Data Rate Display
The data rate display shows the current data rate of of the encoder over the past 60 seconds.
The data rate is measured in megabits per second. This indicator runs consistently, even when
off air, so you can accurately gauge your bandwidth before going on air.
Cache Display
The cache display shows the percentage of your Web Presenter's built in memory buffer that is
currently in use and the graph shows the amount used over the past 60 seconds. The cache is
a small amount of internal memory that continuously records and plays the program output.
It acts as a safety measure if the streaming data rate decreases below a level able to
sustain video.
The variable nature of the internet is mostly due to network activity or wireless signal strength,
so if the broadcast data rate decreases, the buffer data will increase accordingly. If the
connection speed becomes slow enough that it cannot support the video stream, the cache will
fill with video frames to compensate. However, once the cache is 100% full, the video stream
will be compromised, so you will want to avoid a full cache where possible. You can run a test
by connecting a video feed and watching the cache display in the monitor output without
having to start the stream. If the cache frequently approaches 100%, choose a lower quality in
the live stream settings.
Audio Meters
You can monitor the levels of your audio source using the audio meters. These can be set to
display either PPM or VU levels in the Web Presenter's menu settings. If your audio levels are
too high the meters will illuminate red and may mean that the audio in your live stream could
become distorted or clipped. Ideally try to keep your audio towards the top of the green section
and occasionally in to the yellow section.
