Abstract: The present invention relates to a device in a corresponding method for encoding a secondary information (r) of a secondary channel into a channel data stream (3) of a primary channel, said channel data stream (3) comprising at least two symbol rows of channel symbols one-dimensionally evolving along a first direction (t) and aligned with each other along a second direction (r), said two directions constituting a two-dimensional lattice of symbol positions.

Abstract: A method for enhancing a video image by processing a video signal includes inputting a video signal and boosting color saturation or lightness of the video signal as a its hue gets closer to a secondary color, and/or shifting the hue of the video signal toward one or more secondary colors.

Abstract: An active matrix array device has a plurality of matrix array elements (100), each of which have a first capacitive device (120) coupled to a charging conductor (32m) via a first switch (100) being responsive to an addressing conductor (22n). In addition, the matrix array elements (100) comprise a second capacitive device (130) coupled to the first capacitive device (120) via a second switch (112) being responsive to en enable signal provided via an enable conductor (42n). The second capacitive device (130) is coupled to the control terminal of a third switch (114), which is coupled between the first capacitive device (120) and a potential source like the charging conductor (32m). The second capacitive device (130) is used to sample the voltage across the first capacitive device (120), which enables the third switch (114) if of an appropriate value, thus providing a conductive path between the first capacitive device (120) and the potential source.

Abstract: Disclosed is a system and method for providing backward compatible transmitter diversity in an orthogonal frequency division modulated (OFDM) communication system. According to one aspect of the invention, a method for providing backward compatible transmitter diversity includes the steps of: receiving an input data bit stream; transforming it into an OFDM symbol stream comprised of even and odd symbols; dividing the OFDM symbol stream into a first symbol sub-stream and a second symbol sub-stream; processing the first symbol sub-stream by a first processing block to output a first processed symbol sub-stream; processing the second symbol sub-stream by a second processing block to output a second processed symbol sub-stream; transmitting the first processed symbol sub-stream from a first diversity antenna; and transmitting the second processed symbol sub-stream from a second diversity antenna and both are transmitted over non-overlapping frequencies.

Abstract: The invention relates to an apparatus for reading or writing information on a circular information carrier (D) having a periphery, said apparatus comprising a turntable (501) for clamping and rotating said information carrier (D), said information carrier (D) having an initial tilt from the radial direction of the turntable. The apparatus comprises additional means for applying an end load at the periphery of said information carrier, so as to apply a tilt of known value to said information carrier with respect to the radial direction of the turntable (501), said known value being larger than said initial tilt. The clamping surface of the turntable (501) may be tilted appropriately.

Abstract: A device for scanning a record carrier has a head for scanning a track for reading and/or writing information. A disc scheduler controls receiving requests for accessing the record carrier, the requests including streaming requests regarding real time information and auxiliary requests (44) regarding auxiliary information. The disc scheduler reduces power consumption of the device by switching the scanning means to a stand-by mode when no requests are pending and switching the scanning means to an operational mode when a request has to be executed. The auxiliary requests are executed in a processing interval (45) in combination with a selected one of the streaming requests. Hence the number of spin-ups of the record carrier is reduced.

Abstract: The invention relates to a method of splitting up (220) a stream of audiovisual data into a stream of audio data and a stream of video data and of storing (225) at least the audio data when the content of the stream of audiovisual data matches (210) at least one criterion (215). As additional information, one or few frames of video information may be stored as well so as to provide a user, during reproduction of the audio data, with additional information on the content of the video data stream.

Abstract: The present invention relates to an objective lens actuator comprising a lens holder (10), a first pair of first coil carriers (13,23) fixed on opposite sides of the lens holder, and a second pair of second coil carriers (15,25) adjacent to said first pair and fixed on opposite sides of the lens holder. Said actuator further comprises tension wires (20,21), a tension wire being fixed between the coil carriers of a pair. Use: DVD player/recorder.
