An apparatus () and method () for rendering a tree structure in a GUI depending on a position of a pointing cursor relative to the rendered tree use the cursor position with respect to the tree to control which tree branches to expand/collapse automatically. They reconfigure the tree view for compact presentation without need for explicit expand/collapse operations. A tree view is generated (). A cursor position relative to the view is determined (), consisting of first and second position values according to first and second directions. The branch the cursor position is aligned with according to the first direction is automatically selected as active branch (). Sub-levels of that branch to be expanded are determined (), depending on the second position value relative to indentations of the sub-levels, and the tree view is automatically updated by expanding the determined sub-levels of the active branch and collapsing other branches ().

A method and an apparatus for rearrangement of media data using visual representations of the media data are described. A displaying unit displays visual representations of media data items in a temporal order according to temporal metadata of the media data items. An operation unit changes the position of the visual representation of a first media data item upon receipt of a user input. Automatically, the position of the visual representations of some other media data items are changed corresponding to the position change of the visual representation of the first media data item.

A method and an apparatus for prioritizing a metadata item associated to audio or video data are described. A metadata item is retrieved from a metadata repository or via an input. An analyzing unit determines a priority value of the metadata item using one of a plurality of prioritization methods. A storing unit then stores the priority value in a priority table and references the priority table in a metadata table.

A method of managing a packet administration map for data packets to be received via a network. A receiver in the network monitors sequence numbers and stores missing sequence numbers within an internal data structure, called a packet administration map. A reversed keying is used which means that the upper limit of the range of contiguous missing data packets is used as the key entry in the administration map.

The invention relates to the field of network communication in a wide area, where a local network of a first type has a sending station that communicates with a receiving station in a local network of a second type. A network of a third type is in between the two networks and provides virtual private networking between the two local networks. The network of the first type supports a fine grained QoS, whereas the network of the third type supports a coarser grained QoS. In one example the network of the first type is RSVP capable and the network of the second type is an MPLS network. The invention resides in a component called RSVP-MPLS proxy that maps the RSVP resource advertisements and reservations within an RSVP-aware customer network to an MPLS network, whereby the receiver side doesn't participate in the RSVP communication process.

In the method for management of data transmissions in a network, switching means are provided, by means of which a change can be carried out between a first data transmission type and a second data transmission type, as alternative data transmission types between a transmitter and a receiver. The change is carried out on the basis of at least one respectively predetermined criterion. The first data transmission type corresponds to a transport protocol based on rate-based overload control. The second data transmission type corresponds to a transport protocol based on RTT-based overload control.

Optimized selection of transmission protocol respecting thresholds

In the method for operating a multi-port bridge for the routing, differentiated in accordance with traffic classes, of data packets which are subdivided into different priority classes in accordance with the IEEE802.1D standard, an additional traffic class 'isochronous channel' is introduced. The multi-port bridge is configured in such a manner that at least one predetermined port in the case of unidirectional transmission and at least one predetermined port pair in the case of bidirectional transmission is operated in the 'forwarding' state in which the predetermined port or the predetermined port pair forwards data packets of the additional traffic class IC from a queue. During the forwarding, all ports are deactivated with the exception of the predetermined port or port pair. The isochronous data stream is not restricted to one port or port pair but can be executed several times in dependence on the data rate of the transmission channel.

A distributed storage system able to support real-time recording of streaming data shall be provided. Therefore, on the basis of Material Exchange Format (MXF) formatted files a data stream is packed into at least a first MXF formatted file and a second formatted MXF file. First connection data are inserted into the first MXF formatted file, wherein this first connection data points to the second MXF formatted file. Furthermore, second connection data are inserted into the second MXF formatted file, wherein the second connection data points to the first MXF formatted file. These connection data inserted as metadata into the MXF formatted files enable both seamless real-time stream recording and stream-able data playback.

A method and apparatus for file access in a storage access network (SAN) wherein a portion of a first file is accessed and an access rate computed based on time and amount of data accessed. If the computed access rate is less than an expected rate, a problem is identified and analysis performed. A first analysis accesses the first file through a second link to determine if the link is the problem. If the first file is accessed at an expected rate, the first link is identified as the problem and the file is accessed through an alternate link. A second analysis accesses a second file through the first link. If the second file is accessed at an expected rate, the first file is identified as the problem and the second file is accessed through the first link.

It is desired to link photo data and video data taken by a digital camcorder. Therefore, there is provided a device and method for linking multimedia data, wherein linking information is formed on the basis of first and/or second multimedia data. The linking information is stored on a recording medium together with the first multimedia data. The second multimedia data may be stored together with respective linking information to the first multimedia data on a second recording medium. Thus, a camera-man while recording is able to set up logo or index pictures for a video film.

Modern computers () come with different timers having different attributes like time resolution, supported time range and time reference. Some are local timers, representing relative time values like the TSC counter () counting CPU cycles from the power on or reset of the computer. Some are global timers, representing an absolute or real time. Having different classes of timers in the computer (), a number of computations need to be performed to tie the different timers to each other. It is the idea of the invention to define a single high resolution timer structure wherein the time value is represented with a digital number and a flag clarifies whether the timer is a global timer or local timer. The invention enables a much faster processing of the time values. The global time, tied to a high-resolution timer can be tracked much faster. This means better precision of scheduling of time critical jobs, like packet scheduling for data transport.

The invention relates to a new type of quality of service architecture for a network assembly and a corresponding computer network system. The Internet technology as approved by the IETF organization has defined different services. One is the integrated services (IntServ) and the other the differentiated services (DiffServ) architecture. Another is the RSVP Protocol according to which Quality of Service can be implemented with accuracy and richer functionality. The invention shows a way how less sophisticated QoS managers inside the network with only DiffServ or Intserv capability, can be used for enhancing the QoS functionality based on so-called RSVP shadowing messages, and easy to implement RSVP shadowing stacks.

A method of operating a network subnet manager, in particular Infiniband network subnet manager in a subnet of a network. Only one subnet manager entity can be master within a subnet. A problem related with this specification is that a specific vendor implementation may exist with many features and internal functionality that are not specified in the network specification. If such a subnet manager loses its exclusivity because another subnet manager enters the subnet, having higher priority, the additional features from the vendor implementation can no longer be used in the subnet. The proposed method solves this problem by allowing a subnet manager that has a lower hierarchy level and thus lower priority to maintain its managing operation by becoming the master subnet manager again.
