Isochronous I/O for IEEE 1394 Devices
Real-time multimedia devices such as digital cameras need large amounts of bandwidth to send data in a steady stream, but do not require guaranteed delivery. (For example, a dropped frame from a digital camera would degrade the quality of the signal, but it would not destroy its meaning.) For such devices, IEEE 1394 provides isochronous transfer, which provides guaranteed bandwidth, but does not guarantee delivery.
