Abstract:
1. A method for the transmission of multimedia data between at least two communication devices which are connected together over a data network, each of the communication devices having an associated coding device and an associated decoding device connected thereto, comprising: performing source- and channel-coding on multimedia data to be sent, using a coding method furnished within the coding device associated with a first communication device, which sends the multimedia data; performing inverse source- and channel-coding on multimedia data received, using a decoding method furnished within the decoding device associated with a second communications device, which receives the multimedia data; transmitting and receiving coded multimedia data using an associated transmitting and receiving device arranged between the data network and the coding and decoding devices; when there is a connection setup which cannot be implemented due to incompatible coding and decoding methods: identifying a connection setup which cannot be implemented due to incompatible coding and decoding methods, using a monitoring device arranged within a control device; sending a first identification from the monitoring device to a signaling device arranged within the control device, the first identification indicating incompatibility; sending a signal for polling the decoding method furnished within the decoding device associated with the second communication device, the signal being sent by the signaling device; transmitting a second identification from the second communication device to the control device in dependence on the decoding method furnished within the decoding device associated with the second communication device; sending a third identification from the control device, the coding method of the first communication device being identified with the third identification, the third identification being sent to the converting device; and converting the multimedia data within the converting device in dependence on the second and third identifications.
