MTG100 & MTG300 MPEG Generator User Manual
The MPEG generator provides two replacement modes in the Replace Setup
dialog box for replacing the selected section data: Section End and Timing. This
subsection describes the differences between these two modes.
Section End Replacement Mode. In the Section End replacement mode (see
Figure 3-27), data replacement starts when the following conditions occur:
H The time set in the Start Time parameter of the Replace Setup dialog box
arrives
H The packet with payload_unit_start_indicator value 0x0001 is detected
After the time set in the Continuous Time parameter of the Replace Setup dialog
box arrives, data replacement is ended.
