When you have spent over ten minutes searching on IPTV, you are likely to have come across three words which are likely to have been used more than once, STBEmu, Stalker IPTV and Xtream. The majority of guides consider them to be interchangeable. They aren't. By knowing the difference between an IPTV portal, the Stalker middleware protocol and the Xtream Codes API, you will save some hours of frustration and be able to select the right setup that fits your needs.
What Is an IPTV Portal and Why It Is Important
The one that is placed between the streaming provider server and your device is an IPTV portal, a web-based interface. You can consider it as the door to a streaming service. By entering a portal URL into the app or set-top box, you are communicating to a middleware layer which will validate your account, deliver your channel list and control your session.
The portal address is usually of the format of youriptvprovider.com/c/ or some variation. It is not possible to access the content without a valid portal URL, which in the vast majority of cases is also a valid MAC address. The portal takes care of on-demand libraries to electronic program guides (EPGs) hence the end result of your viewing experience is directly influenced by the quality of the portal infrastructure.
STBEmu and Stalker IPTV Protocol
STBEmu (Set-Top Box Emulator) is an Android app that is able to mimic the behavior of a Mag set-top box. Infomir manufactures mag devices which are based on the Stalker middleware platform as firmware, an open-source portal system that was originally created to support cable operators.
In setting up STBEmu, you are informing your Android device (be it phone or tablet) to act as a physical Mag box. The app reads a MAC address (the MAC of your device or a manually typed one) and logs in to a portal of Stalker IPTV. The Stalker protocol is based on HTTP, it transfers tokens and session information between the client and the portal server.
The portal URL, MAC address and time zone are considered to be important STBEmu settings. The distinction between a working setup and an infinite authentication loop is having these three details correct. The Stalker portal format is very standardized and this is the reason why the STBEmu is compatible with hundreds of different providers all of whom have compatible middleware.
A noticeable point: they need to make sure that the MAC address you fill in is registered with your provider or it is within the scope of your provider. Any MAC address with a random value will trigger either a Portal is not available or STB is blocked error.
Xtream Codes IPTV: An alternative
Xtream Codes IPTV is also based on a different architecture. Xtream does not follow the footsteps of a set-top box and MAC-based authentication but has a simple URL-based username and password system alongside a panel URL.
Xtream API was created initially as an IPTV provider management panel. It was also an extremely popular streaming protocol due to its simplicity over time. There are three things required to connect to an Xtream-compatible service, namely, a server URL (sometimes referred to as the host), a username, and a password.
The Xtream form provides content in three formats which include live television channels, video on demand (VOD) and series. Xtream Codes are natively supported in most of the existing IPTV applications, such as TiviMate, IPTV Smarters and GSE Smart IPTV. An Xtream server may also be used to create an M3U playlist using the URL format such as http://server:port/get.php?username=USER&password=PASS&type=m3u.
It is not insignificant based on the provider side of the Stalker/STBEmu and Xtream. Stalker portals are generally more resource-consuming to operate and need MAC address management. The Xtream panels are more scaled and this is one of the reasons why many providers have transitioned to Xtream based infrastructure in the past few years.
Stalker IPTV vs. Xtream Which One to use?
It will all be up to what your provider will support.
When your provider supplies you with a portal URL and MAC address, then you have Stalker IPTV. The most downloaded free app with this configuration on Android is STBEmu. It is also possible to use a real Mag box or other Stalker-friendly clients.
In the event that your provider provides you with a server URL, user and password, then you are dealing with an Xtream Codes IPTV setup. Applications such as TiviMate or IPTV Smarters will work best in this situation with full EPG support, catch-up TV and a well-structured interface.
Other providers offer both protocols simultaneously to provide the customer with flexibility in their connection. Not sure what type of format you are subscribing to? View your welcome email or reach out to the support of your provider and they will provide you with the specific credentials and type of app that you need to utilize.
How to install your IPTV Portal properly
Whether you are using STBEmu and a Stalker portal or an app based around Xtream, there are a few principles that are common to all.
To begin with, connection stability is more important than the choice of the app. Through a solid wired or high speed wifi connection (25 Mbps or higher to stream HD, 50Mbps or higher to stream 4K) most of the buffering problems that individuals mistakenly attribute to the app or portal can be avoided.
Second, use a trusted DNS. There are ISPs which throttle or block IPTV traffic. The simplest change that can be performed is to change the DNS of your device to a public resolver such as 1.1.1.1 or 8.8.8.8, and nothing more.
Third, keep your app updated. The Stalker and the Xtream protocols have been incrementally updated. Operating a version of STBEmu or your Xtream client that is older than the current version will result in authentication problems when the providers upgrade their server software.
Knowledge of the correlation between an IPTV portal, the Stalker middleware, STBEmu, and Xtream Codes will have a practical benefit when troubleshooting or selecting a new provider. They are not mere buzzwords, they are specific technical systems, and the understanding of which one one is at any given moment in time makes each and every step of the process much clearer.
