Presentation complexity screen
One of the strengths of Repeat Signage is the flexibility to design
presentations exactly as you want them without the use of restrictive
templates or limitations on certain types of controls. However,
different controls use different amounts of processor time and memory.
For example, the h video control playing an HD video will cause a high
usage of a computer's processor and memory resources. A few
video controls playing videos is fine. However, if you have 16
video controls playing in the same presentation the computer's resources
will be severally stretched and may possibly lead to the system stalling or
crashing.
Presentation complexity index
The presentation complexity index is a number generated by
analysing the controls used in your presentation. We are recommending
an index value of 50 or below. We calculate this by giving a number to
different controls a complexity number and also whether they using playlists
or scrolling and/or monitoring. For example the video control
has an index of 5. So if you have 10 of these playing at the same time
then that gives 50 which will result in the processor working very hard.
A Picture control has an index of 1, if using a playlist then 3 and if
scrolling 6. If files are monitored for changes then they get an extra
1 added to their total.
Summary counts
Complexity index - See above.
Controls - Total number of controls in your presentation.
These include:
RSS control
Clock (round) control
Controls using playlists - The total number of controls that are
using the playlist feature. This may be either PLAYLIST, DAILY, HOURLY
or WEEKLY that allow scheduling of different content at different times.
Controls that use these are slightly more complex as Repeat Signage has to
monitor the system time and load new content as necessary. Where you
have straight playlists in use that may swap an image, say every 5 seconds,
then these can use more system resources to do this and are therefore more
complex.
Controls using scrolling - Controls which scroll. For
example, you can scroll a serials of pictures across the screen. These
controls take a lot more system resources that controls that are static.
Controls using monitoring - If you use a picture control, for
example, you can choose to monitor this picture and if it is updated the
Repeat Signage automatically loads and displays it. This takes more
system resources to monitor and change items.
Warning messages - Specific messages about this presentation and
advice.
What to do if you have a presentation index over 50
Here are some things to look for to reduce the complexity of your
presentation:
1. Look at the amount of text controls that use scrolling. Look
at each scrolling control in turn and ask yourself "Does it really need to
scroll?". If the answer it no the stop it scrolling and just display
the text.
2. Look at the amount of picture controls that use scrolling.
Look at each scrolling control in turn and ask yourself "Does it really need
to scroll?". If the answer it no then stop it scrolling. If the
answer is yes, then also consider using animated gifs or video files
that would give the same effect.
3. Look at video controls you are using. First consider
converting to video controls as these are more efficient. Next,
if you have more than one, consider using just one larger video control and
use a playlist to display videos one after another instead.
4. Could any of the controls be combined into less controls. For
example, text labels next to each other can sometimes be combined into a
single text label or text block control.
5. If you have clip art images next to each piece of text, consider
removing them.
6. If you have more than one banner control, consider just
having one larger one and combining the playlists of each.
7. If you have more than 5 things moving on screen, ask yourself if
this is really necessary. Take a look at your presentation from a
couple of metres away from the screen. Are you getting your message
across to your audience or have you just created a screen full of moving
things?
