Through the internet based systems, millions of people are watching television instead of the satellite dishes or cable boxes. The technology that has been used in this shift has a name: IPTV, or the Internet Protocol Television. The details of how it works actually, namely, the purpose of such a tool, as Stalker Portal, STB Emulator (STBemu), and Xtream Codes are valuable to make an informed, educated choice regarding their streaming configuration.
This article takes each of these components, the ways in which they are interrelated, and how that determines what is considered a legitimate use of the technology and what is considered a problematic use of the technology.
What IPTV Actually Is
IPTV transmits television via an internet connection rather than the traditional broadcast signals. Instead of a set timetable of broadcasting, content is on-demand or broadcast in real-time via a server, and accessed by any device with an internet connection. The background technology is the same as legal platforms such as Hulu Live, YouTube TV, and Sling.
The three parts of the ecosystem that are needed to work are a content server, a communication protocol, and a client application. Three of the most popular formats of bridging those parts together are the stalker portal, STBemu, and xtream formats.
Stalker Portal: What It Does
The Stalker Portal is a middleware platform which was initially created by Infomir. It was to be used to control the delivery of IPTV services between a server of the provider and a set-top box of the subscriber. The portal manages the authentication of the subscribers, channel management, video-on-demand (VOD) libraries and electronic program guides (EPG).
Stalker Portal is operated on a provider back-end. Upon connection, each user is sent a MAC address by his device to the portal server where the subscription is verified and an individualized set of channels is provided. The communication is on top of HTTP and the portal is based on a particular API structure that is implemented by client applications, such as STB Emulator.
Stalker Portal protocol identifies the device with the help of its MAC address instead of a username/password. It is a significant technical difference: it is associated with access to a hardware identity, as opposed to a credential.
STB Emulator (STBemu): The Software Bridge
STB Emulator (also known as STBemu) is an Android emulator that emulates the functionality of a real set-top box. It will make smartphones, tablets, Android TV boxes, and Fire TV sticks act like devices specifically designed to run IPTV - full support of the Stalker Portal.
With an appropriate portal URL and MAC address, STBemu will connect to the server of the IPTV provider, verify the session, and then it will load the entire channel interface. The application promotes such capabilities as parental restrictions, display of EPG, browsing VOD, and the use of multiple screens. The Google Play Store provides it publicly and it is consumed by the honest IPTV subscribers as well as in certain instances illegal services.
The technical role of STBemu is indifferent. It is a client application. The content that the IPTV it is connected to is licensed correctly is a matter of the provider and not the software.
Xtream Codes: The Second great IPTV Protocol
Whereas Stalker Portal implements the MAC-based authentication, Xtream Codes (also known as Xtream IPTV or Xtream API) implements a simpler credential model: a server URL, a username, and a password. This format has emerged one of the most popular IPTV delivery protocols in the world.
The appearance of an Xtream Codes playlist is normally as follows:
http://server-address:port/get.php?username=USER&password=PASS&type=m3u_plus
This creates an M3U playlist file which any possible player can open. Applications such as Tivimate, IPTV Smarters, and GSE Smart IPTV are directly compatible with Xtream Codes login. The format divides live channels, VOD content and series into different sections making the large content libraries manageable.
In 2019, Xtream Codes received high publicity as Italian police shut down the initial portal in a massive operation that focused on unauthorized IPTV distribution. Nonetheless, the API format that it developed became an industry standard that remains in use by legitimate providers and unlicensed operators.
Stalker Portal vs Xtream: Major Dissimilarities
The architecture of the two protocols is different, although they have similar purposes. Stalker Portal is more appropriate when the operator wants to operate on a large scale with MAC-level device control and a complete middleware interface. Xtream Codes is thinner, faster to install, and is more mobile - one set of credentials can be used with dozens of apps without any device-specific configuration.
Both are supported by the majority of professional IPTV providers. The subscriber can be given a Stalker Portal URL that may be used with STBemu on their television box and an Xtream username/password that can be used with a mobile device.
Law and Conscionable use
All the technologies mentioned above IPTV, the Stalker Portal, STBemu, and Xtream Codes are not illegal in their nature. They are the modes of delivery. The legality of the same is solely based on the licensing agreements of the content provider with the broadcasters and rights holder.
Official IPTV providers are paying the rights to the content, operate openly with contact details that can be verified and provide support to the customer. The prices of unauthorized services are usually extremely low, the number of channels is often excessively high (5,000 or more), and the legal framework is unverifiable. It is the responsibility of the users to make sure that their IPTV provider is properly licensed in their location.
The technology has become a reality, practical, and very common. The first step towards its responsible use is to understand.
