Streamio uses video players that comply to
What is accessibility?
Accessibility is about making content accessible to all users, regardless of disability. For video and audio, this may be to provide subtitles, visual recognition, text version (transcription) and sign language.
Accessibility for all users is a human rights issue – the UN Convention on the Rights of Persons with Disabilities is the basis for the regulation of the Web Directive.
The web should be available!
In the video above you can experiment with our available texts yourself, click on the “CC” icon in the top right of the player.
First, you get to choose your language, if you want to make further adjustments, click settings.
There you can change the color, size, background, and more.
All so that video uploaded to Streamio is accessible to everyone!
Not only the public sector needs to be accessible
Accessibility adaptation is not an issue that only concerns public actors, even if the Web Directive is targeted at them and not private actors. Lack of accessibility is a problem in many ways:
On the one hand, all companies that supply municipalities, county councils, government agencies and authorities are affected. But also private companies that need to make their content accessible to everyone.
Lack of accessibility can result in the exclusion of part of the market in which one operates, especially people with disabilities. Some accessibility aspects are important even for a wider audience. For example, subtitles are important to increase accessibility in the following cases:
- A person may not know the language completely fluently and wants the support of both listening and reading.
- Or subtitles are used when watching a movie in an environment where it is not possible to have adequate volume on the film.
- A third option is that the sound of the film at times is bad, or some actors talk unclear.
Better searchability, SEO
Another advantage of improving its availability is its positive effect on search engine optimization, or SEO.
Providing subtitles and transcriptions for movies and audio files, such as podcasts, helps recipients, but they also help search engines understand your content. It is thus a great way to be found when someone searches for content you touch.
Subtitles and transcriptions
Streamio supports WebVTT subtitles that work for both mobiles and computers. We also offer automatic conversion of SRT files and editing can be done directly in Streamio.
With us, Subtitles work with languages that have different character sets to work for all languages. In Streamio’s video player, it is possible to display a transcription window next to the player with the entire content of the movie as text. Streamio’s video player supports WebVTT styles for custom text appearance.
In our video player, there is built-in support for keyboard navigation, which the organization Web Accessibility in Mind believes is the single most important feature for increasing accessibility on the web.
The video player is adapted to support the WCAG AAA contrast level and allows you to customize this to your own needs in case of tailored CSS.
The video player is tested against screen readers and the following are recommended:
- NVDA 2017+ with latest Chrome on Windows 10+
- VoiceOver with latest Safari on macOS 10.12+
- TalkBack with latest Chrome for Android
- VoiceOver with latest Safari on iOS 12+
Development of accessibility at Streamio
We are constantly working to ensure that Streamio has the highest possible availability. Right now, these are our priority areas for development in accessible video.
Tests are underway to integrate automatic captioning and transcription, we aim to release this functionality in 2021. This would make it possible to include subtitles on all videos on Streamio.
Multiple audio tracks
For efficient handling of audio description, we investigate the technical conditions for several audio tracks (which can also be used for several languages, for example).
Multiple video tracks
For character interpretation, we look at different solutions and have not yet chosen the path. Transparent video overlays are a way to go, or multiple synced players. We are also looking at implementing several video tracks that you can switch between which would be a flexible and reliable solution.
The market's most affordable video platform
Try Streamio you too and move resources to the budget of video production instead of distribution!
Not a big decision. You can test as long as you want, all features, free of charge (and without credit cards!)
Ways to make video available
Separate sign language version
The most common thing is to produce two films, one without sign language and one with an image-mixed variant where the character language is included. Image-wise, it is important that the face and hands are clearly displayed, and that it maintains a high quality of streaming as well as the resolution (HD quality!) is important. SVT is an actor that creates a separate sign language version for character interpretation in production. An alternative to doing this directly in production is to create an overlay that the media server can turn on and off, or to create a layer in the media player, which can also be turned on and off.
Another way is to provide a video player that can switch between multiple channels, where the user can choose the version of the movie. In this case, two films are produced, one with and the other without sign language – these are then delivered as tracks for the user to choose from.
Another option is to work with multiple movies that are synced. This usually produces two windows, one with the film and one with the character interpreter. Having synced movies makes it difficult to function in different receiving devices, such as mobiles.
