3History
VHS won out even though Betamax was better quality
4VHS vs. BetamaxWhy VHS won
- Licensing problems between Sony and other
companies - VHS initially simpler and cheaper to produce
- Beta initially had shorter recording times
- VHS won out in rental market
5Why do we need a new format?
6DVDs
- Single Layer 4.7 GB
- Only enough for a few hours of standard
definition content - Not good for High Definition content which is
much bigger - Dual Layer still only 8.5 GB (Not nearly enough
for HD content)
7New Formats (HD-DVD and Blu-Ray)
- MUCH bigger
- HD-DVD single layer15 GB
- Blu-Ray single layer 23-25 GB
8What about dual layer?
HD-DVD Blu-Ray
Single Layer 15 GB 23/25 GB
Dual Layer 30 GB 46.6/50 GB
RW Single Layer ---- 23.3/25/27 GB
RW Dual Layer ---- 46.6/50/54 GB
Highest Test 45 GB 100 GB
Theoretical Limit 60 GB 200 GB
