Bitrate, as the name implies, describes the rate at which bits are transferred from one location to another. In other words, it measures how much data is transmitted in a given amount of time. Bitrate is commonly measured in bits per second (bps), kilobits per second (Kbps), or megabits per second (Mbps). For example, a DSL connection may be able to download data at 768 kbps, while a Firewire 800 connection can transfer data up to 800 Mbps.

Bitrate can also describe the quality of an audio or video file. For example, an MP3 audio file that is compressed at 192 Kbps will have a greater dynamic range and may sound slightly more clear than the same audio file compressed at 128 Kbps. This is because more bits are used to represent the audio data for each second of playback. Similarly, a video file that is compressed at 3000 Kbps will look better than the same file compressed at 1000 Kbps. Just like the quality of an image is measured in resolution, the quality of an audio or video file is…

Internet Society Community Grant: Summary

Today, online presentation applications are increasing in popularity and providing powerful tools for creation of instructional materials and accessible information in audio-visual formats.

Auto-play: A usability and accessibility failure

My organisation recently published a number of videos on the public website (EDIT – have removed the link as the videos have been taken off now). Those videos started automatically as soon as the page loaded. The problems with this are:

Automatically playing audio on a webpage is usually an action which the user will not expect. It is therefore, at the very least, an irritation, especially if the user is in an environment where this is not appropriate.

At worst, though, the audio may conflict with other audio that the user is already listening to. That might be music, or perhaps another video. But far worse, it could be a blind user’s screen reader software, and the resulting conflict would make it very hard to browse that page to pause the video or mute the sound.

PresentationTube Project Startup in Oman

Many barriers are facing the selection and development of quality e-content in developing countries, particularly in the Arab region. Many of these barriers could be avoided through rapid e-learning development networks that easily encourage educators to create and share quality e-content themselves. Research highlighted the importance of considering the potential possibilities that online videos present when deciding how to support recent e-learning communities. Watching video is considered as a basis for mental activity. It is socially acceptable and widely used and supported by multimedia cell phones and portable media players. Video can add interest and engagement to e-Learning and training strategy deliveries. PresentationTube, a non-profit and research-based project, and one of the winners of the Internet Society Community Grant 2013, offers a video presentation recorder and video sharing network to help teachers and learners in Oman produce and share quality video…
