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.

| Matrox Meteor-II /1394 has three IEEE 1394 input ports to |
Inputs |
| 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. |
