The present invention provides method and device for transcoding between audio coding formats with different time-frequency analysis domains, as used for example by MPEG-AAC and mp3, particularly for facilitated and faster transcoding between such audio signals. A method for transcoding a framed audio signal from a first parameter domain (PD A ) into a second parameter domain (PD 3 ) comprises linearly transforming (T T ) two or more parameters of the first parameter domain (PD A ) to at least one parameter of the second parameter domain (PD B ), wherein the two or more parameters of the first parameter domain come from different frames of the audio signal in the first parameter domain. The linear transformation (T T ) can be described as a matrix and implemented as a look-up table.

The present invention relates to a holographic storage system (1), and more specifically to a method for pixel detection in a coaxial holographic storage system. In a holographic storage system (1) according to the invention, with a coaxial arrangement of an object beam (3) and a reference beam (2) the bright pixels within the object beam (3) have a phase shift of essentially π relative to the reference beam (2). For readout of a data page contained in a reconstructed object beam (10) a detector (11) detects an interference pattern generated by the interference between the reference beam (2) and the reconstructed object beam (10).

An optical disc playback apparatus and a method to improve data detection performance or so-called playability of an optical disc are recommended, which remove low frequency noise caused by a deteriorated signal level of a high frequency signal read from the optical disc and provide a constant group delay for frequency signals in the high frequency signal representing the information stored on the disc for an improved playability of the disc. This is achieved by a tuned filter providing a difference signal from the high frequency signal and the high frequency signal after passing a low pass filter. According to embodiments of the invention, the low pass filter is a 2 nd order elliptical filter.

The sharpness impression when displaying a movement on an AMOLED (Active Matrix Organic Light Emitting Display) shall be improved. For this purpose, an apparatus for driving a cell of an AMOLED is provided including driving means (14, 16) for applying a driving voltage to the cell and for applying a luminance control signal to the cell during a pregiven time frame. The apparatus further includes controlling means (17, 18) for varying the driving voltage within the time frame according to a predefined function of time. For example, the driving voltage may be varied in the form of a triangle so that the lighting time over the frame is reduced while a CRT like behavior is emulated.

The invention relates to the field of network communication in a wide area, where a local network of a first type (20) has a sending station (21) that communicates with a receiving station (31) in a local network of a second type (30). A network of a third type (50) is in between the two networks (20, 30) and provides virtual private networking between the two local networks (20, 30). The network of the first type (20) supports a fine grained QoS, whereas the network of the third type (50) supports a coarser grained QoS. In one example the network of the first type is RSVP capable and the network of the second type is an MPLS network. The invention resides in a component called RSVP-MPLS proxy (100) that maps the RSVP resource advertisements and reservations within an RSVP-aware customer network to an MPLS network, whereby the receiver side doesn't participate in the RSVP communication process.

The invention relates to a method, an apparatus, and a recording medium (1) for recording multimedia content, which allow a controlled access to the multimedia content. According to the invention, the recording medium (1) for recording multimedia content has a content limitation indicator (4) for indicating which multimedia content is allowed to be recorded on the recording medium (1). A recording apparatus compares the multimedia content to be recorded with the limitations specified by the content limitation indicator (4) prior to recording the multimedia content on the recording medium (1).

The present invention relates to a method for recording data pages in a holographic recording medium, and more specifically to a method for compensating for sensitivity variations of the holographic material of the holographic recording medium. According to the invention, a method for recording data pages on a holographic recording medium has the steps of: - modulating a light beam with a spatial light modulator to generate (11) a data page with data to be recorded, and - applying (12) a compensation profile to the data pages during recording for reducing contrast variations in the reconstructed data pages.

The driving of an active matrix organic light emitting display (AMOLED) shall be improved. A pulsing grayscale rendition shall be combined with an improved motion rendition when driving the AMOLED with analog signals. Therefore, there is provided a data signal which is applied to each cell of the AMOLED for displaying a first grayscale level of a pixel of the image during a first group of sub-frames (SFO to SF5)for displaying at least a second grayscale level of a pixel of the image during at least a second group of sub-frames(SF'O to SF'5). The first group of sub-frames (SFO to SF5) and the at least second group of sub-frames (SF'O to SF'5) are constituting a video frame N. Each group of sub-frames is divided into a plurality of sub-frames. Each, the first group of sub-frames and the second group of sub-frames is belonging to a separate complete image of the display (AMOLED). The data signal of a cell comprises plural independent elementary data signals wherein each of the elementary data signals is applied to the cell during a sub-frame and the grayscale level displayed by the cell during the respective group of sub-frames depends on the amplitude of the elementary data signals and the duration of the sub-frames. With this concept, a flicker-free and a very high level of motion rendition can be offered.
