Abstract: VPI/VCI of an ATM cell is translated into an internal Id by distributing VPI/VCI entries into sections in a table according to a portion of each VPI/VCI entry. A section to be searched according to the portion of a VPI/VCI of the received ATM cell is selected; and a search over the selected section is performed to find an entry corresponding to the VPI/VCI of the received ATM cell. An internal ID corresponding to the found entry is outputted.

Abstract: A user terminal exchanges information with a server through a transmission medium. A coupling unit couples the user terminal to the transmission medium in accordance with information from the server. Likewise, the server is controlled in accordance with information from the user terminal. In this manner, communication is created and performed between the server and the user terminal. The user terminal may be a Set-Top Unit which may be adjusted to the transmission medium by, for example, a physical medium converter or the communication itself between the Set-Top Unit and the server may be adjusted as directed by programs installed in the Set-Top Unit which may originate from the server.

Abstract: The present invention relates to a system of program objects and program components and communication between program objects and program components. The present invention provides a program component with an external or send interface which enables message passing communication between a program component and different program objects. When a program component is loaded, the send interface of the program component is automatically exported to the send interface of the host object. This means that the send interface of the object is modified to contain the send interface of the program component. Therefore it is possible to communicate by message passing between program components of a program object and other program objects.

Abstract: Method and apparatus for performing communication between a first program object, a second program object and/or a further program object, comprising the steps of: a) storing of intermediate results in a first memory part after execution of the first program function of the first program object; b) storing of an object identifier identifying the further program object in the first memory part; c) storing of a function identifier identifying a program function of the further program object; d) identifying the first memory part with a continuation identifier; e) identifying the first memory part with a continuation type; f) delivering a first message, the continuation identifier and the continuation type to a first program function of the second program object; g) executing said first program function of the second program object; h) delivering of the intermediate results to said program function of the further program object identified by the continuation type; i) executing said program function of the further

Abstract: The present invention provides a storage medium unit, comprising: storage means for storing information data; table means for memorizing data which represent a relation between routing information and said information data; memory means for storing program data for controlling the operation of the storage medium unit; control means for controlling the storage means, the table means and the memory means according to the program data; and at least one interface for transmitting the information data with the routing information for such information data in the form of a packet to routing means.

Abstract: A method of generating code for a software program in multiple languages by converting input specification files into output code files. The input specification files contain a list of distinctive features of the software program to be generated and are written in a prescribed input language. The input specification files are converted into a set of nodes representing the logical relationship between the distinctive features listed in the input specification files. Output code files are then generated from the set of nodes using external guideline files that contain guidelines for generating code. Output code files are generated in at least two code languages.

Abstract: A system for serving information comprises routing means for routing information to end devices and one or more storage units connected to the routing means. Managing means connected to the routing means manages distribution of the information data in response to identification data from an end device. Navigation means connected to the routing means provides information as to available information data and identification data thereof, wherein the navigation means provides data for navigating to an end device, and wherein at least one end device displays video information and outputs the identification data selected by a user.
