Matrox Meteor-II /1394
Matrox Meteor-II /1394 is capable of acting as bus manager
(cycle master), isochronous resource manager, and node
controller ("root"). The cycle master triggers the data signal at
125-microsecond intervals. The isochronous resource manager
is responsible for reserving, distributing, and managing the two
modes of data streams (isochronous and asynchronous) along
the available bandwidth. The root controller can control all
peripheral devices connected (up to a maximum of 62).
The 1394 bus transfers real-time (isochronous) data streams
through a four-layered architecture, two of which are
implemented in hardware: the Physical Layer and the Link
Layer.
Inputs Matrox Meteor-II /1394 has three IEEE 1394 input ports to
which 1394 devices can be attached, as long as the configuration
of devices complies with the IEEE 1394 tree topology. Serial
data bus rates of 100, 200, or 400 Mbits per second are shared
across the three ports. MIL-Lite can be used to grab from
monochrome or color digital cameras that are compliant with
the IEEE 1394 Digital Camera Specification (DCS). Note that
YUV 4:2:2 data is grabbed in UYVY format.
