Patent

CA 2537465

A method of receiving a bit-stream and extracting data from the bit-stream based on one or more criteria and sub-sampling (for example, filtering and decimating) the extracted data in the transform domain. The method either stores the data for future transmission or transmits the data to one or more connected devices, such as a mobile terminal or a fixed terminal.

La présente invention se rapporte à un procédé qui consiste à recevoir un train de bits, à extraire des données dudit train de bits sur la base d'un ou plusieurs critères, et à sous-échantillonner (par exemple, filtrer et réduire) les données extraites dans le domaine de transformation. Selon ledit procédé, les données sont soit stockées en vue d'une transmission ultérieure, soit transmises à un ou plusieurs dispositifs connectés, tels qu'un terminal mobile ou un terminal fixe.
