The info-beamer hosted package running at 33c3
For 33c3 I've developed a new approach to scheduling and layout. Last year's version uses a mostly fixed layout of scroller, main content and an optional sidebar. This version is more flexible: Basically you can define tiles with changing sizes that show the various content modules available. Hiding a scroller can for example easily be done by moving the scroller tile out of the screen and resizing the main content tile. All content is scheduled with a fixed duration. Multiple devices using the same schedule will show the same tiles at the same time. But this also means that it is not possible to have content of variable duration. So the schedule is pretty rigid.
While everything is packaged as an
package and the twitter, frab and scroller sub nodes
can be easily configured from the hosted interface,
the main schedule configuration is a bit clunky.
For that reason there's a configuration tools in
config subdirectory which uses a custom
file format to make it easier to schedule content.
In the future a way to configure such packages from within the info-beamer hosted configuration interface will be developed. Stay tuned...
The package can easily be installed within hosted by clicking this button:
Alternatively you can manually import the package from

area definitions you can create named areas.
These areas can then be used in the schedule definition to
move content around.
Scheduling is done by adding multiple lines. Each line starts with a duration in seconds. Using a zero here will fold the line with the last line with a non-zero duration. At runtime a random element from the folded lines will be selected.
Multiple tracks can be defined by vertically aligning playlist item definitions.
A playlist item definition looks like this:
In this example
frab is the name of the asset shown. It
can either be a direct subdirectory or a normal asset like
images/videos. Subdirectories must follow the "module" api
to be supported. You can have a look at
to see how that works.
In the above example
info_bar references an area defined
earlier within the configuration.
The optional json value, in that case
will be available to the used module (in that case

Future plans and documentation
The code itself isn't documented, so it might be a bit difficult to follow. I tried to make everything as clear as possible but this still isn't a substitute for proper documentation. These congress packages are always a way to play with new ideas without really knowing if they work out in the end. It seems like this year's version worked pretty well, so I'll probably further develop the approach taken in this package so it will end up being fully supported and documented. But that might take some time.
Getting all of this to run in the current state might be a bit complicated. But it should work. If you need help for your conference, please get in contact.
Adding more content
This package can be easily extended by adding sub packages
and referencing them from the schedule. During 33c3 this
approach was used for the user content that was being
This custom CMS exported its content as an info-beamer
hosted package that can added as a child package this this
package. It can then be referenced from the schedule.
During 33c3 the sub package was added in the
33c3-usercontent folder. You can still see that in the
config examples in the
