摘要： A first aspect of the present invention concerns a method for controlling a multimedia application on a terminal, in particular a mobile terminal, wherein multimedia data are received from a remote source and are processed for being presented on a display of the terminal, comprising the steps of: a) detecting an operating state of at least one service component of the terminal concerning the presentation of the data of the multimedia application; b) generating an item of state information characterizing the operating state of the at least one service component; c) generating a message, comprising: the state information, and/or an item of information characterizing the state information, which characterizes the data density that can be processed as a maximum prescribed by the operating state of the service component for presenting the multimedia data, and/or an instruction to the remote source with respect to the adaptation of the data and/or transmission of the data to the terminal, in order to adapt the data and/or the transmission of the data to the data density that can be processed as a maximum prescribed by the operating state of the service component for presenting the multimedia data; d) transmitting the message to the remote source; e) receiving the multimedia data; and f) processing the multimedia data for presentation on the display of the terminal. The invention also concerns a method for the adaptation and transmission of multimedia data, a software product and a device.

摘要： The invention relates to a telecommunications assembly (10) and a method for traversing an application layer gateway firewall (40) during the establishment of an RTC communication connection between an RTC client (20) and an RTC server (30) using a proprietary RTC signalling protocol, wherein the firewall (40) has no specific knowledge of the proprietary RTC signalling protocol. The method comprises the following steps: the RTC client (20) and the RTC server (30) negotiate during the establishment of the RTC communication connection which of the ports (P1, P2, P3) of the firewall (40) are required for the data packets to be exchanged via the RTC communication connection, wherein they use at least one standardized message element as a component of the proprietary RTC signalling protocol, with which information relating to the ports to be used can be found; during the establishment of the RTC communication connection the firewall (40) detects, with the aid of the standardized message element, which of the ports (P1, P2, P3) of the firewall (40) are considered by the RTC client (20) and the RTC server (30) to be necessary for the data packets to be exchanged via the RTC communication connection; and the firewall (40) opens and closes the required ports (P1, P2, P3) in a dynamic manner according to the result of the negotiation.
