Ethernet and 1394 Coexistence

Use, Data/Best Effort

Highway or Railroad
• Ethernet/802.3 CDMA is like a highway
– Traffic affects access, time of arrival, no guarantees
– If it “Absolutely Positively” must be there on time,
you ship it ahead of schedule, and warehouse it.
• TDMA/TDD is like a railroad
– Reserve space, known speed, guaranteed time of
arrival
– Just in time delivery “When it Absolutely Positively
Has To Get There”

Why Not Wait for Ethernet
Solution?
• Most Profits for CE are in HD Products
• Digital Transition
– DTVs must have Tuners (MPEG decoders)

– Analog shut down in 2008/2009
• Complex solutions require time to stabilize
• Start simple
– Solve today’s problems today
