Foil 24 Navigation and random access

From MultiMedia Databases - Collaboration, Recording and Playback ASC Dayton OH Web Training Meeting organized by CSU -- 6 May 98. by Geoffrey Fox, Marek Podgorny
1 Current version: video or audio stream drives slideshow
  • Control: play, stop, rewind - but no random seek
    • Reason: uses HTTP protocol for continuous media stream
    • to facilitate random access, video segmentation is necessary (can be labor intensive; tools may be provided)
    • We do this segmentation for Real Audio now
2 Target version: two-way navigation with random access
  • unless video stream edited/segmented, needs video server support for random stream access
    • Reason: needs random access protocol such as RTSP
