Scalable video transcoding converts bits from a network data stream into a picture for the user and conversely translates camera video into a bit stream to transmit across the network. It breaks up video bit streams into bit stream subsets that add layers of quality and resolution to video signals. This maximizes quality at any bandwidth and resolution.
The benefits to scalable video transcoding include:
- Improved streaming quality.
- Reduced bandwidth and resource usage.
- Accessibility on both computers and mobile devices.
How Transcoding Works
Transcoding occurs entirely in the cloud and does not require additional institutional resources. Scalable video transcoding lowers operational costs and requirements. It also eliminates bandwidth bottlenecks, limiting long loading times, and provides viewers with a high quality user experience on a computer or mobile device.
YuJa automates the transcoding process. When you upload video content to the Media Library, the content is processed and transcoded; once the transcoding is completed, the content is available through the Media Library and can be posted to the Public, Campus or Course Channels. The same transcoding process occurs for YuJa-created content, like lecture captures recorded with the Software Station or Hardware Hub.
The User Experience
Users are not aware of the scalable transcoding process. For the user, the video is simply available, streaming smoothly over various connections and systems. While the adaptive bitrate streaming integrated into the scalable video transcoder automatically chooses the best video resolution, users can choose to override that in the YuJa Media Player to select a lower streaming rate.
