Adding Jitter to PCRs (MTG300 Only)
The MTG300 MPEG generator provides the capability to add jitter to PCRs
(Program Clock References). Adding jitter to PCRs allows you to simulate
transmission delay variations and to test the robustness of decoders under
various conditions.
The MPEG generator provides two types of jitter functions: Interval Jitter and
Value Jitter. Refer to Interval Jitter Function on page 3-90 and to Value Jitter
Function on page 3-92 for detailed information about the two jitter functions.
Adding Jitter
Perform the following procedure to add jitter to PCRs:
1. Use the Icon cursor to select the PCR item in the hierarchy display that you
want to replace. If the Icon cursor is not displayed, press the MENU button
to enable the Icon cursor.
2. Press the Stress PCR... bezel button. This opens the PCR Stress dialog box
shown in Figure 3-31.
