Abstract:
Method for updating the firmware of a security module (SM3, SM4) associated to a user unit for processing digital data broadcasted in a transport stream, said unit being connected to a conditional access system transmitting, in said transport stream, to the security module (SM3, SM4) a first stream (P0) of management messages (EMM), said method is characterized in that it comprises the following steps: - broadcasting at least a second stream (P1, P2) comprising the patch messages (EP) suitable for updating the firmware of the security module (SM3, SM4), said second stream (P1, P2) being identified by an identifier (PID) associated to a predetermined type of security module (SM3, SM4), - adding to the first stream (P0) of management messages, trigger messages (T) comprising version information allowing establishing whether said security module (SM3, SM4) is up-to-date, and an identifier indicating to said security module the suitable patch stream (P1, P2), - if the current version of the firmware of the security module (SM3, SM4) is inferior to the patch version, directing the security module (SM3, SM4) towards the stream (P1, P2) of patch messages (EP) designated by the identifier included in the trigger message (T), - updating the firmware of the concerned security module (SM3, SM4) related to the stream (P1, P2) of patch messages (EP), - directing the security module (SM3, SM4) towards the first stream (P0) of management messages (EMM) when the update of the firmware is completed.

Le but de la présente invention est de proposer une solution souple au risque que représente l'accès à une mémoire temporaire d'un circuit spécialisé de décryption/décompression pour un décodeur de télévision à péage. Ce but est atteint par une méthode de transmission de données entre un centre de diffusion et une unité multimédia, celle-ci comprenant au moins une clé unique et un module de sécurité disposant d'une clé de transport, cette méthode comprenant les étapes suivantes: - génération d'une clé de session par un centre de gestion, - transmission de la clé de session au centre de diffusion, - encryption de la clé de session par la clé unique de l'unité multimédia, - transmission d'un message encrypté par la clé de transport comprenant la clé de session encryptée à l'unité multimédia, - transmission du message au module de sécurité par l'unité multimédia, - décryption du message par la clé de transport du module de sécurité et transmission de la clé de session encryptée à l'unité multimédia, - décryption de la clé de session encryptée par la clé unique de l'unité multimédia, - création d'une liaison sécurisée par l'encryption et décryption, par la clé de session, des données échangées entre le centre de diffusion et l'unité multimédia.
Abstract:
The invention provides methods of purifying antibodies using various antibody- specific purification media to rapidly and efficiently separate mixtures of antibodies, antibody fragments and/or antibody components to isolate a desired antibody product from the mixture. The invention relates to the purification of bispecific monoclonal antibodies carrying a different specificity for each binding site of the immunoglobulin molecule, e.g., antibodies composed of a single heavy chain and two different light chains, one containing Kappa constant domain and the other a Lambda constant domain, including antibodies of different specificities that share a common heavy chain. The invention also provides the methods of efficiently purifying intact antibodies by separating the intact antibody from non-intact antibodies including free light chains.
Abstract:
The invention relates to fully human monoclonal antibodies, and fragments thereof, that bind to the chemokine Regulated upon Activation, Normal T-cell Expressed, and Secreted (RANTES, CCL5), thereby modulating the interaction between RANTES and one of more of its receptors, such as, e.g., CCR1, CCR3, CCR4 and CCR5, and/or modulating the biological activities of RANTES. The invention also relates to the use of these or any anti-RANTES antibodies in the prevention or treatment of immune-related disorders and in the amelioration of one or more symptoms associated with an immune-related disorder.
Abstract:
The invention relates to fully human antibodies, and fragments thereof, that bind to interferon-inducible-protein-10 (IP-IO, CXCLlO), thereby modulating the interaction between IP-IO and its receptor, CXCR3, and/or modulating the biological activities of IP-IO. The invention also relates to the use of such anti-IP- 10 antibodies in the prevention or treatment of immune-related disorders and in the amelioration of one or more symptoms associated with an immune-related disorder.
Abstract:
The invention relates to fully human antibodies, and fragments thereof, that bind to human interferon gamma (hlFNγ), thereby modulating the interaction between IFNγ and its receptor, IFNγ-R, and/or modulating the biological activities of IFNγ. The invention also relates to the use of such anti-IFNγ antibodies in the prevention or treatment of immune- related disorders and in the amelioration of a symptom associated with an immune-related disorder.
Abstract:
Disclosed are antibodies that specifically bind Toll-like Receptor 4 (TLR-4), and to methods of using the anti-TLR4 antibodies as therapeutics and diagnostic agents.
Abstract:
The invention provides compositions and methods for generating libraries of DNA sequences encoding homologous polypeptides, and uses of the libraries to identify naturally diversified polypeptide variants. The invention also provides compositions and methods for generating collections of synthetic antibody fragments in which one or several complementary determining regions (CDR) are replaced by a collection of the corresponding CDR captured from a natural source. The invention further provides compositions and methods for diversifying a portion of a polypeptide by inserting a diversified sequence of synthetic or natural origin without the need for modification of the original polypeptide coding sequence.
Abstract:
The present invention is related to antibodies directed to the antigen CD3 and uses of such antibodies. In particular, the present invention provides fully human monoclonal antibodies directed to CD3. Nucleotide sequences encoding, and amino acid sequences comprising, heavy and light chain immunoglobulin molecules, particularly sequences comprising, heavy and light chain immunoglobulin molecules, particularly sequences corresponding to contiguous heavy and light chain sequences spanning the framework regions and/or complementarity determining regions (CDR’s), specifically from FR1 through FR4 or CDR1 through CDR3, are provided. Hybridomas or other cell lines expressing such immunoglobulin molecules and monoclonal antibodies are also provided.
