Live Broadcast Software for Teaching Online Classes

Are you using video as an online educator? If not, you should be. As one recent article stated, “Video is becoming as ubiquitous in classrooms as laminated periodic tables and whiteboards.” This article aims to support educators getting started with OTT video by providing a review of live broadcast software.

Specifically, we’re going to look at some of the top live broadcast software on the market today. We’ll also review the difference between software and hardware for live streaming, and when you want to use one solution over the other. Before we get to those reviews, we’ll first go over some basics about why and how educators are using online video.

About two-thirds of teachers agree that video education helps students learn. This article aims to help provide you with the tools you need to grow that number even higher.

Video is a powerful educational tool

Video is an unmatched tool for communication. As the saying goes, a picture is worth a thousand words. In that case, a video made up of 30 pictures per second is worth 30,000 words per second of video. That may sound like hyperbole, but it’s simply true that video is a more natural means of communication for human beings than text is. The face-to-face element is key.

This is reflected in the data. According to one review of the scientific research, the benefits of using online video for education include:

  • “enhance[d] comprehension and retention of information”
  • Support for “multi-modal” learning
  • Appeal to multiple learning preferences
  • Help students understand complex information
  • Develop digital literacies

How educators are using online video

Live Broadcast Software for Teaching Online ClassesEducators are using online video and live streaming in a wide variety of creative ways. One example is the increasingly-popular “flipped classroom” model. In this approach, lectures are live streamed or available via on-demand video. Classroom time is reserved for questions, discussion, and examples.

This approach makes the most of limited teacher resources and allows students to study and learn at their own pace. The same approach can be very valuable for non-native language speakers. They may need to play back videos at a slower speed, or watch sections over and over. Video facilitates this.

Video is also great when students have to miss class for important reasons. The ability to stay up with work enables students to stay up to date. This can be essential for students who have children, work a job, or experience family emergencies.

Finally, video is ideal for distance learning. Distance learning is becoming an ever-larger part of education around the world—and with good reason. Video makes this all possible. Whatever you’re using video for, remember that the way that you use it should be targeted based on your specific learning goals.

5 top live broadcast software

One of the essential elements in successful live broadcasting is called an “encoder.” An encoder takes the video feed from a camera, such as a webcam or external video camera, and transcodes it into a format that’s suitable for live streaming.

Typically, this format is called RTMP. Most encoders are RTMP compatible. Streaming platforms typically transcode into a format like HLS.

There are two main types of encoders that are available today. The first is software encoders, or what we can call live broadcast software. These applications are installed on a computer or mobile device.

The second type of encoder is called a hardware encoder. These are dedicated, single-purpose devices that accept camera inputs. They do the same job as a software encoder, but in a different way. Hardware encoders come in all shapes and sizes. Some are small, portable, and designed to be attached to your camera for streaming using cell networks. Others are large, rack-mounted units for studio use.

Our list will include both live broadcast software and hardware encoders.
