摘要： A video codec for a videophone terminal of an integrated services digital network. The codec is organized to receive firstly image signals from a television camera so as to transmit them, after compressing and encoding them, to a remote video decoding unit, via a digital transmission line, and secondly similarly-processed image signals via the digital transmission line, so as to decompress and decode them for a television screen receiver locally connected to the video codec. The video codec includes a processing unit, of the integrated circuit type, co-operating with a single external memory plane both to compress and encode data to be transmitted, and also to decompress and decode received data, with the assistance of internal operational components time shared so as to apply known methods to transmission and to reception.

摘要： A GPS receiver includes an RF front end for acquiring and tracking a satellite signal and a baseband processor configured to preserve power. The baseband processor includes a GPS engine configured to process the satellite signal and generate a PVT fix, a power supervisory module for receiving the PVT fix, and a user state module that determines an environmental state, wherein the power supervisory module may power down the GPS receiver for a period of time based on a result of the determined environment state. The baseband processor also includes a time-based management module that adjusts the TCXO in response to the determined environmental state. The GPS receiver includes a plurality of operation modes, each of which is associated with a plurality of tracking profiles.
