Introduction(HDTV)

• High Definition Television offers the consumer
  unprecedented broadcast picture quality and
  digital surround sound
• Six times better than the current standard
  broadcast resoultion
• HDTV 1920 1080 6 SDTV 720 480
• Bandwidth of Uncompressed HDTV
• 1920 1080 resolution
• 24-bit pixels
• 8-bit Red, Green and Blue values
• 30 progressive frame per second
• Bandwidth 1920 1080 24 30 1.49Gbps
• Using MPEG2 HD(1280 720 60fps) comppressed by
  20Mbps

Introduction(IEEE1394)

• high-speed serial bus alternatively known as
  FireWire and i.Link
• A hardware and software standard for transporting
  data 100, 200, 400 or 800 megabits per
  second(Mbps)
• Inexpensive and Easy-to-Use
• Hot pluggable
• Non-proprietary

Audio/Video Digital Interface of Choice
