• But it has not been possible for mass
consumers
Video On Demand
Unicast Approach
Not for Broadcasters
VOD

• Not scalable
• Only possible for small scale services
• i.e., Hotel VOD

Content Encoding
• Encoding
– Higher compression MPEG4
• Saves storage & transmission cost
– Near DVD quality at much lower bit rate
• 700K – 1.5M bit/sec
• CIF resolution
– Off-line or On-line encoding
• Off-line: multi-pass, VBR encoding for highest possible
visual quality
• On-line: single pass, CBR encoding for real time streaming
– ISO Standard
• Multiple suppliers
• Philips, Envivio, iVast, DiVX…etc
Hotel Video Distribution
Content Reception
• Small footprint 19’ rack
– VHF/UHF Antenna or Satellite dish
