Title: Method and apparatus for artificial bandwidth expansion in speech processing
Inventor: KALLIO LAURA
IPC: G10L19/00
Filed: 2004-01-09
Abstract: A method and device for improving the quality of speech signals transmitted using an audio bandwidth between 300 Hz and 3.4 kHz. After the received speech signal is divided into frames, zeros are inserted between samples to double the sampling frequency. The level of these aliased frequency components is adjusted using an adaptive algorithm based on the classification of the speech frame. Sound can be classified into sibilants and non-sibilants, and a non-sibilant sound can be further classified into a voiced sound and a stop consonant. The adjustment is based on parameters, such as the number of zero-crossings and energy distribution, computed from the spectrum of the up-sampled speech signal between 300 Hz and 3.4kHz. A new sound with a bandwidth between 300 Hz and 7.7kHz is obtained by inverse Fourier transforming the spectrum of the adjusted, up-sampled sound.

Abstract: By comparing information on encoding to a condition associated with the encoding processing, it is possible to select information which can be re-used. If the delay mode, the picture configuration, and the pull-down mode at the previous encoding do not match with those at the re-encoding, the parameters are not re-used and when these are matched and the image frames are not matched, the picture type is re-used. If the bit rate of the previous encoding is smaller than that of the current encoding and the chroma format is greater than the current encoding, the picture type and the motion vector are re-used. If these conditions are not satisfied, a parameter is supplied and it is judged whether the chroma formats coincide. If No, information on the picture type, the motion vector, and quantization value are re-used and if Yes, stream data which has been input to a decoding section is output. The present invention can be applied to an encoding section, an encoding device, or a transcoder.

Title: Advanced method and device with a bistable nematic liquid crystal display
Inventor: MARTINOT LAGARDE PHILIPPE
IPC: G02F1/133
Filed: 2004-05-14
Abstract: The invention relates to a bistable nematic liquid crystal matricial display device wherein the shift to one of the at least two bistable states is carried out by displacing the liquid crystal parallel to the surfaces of the device, characterized by the fact that it comprises a system for addressing various elements of the display device, characterized in that it comprises a system for addressing the various elements of the display device such that it does not simultaneously shift two adjacent elements located in the direction in which the material flows. The invention also relates to a display method. The invention makes it possible to control the grey level by controlling the scan rings of the hydrodynamic flow in order to define the border between two different textures.
