When the Flywheel Video Decoder is turned on, a caution will appear
as shown in
Figure 39 on page 71 . Since the Flywheel decoder generates
its own video timing for the incoming video stream to deal with noise
and interruptions, leaving it on during normal operation may cause
undesirable re synchronization delays if the source changes or is lost. It
will take about 9 seconds to change states.
• Frame Reference –
• 2000GEN frame reference signal presence reported,
• Enable/disable Loss of Signal report to both Kameleon status pages
and SNMP monitoring devices.
• SDI Input Errors – displayed only for SDI input (SDI or Auto)
• ‘Input signal errors reported.
• Enable/disable SDI error warning report to both Kameleon status
pages and SNMP monitoring devices.
• Frame Sync/Delay – (read-only) Frame Sync mode is reported when
Output Timing Selection is
Internal Frame Reference and timing is pro-
vided from the 2000GEN module. Delay mode is reported when the
input signal (
Video In ) is used for timing reference
Output Timing Selection
If you have a 2000GEN reference module installed in the frame and want
the Kameleon to work as a frame synchronizer, set the output timing source
to
Internal Frame Reference . Otherwise, set the output timing source to Video In .
Note For correct composite out color framing in PAL-B, always use the Internal
Frame Reference.
Note When a video input with embedded audio is switched, the audio will mute
when the module is set to Delay mode (Video In reference). To avoid any
audio muting, use the Internal Frame reference (Frame Sync).
