Data Results
A Data Result message adheres to the general structure for result messages as defined in the Result
Format section (page 113).
A Data Result contains a variable number of blocks depending on the sources selected for Ethernet
output. Each selected source contributes two data blocks (and accompanying data block descriptors):
one block for attributes and one block for content such as video pixels or measurement results.
