the correct view and player can be selected (e.g. duration of the media, the format and coding and whether it is
video or audio) are FFmpeg [24], YouTube API and a link to the file itself.
3.2 Captions
Captions can be displayed on a desktop browser with the video but there appear to be no standards for
displaying captions within web pages across all tablets and mobiles alongside transcriptions and annotations. At
present if someone is deaf they have to read the caption and watch the video and then scroll down to the notetaking
mode. It is not possible on the iPhone to display both the transcript window and the video due to the size of
the screen. However, it will be possible to capture an image from the video and annotate this as part of the note
taking process.
3.3.Synote Mobile requirements
• SCREEN SIZE ISSUES: work on mobile phone screens as well as tablets so should automatically detect the
device and load the corresponding page or style sheet.
• DELIVERY OF THE VIDEOS: adaptive i.e. devices with low resolution and bandwidth need to download
smaller file sizes. The player will take over the full screen when playing, so a thumbnail picture will be
displayed alongside the transcript and annotations.
• FORMAT COMPATIBILITY: Different devices and browsers have different support mechanisms for HTML
video codecs [25] so delivery of multimedia resources has to be adaptable.
