Foil 14 Digital Video: Network Delivery Options

From Video Server,Delivery and Compression Technologies SC95 Tutorial on Web Technologies -- December 4,95. by NPAC Team * See also color IMAGE
Most of the digital video frameworks are local mass storage (CD-ROM, hard disk) oriented. So is standard Web video technology (download first, then play). Telco's and CATV technology is mostly not IP-based. Interactive TV standards (DAVID - Digital Audio/Video Interactive Decoder) seem orthogonal to Web technology at present and will not be discussed in this tutorial.
Network delivery options: shared file access and audio/video servers
  • Shared file access: NFS, Samba (NetBios (SMB) servers for Unix) , AppleShare, LAN Manager .......
    • disadvantages: not really continuous media protocols, some slow (NFS, AppleShare), no development path for QOS support, security problems, do not fit Web model although may be useful when used internally on LANs.
  • "middle of the road" solutions like NetWare Video.
  • Audio/video servers: custom servers providing real time continuous media streams.
    • Examples: RealAudio Internet audio server, Oracle's Media Server, Xing's StreamWorks, Intel's/CNN CNN at Work, NPAC video server
