Definitions

  • the invention relates to a method for transmitting information and to an arrangement for carrying out the method.
  • transmission encompasses the processes during transmission and / or reception.
  • the Internet service providers are unable to guarantee immediate and stable access to the data network at all times.
  • the packet network is often extremely busy, even during peak times, so that an effective exchange of information or data is not always guaranteed.
  • the invention is therefore based on the object of specifying a method and an arrangement for carrying out the method, with which the access to and exchange of information of different information formats (fax, voice, email, Video, images, data, ...) or different media formats can be done as efficiently as possible.
  • Different information formats also mean different types of media format. For example, in the context of this application, two different email types A and B are two different information formats.
  • a first information format of transmitted information is converted into a second information format that corresponds to the information format of the receiving communication terminal.
  • the invention is therefore based on the idea that the information sent by communication terminals of different media types is converted into the media type that can be processed or displayed by the receiving communication terminal. This can be done automatically after processing information via the information format corresponding to the receiving communication terminal and can also be carried out in a central processing device.
  • the invention enables access to and exchange of information of different information formats.
  • the different information formats of transmitted information are ner processing device converted into a uniform information format, and this uniform information format of the information to be received m converted into different information formats that correspond to the information format of the receiving communication terminals.
  • the further development is therefore based on the idea that the information of different media types sent or to be received by communication terminals is converted into a uniform information format in a processing unit of a communication network, and the information is converted to the media type before the message is received in the receiving communication terminal can be processed or displayed by this communication terminal.
  • UMF Unified Media Format
