Abstract: A simplified method to produce recombinant adeno-associated virus (AAV) vectors is described. The procedure involves the use of chimeric plasmids which incorporate the Epstein Barr nuclear antigen (EBNA) gene, the latent origin of replication of Epstein Barr Virus (oriP), and a recombinant AAV genome. The chimeric plasmids themselves are also a part of the present invention. These EBV/AAV plasmids are maintained as multicopy extra-chromosomal elements in cells, such as human 293 cells. Permanent cell lines carrying these EBV/AAV plasmids are induced to produce large amounts of recombinant AAV virus upon addition of wild-type, adeno-associated virus helper functions. Recombinant AAV vectors produced in this manner are capable of transducing exogenous genes into other human cell lines and exhibit all of the attributes of viral elements produced by conventional methods.

Abstract: An audio decoder in a multimedia processor improves decoding efficiency and performance through the usage of multiple parallel processors including a scalar processor and a vector processor. The scalar processor most efficiently performs tasks including bit manipulation, indexing and conditional operations. The vector processor most efficiently performs operations involving multiple data calculations, operating on unconditional, sequential data. Improved performance is achieved by executing as many operations as possible on the vector processor, rather than the scalar processor, so long as the data is sequential data. The audio decoder includes a requantization program code that shifts data handling operations from the scalar processor to the vector processor through the conversion of nonsequential data to sequential data, thereby "vectorizing" the data.

Abstract: The invention provides methods and devices for processing an optical signal. In one embodiment, an optical device (101) for scrambling an input optical signal comprises an optical switch (10) which switches the optical signal between two intermediate optical paths (13,14) under control of a scrambling signal from a control circuit (12). The polarisation of the signal in one of the intermediate optical paths (13) is rotated by a TE-TM converter (15). The polarisations of the two intermediate signals are thereby made mutually orthogonal. These mutually orthogonal signals are then recombined by a directional coupler (16) to provide a combined output optical signal with a scrambled polarisation alternating between othogonal states according to the frequency of the scrambling signal. The invention may be applied to improve signal reception, for example, in coherent optical transmission systems.
