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
website: 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 A601f and A602f:
Row 0/Pixel 0, Row 0/Pixel 1, Row 0/Pixel 2 ... Row 0/Pixel 654, Row 0/Pixel 655
Row 1/Pixel 0, Row 1/Pixel 1, Row 1/Pixel 2 ... Row 1/Pixel 654, Row 1/Pixel 655
Row 2/Pixel 0, Row 2/Pixel 1, Row 2/Pixel 2 ... Row 2/Pixel 654, Row 2/Pixel 655

Row 488/Pixel 0, Row 488/Pixel 1, Row 488/Pixel 2 ... Row 488/ Pixel 654, Row 488/Pixel 655
Row 489/Pixel 0, Row 489/Pixel 1, Row 489/Pixel 2 ... Row 489/ Pixel 654, Row 489/Pixel 655
Row 490/Pixel 0, Row 490/Pixel 1, Row 490/Pixel 2 ... Row 490/ Pixel 654, Row 490/Pixel 655
Pixel data is transmitted from the camera in the following sequence on the A601fc and A602fc:
Row 0/Pixel 0, Row 0/Pixel 1, Row 0/Pixel 2 ... Row 0/Pixel 654, Row 0/Pixel 655
Row 1/Pixel 0, Row 1/Pixel 1, Row 1/Pixel 2 ... Row 1/Pixel 654, Row 1/Pixel 655
Row 2/Pixel 0, Row 2/Pixel 1, Row 2/Pixel 2 ... Row 2/Pixel 654, Row 2/Pixel 655
