Abstract: The invention concerns a 1. Method for interfacing communication between a first device on a first network and a second device on a second network, the networks being connected by an interface device, the method being carried out by the interface device and being characterized by the steps of: detecting a first message on the first network, said first message being generated by the first device, said first message being relevant for the second device; translating the first message into a format compatible with the second device; sending a second message to the second device on the second network, the second message informing the second device that the first message has been detected; upon reception of a request from the second device, transmitting the translated first message. The invention also concerns a device for implementing the method.

Abstract: So-called LCH packets are defined in the Hiperlan Type 2 System for wire-free transmission of video and audio data streams. These LCH packets have a length of 54 data bytes. Furthermore, the Hiperlan/2 Standard provides for so-called ARQ messages to be sent back to the transmitter in an SCH packet in a QOS mode (Quality Of Service), in which all the LCH data packets must be confirmed by the receiver. Space for the LCH and SCH data packets must be provided in a buffer store in the Hiperlan/2 interface for each connection that is set up. When there is a possibility of several hundred connections having been set up, separate reservation of memory areas for LCH and SCH packets would involve considerable complexity for the memory organization. The invention proposes that only one common area be reserved for LCH and SCH packets in the buffer store. The section which is provided for each LCH package is of such a size that it corresponds to a value 2n where n&egr;[0, 1, 2, 3, . . .

Abstract: The invention relates to a way of implementing the so-called “late” check according to IEC 61883 in a link layer IC for the IEEE 1394 Serial Bus in a way which is favourable in terms of expenditure. According to the invention, a specific time model is used which, during the checking of the up-to-dateness of a data packet by comparison with the current bus time, also substantially simplifies the necessary comparison operations by virtue of the fact that it is possible to represent only sections of the time axis by means of a data word with limited bit length.

Abstract: The invention relates to a method for operating a network of interface nodes (3), in particular IEEE 1394 interface nodes, and to an interface device for carrying out the method. In the network, interface nodes (3) are connected via a data bus (1). At least one of the interface nodes (3) in each case receives self-ID information from others of the interface nodes (3), with the self-ID information comprising self-ID data. The at least one of the interface nodes (3) forms joint information with joint header data and joint ID data for the self-ID information which has been received from the others of the interface nodes (3), and writes the joint information to a memory device in the at least one of the interface nodes (3).

Abstract: Two or more electronic devices (1, 3, 4) are connected via a bus system (5), wherein one of the network devices controls (1) other network devices (3, 4). A first control applica-tion is uploaded from a first controlled device to the con-trol device and a second control application is uploaded from a second controlled device into the first control ap-plication. The first and second controlled devices can be operated simultaneously using a single user interface shown on a display of the control device. The user interface of the first device is displayed as main user interface and the user interface of the second device is rendered within the main interface as reduced user interface, which includes only operation elements necessary for operation of the sec-ond device in combination with the first device. The genera-tion of combined user interfaces is also possible when the second controlled device comprises features, which are not known at the production of the first controlled device.

Abstract: Two or more electronic devices are connected via a bus sys-tem (5) building a cluster or chain of devices (1, 3). A de-vice can be selected using a control device (1), wherein an user interface (6) for the selected device is generated based on description data which are stored in the selected device and are transferred to the control device. A single user interface is shown on a display of the control device which allows to operate at least two devices (1, 3) simulta-neously. The user interface of a first device is displayed as main user interface and the user interface of a second device is rendered within the main interface as reduced user interface (9) which includes only operation elements neces-sary for operation of the second device in combination with the first device.

Abstract: The IEEE1394 bus communication protocol has three layers: physical layer, link layer, and transaction layer. A link layer IC implements the interface to an external application and prepares data for sending on the bus, or interprets incoming data packets from the IEEE1394 bus. A physical layer IC implements the direct electrical connection to the bus and controls many functions including arbitration for sending data on the bus. A problem exists due to the fact that the header data of the IEEE1394 asynchronous data packets consists of 32 bit words which have to be interpreted as 32 bit words in the connected application data processing unit (30). The IEEE1394 bus interface unit (20) is defined to be of big endian type. In a little endian type application data processor (30) the data word order can only be correctly interpreted after a byte order change.

Abstract: The present invention relates to a hand-held device (1) comprising connection means for supporting an internet data transmission link between the hand-held device (1) and the internet (4); browser means for fetching internet data from the internet (4); input means for receiving a user input; and generating means for generating a command script in response to said user input, where said command script is related to said searched internet data; where said command script, when the hand-held device (1) is connected to a multimedia home device (5, 7, . . . , 14), can be processed to initiate a transmission of at least part of said searched internet data and/or other internet data to said multimedia home device (5, 7, . . . , 14).

According to the invention the capacity of the on-chip memory becomes assigned in a flexible way in order to be able to meet the requirements for any specific service. Further, the on-chip memory is prevented from storing data packets containing transmission errors by CRC checking on the fly header data and other data. This is performed for asynchronous data packets as well as isochronous data packets, and allows to have a minimum on-chip memory capacity only.
