IPTV encoders and decoders play an important role in the process of distributing video content to viewers. If your business depends on IPTV, high quality encoders and set top decoders are a valuable investment that will help you stream and view content online.
In this guide, we’ll explain how IPTV encoders and decoders work. We’ll also share information on how encoders and decoders fit into the process of streaming video content. In addition, we’ll explain why it’s important to invest in high quality encoders and decoders for your business.
How IPTV Works
Instead of being limited by a predetermined schedule, IPTV allows viewers to decide what they want to watch, when they want to watch it. Television “on demand,” which most consumers are now familiar with, is an aspect of what’s possible using IPTV technology.
Behind the scenes, IPTV depends on both software and hardware devices. From the equipment used to film live streaming content to encoding equipment, communications equipment, set top decoding equipment and more, a surprising number of devices are involved in any IPTV stream.
The IPTV Process
Distributing IPTV content requires several devices. First, there’s the video source. For content that’s already been recorded, the video source could be a video file, a DVD or Blu-Ray disc, a reel of film or any other medium that can record and store video.
For live content, the video source is typically a camera. Since so many devices contain cameras today, the camera itself could be integrated into a smartphone or tablet, or it could be a high-end or professional video camera, DSLR or mirrorless still/video camera, or even a tiny action cam.
Video recorded by a camera is typically uncompressed and unprocessed, resulting in a gigantic file size that makes distributing the video over the Internet unfeasible.
This is where an IPTV encoder enters the picture. An IPTV encoder takes the content from the video source, whether it’s a live recording from a camera or an uncompressed video file from a digital storage device, and encodes it for distribution over the Internet.
Video encoding involves converting the video file into a format that web browsers, smartphones and other devices support. It also often involves compressing the video to a more manageable file size and quality level, which lowers strain on the hardware and improves transfer speed.
Once a video is encoded, it’s usually stored on a web server, from which viewers can tune in and access the video.
Finally, the IPTV decoder’s role is to receive the content and decode it into a format that your television or other digital device can play.
IPTV decoders prevent piracy and unauthorized viewing of content. Since the video content is encoded, viewers need to have a compatible decoder in order to decode the content and watch it using their computer or television.
For IPTV on a television, the most common type of decoder is a “set top box” — a small device that connects to your display and decodes the video content. Like most IPTV devices, set top boxes can range from inexpensive consumer units to high-end decoders for enterprises.
What IPTV equipment do you need?
As a business, your IPTV equipment needs will ultimately depend on how you plan to use IPTV to distribute content. Enterprises with multiple offices and locations, for example, have different needs from hotels that need to distribute content to hundreds of rooms, suites and displays.
The key to effective IPTV is to understand your needs and work with an expert to determine the best encoding and decoding hardware to help you achieve your objectives.

For businesses of all sizes, communication is key. Being able to clearly communicate with your employees, executives and contractors can give your business a measurable edge in response time and its ability to quickly execute on new projects.
From email to in-person meetings and conferences, enterprises rely on a variety of methods of communication. One increasingly popular and important communications channel is enterprise IPTV — internet-based video.
Enterprise IPTV has several benefits for businesses. It’s fast, affordable and easy for a business in any industry to implement. It can also be a valuable communications tool for speaking directly to your team or communicating with customers.
Below, we’ve listed five benefits of enterprise IPTV for businesses in a variety of industries, from professional services to hospitality, manufacturing and more.
IPTV uses your existing network
One of the biggest advantages of IPTV is that it uses your existing network instead of requiring a new one. As such, there’s no need for new cabling or large amounts of hardware to be set up throughout your building.
IPTV distributes content using an IP-based network, meaning there’s no need for cabling, media satellite dishes or other communications hardware.
If you want to use IPTV within a single building, it’s easy to set it up using your existing ethernet technology. For companies with multiple locations, IPTV integrates easily with your existing web server, allowing people in remote locations to easily access content online.
It’s compatible with a large range of devices
Unlike physical media, such as DVDs or solid state storage, which often can specific hardware to operate, IPTV is easy to watch using any display technology. You can stream IPTV content to a smart TV, a computer display, a smart device and a wide range of other devices.
This makes IPTV a great option for enterprise businesses with employees in an office setting, in manufacturing plants and work sites, and in the field. Instead of depending on specific hardware to view content, you can easily broadcast important content to almost any device.
IPTV scales easily, with no viewing point limit
Because IPTV uses an IP distribution network, there’s no limit on the number of people that can watch your content at once. This makes it easy to enterprise IPTV to broadcast announcements and other business-related content to your entire workforce at once.
From conferences to training exercises, this lack of limitations makes IPTV highly effective for businesses that thrive on communication. For example, you can broadcast an announcement about a new policy, product or service to your entire team at once, instead of doing so locally.
