Video over IP & IPTV

IPTV 101 for Universities, Technical Colleges and E-Learning

From hosting your own e-learning content to providing entertainment for students, IPTV is an extremely versatile technology that has numerous benefits for universities, technical colleges, and other educational organizations.

Over the last decade, universities around the world have embraced IPTV technology as a way to deliver educational content to students using a more flexible, scalable platform than typical classrooms and lecture theaters.

If you’re involved in managing an educational organization, IPTV should be at the top of your tech-related priority list. Below, we’ve explained how universities and other institutes of higher education can use IPTV to deliver better service and better results for their students.

Create e-learning programs for remote study

One of the biggest advantages of IPTV is that it allows your organization to create its very own e-learning platform.

E-learning, or online learning, lets your students participate in lessons and view lectures using their computer or mobile device, all without having to physically visit the classroom to take part in a lesson.

This means students can participate in your class on their own schedule, eliminating scheduling conflicts that are common for busy students. It can also ease the strain on your classrooms for popular classes that result in overcrowding.

Because e-learning content can be streamed or viewed later in the day, your students can also rewatch lectures and lessons to catch up on missed classes or refresh their memory before an exam or assessment.

If your school has multiple campuses, e-learning content delivered using IPTV can also help you create a “bridge” between locations, saving your students from commuting between campuses just to participate in one class.

The end result is a higher quality, more convenient experience for your students that also help you offer a wider range of classes without scheduling or overcrowding problems, with the help of HDMI wireless video technology.

Provide entertaining content in dorms and residences

Living on campus should be a fun, fulfilling experience for students. One of the easiest ways to make on-campus life more fun for residents is to use IPTV to provide on-demand entertainment in dorm rooms and on-campus residences.

IPTV can be used to provide on-demand entertainment, with the latest television shows, movies and other content available for students and employees at any time.

Instead of relying on regular TV to access engaging content, students can tune in to your own campus IPTV channels or access entertainment on demand. This is an easy, effective way to make your school or university more appealing to students considering on-campus living.

On-demand entertainment can also be a great source of revenue for your school. By paying to access content, your students can contribute money for important things like facility repairs and maintenance, community events and more.

Deliver important messages and announcements

IPTV also makes it easy to deliver announcements across your entire campus. Instead of using a traditional announcement system, your campus staff can use IPTV to deliver audio and video messages to hundreds of classrooms, offices and public areas at once.

This makes IPTV a great tool for alerting students and staff to safety issues on campus, events that are ongoing or soon to begin, changes to normal scheduling and other issues that students and staff members should be aware of.

Schools and universities can also use IPTV in emergencies to deliver important information on a mass scale.

Since IPTV scales extremely well, using it as a public announcement platform can cost far less than traditional technology, helping your campus deliver important information faster at a lower cost than the alternatives

Understanding The Most Common Video Encoding Formats

When you watch a video online, rarely are you viewing the original footage. Online video, either streamed or downloaded, is encoded one of several video codecs as a way of reducing the file size and making transfer a faster, easier and less taxing process for hardware.

If you’re interested in live streaming or video production, knowing more about the most popular and widely used video encoding formats can help you deliver high-quality footage without the usual large file sizes or quality issues that can be a major problem online.

Below, we’ve listed the four most common online video formats, along with a brief description of each codec’s key advantages, disadvantages, and unique features.

MPEG-4

Widely used online, MPEG-4 is one of the most common video formats available. MPEG-4 type encoding can be used to store both audio and video — most of the time, you’ll see it used as an option for video, with the file extension .mp4.

MP4 stands for “MPEG-4 Part 14.” As one of the oldest video containers out there, MPEG-4 has been widely used since the late 1990s. Because of its low file size, it’s a popular option for a video that needs to be downloaded before viewing, as well as online streaming video.

As well as its small file size, a key advantage of MPEG-4 is its compatibility. Almost every device and browser, from modern PCs and smartphones to aging hardware, will offer complete support for MP4 video.

AVI

AVI, or “audio video interleave,” is another old video file format. Developed in the early 1990s as a Windows video codec by Microsoft, AVI is one of the most widely viewed digital video options, with an almost defacto status for web video.

One interesting fact about AVI video is that it can be encoded using a variety of different video codecs. This means that while AVI itself is widely compatible, you might need to download an additional codec if you’re viewing an AVI video on an older computer.

Like MPEG-4, AVI is so widely used that it’s viewable on almost any device. Most short, lower resolution online videos are saved in the AVI format, although you’ll also find many short videos saved as MP4 files.

H.264

Another highly versatile video codec, H.264 has grown massively in popularity over the past few years as video content on the web has switched from lower resolutions to full HD and, in the last two to three years, to 4K.

A major advantage of H.264 is that it’s extremely versatile. Videos encoded using H.264 can be lossy and small in size, or almost completely lossless. It’s also far more efficient, from a file size perspective than older video codecs such as MPEG-4.

If you want to minimize your video’s file size while preserving as much detail as possible, H.264 is a great option. It’s also a widely supported codec, with full support on almost every operating system for PCs and mobile devices.

