IEEE 1394/firewire a low cost, high speed, digital serial bus

摘要

Does the world need yet another 1/0 bus standard. If you need fast and cheap serial video communication, then the answer is yes. As technology advances, so too must data transport mechanisms advance. You can't expect RS- 232 to support real-time digital video, and if you can't afford expensive professional serial video interfaces, (such as Sony's Serial Digital Interface), Firewire may be a good solution. IEEE 1394, or commonly known as Firewire, is a general purpose serial bus that meets many of the 1/0 needs of today's video and multimedia developers. For those of you who only read the first paragraph, here's Firewire in a nutshell: It provides a guaranteed transfer rate of 10OMbps or 20OMbps of digital data (such as video direct from camera to computer), over an inexpensive, non-proprietary serial bus. Here is a list of its features.
