  3. Introduction • The IEEE 1394 interface is a serial bus interface standard for high-speed communications and isochronous real-time data transfer • Frequently used by personal computers, as well as in digital audio, digital video, automotive, and aeronautics applications. • The interface is also known by the brand names of FireWire (Apple), i.LINK (Sony), and Lynx (Texas Instruments). • IEEE 1394 is the High-Definition Audio-Video Network Alliance (HANA) standard connection interface for A/V (audio/visual) component communication and control. • FireWire is also available in wireless, fiber optic, and coaxial versions using the isochronous protocols. • A self-configuring network

  4. History & Development • It was initiated by Apple (in 1986) and developed by the IEEE P1394 • Working Group was largely driven by contributions from Apple, although major contributions were also made by engineers from Texas Instruments, Sony, Digital Equipment Corporation, IBM, and INMOS/SGS Thomson (now STMicroelectronics). • Apple intended FireWire to be a serial replacement for the parallel SCSI bus while providing connectivity for digital audio and video equipment.

  5. Working Data exchange between FireWire cameras and computers

  6. Types of Connectors • FireWire 400 (IEEE 1394-1995) • It can transfer data between devices at 100, 200, or 400 Mbit/s half-duplex • These different transfer modes are commonly referred to as S100, S200, and S400. • Cable length is limited to 4.5 metres (14.8 ft), although up to 16 cables can be connected using active repeaters; external hubs, or internal hubs • FireWire 800 (IEEE 1394b-2002) • This specification and corresponding products allow a transfer rate of 786.432 Mbit/s full-duplex • A bilingual cable allows the connection of older devices to the newer port. • Apple was the first to introduce commercial products with this new connector.

  7. Types of Connectors(contd.) • FireWire S1600 and S3200 • In December 2007, the 1394 Trade Association announced that products would be available before the end of 2008 using the S1600 and S3200 modes that. • The 1.6 Gbit/s and 3.2 Gbit/s devices use the same 9-circuit beta connectors as the existing FireWire 800 and will be fully compatible with existing S400 and S800 devices. • Future enhancements (including P1394d) • A project named IEEE P1394d was formed by the IEEE on March 9, 2009 to add single mode fiber as an additional transport medium to FireWire. • Other future iterations of FireWire are expected to bring a bump in speed to 6.4 Gbit/s and additional connectors such as the small multimedia interface.

  8. USB vs. FireWire • The Transfer rates of the USB and FireWire are as follows: • USB 1.1: Transfer limit of around 11Mbps (1.5MB per second) • USB 2.0: 480Mbps (60MB per second) • USB 3.0: 4.8Gbps (Yet to be released) • FireWire 400 (IEEE 1394a): 400 Mbit/s data rates (50MB per second) • FireWire 800 (IEEE 1394b): 800 Mbit/s data rates (100MB per second) • FireWire S1600: 1.6Gbps • FireWire S3200: 3.2Gbps • FireWire uses simpler bus networking, provides more power over the chain and more reliable data transfer, and is less taxing on a CPU. • USB requires the presence of a bus master, typically a PC, whereas FireWire is a true peer-to-peer network. Thus allowing either device to serve as the host or the slave.

  9. Common Misconception • 1394/FireWire usage is declining • Over 1 Billion 1394 Ports have shipped to date • • Deployed in Over 600 Million devices worldwide • • 1394 is Projected To Grow by 20 percent in 2008 • and into 2010 in: • – Digital set top boxes • – Digital televisions • – PC peripherals • – DVD-equipped PCs • – Non-PC optical disc drives • – DVD aftermarket kits • Who needs FireWire? Ethernet is fine for entertainment • • Ethernet is asynchronous • – No guaranteed QoS

  10. Common Misconception(contd.) • – No system-wide clock for synchronization • – High network overhead reduces realized throughput • as more devices/traffic added • • Less secure • – Security is typically software based, not built into the • Hardware • USB 2.0 is just as good as FireWire • Test Results For Storage Transfer Rates • – USB 2.0: 30 Mbytes/sec • – S400: 42 Mbytes/sec • – S800: 90 Mbytes/sec • –S3200: 362 Mbytes/sec • • Real World Results for USB 2.0 are even slower • than indicated

  11. Common Misconception(contd.) • HDMI is the entertainment connection of choice • HDMI Is Not A Network • • HDMI is a Point to Point, local connection • – It is Not Routable • – It is Not Symmetrical (low-speed back • channel for control only) • • Recording is prohibited • • It is an end point for a network. There is no • approved networkable output for HDMI.

  12. Application • Consumer Products • • DTVs/HDTVs • • DVD/Blu-ray Players/Recorders • • Digital VHS Recorders • • Digital Video Cameras • • Digital Cameras • • MP3 Players • • CD Players/Recorders • • Digital Video Recorders (DVRs) • • Personal Video Recorders • (PVRs) • • HD Cable Set Top Boxes • • Media Center PCs • • Audio/Video Receivers • • Digital Video Editing • • Digital Video Production • • Digital Projectors • • Digital Audio Recording

  13. Application(contd.) • The Computer Products Market • • Displays and Monitors • • Desktop Computers • • Laptop and Tablet • Computers • • Workstations • • Hard Disk Storage • • CD-R/RW& DVD-R/RW Drives • • Digital Video Editing • • Printers • • Scanners • • WebCams • • Host Adapter Kits • • Motherboards • • Media Card • Readers/Writers • • Software Development Tools • • Cables

  14. Application(contd.) • Automotive and Aerospace • • Fujitsu: In-vehicle multimedia networks controller ICs • supporting IDB-1394 at 100/200/400 Mbps • • 1394 TA Automotive WG: IDB-1394 over Copper • Specification for Vehicle Multimedia Networks – Due • Q2, 2008 • •The US F-35 Joint Strike Fighter includes 70 • on-board 1394 devices for communication • systems, weapon systems, engine controls, • and flight controls.

  15. Conclusion FireWire is one of the fastest peripherals ever developed, which makes it great for use with multimedia peripherals such as digital video cameras and other high speed devices like the latest hard disk drives and printers. It provides an inexpensive, high speed method of interconnecting digital devices. FireWire800 doubles the throughput of the original technology dramatically increases the maximum distance of FireWire connections, and supports many new types of cabling. The FireWire roadmap outlined is assumed to take upto a staggering rate of 3200Mbps from the theoretical 1660Mbps.that is 3.2 gigabits per second that will make the FireWire indispensable for transferring massive data files and for even the most demanding video applications, such as working with uncompressed high definition video or multiple standard definition video streams.