H.265

High-Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2, is a video compression standard, one of the several potential successors to the widely used AVC (H.264 or MPEG-4 Part 10). In comparison to AVC, HEVC offers double the data compression ratio at the same level of video quality or substantially improved video quality at the same bit rate. It supports resolutions up to 8192×4320, including 8K UHD.

In most ways, HEVC is an extension of the concepts in H.264/MPEG-4 AVC. Both work by comparing different parts of a frame of video to find areas that are redundant, both within a single frame as well as subsequent frames. These redundant areas are then replaced with a short description instead of the original pixels. The primary changes for HEVC include the expansion of the pattern comparison and difference-coding areas from 16×16 pixel to sizes up to 64×64, improved variable-block-size segmentation, improved “intra” prediction within the same picture, improved motion vector prediction and motion region merging, improved motion compensation filtering, and an additional filtering step called sample-adaptive offset filtering. Effective use of these improvements requires much more signal processing capability for compressing the video but has less impact on the amount of computation needed for decompression.

MOV

If you’re an Apple user, you’ll definitely recognize this file format. Introduced by Apple as part of QuickTime in the 1990s, MOV is a video format that’s widely used to compress video produced using Mac OS.

Apple has updated the MOV file format over the years, with the current QuickTime X offering a good mix of quality and compression. Because this format is designed by Apple for its range of devices and operating systems, it isn’t as widely used as AVI or MPEG-4.

Another reason for the lack of popularity of MOV files is their lack of compression. While most MOV files are of a reasonable file size, they still take up more space than equivalent video in AVI, MP4 or H.264 formats.

4 Advantages of Wireless HD Video

Over the last few years, a growing number of broadcasters and video recording companies have been switching from traditional copper cables and fiber optics to wireless recording gear.

The reason? Well, there are several. From improved mobility to excellent quality, wireless video technology offers a range of advantages that have made it so appealing to camera operators in a wide range of different settings.

With the increasing affordability of wireless HD video, we’re also seeing a range of smaller video producers make the switch and go wireless. Below, we’ve shared four reasons for the growth of wireless video, from its increasing affordability to range, quality, mobility and more.

Impressive transmission distances

Not long ago, most live video experts associated wireless video with short signal distances and interference problems. Today, wireless HD video equipment is capable of transmitting a strong, reliable signal across an impressive distance to a receiver.

For example, the Wireless VidOlink Ranger is capable of transmitting broadcast grade MPEG 4 COFDM HD footage across a range of up to two miles, as long as there’s a direct line of sight in between the transmitter and receiver.

Even affordable wireless video equipment is capable of transmitting high-quality footage across a reasonable range. Our VidOlink 5G Low-Cost Wireless HD-SDI Link, for example, boasts an impressive 500-meter range when used with optional high gain antennas.

The days of short signal distances and continual interference are over. Today, wireless video equipment can provide a very usable range that’s useful for a wide variety of event settings.

Video quality

Some modern wireless video equipment supports resolutions of up to 1080p, as well as great frame rates of 60 frames per second or more. This makes it easy to shoot and transmit clear, crisp footage using wireless recording and transmission equipment.

Better yet, many wireless units allow for the transfer of completely uncompressed footage, all with no noticeable latency. This means that wireless gear can be used to transmit broadcast quality footage suitable for standard television and IPTV.

Just like the signal distance of wireless gear has been improving over time, many of today’s top wireless video transmitters offer comparable quality to wired fiber optic, making the “low quality” debate a non-issue.

Improved mobility

One of the biggest advantages of wireless video is its mobility. Instead of having to step over cables or worry about expensive fiber optic cables catching on chairs, tables, and other items, wireless video transmitting allows camera operators to focus on getting the perfect shot.

In a live event environment, this means that camera operators can get closer to the action and capture more engaging, impressive footage. It also lets camera operators move at a far faster pace to capture events as they happen and keep viewers engaged.

At the end of the day, it’s great footage that matters most. The incredible portability of IPTV video networking makes it easier for camera operators to get the shots they need for a detailed, engaging and effective production.

Affordability

Like many other technologies, wireless video equipment has gotten more affordable in the last decade, allowing small businesses and organizations that could previously never afford it to add it to their video production equipment collection.

We offer a range of affordable wireless video products, with our VidOlink 5G Low-Cost Wireless HD-SDI Links designed to fit into every live video production budget. Today, there’s no need for a Hollywood-level budget to add wireless video to your technology toolkit.

What Is The Maximum Range For Wireless Video?

When you’ve got to shoot a live event, even the shortest, smallest cables can be a major source of annoyance. From tripping and falling to catching on tables, seating, and other items, cabling is an irritating necessity of live video that offers just as many downsides as it does advantages.

Add in the fact that cables limit the range of your camera operators and it becomes clear why so many live video companies are looking for alternatives.

Luckily, there’s a great solution out there. Modern wireless video equipment allows you to record live events with ease, all without having to worry about loose cables catching on items or posing a safety risk.