IPTV gives viewers more control than ever before
Traditional broadcast TV limits what viewers can and can’t do. If someone misses an important detail and wants to backtrack to find it, they might not be able to do so. If a viewer wants to go back and rewatch certain content, they might need to wait until the next broadcast.
IPTV, on the other hand, gives viewers almost total control over how they watch content. In case someone misses an important detail, they can “rewind” and watch it again. If a team member is absent and needs to watch content after other people, they can easily do so at their own speed.
IPTV is extremely cost effective
From the low costs of enterprise IPTV hardware to the improvement in productivity IPTV makes possible, the overall cost of IPTV is extremely low. In fact, for most businesses, IPTV creates a significant positive return on investment in improved productivity, efficiency and output.
Instead of buying hardware specifically for the purpose of watching video, IPTV gives your staff the power to watch video from any internet-enabled device. Lean, efficient and effective, IPTV is a cost effective communications channel from which any enterprise business can benefit.

Here is a list of 17 mistakes or necessary questions to ask your current or potential In-house IPTV and Enterprise IPTV provider.
1. No support for distribution to desktop, laptop, smartphone and tablet
A typical RF coaxial television system is only going to allow for the distribution of specific displays and tvs. Do you need to access video content over the corporate wide area network at the desktop, laptop, smartphone, tablet, set-top box, Smart TV, TVs, and Displays? If yes, VidOvation TV is the right choices. The way users function and interact in the corporate setting is rapidly changing. We are not bound to the displays in our offices, break rooms, hallways, lobbies, etc. We need to access our corporate content right at our fingertips on ANY device. This is an absolute necessity for your enterprise content delivery network.
2. Getting stuck with one content provider (CATV/SAT) or without open architecture
The biggest down-side to working directly with a content provider is their tendency to control the content allowed on your network. Even if you were able to switch, the hardware and software provided by them will “miraculously” be incompatible with everything others content. You will want to ensure that you can pick and choose the content for your network as you like as well as implement open architecture equipment as to keep your options open all the time. This is important for cases in which, say one provider raises rates, you can have the ability to switch to another vendor. Also, it allows you to mix and match the content from multiple different satellite and cable providers.
3. No support for Digital Rights Management or DRM.
In the case of DirecTV and Dish Network, they use encryption called Pro:Idiom and it can be quite problematic. DirecTV and Dish Network will not turn off encryption unless you have an approved DRM system or digital rights management system. You want to make sure you ask your IPTV vendor, “Do you have an approved DRM system approved by DirecTV and Dish Network?” There’s a very short list. Our solution happens to be on that list. You need to ask those questions. We’ve had clients try to go it on their own. “Well, I’ll put my own IPTV system together,” and what happens is you’ll be stuck with standard definition. You won’t be able to get high definition or the system just won’t work at all. This is what you need to ask your vendor to make sure that they have the capability to help you with all these different hurdles that may come up.
4. Not allowing integration of your own VOD content with your providers
A great enterprise video networking system has the capacity for the storage and dissemination of corporate content to employees. Stored video can be relevant information, updates or training for employees. An example of this may be a corporation-wide HR video that must be watched by everyone by the end of the day. With your own content distribution, an activity that cost a large amount of time and money can now be accomplished very efficiently within the hour.
5. Not allowing for Your Own Live Video Distribution
Live content distribution can be incredibly valuable in the enterprise world. Today’s businesses are expected to respond quickly to news, changes, and emergencies, and this is the best way to do it. The ability for an executive to reach his entire team instantly in regardless of location is priceless.
6. Insufficient or Non-Existent Video Conferencing Functions
Whether you are in separate offices, abroad, or connecting to potential clients across the globe, the video conferencing functions of enterprise video networking are often undermined by potential providers. Whether you are picturing top level conferences or live video networking and collaboration among employees, make sure you aren’t missing out on this important piece of the picture.
7. Lacking Scalability, Security, and Flexibility
Choosing a scalable and flexible system is the only way to ensure your investment has longevity. You may want to add more channels and more viewers to your system at a future date. Additionally, you want to have the capacity for selective user upgrades without changing out set top boxes.
8. Non-Friendly User Interface
Designers get too crazy. The best GUI (graphical user interface) is a familiar user interface. You don’t want to get stuck with a video system on your corporate network that everyone hates. We prefer to use an intuitive design for the menu with a CSS (cascading style sheet) editable format enabling simple customization and tailoring to your enterprise. Make sure you can easily brand and customize your IPTV system.
9. Creating Hell for IT Administrators
For IT Administrators, it’s always about keeping trouble off the network, and video, using large amounts of bandwidth, is perceived as trouble. It is important to ensure that you have a sophisticated design that can allow for video to have the smallest impact possible on your networks bandwidth.
