Title (EN) REDUCED POWER CONSUMPTION
(FR) PUISSANCE CONSOMMEE REDUITE
Abstract:
(EN) A radio frequency receiver for receiving supplementary data transmitted with a radio station signal, said supplementary data comprising one or more information word fields containing supplementary data transmitted with the radio station signal, said receiver comprising: a host processor for processing said supplementary data; a supplementary data demodulator and decoder for demodulating and decoding a received radio signal to generate a stream of bits representing one or more information word fields; a information word type memory for storing one or more information word type fields; detection circuitry arranged to receive and compare the information word type field decoded by the supplementary data decoder with one or more information word type fields stored in the information word type memory, and to provide a matched condition signal in response to a match between one or more decoded information word type fields and one or more of said corresponding stored information word types fields, and wherein the receiver is arranged to, in response to the matched condition signal, cause the corresponding supplementary data to be processed by means of the host processor.
(FR) L'invention concerne un récepteur radiofréquence destiné à recevoir des données supplémentaires transmises avec un signal de station radio, lesdites données supplémentaires comprenant un ou plusieurs champs de mots d'information contenant des données supplémentaires transmises avec le signal de station radio, ledit récepteur comprenant : un processeur hôte destiné à traiter lesdites données supplémentaires, un démodulateur et un décodeur de données supplémentaires destinés à démoduler et à décoder un signal radio reçu afin de générer un train de bits représentant un ou plusieurs champs de mots d'information ; une mémoire de type de mots d'information destinée à stocker un ou plusieurs champs de type de mots d'information ; des circuits de détection conçus pour recevoir et comparer le champ de type de mots d'information décodé par le décodeur de données supplémentaires avec un ou plusieurs champs de type mots d'information stockés dans la mémoire de type mots d'information, ainsi que pour produire un signal de condition de correspondance en réponse à une correspondance entre un ou plusieurs champs de type de mots d'information décodés et un ou plusieurs desdits champs de type de mots d'information stockés correspondants, le récepteur étant conçu pour, en réponse au signal de condition de correspondance, amener les données supplémentaires correspondantes à être traitées par le processeur hôte.
