Abstract: PCT No. PCT/EP96/00049 Sec. 371 Date Sep. 2, 1997 Sec. 102(e) Date Sep. 2, 1997 PCT Filed Jan. 8, 1996 PCT Pub. No. WO97/25817 PCT Pub. Date Jul. 17, 1997Disclosed is a technique for distribution of multimedia files from file servers (110) over arbitrary telecommunication networks (150) to consumers (160) where those networks offer connections of a certain bandwidth for transmission. The consumers deliver requests for presentation of multimedia files, and the file servers deliver those files with respect to said requests for presentation. According to the proposed method, the transmission rates of the multimedia files are smoothed by spreading the transmission over time leading to additional delays in the delivery of said information. Minimum transmission rates for maximum values of the delays are calculated, and these values are provided as control data for the transmission. These control data are appended to the respective multimedia files, and the multimedia files are delivered to the receivers with respective additional delays between the requests for presentation and the presentation of the files, corresponding to the maximum delays. By the proposed method, time critical files being encoded with a variable amount of data over time, like video-on-demand files, can be transmitted with constant quality despite given fluctuations in the amount of coded data, and without any interaction of the user, and thus a continuous play-back of a demanded video is provided.

Abstract: A method of operating an availability service in a telecommunication system interconnecting a legacy telephone system with at least one presence system, said legacy telephone system including a plurality of terminals (T1 . . . T10), at least some (T1,T2) of which are terminals of subscribers to said availability service, said method including:(a) continuously monitoring each subscriber terminal (T1,T2) for a change of a call status of said subscriber terminal from the presence of a call to the absence of a call;(b) generating a first or "high availability" signal when said call status of said subscriber terminal changes from said presence of a call into said absence of a call;(c) monitoring an interval of time beginning with said first signal;(d) generating a second or "availability unknown" signal after a predetermined time period tau within said interval; and(e) making said availability signals accessible to any interconnected presence system.

Abstract: A method of operating an availability service in a telecommunication system interconnecting a legacy telephone system with at least one presence system, said legacy telephone system including a plurality of terminals (T1 . . .

Abstract: An electronic device for executing an application includes: application data, a central control unit for processing the application data according to a first method call, an interface for transmitting a description of the first method call to a second electronic device, and a synchronization entity for generating the description and passing the description to the interface. The transmitted description is used by the second electronic device to derive a second method call that is executable on the second electronic device.
