摘要:
The invention relates to a method for inserting a new device (x) in a community of devices wherein each device of the community is able to store insertion requests received from at least one new device and to forward these insertion requests to a device (b) chosen by a user (3) of the community for confirming authorization to join the community.

The process is characterized in that the step of intra prediction comprises: a step of motion estimation of a neighbouring part (1) of the current block (a, b, c), which is already coded, within the reconstructed part of the image, to get a correlated part, a step of defining a predicted block according to the correlated part and to the position of the current block regarding the neighbouring part.

The present invention relates to a new method for generating motion compensated picture by interpolating two consecutive source pictures without using motion estimator. For a given pixel to be interpolated, all displacements within a given search range between former and next frame are considered anf for each displacement the displaced block difference is calculated. The pixel value is then equal to the sum of each averaged pixel pair within the search range weighted by a correlation coefficient funtion of the corresponding displaced block difference.
摘要:
The present invention provides a method of providing secure communication of digital data between devices, said method comprising the steps of communicating from one device an identifier of a device to an independent security module and performing device validation depending on the identity of the received identifier.
摘要:
The invention concerns a method for protecting digital data stored in a memory (4) and previously encrypted with an encryption key. The inventive method is characterized in that said encryption key is dynamically defined on the basis of at least one operating parameter intrinsic to said smart card.

The invention concerns a method for transmitting digital television services via a gateway capable of receiving a plurality digital multiplexes, each multiplex comprising at least one digital audiovisual service, the gateway being capable of receiving a limited number of multiplexes among said plurality and of transmitting them to at least one terminal. In order to improve access to the services when the gateway reaches its capacity limit, the gateway transmits (43) a list of at least one available service, to at least one of the terminals, the available services being present on the multiplexes which the gateway can receive the list of available services depending on possible services already transmitted to at least one of said terminals.
摘要:
The invention concerns a panel whereof at least one of the upper electrodes is common to a plurality of diodes (5, 5') and comprises a first conductive layer (31) and a second conductive layer (33), and an isolating and transparent buffer layer (32) which is interposed between said two conductive layers (31, 33) and which is perforated with windows which provide direct contact zones (4) between the two conductive layers (31, 33) of said common electrode (3), said contact zones (4) being separated from the active zones of the diodes (5, 5'). The presence of said direct contact zones between the two conductive layers, enables a good distribution of current to be provided by the upper electrode while the intermediate buffer layer is insulating.
摘要:
A digital satellite television system has a plurality of set-top-boxes associated with a plurality of end users' television receivers, a modem and a decoder housed in each STB, a Subscriber Authorization System (SAS) incorporating or having associated therewith a plurality of communication servers, means included in the SAS for generating Electronic Managements Messages (EMM), a back channel interconnecting each of the STBs individually with the SAS, means included in the SAS and each STB so that the necessary information required to inject a relevant EMM into the system is supplied directly to the relevant communication server included in or associated with the SAS to authorise the release of the said EMM and/or means to connect the modem to the back channel and means whereby an EMM is transmissible to the decoder directly from a relevant communication server included in or associated with the SAS. Further important features are also disclosed.
