Abstract: Selon l'invention, pour améliorer, simplifier et optimiser l'évaluation de canaux de transmission sans fil dans des systèmes de télécommunication, les corrélations de différentes réponses d'impulsion de canal sont exploitées de différentes façons. Par exemple, un des deux messages, destiné à un autre émetteur/récepteur, est utilisé pour l'évaluation de canaux. En outre, ou selon une variante, la différence entre deux réponses d'impulsion de canal est déterminée. Si cette différence est inférieure à une valeur limite, une réponse moyenne d'impulsion de canal est formée et/ou, ensuite, dans une rafale sur deux, des séquences d'informations d'apprentissage ou des signaux d'essai ne sont pas transmis. En outre, ou selon une variante, la mise en corrélation des deux réponses d'impulsion de canal au moyen de tables à consulter peut être utilisée pour l'évaluation de la vitesse d'un abonné.

Title: Multimedia compression, coding and transmission method and apparatus
Inventor: MYERS KELLY LEE
IPC: H04N19/00
Filed: 2000-06-21
Abstract: A system, method and apparatus for the compression, coding and transmission of multimedia data. This system encompasses the content creation step of capturing or creating the raw multimedia data and converting it into compressed and encoded multimedia data, the transmission step of adaptively requesting variable levels of information from the multimedia storage device based on the capabilities of the display device and the conditions of the communication channel, and the rendering step which presents the multimedia data to the intended audience. The method encodes the multimedia data in such a way that the rendering device can request at any time any variant of the original multimedia data thus optimising the bandwidth that is available, and presenting the best possible rendition of the original source data to the audience. The encoding algorithm is structured such that the compression may not be optimal for storage, but is optimal for parsing, transmission, and display.

IPC: G06Q10/00
Filed: 2000-11-17
Abstract: The present invention relates to a method and apparatus for processing entries stored in an electronic database where each entry comprises a succession of data values of correlated variables. The entries are processed in order to provide predictions of future data values of the correlated variables. The invention has particular application to processing data entries that relate to customers of a bank or retail business so as to predict future data values of attributes of the customers. A prior distribution over the parameters of a first of the variables is accessed from the database and data values of the first variable are used to derive a posterior distribution of the parameters of the first variable. A prior distribution over the parameters of a second of the variables is accessed from the database, the second of the variables being correlated with the first. Data values of the second variable are accessed to derive a posterior distribution of the parameters of the second variable. A  statistical sampler samples the parameters of each posterior distribution to provide estimates of the parameters of the posterior distributions. Predictive distributions of the first and second variables are computed from the estimates. Predicted data values for the first and second correlated variables are then formulated from the predictive distributions and known values for the variables.

Abstract: An apparatus for serving data employs a web server and a communications interface operable to enable the web server to send and receive messages on a wireless digital packet network, to act as a wireless web server. A method of serving data involves receiving a data request message from a wireless digital packet network, requesting data from a wireless web server in response to the data request message and transmitting on the wireless digital packet network a response message including data produced by the wireless web server in response to the data request message. A method of requesting data from a server involves transmitting a message on a wireless digital packet network for use by a wireless web server operable to receive messages from the wireless digital packet network. Transmitting the message may involve producing a wireless digital packet network message containing a Transmission and Control Protocol/Internet Protocol (TCP/IP) message. The method may further involve receiving, from the wireless digital packet network, a message produced by the wireless web server.
