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 is transmitted from the camera in the following sequence:
Row 0/Pixel 0, Row 0/Pixel 1, Row 0/Pixel 2 ... Row 0/Pixel 1278, Row 0/Pixel 1279.
Row 1/Pixel 0, Row 1/Pixel 1, Row 1/Pixel 2 ... Row 1/Pixel 1278, Row 1/Pixel 1279.
Row 2/Pixel 0, Row 2/Pixel 1, Row 2/Pixel 2 ... Row 2/Pixel 1278, Row 2/Pixel 1279.