10. Limited User Authentication Options and Weak Traceability Features
Top executives may need access to critical corporate information and everything below while entry-level employees may only need some training materials. You may have your unique set of administrative rules allowing access to a particular network and television assets. Furthermore, being able to trace a particular person’s usage or viewership is something you may desire. For example, in the case of important content, you will want to be sure that everyone has watched an important video. VidOvation TV systems tie into the corporate network active directory to control all video access and authentication options.
11. No Integration with Digital Signage
Digital Signage is prevalent in every industry. Depending on your application, you may want to run breaking news, welcome information, live event coverage or advertisements to the lobbies, hallways, break rooms, etc.
12. No Integration with Property Management System
When there’s no one around, let your enterprise video networking system stay on security watch. Allow your security team live and recording access to your facilities security cameras and let them be able to access it from any of their devices.
13. No Personal Recording Functions
We take enough notes on paper. In many cases, this is not the ideal format to record something. With personal recording functions built into your enterprise video network, you can record video clips for personal storage.
14. Foregoing High Definition Video Quality
With the increasing demand of HD video quality, there’s no doubt you will want this as an option. With the right implementation, you should be able to upgrade from standard definition as needed and do so with minimal disruption to network bandwidth.
15. Lack of Customization
Hospitals may seek extra features to play in telemedicine applications. Hotels may desire the help desk messaging features. Military implementations may include 16 streams simultaneous playback functionality. Universities may want advanced solutions for their classroom e-learning applications.
16. No integration with Catering and Food Services
You’re in your VIP suite, and you have an on-screen menu. We have done integration with some venues where this page is more of a template, with an XML file that pushes the menu items there, and then you can click on an item. Depending upon your needs, if you just want a simple electronic menu that you can edit and update that displays on a food channel or a food ordering channel at the venue, that’s very simple to do. We can do some custom programming and integrate an interface with Aramark or your food service provider at your venues. We can work on customizations for you. Ask your vendor, “Can you do some professional services to integrate catering and food services into the IPTV system?”
17. Lack of Low Latency and Synchronous Video
In sports venues, some owners and facility managers have been very upset by this where displays that are in proximity to a live sporting event are way out of sync or delayed. There are many systems out there that have a second of delay or hundreds of milliseconds of delay between displays, and then seconds of delay between the action on the field and the live action on the IPTV system. VidOvation customized the firmware on the Amino set-top box to guarantee synchronous video and a minimal delay between the live action and the IPTV system.

Error correction techniques for IP networks (Part 7 – Hybrid FEC + ARQ vs. 10 x 10 ProMPEG Cop3 FEC)
Hybrid FEC + ARQ vs. 10 x 10 ProMPEG Cop3 FEC performance
The 10 x 10 ProMPEG Cop3 FEC used in the example above has a theoretical error correction performance of 20%. The FEC matrix shape enables packet recovery of 10 consecutive lost IP packets and 10 random lost IP packets provided the lost distribution is one single IP packet per row.
The example above (the Matrix on the left) shows a situation where 15 consecutive IP packets are lost. The FEC can only recover loss of 10 consecutive IP packets and the ARQ must recover the remaining 5 IP packets.
In a TCP (Transmission Control Protocol) friendly environment the accumulated bandwidth (bit-rate) must be kept reasonably constant. In this example, the accumulated transmission bit rate is kept constant by changing the FEC overhead to 10% and to use this bandwidth for the ARQ system to re-transmit the IP packets the FEC could not recover.
The bandwidth limitation for the ARQ system also limits the error correction capability of the ARQ to how many IP packets can be recovered. In the actual example the ARQ is restricted to re-transmit up to 10 IP packets per FEC matrix (100 packets).
Hybrid FEC + ARQ can therefore recover a loss of 20 consecutive IP packets plus a number of random losses of single IP packets. This is an improvement of 100% over a standard 10 x 10 ProMPEG Cop 3 FEC with regards to burst packet loss.
The same size ProMPEG Cop3 FEC with a 20 x 5 Matrix shape and 20% overhead can also recover a loss of 20 consecutive IP packets, but it’s capability to recover random loss of single IP packets is less efficient than a 10 x 10 shaped FEC matrix.
In most cases a service bandwidth is limited by the service provider, which limits the error correction capability for the service regardless of the technology. In other words, the error correction capability of the above mentioned methods are very much the same especially if the channel bandwidth is limited. If the bandwidth is “un-limited” or at least two times the channel bandwidth all the above technologies can correct for very high IP packet loss rates.
The typical overhead is normally kept between 10% and 30% in practical implementations, yielding very similar error correcting capability of the example mentioned above.
