Abstract: An autostereoscopic display device uses a converged backlight output, and the convergence is performed with a light converging arrangements (60,62) which preferentially converge light inwardly along a certain axis perpendicular to the elongate axis of the lenticular elements (11). This means that the amount of light directed at large angles sideways between the lenticular elements (11) is reduced to a minimum. This reduces the amount of light tunneling within the lenticular array and therefore improves the display output, in particular the brightness and contrast.

Abstract: The invention proposes a method of filtering a bitstream according to user specifications. The proposed method uses a semantic description and a syntactical description of the bitstream. The semantic description is scanned to select the elementary units that match the user specification. The time is used as a linking mechanism between the semantic description and the syntactical description to locate the elements of the syntactical description that are to be removed. A filtered syntactical description is generated by removing the located elements. Finally, a filtered bitstream is generated from the filtered syntactical description.

Abstract: In a sinusoidal audio encoder a number of sinusoids are estimated per audio segment. A sinusoid is represented y frequency, amplitude and phase. Normally, phase is quantised independent of frequency The invention uses a frequency dependent quantisation of phase, and in particular the low frequencies are quantised using smaller quantisation intervals than at higher frequencies. Thus, the unwrapped phases of the lower frequencies are quantised more accurately, possibly with a smaller quantisation range, than the phases of the higher frequencies. The invention gives a significant improvement in decoded signal quality, especially for low bit-rate quantisers.

Abstract: The invention relates to a method for contacting a flexible sheet to a first element with improved lateral alignment. The method includes a step of measuring a first lateral misalignment after establishing a first contact between the flexible sheet and either of the first element and a sheet parking surface called anchor in the first stage. If the 5 misalignment exceeds a predetermined threshold the flexible sheet is parked at the anchor such that it is not in contact with the first element, and the relative position of the first element and the anchor is altered during the second stage for correcting the mismatch during a contact between the flexible sheet and the first element to be established within the next step of the method. During the steps of shifting the contact point to obtain the second stage 10 the contacting process is more accurate and reproducible than the process for establishing the initial contact.
