5 Image Data Formats and
Structures
5.1 Image Data Basics
Image data is transmitted as isochronous data packets according to the “1394 - based Digital
Camera Specification” (DCAM) issued by the 1394 Trade Association (see the trade association’s
web site: www.1394ta.org). The first packet of each frame is identified by a 1 in the sync bit of the
packet header.
5.1.1 Pixel Transmission Sequence
Pixel data is transmitted from the camera in the following sequence on the A102f:
Row 0/Pixel 0, Row 0/Pixel 1, Row 0/Pixel 2 ... Row 0/Pixel 1390, Row 0/Pixel 1391
Row 1/Pixel 0, Row 1/Pixel 1, Row 1/Pixel 2 ... Row 1/Pixel 1390, Row 1/Pixel 1391
Row 2/Pixel 0, Row 2/Pixel 1, Row 2/Pixel 2 ... Row 2/Pixel 1390, Row 2/Pixel 1391

Row 1037/Pixel 0, Row 1037/Pixel 1, Row 1037/Pixel 2 ... Row 1037/ Pixel 1390, Row 1037/Pixel 1391
Row 1038/Pixel 0, Row 1038/Pixel 1, Row 1038/Pixel 2 ... Row 1038/ Pixel 1390, Row 1038/Pixel 1391
Row 1039/Pixel 0, Row 1039/Pixel 1, Row 1039/Pixel 2 ... Row 1039/ Pixel 1390, Row 1039/Pixel 1391
Pixel data is transmitted from the camera in the following sequence on the A102fc:
Row 0/Pixel 0, Row 0/Pixel 1, Row 0/Pixel 2 ... Row 0/Pixel 1386, Row 0/Pixel 1387
Row 1/Pixel 0, Row 1/Pixel 1, Row 1/Pixel 2 ... Row 1/Pixel 1386, Row 1/Pixel 1387
Row 2/Pixel 0, Row 2/Pixel 1, Row 2/Pixel 2 ... Row 2/Pixel 1386, Row 2/Pixel 1387

Row 1035/Pixel 0, Row 1035/Pixel 1, Row 1035/Pixel 2 ... Row 1035/ Pixel 1386, Row 1035/Pixel 1387
Row 1036/Pixel 0, Row 1036/Pixel 1, Row 1036/Pixel 2 ... Row 1036/ Pixel 1386, Row 1036/Pixel 1387
Row 1037/Pixel 0, Row 1037/Pixel 1, Row 1037/Pixel 2 ... Row 1037/ Pixel 1386, Row 1037/Pixel 1387
(These sequences assume that the camera is set for full resolution.)
