The invention concerns a device of a network configured for implementing a method for distributing available bandwidth of said network (N) amongst ongoing traffic sessions of devices (C, C, C) of the network (N). Said device comprises: &#x2014;a communication module () to collect status messages from devices (C, C, C) of the network running at least one traffic session; &#x2014;a ranking module () configured to rank said ongoing traffic sessions according to parameters of devices and traffic sessions retrieved from status messages; &#x2014;a calculator () configured to determine bandwidth to be allocated to each ranked traffic session in function of the available bandwidth, a rank of the ranked traffic sessions and a type of the ranked traffic session; &#x2014;a comparator () able to check whether the determined bandwidth to be allocated to a traffic session of the device is different from zero.

Method for distributing available bandwidth of a network amongst ongoing traffic sessions run by devices of the network, corresponding device

The method for assigning a tag (T) with an action for a network device (N) within a network comprising a management server (M), a control device (S) and the network device reads the tag with the control device; the tag transmitting a unique tag ID and a URL to the control device. The control device (S) reads the URL and connects with the management server (M), in case the tag has no action assigned, an action to be performed by the network device (N) is selected for the tag from a list on the control device, the management server is informed about the selected action. The management server stores the selected action in a memory of the management server, and the control device communicates with the network device (N) to inform the network device (N) to perform the action.

Method for assigning a tag with an action within a network, respective network and control device

A device of a network configured for implementing a method for distributing available bandwidth of the network amongst ongoing traffic sessions of devices of the network is described. The device includes a communication module, a ranking module, a calculator and a comparator. The communication module collects status messages from devices of the network running at least one traffic session. The ranking module is configured to rank the ongoing traffic sessions according to parameters of devices and traffic sessions retrieved from status messages. The calculator is configured to determine bandwidth to be allocated to each ranked traffic session in function of the available bandwidth, a rank of the ranked traffic sessions and a type of the ranked traffic sessions. The comparator checks whether the determined bandwidth to be allocated to a traffic session of the device is different from zero such that available bandwidth can be distributed amongst ongoing traffic sessions.

Method and device for processing digital data

A device for decoding a video stream in trick mode includes a random access source of coded video pictures, a means for establishing an order for pictures to be decoded, a plurality of reconstruction buffers for storing decoded pictures, and a video decoder for decoding coded pictures. The decoding device further includes a means for monitoring the availability of the reconstruction buffers. In one embodiment, a method of the present invention performed, for example by the coding device, includes establishing an order of decoding pictures and commanding the video decoder to decode a picture upon availability of a reconstruction buffer.

Method and device for decoding a video stream in trick mode

The invention concerns a method () and system () for performing a trick mode on a video signal containing a plurality of original pictures. The invention includes the steps of, in response to a trick mode command, selectively repeating () at least one of the original pictures to convert the video signal to a trick mode video signal having the original pictures and at least one repeated original picture and selectively displaying () at least a portion of the original picture and at least a portion of the repeated original pictures in accordance with a predetermined sequence to avoid a vibration artifact. Each original picture and each repeated original picture can contain at least two fields.

Slow video display trick mode

A process for synchronizing an MPEG decoder, characterized by the process of calculating an actual instant of presentation Tpres of the video of an image, this instant relating to a local clock LSTC, further calculating an offset STOC between Tpres, being the calculated instant of presentation and the PTS label corresponding to the instant of presentation desired by the coder for the video of this image, so as to define a virtual clock VSTC=STCO+LSTC, the presentation of the video corresponding to this image being made at the PTS dates relating to the virtual clock VSTC, wherein this process relates to satellite decoders, MPEG decoders, as well, as digital TV receivers, utilizing a hard disk for recording coded data.

Process and device for synchronizing an MPEG decoder

A method and device for decoding a packetized data stream comprising packets is disclosed. Each packet comprises a header and a payload encapsulating an elementary stream. The method includes selecting an object header in the elementary stream, inserting a packetized data stream packet header before the object header and transferring the inserted packet header, the object header, and data of the packetized data stream consecutive to the object header to a packetized data stream parser. This is applicable to digital video systems and in particular to digital television decoders.
