A streaming media and video terms glossary that contains definitions of acronyms, technologies and techniques. The definitions are related to live streaming, broadcasting and video hosting.
These video terms are relevant for both new techniques and legacy methods, which still have ramifications today when handling older media. There is a larger emphasis for online video applications, although a few terms which have roots in older methodology and processes. The glossary will be continuously updated as the industry evolves. Links to learn more and for relevant articles will be added overtime as well. If you are looking more for some tips on executing these terms, check out these 5 Pro Tips for Video Production.

Notre Dame’s Eric Nisly guides live-streaming of commencement and other events using resources like this production truck.
Live-streamed video takes you to the heart of an event and lets you share in its emotion from wherever you are.
Maybe a friend or family member is crossing the stage to get a diploma, or an ensemble of musicians is playing passionately to win a prestigious international prize, or a university is interviewing teachers and students during an online fundraiser to share with alumni the kind of moments that make the campus special.
These are just some of the hundreds of annual events now streamed by the University of Notre Dame. The volume of streamed events has roughly doubled in the last three years as the public’s appetite for streaming video grows.
Notre Dame’s production team, including Streaming Engineer Eric Nisly, have learned from experience a few best practices that make a big difference in keeping glitches low, emotional impact high, and results solid. We asked Eric to share 9 of his top tips.
- Get the word out
- Plan to fail
- Keep crew responsibilities narrow
- Get the two most wanted camera angles
- Ensure live support from your streaming platform
- Better than selling DVDs: stream goodwill
- Document success: crowdsource your streaming playbook
- Build strategic vendor relationships
- Keep raising the bar: put a point person on R&D
Live-streamed video, enabled by a cloud-based video platform, is having a big impact on the business world. That’s the conclusion of a new enterprise video guide.
One example of video’s impact, the guide notes, was at an 8,000-person financial company with dozens of sites around the world. The company faced a sudden marketplace change, and its CEO asked employees to watch a live all-hands meeting over secured, streaming video. The executive described the company’s new strategy in the meeting, and employees got their questions answered through the video platform’s Q&A module in real time. The company pivoted in an hour, leading its field.
Another example of impact is when a global car maker used live streaming video to draw 3,400 unique viewers to a new model introduction at an auto show. The company was able to reach beyond the 300 press members in the room.
A year later, at the same auto show, the car maker streamed another model introduction and this time it included LiveAd, a service of IBM Cloud Video. LiveAd displays streaming video in standard ad units on strategic sites. Users roll-over the ad to make the video bigger, without having to leave the site. A click makes the stream play full screen.
Video streaming and delivery is a resource intensive process. This is attributed to the various networks a video stream must pass through as well as the quality of the video, as higher bitrates and resolutions require more information related to that stream to be sent to the end viewer. As a result of this requirement, it’s not recommended to broadcast video using your own server. For companies, this can result in bottlenecks from the servers hosting or unnecessary costs to scale a server infrastructure.
One solution to avoid both, though, is through utilizing a CDN (content delivery network). This piece talks about the basics of delivering content over the Internet before why it’s important to have a CDN when streaming video content.
If you are already familiar with CDNs and would rather learn more about how Ustream offers a more robust solution for video streaming, read our live video scalability white paper.

Looking for a white label video player solution? Broadcasters can spend hundreds if not thousands on their setups, from top of the line cameras to hardware encoders that can allow for camera switching, only to have the end product touting another company’s brand which can cheapen the viewer experience.
IBM Cloud Video offers a wealth of features to help customize and allow content owners to control a viewer’s experience. This is presented as part of a white label video platform, allowing the removal of the IBM Cloud Video branding and also allowing content owners to insert their own. This article covers these features in more depth. It looks at where and how content owners can remove IBM Cloud Video branding and insert their own and also how content access can be restricted. This includes insight into how content owners can manage elements of the video player, embedding, viewer access, and also the channel page experience.
If you would prefer to see these features demonstrated over video, feel free to watch our on-demand Streaming Manager Demo.
Have you ever seen video content that looks like the image above, but weren’t sure of the cause? These overt horizontal lines, appearing as pixelation around movement like out of an old school Atari game, are an artifact created from presenting an interlaced source in a progressive format.
This article explains what is interlaced video content and which sources, such as analogue cameras, can produce this type of video content on live streams. It then goes over deinterlacing techniques to remove this artifact and how to easily enable it on the encoder side… and why you wouldn’t want to use deinterlacing on content that is already progressive. If you, however, are familiar with deinterlacing and are looking to upgrade your equipment to avoid this issue instead, please reference our Video Studio Recommendations white paper.
The default mental image of video compression involves unwanted video artifacts, like pixelation and blockiness in the image. This sells short, though, the complexity that actually goes into compressing video content. In particular, it overlooks a fascinating process called interframe, which involves keyframes and delta frames to intelligently compress content in a manner that is intended to go unnoticed.
This article describes this process in detail, while also giving best practices and ideal encoder settings that you can apply to your live streaming at IBM Cloud Video. Much of this specific advice relates to streaming due to adaptive bitrates. To learn more about that technology, reference our How Adaptive Streaming Solves Viewer Bandwidth Issues white paper.
Video is everywhere, and by 2017 80% of all the world data will be video. It feels like the world suddenly discovered live streaming, which is something we’ve been doing here at Ustream since 2007. In fact, don’t tell Periscope or Meercat, but live streaming on mobile devices isn’t even new. We introduced our first broadcast-capable apps for iOS and Android all the way back in 2009 (really!) and since then we’ve helped Fortune 500 companies launch new products, broadcast concerts from famous recording artists, help citizen journalists document events, and family members share special moment via live, on-the-scenes broadcasts.
Now don’t get us wrong … we’re very happy that live streaming is getting a lot of buzz and that everyone decided to join the party. We’d like to take a step back and show you a brief history of streaming video and how we got to where we are now!
No matter what size your company is, it’s a no brainer that integrating live and recorded video into your communication strategy is the key to success. But where do you start? Luckily our technical Sales Engineer, Adam Pastana, is here to save the day and will walk you through getting started with Ustream, and cover the basics on how to quickly get up and running with the Ustream platform.
