AV1394(4D) Devices AV1394(4D)

NAME

av1394 - 1394 audio/video driver

SYNOPSIS

unit@GUID

DESCRIPTION

The av1394 driver implements iec61883(4I) interfaces for IEEE 1394
compliant devices.

Asynchronous Transactions

The driver allows applications to act as FCP controllers, but not FCP
targets. Only IEC61883_FCP_CMD requests can be sent with write(2).
Only IEC61883_FCP_RESP requests can be received with read(2).

Isochronous Transactions

When the read/write method of is used for transmit, the driver is
capable of auto-detecting and transmitting SD-DVCR 525/60 and 625/50
streams. See iec61883(4I) for details.
