Videoload is a Video-on-Demand service of the Telekom Deutschland GmbH that enables users to watch movies and TV-shows on desktop devices, smartphones, smart-TVs and set-top-boxes. Fraunhofer FOKUS has developed the HTML5 video player that handles the playback on desktop and mobile devices. Our solution supports different adaptive streaming formats (MPEG-DASH and HLS) and utilizes native browser extensions (MSE and EME) to enable playback in all browsers without the need for third party plugins like Flash or Silverlight. The player is designed in a responsive manner in order to adapt to different screen resolutions and provide an optimal user experience on different platforms.
