Studium Multimediatechnik

An der FH Kärnten starten  wir im Wintersemester 2018/19 den neun Studienzweig
Multimediatechnik (Studiengang Informationstechnologien).

Forschung/Projekt -> Link

Der Studienzweig Multimediatechnik beschäftigt sich mit der Erstellung, Aufbereitung und Bearbeitung  von Audio/Video Assets für professionelle Projekte für Kino, TV oder für die Werbebranche. Die Grundlagen und Konzepte von modernen Hard- und Software-Lösungen für die Aufnahme, Weiterverarbeitung und Wiedergabe von Audio-/Video- Produktionen stehen ebenso am Studienplan wie Grundlagen des Gamedevelopments bzw. die Entwicklung von Augmented und Virtual Reality Applikationen.

Der Studienzweig Multimediatechnik zeichnet sich weiters durch eine enge Kooperation mit Firmen aus dem Gamedevelopment und dem Bereich der Audio-/Video-Produktion aus. Dadurch wird den Studierenden bereits im Studium die Möglichkeit geboten, mit Professionisten zusammen an Projekten zu arbeiten.









Beowulf Raspberry Pi cluster project @FH Kärnten – Medical Engineering

For our data science and parallel computing projects at Medical Engineering we are working on a 5x Raspberry PI/Asus Tinker Node for our Beowulf cluster

The final Beowulf cluster will have 20 of this nodes with 5×20 Raspberry PI/Asus Tinker.

Currently we have 20 Raspberry PI 3B running at 1400MHz.

One of our next tasks will be the evalution of the Asus Tinker devices as a replacment option for our Raspberry PI 3B.

Rankz – an innovative middleware for sports event ranking information distribution

In one of my last posts I wrote about a young company Rarebyte. The folks from Rarebyte are mainly focused in game development but they also have a great experience in building highly scalable middleware applications for sport timing respectively sport events.

They are named their product line Rankz.

Rankz is desigend for small to very large sports events with thousands of  athletes. Its purpose is to get detailed information about every aspect of a sport event in real time. It has already been successfully used at the

Rankz is also the central core layer in a student project called “IRONNET” (FH-Sportstiming) done by students from Network Engineering & Communication (NET) and is also the overall software basis used  by “FH Sportstiming” (NET).  An older version is also operated by Triangle Show & Sports Promotion Gmb.

The middleware uses spring core layer technologies which allows them to be highlight flexible. The data structures which specify the sport event can be entirely configured through XML. A full featured editor for XML/POJO  is also available. The interface to the timing database can also be configured through XML. For this reason you are neither limited by the used format of the timing data nor to the database engine. Rankz works out of the box with MySQL, PostgreSQL, Oracle, MSSql.

Furthermore Rankz uses a dynamic plugin system. So new features can be added very easily. Plugins can be loaded and unloaded @ runtime.

    • Relative ranking at certain splits
    • Timing, average Speed, finishing context,….
    • statistic system and missed time error correction system
    • FTP plugin upload
    • Athlete’s (geographical) real time position prediction.
    • SMS/MMS Notification Service
    • Athlete’s@Twitter …
    • Virtual Athlete’s rankings (audience favorite….)
    • Position estimation
    • RESTful resource connectors
    • Webservice Revision Layer
    • Distributed mode for sport events like wingsforlife
  • Query engine
