The present invention relates to a streaming apparatus, and a method in a network system, comprising at least a first and a second streaming apparatus () for data streaming, each being adapted to upload and store media data, comprising a plurality of media data compositions, for example representing movies and/or TV channels, the network system further comprising a plurality of user devices (). The method comprises the first streaming apparatus () receiving a plurality of streaming requests from a plurality of the user devices (), the first streaming apparatus () determining whether to stream media data compositions according to the streaming requests, sending, if the first streaming apparatus () determines not to stream a media data composition, the corresponding streaming request to the second streaming apparatus (), the first streaming apparatus () creating request information related to streaming requests received by the first streaming apparatus (), and the first streaming apparatus () determining, based at least partly on the request information, whether to upload and store a further media data composition (Mnpq).

Apparatus and a method for data streaming applications

An apparatus and a method for data streaming, as well as a combination, of an apparatus for data streaming and a plurality of user devices, are presented. The apparatus is adapted to receive a plurality of streaming requests, including mode requests, from a plurality of user devices, the apparatus comprising a memory unit adapted to store media data in the form of a plurality of payload data sets, a state device adapted to set a mode in accordance with each one of the mode requests, and a streaming unit adapted to stream the payload data sets in accordance with the set modes. The streaming unit is adapted to receive from the memory unit a plurality of control data sub-sets, each comprising at least two edit portions, each comprising data corresponding to an address in the memory unit.

Method and an apparatus for data streaming

The invention relates to a method and an apparatus for recording and streaming multimedia sequences transmitted from a data distribution device () over a data communications network (), comprising receiving a recording request; receiving a multimedia sequence (DC) relating to the recording request; removing, during reception of the multimedia sequence (DC), all information comprised in the multimedia sequence (DC) except the payload data from the multimedia sequence (DC); determining an empty memory portion (MB) in a temporary memory () of a control unit (); storing, during reception of the multimedia sequence (DC), the payload data in the memory portion (MB); writing the address of the memory portion (MB) to a second networking unit memory portion (&#x2033;); and when the memory portion (MB) is full, by means of the writing device (): writing the address of the memory portion (MB) to a third networking unit memory portion ('&#x2033;), and sending a trigger signal to a file system () of the control unit () and by means of the file system () transferring the payload data stored in the full memory portion (MB) to a memory portion (MC) of a memory unit ().

Method and an apparatus for data recording and streaming

A method is disclosed of using a plurality of simultaneous communication sessions to allow two-way communication where data compositions are simultaneously sent from an apparatus to a large plurality of remote units, while maintaining a high performance of the apparatus, each session involving sending a data composition to a respective of a plurality of remote units through a communication network, the data compositions being stored in a storage unit. The method includes receiving from the storage unit streams of data composition sub-sets, and providing for each of the communication sessions a data queue, and storing data of the streams of data composition sub-sets in the data queues.

Method and an apparatus for data storage and communications

Method in a pipeline processing stage in a processor, includes the steps of: receiving a first block from a first register and a first execution parameter associated with the first block from a second register, the execution parameter having a first value; inspecting a set of data being at least a part of the first block; and, if the set of data differs from a predetermined condition, storing a second execution parameter on a third register and a third execution parameter on the second register, where the second execution parameter has a second value and is associated with the first block and the third execution parameter has the first value and will be associated with a second block. The invention also relates to the pipeline processor, a module, an integrated circuit and a computer unit.

Method and apparatus for processing blocks in a pipeline

The present invention relates to methods and an apparatus for switching data. According to the invention, storage means providing three or more frame buffers are used for temporarily storing frames of time slot data received via an input port of said apparatus. Read and write pointers are provided to designate which of said frame buffers that are used to be read/write accessed at each point in time. Control means are provided for controlling the operation of said pointer means, said control means being arranged initiate said read pointer means by detecting which one of said first signal and said second signal that is received first in time after a selected point in time and to control one or both of said pointer means so that, if said first signal is received first, the frame buffer designated by said write pointer means is at least two frame buffers ahead, in said round-robin fashion, of the frame buffer designated by said read pointer means, or so that, if said second signal is received first, the frame buffer designated by said read pointer means is at least two frame buffers ahead, in said round-robin fashion, of the frame buffer designated by said write pointer means.

Buffer management method and apparatus

Apparatus () for processing pipelined data, comprises a storage unit and at least one logic unit () for executing operations on a block () of data. The storage means comprises an instruction table () comprising at least one instruction, and the at least one logic unit () is in at least one pipelined processing stage adapted to receive the block () and a first instruction () of the at least one instruction and execute the first instruction (). The invention also relates to a method for processing pipelined data, a module () for processing pipelined data, an integrated circuit (), a circuit board assembly (), a computer unit () and a pipelined processing system.

Apparatus and method for processing pipelined data

The present invention refers to an apparatus for time and space switching data from a first and a second input signal to a first and a second output signal, said apparatus comprising at least four switch elements, each having a first and second input port and an output port. Each one of the switch elements comprises switching means arranged to provide for time-switching of data received from said first input port to provide an output referring to said output port and selecting means for defining a signal to be outputted from said output port by selectively combining said output from said switching means and data received via said second input port, the mutual order of said data received via said second port being the same when incorporated into said signal as when received via said input port.

Switch apparatus

A method and an apparatus for switching data between a set of input bitstreams and a set of output bitstreams in a circuit switched time division multiplexed network is presented. Each bitstream is divided into recurring frames and each frame is divided into time slots. Each one of the input bitstreams is received, and frames of time slot data thereof are temporarily stored in a set of memories. Each of the memories is used for storing frames of a respective bitstream of the input bitstreams. For each frame of each one of the output bitstreams, and sequentially in accordance with the order that the time slot data are to be transmitted in the respective output frame, time slot data is selectively read from frames presently temporarily stored in the set of memories, and is then transmitted into allocated time slots of the output bitstreams.
