Used technologies
Integration, Server and End devices

• The basis for the Lematch client implementation
  is the Java MIDP 2.0 platform as well as Windows
  Mobile 5.0.
• Lematch clients have their own persistency and
  are fully working in offline mode with the
  exception of the real time voting and betting
  features. News and statistics are stored locally
  on the device.
• Communication between the Lematch server and the
  portals (backend) is based on XML. Required
  XML-feeds may be gathered from the portals.
• Lematch server implementiation is based on Java
  J2EE and a simple Apache Webserver, optionally a
  Zope-based system.
• Data management for the community and all their
  events is part of the Lematch server.
• The Lematch server contains a billing and
  clearing interface, there is no money transfer.

Streaming Video Sequences
Tracking Data are transfomred into animated
sequences

• Wireless object and camera tracking results in
  capturing players data live and in real time.
• The Lematch Streaming Video Server transforms
  such data into animated sequences
• The data source is a video data source which
  visualises the collected tracking data and
  transforms them in short animated sequences
  (movies)
• Via the Lematch Community Server users can
  subscribe to several of these video feeds.

Use Technolgies
Streaming Video Provisioning

• Exchange between the tracking data sources and
  Steaming Video Server is via XML
• Streaming Server generates a compressed vector
  graph , optional SVG
• Tracking data will be put together with a
  timeline as vector graphs in the form of an
  animated sequence , which uses much less band
  width as video
• A 2D graphics player on the client side is able
  to store and display animated sequences with
  little processing power.

  the sport rights association. This applies to
  other events music, other forms of betting, as
  well.
