Figure 3.15 Input Detection Configuration
Operation
If no source is connected or the input source is not recognized then Not Detected is
reported as the detected video standard, a video lock alarm is raised and the output
on video loss setting will apply.
If the VCM can lock to the new input, a change in the input format the detected
standard will be displayed and the selected configuration file for the detected format
is applied.
Note: ONLY the video, audio, VANC and VBI configuration parameters from the
stored configuration for the associated options card are applied in this case.
All other cards and base unit parameters remain unaffected.
If the video is embedded in a Transport Stream for which Bit Rate Tracking Mode is
set to Maximize Video, and the Bit Rate Weighting for the video component is set to
other than Fixed or Minimal, then the Video Bit Rate might also get updated. For
more information, see Operation and Control > Bit Rate Tracking. Some examples
are also given below:
•
Source changed from HD to SD , and Profile for SD input is set to SD MPEG-2
Main Profile Main Level 4:2:0 8 bit: The new encoding profile is SD MPEG-2
Main Profile Main Level 4:2:0 8 bit. The bit rate is limited to 15 Mbps (maximum
allowed by profile) if it was higher than 15 Mbps before the change. Otherwise
the bit rate is not affected.
