Abstract: A method and apparatus are provided for updating post-processing states applied to a decoded audio signal. The method is such that, for a current decoded signal frame, sampled at a different sampling frequency from the preceding frame, it includes the following acts: obtaining a past decoded signal, stored for the preceding frame; re-sampling by interpolation of the past decoded signal obtained; using the re-sampled past decoded signal as a memory for post-processing the current frame. A decoding method is also provided, which includes updating post-processing states.

Abstract: A method for resampling an audio-frequency signal with an output sampling frequency, for a current signal frame. The method is used when the preceding frame is sampled at a first sampling frequency which is different from a second sampling frequency of the current frame. The method includes: determining a first and second segments of the signal by adding samples at zero at the end of stored samples of the preceding frame and at the start of samples of the current frame, respectively; obtaining the first resampled segment and the second resampled segment by applying at least one resampling filter respectively to the first segment resampling the first frequency at the output frequency, and to the second segment resampling the second frequency at the output frequency; and combining the overlapping portion of the first and second resampled segments to obtain at least one portion of the resampled current frame.

Abstract: A method for processing a digital signal, implemented during decoding of the signal, in order to replace a succession of samples lost during decoding, the method comprising steps of: generating a structure of a signal for replacing the lost succession, this structure comprising spectral components determined from valid samples received during decoding before the succession of lost samples; generating a residue between a digital signal available to the decoder, comprising received valid samples, and a signal generated from the spectral components; and extracting blocks from the residue, method in which window weighted blocks are injected into the structure using an overlap-add approach, the injected blocks partially overlapping in time.

Abstract: The method and system according to a preferred embodiment of the present invention allows ensuring consistency of the PNR record when it is handled within the subsystem controlled by the reservation interceptor module and including a plurality of OBEs. According to a preferred embodiment of the present invention the PNR context on open systems is centralized to avoid its fragmentation in the distributed environment, as gathering of all the context parts implies performance issues. In addition, instead of implementing a transaction session protocol to handle a start of transaction, intermediate updates and a final commit or rollback on the PNR context, the principle of the service interceptor architecture is to delegate the functional queries with the current user PNR context which will be modified in the central repository of PNR context only at response time when the whole functional use-case is finished.

Abstract: The method and system according to a preferred embodiment of the present invention allows synchronizing the PNR values across a multi-server (possibly multi-platform) reservation system with an efficient and consistent mechanism. The mechanism addresses the consistency and performance issues thanks to its versioning and its lazy behaviour (the synchronization occurs only when required). It can be used as a solution during a migration phase from one system to another with progressive migration of applications sharing data, and also as a permanent solution for distributed applications across different platforms. According to a preferred embodiment of the present invention, the reservation services are distributed between two different platforms (e.g. mainframe and open platforms) they require sharing the same Passenger Name Record (PNR) contextual data in read and write mode to perform their business functionalities.

Abstract: In a middleware implementing an enterprise service bus (ESB) for interconnecting disparate software applications a method and a system of extending services provided by the ESB are disclosed. All incoming service requests reaching ESB from end-clients are not only forwarded to a primary server but are all, or an adjustable fraction of all of them, replicated to one or more secondary shadow servers. All replies received by ESB from the primary server and from the secondary shadow servers are validated. Validation includes the forwarding to the end-clients of a single validated reply for each incoming service request while all redundant replies are discarded. Replication of incoming service requests and validation of all replies extend the services provided by an ESB allowing e.g., to warm up a newly installed server, to bring up new software applications, to guarantee the integrity of operation of a cluster of servers and to optimize the response times.

Abstract: An interface module between a communication module and a number of instances of business logic modules of a software engine comprises first and second functional elements. The first functional element receives incoming data from the communications module and selects which of the instances of business logic modules to forward the incoming data based upon a rule set held within a data structure at the first functional element. The incoming data passes to the selected logic module instance via the second functional element. The second functional element determines either a single shot or a multiple shot mode of operation. If a multiple shot mode of operation is selected incoming data passes to the selected logic module instance sequentially. Alternatively, if a single shot mode of operation is selected a summary data record corresponding summary of incoming data received at the first function element passes to the selected logic module instance.

Abstract: The invention concerns the processing of audio data. The invention is characterized in that it consists in: (a) encoding signals representing a sound propagated in three-dimensional space and derived from a source located at a first distance (P) from a reference point, to obtain a representation of the sound through components expressed in a spherical harmonic base, of origin corresponding to said reference point, (b) and applying to said components compensation of a near-field effect through filtering based on a second distance (R) defining, for sound reproduction, a distance between a reproduction point (HPi), and a point (P) of auditory perception where a listener is usually located.