Like all technologies, a wireless video has advantages and disadvantages. It’s convenient, highly portable and surprisingly affordable. However, it does have one downside: many wireless video systems just don’t have the same range as fiber optic video cable.

In this post, we’ll look at the different ranges for wireless video equipment and explain what your options are as a video producer. We’ll also share specific recommendations for equipment that’s designed for long range transmission without a noticeable decline in picture quality.

What is the maximum range for wireless video?

There’s no single maximum range for wireless video equipment. Instead, different equipment is designed to allow for a different maximum transmission distance, with our systems ranging from as little as 10 meters all the way up to two miles.

The distance that wireless video can travel depends on several factors. The first of these is the type of antenna that’s used. A small, low-gain antenna is unlikely to be able to transmit video at an acceptable level of quality for a long distance, whereas a high-gain antenna likely can.

Most of the time, you’ll see a direct correlation between price and transmission distance. Some of our low-cost wireless transmitters, such as the VidOlink Ranger Wireless HD-SDI Link, have a maximum range of up to 3000 feet for HD SDI and HDMI signals.

Add high-gain antennas and this range can increase to 1500 feet, showing the difference that higher quality, more sensitive antennas can make.

Another option is to use a line of sight transmission equipment. This type of equipment has a high transmission distance and little to no latency or interference, largely because it’s designed for a point to point, a line of sight transmission.

As you’d expect, a line of sight equipment only provides good performance when there’s nothing in the way of the devices effect the transfer. Some line of sight video transmission gear, such as the Wireless VidOlink Ranger, has a range of up to two miles.

Lose the line of sight and this equipment will still perform, albeit with a far lower range than the amount you can expect with a direct line of sight between the two devices.

What can affect a wireless video transmission?

Wireless Video

A variety of factors can affect the quality of a wireless video. In a live event setting, physical items and objects such as people, plants, and buildings can affect the quality of a wireless signal, with a noticeable decline in the range of a wireless video transmitter system.

The best way to avoid this is to make sure there’s always an uninterrupted line of sight between your video transmitter and receiver. Another option is to use wireless ethernet links in areas that contain lots of people, trees, structures and other sources of interference.

Another factor that can affect the quality of your video transmission is the weather. Heavy rain and lightning can negatively affect most video transmission equipment, making it hard to provide a clear signal on rainy or turbulent days.

A Guide to IPTV for Churches and Houses of Worship

For churches and houses of worship, IPTV can be a great way to expand your reach and deliver your message to people using a convenient platform.

Designed to help broadcasters deliver their content online, IPTV uses the internet to broadcast video. Just like a traditional television channel, viewers can tune in to watch your content using their computer, smart TV or mobile device.

Where IPTV differs is in its convenience, cost, and scalability. Since viewers can watch from their tablet or mobile device, consuming your content is easier and more convenient than ever, with a large range of remote viewing possibilities.

IPTV is also massively scalable. Since your content is broadcast over the internet instead of via traditional television infrastructure, you can reach a huge number of people at a small fraction of the usual cost.

These advantages make IPTV a great option for churches and houses of worship that want to reach more people at an affordable, manageable cost.

If you’re interested in using IPTV for your church or house of worship, you can read more about our range of IPTV equipment and services. Below, we’ve also listed some of the key advantages of IPTV for churches to help you make an informed, effective decision.

Increase your reach beyond your community

One of the biggest benefits of IPTV for churches and other houses of worship is that it lets you expand your reach far beyond your local community. Instead of having to visit your church for a service, people can tune in from any location to listen to your message and take part.

Because IPTV technology uses the internet to broadcast your service, people from any location can tune in online. There’s no geographical limit on your message — instead, you can reach an audience in any country and time zone.

For small churches, this is a great way to expand your audience without having to expand your premises. If your church is often over-crowded, IPTV can be a way to offer a more comfortable method of attending service for your followers.

The larger your reach, the more powerful your impact. With IPTV technology, you can expand your audience beyond the physical confines of your building, letting you reach more people in your local area and around the world.

Broadcast your message at an affordable cost

Traditionally, broadcasting your religious content was an expensive process. Most broadcasters used either local or national television services, both of which require a significant investment in equipment, infrastructure, and staff.

Because IPTV operates over the internet and uses scalable digital infrastructure, it costs far less to reach a large audience using IPTV technology than it does to operate a typical TV channel for your house of worship.

IPTV equipment also costs far less than traditional TV broadcasting equipment. In fact, many of the world’s top IPTV broadcasters transmit their content at an extremely low cost — a fraction of the amount spent on traditional television.

Create an archive of your services

Finally, one of the biggest benefits of using IPTV technology to broadcast your services is that you can create a complete, lasting archive of your services as you conduct them.

Because IPTV download content is always available, viewers can tune into your services at any time in any location. After you stream your content, you can make it available online for users to watch at any time in the future.

This makes it easy for new followers to familiarize themselves with your services. It also means that your long-time followers can tune into services they previously attended online to listen to your message again or catch up on things they missed in person.

Get started with IPTV

We specialize in IPTV and have helped a large range of houses of worship use IPTV to reach a larger audience and provide a wider variety of service options to their followers.
