Knob Icon. The knob icon appears adjacent to items on the display to indicate
that the rotary knob controls that item. For example, when the knob icon appears
next to a menu (as shown in Figure 2-3), you can use the knob to move through
the menu items. When the knob icon appears in a dialog box adjacent to a
highlighted parameter value, you can use the knob to adjust that value.

Figure 2Ć4: Status bar
The Status bar shows the following information:
1. Standard. This indicator displays the standard of the selected stream.
(MPEG2, ARIB, DVB, ATSC, S-TMCC, M-TMCC, or Non TS).
2. Loop Mode. This indicator displays which loop mode is being used for the
stream output (No Update, Auto Update, or Stress). Refer to Output Loop
Modes on page 2-15 for more information.
3. Packet Size. This indicator displays the packet length in bytes (188, 204,
208, or Non TS) of the stream output.
4. Clock Source. This indicator displays the source of the reference clock
(internal or external) used for the stream output.
5. Bit Rate. This indicator displays the bit-rate (in Mbps) of the stream output.
6. Position. This indicator displays the status of the stream output using time
and a duration gauge. The time indicates the stream time elapsed since the
beginning of the stream. The value is reset every time after the stream file
generation is complete. The duration gauge shows the progress of stream
generation.
The duration gauge is updated every 1 second. If you output the stream with
repetition rate of 3 seconds, the gauge may not be displayed correctly.
7. Output Status. This indicator displays the current status (Running or
Stopped) of the stream output.
