18.6.1 ON DEMAND OR LIVE STREAMING?
Not all 'streaming' is 'live streaming.' The difference is similar to i) watching a
television program you previously recorded at a time convenient for you, or ii)
watching a live event.
On demand streams are stored on a server (often supplied by an external service
provider), ready to be transmitted whenever a viewer wishes. Live streams are
available at the time they are broadcast, such as during a live concert or event.

TriCaster permits you to record live productions to a local hard drive. The resulting
files can be hosted on a network later, so viewers can connect whenever they like. If
you have the resources available, you can host the video yourself – but if many people
will likely want to view your production, you will likely avail yourself of a service to
stream it on your behalf.
Ideally, 'on demand' streaming video begins to play on request after a few moments.
(Letting the stream get a bit ahead of the client playback device is called 'buffering',
and helps ensure smooth playback). This stands in contrast to other types of online
video distribution which requires the viewer to completely download the video file
before he can begin play. Given a sufficiently high speed connection between host
and viewer, they may well be able to enjoy a seamless viewing experience without
stuttering or other issues.

TREAMING
Live streaming is a growing international market, and one you may well wish to serve.
This form of streaming is a somewhat more demanding implementation. Rather than
record a file and deal with it later, live video is transmitted over the network
(effectively in realtime, give or take a little 'time in the pipe' as it were.)
Delivering a good quality stream requires that you consider both your network
connection capabilities and that of your viewers. As well, to ensure reliable delivery,
you will ideally have some idea of the size of your audience. Nevertheless, for all
cases, TriCaster gives you the tools to do the job.

Questions and answers
Can the switcher have a background still with PPT slides over top rightside of frame, and then have live camera feed on left?
Yes, the NewTek TriCaster Mini can display a background still with PowerPoint slides on the right side of the frame and a live camera feed on the left. It supports compositing live and video-on-demand inputs, including PowerPoint slides from a connected computer. The system allows for chroma key operations and mixing multiple video sources, enabling such a layout.

my tricaster only has one KEY option and two DSK options and 4 Mix Effect options. is there a way to add more of these items into my tricaster layout?
The TriCaster Mini includes Key layers in M/Es, which function similarly to Downstream Key (DSK) layers but are embedded upstream in the Mix Effect (M/E) output. However, the provided context does not mention the ability to add more KEY, DSK, or Mix Effect options beyond what is already available in the system.

Thank you for answering my question. There is a buzz on the output of our Tricaster410. Not sure why this is happening now.
A possible cause of a buzz or distortion on the output of a NewTek TriCaster Mini could be incorrect audio gain settings in the Output Configuration. Specifically, the gain controls for STREAM 1 and STREAM 2 may need to be adjusted. Setting the gain to -20 can eliminate distortion and align the output level with the TriCaster MASTER.
