates your connection.

Features & Interface
STB Emu replicates the full MAG box experience with all the features you would find on physical hardware. The interface is server-driven, meaning the portal controls the layout and organization.
MAG Portal Interface
Full replication of the Stalker portal interface used by MAG 254, 322, 420, and 524 devices. The same menu system, navigation, and layout. Users transitioning from physical MAG boxes will feel immediately at home.
Multiple Profiles
Create and manage multiple profiles, each with its own portal URL and MAC address. Switch between different IPTV providers or portal configurations without re-entering credentials. Available in the Pro version.
Built-in EPG
The Electronic Program Guide is integrated into the portal interface. View current and upcoming programs directly from the channel list or in a dedicated EPG screen. EPG data is provided by the portal server.
VOD & Series Library
Access the provider's on-demand library through the portal interface. Browse movies and TV series organized by genre, year, and category. Search for specific titles within the portal.
Timeshift & Catch-Up
Pause, rewind, and fast-forward live TV using the timeshift buffer. Catch-up TV allows rewatching past programs on supported channels. These features depend on portal server support.
Channel Favorites
Mark channels as favorites from the channel list for quick access. Navigate to the Favorites section from the main menu to see only your preferred channels without scrolling through the full list.
Subtitle Support

Settings Optimization
Optimize these STB Emu settings for the best performance and streaming quality with your IPTV US Canada portal connection.
Video Decoder
Hardware (auto)Hardware decoding uses your device GPU for smooth 4K playback. The auto setting selects hardware when available and falls back to software for unsupported codecs. Only force software decoding if you see green screen or video artifacts.
Buffer Size
3 to 5 secondsIncrease the buffer from the default to reduce micro-buffering during peak hours. The portal interface may require a slightly larger buffer than Xtream Codes connections due to how Stalker middleware handles streams.
Aspect Ratio
Auto / 16:9Leave on Auto for most content. Override to 16:9 if you see black bars on content that should fill the screen. Some older SD channels may display better with 4:3 selected.
Audio Output
Stereo or PassthroughUse Stereo for TV speakers. Enable Passthrough if connected to a soundbar or AV receiver to pass Dolby Digital (AC3) and DTS audio directly to the external audio system.
Portal Refresh
On app restartThe portal data refreshes when you restart the app. For the freshest channel list and EPG data, exit STB Emu completely and reopen it. Do not leave the app running in the background for extended periods.
Screen Resolution
Match device outputSet your Android device output resolution to match your TV (usually 4K or 1080p). STB Emu inherits this setting. Higher resolution output means sharper portal interface and EPG text.
Troubleshooting Common Issues
Having trouble with STB Emu? These are the most common issues and their solutions.
Portal Not Connecting / Error Loading
Verify the portal URL is entered exactly as provided — including http:// prefix, port number, and trailing path (/c/). Check that your MAC address is activated with your provider. Ensure your internet connection is working. Try force-closing and restarting STB Emu.
MAC Address Not Accepted
The MAC address must be in the format 00:1A:79:XX:XX:XX. If your provider assigned a specific MAC, enter it exactly. If using the auto-generated MAC, share it with IPTV US Canada support and wait for activation confirmation before connecting.
Buffering / Freezing During Playback
Increase the buffer size in STB Emu settings. Switch to a wired Ethernet connection. Enable a VPN to bypass ISP throttling. Close other apps running in the background. If on Fire Stick, ensure no system updates are downloading.
Black Screen with Audio Only
The video decoder may not support the stream codec. Switch the video decoder from Hardware to Software in settings. If using Hardware, try the alternative hardware decoder option. Update your device firmware for better codec support.
No EPG Data Showing
EPG in STB Emu is provided by the portal server, not the app. If EPG is missing, the portal may not include EPG for your subscription level. Contact IPTV US Canada support to confirm EPG is included with your portal connection.
App Crashing After Portal Change
When changing portal URLs or MAC addresses, always restart the app completely. Clear the app cache in Android Settings > Apps > STB Emu > Clear Cache. If crashes persist, clear data (this resets all settings) and reconfigure from scratch.
Remote Control Keys Not Working
STB Emu uses standard Android TV remote mappings. On Fire Stick, the menu button opens the STB Emu settings overlay. If certain keys do not work, go to STB Emu Settings > Remote Control Mapping and reassign buttons to match your remote layout.
Portal Says Too Many Connections
This means too many devices are using the same subscription simultaneously. Check your IPTV US Canada plan — Silver allows 1 device, Gold allows 2, Diamond allows 3. Close STB Emu on other devices or upgrade your plan for more simultaneous connections.
STB Emu vs Alternative Apps
STB Emu serves a specific niche — portal/MAC-based IPTV. Here is how it compares to other popular IPTV players to help you decide which is right for your setup.
| Feature | STB Emu | TiviMate | Smarters Pro | IBO Player |
|---|---|---|---|---|

Our recommendation: Use STB Emu if you prefer the MAG portal experience or are migrating from a physical MAG box. For the most feature-rich experience, TiviMate with Xtream Codes is the better choice. For cross-platform compatibility, use IPTV Smarters Pro.
Frequently Asked Questions
STB Emu (STB Emulator) is an Android application that emulates MAG set-top boxes. It replicates the Stalker portal interface, allowing you to use portal-based IPTV services on any Android device or Fire Stick without needing dedicated MAG hardware. The app connects to your IPTV provider using a portal URL and MAC address, the same way a physical MAG box would.
Yes. STB Emu works on all Amazon Fire Stick and Fire TV devices. However, it is not available on the Amazon App Store, so you need to sideload it using the Downloader app or by transferring the APK file. The sideloading process takes about 2 minutes and is the same method used for TiviMate.
Open STB Emu and go to Settings (gear icon) then select Profiles. The MAC address is displayed at the top of the profile screen in the format 00:1A:79:XX:XX:XX. You can also view it on the app's loading screen. This MAC address can be customized if your provider requires a specific one, or you can share it with IPTV US Canada support for portal activation.
STB Emu has a free version with basic features and ads. The Pro version (STB Emu Pro) is a one-time paid upgrade that removes ads, supports multiple profiles, and provides additional customization options. The Pro version is recommended for users who use STB Emu as their primary IPTV player.
A portal URL connects to a Stalker middleware server that provides the MAG-style interface with categories, EPG, and VOD organized by the server. An M3U URL is a simple playlist file containing channel links. STB Emu is designed primarily for portal URL connections, while apps like IPTV Smarters Pro and TiviMate are better suited for M3U and Xtream Codes connections.
Use STB Emu if your IPTV provider uses a portal/Stalker middleware system with MAC-based authentication. Use IPTV Smarters Pro if your provider uses Xtream Codes API with username and password login. IPTV US Canada supports both connection methods, so you can choose either app based on your preference.
Yes. STB Emu runs on Android phones and tablets with Android 5.0 or higher. However, the MAG-style interface is designed for TV screens and remote control navigation. The experience on a phone screen is functional but not optimized for touch input. For mobile IPTV, IPTV Smarters Pro or IBO Player provide a better touch-friendly interface.
Open STB Emu, go to Settings then Profiles. Tap on the active profile. You will see the MAC address field. Tap it and enter the new MAC address in the format 00:1A:79:XX:XX:XX. Save the profile and restart the app. Your provider may need to whitelist the new MAC address on their server before it works.
