摘要:
The invention is concerned with the transmission of broadband signals onto to a telephony connection having constraint profile limiting the maximum allowed power as a function of frequency. As a result, broadband signals can be delivered using low power equipment to a telephony line whilst respecting the constraint profile associated with that line.

A user accesses a destination such as a call centre 6; the call centre generates a record for insertion into the user's personal address book (e.g. at server 3) with a telephone number of the centre 6 and metadata concerning a transaction. To place a later call on the same matter, the user selects, either using his telephone or via a separate terminal, the address book entry and the call is made. The centre 6 receives the user's telephone number via the calling line identity (CLI) and translates this (at 8) into a data address whereby it can 'pull' the metadata from the personal address book at 3. Alternatively the server 3 can translate the centre's telephone number into a data address to 'push' the metadata to the centre.

摘要:
La parole entrée est codée en paramètres de filtrage de synthèse et en paramètres d'excitation à impulsions multiples pour l'excitation d'un filtre de synthèse décodeur. On choisit l'excitation de façon à réduire l'erreur entre la parole entrée et la parole synthétisée en dérivant une estimation des positions et des amplitudes des impulsions d'excitation à l'intérieur d'une tranche de temps, puis en réglant la position et l'amplitude de chaque impulsion l'une après l'autre, de façon à réduire l'erreur. L'erreur devant être considérée est l'erreur moyenne comprise dans l'intervalle de la parole synthétisée qui correspond à l'intervalle entre l'impulsion réglée et l'impulsion suivante (ou, pour la dernière impulsion, la fin de la tranche de temps).
