In the HG and XG images, the DDC & DUC derive their sense of time from the header of passing packets. This sense of time is necessary to execute timed commands. Repeatedly issuing timed commands without streaming will result in the command queue of the DDC / DUC backing up and overflowing, putting the device in a state where a full restart is required. + + */ // vim:ft=doxygen: |
