Abstract: The reflective display panel (1), arranged to modulate ambient light for displaying an image, has a pixel (2) and a controller (10,11,100). For the panel (1) to be able to display an image having a flexibly adjusted perceived brightness, the controller (10,11,100) is arranged for providing the pixel (2) with a brightness corresponding to image content and depending on a condition of the ambient light for displaying the image.

Abstract: A device (1) is arranged for controlling the sound levels of a group of audio channels including a user selected main channel (MC) and at least one auxiliary channel (AC1; AC2). The audio channels can be rendered simultaneously. The device comprises automatic level adjustment means (12, 13) for adjusting the sound level of the at least one auxiliary channel relative to the main channel. The level adjustment means (12, 13) may be arranged for adapting the respective sound levels to the content or signal characteristics of each associated audio channel.

Abstract: A method and apparatus (100) for handling a layered digital video stream, comprising a base layer stream and an enhancement layer stream for providing HDTV, is disclosed. Either of the base layer stream or the enhancement layer stream is stored on a hard disc (101), and the other is stored on an optical disc by means of an optical disc drive (102). The streams are handled separately until they are utilized for providing HDTV. When the layered video stream is to be played back with HDTV quality, the base layer stream and the enhancement layer stream are synchronized by means of a synchronizer (106) for referring to the same frame. The synchronized streams are then decoded by means of a base decoder (105a) and an enhancement decoder (105b), which outputs decoded streams that are combined by an adder 112.

Abstract: Apparatus for providing a fluid meniscus with variable configurations by means of electrowetting. A fluid chamber (5) holds two different fluids (A, B) separated by a meniscus (14) of which the edge, having different sides, is constrained by the fluid chamber. A first electrowetting electrode (2a) is arranged to act on a first side of the meniscus edge and a second electrowetting electrode (2a?) is arranged to act separately on a second side of the meniscus edge. Selected meniscus configurations can be formed by providing selected voltages to the first and second electrowetting electrodes respectively.

Abstract: The data representation apparatus (100) for representing data by means of an audio signal (o), contains an processing unit (102) arranged to deliver the audio signal (o) with a characteristic (C) dependent on a positionless data variable (p) capable of having a first value (206) and a second value (208), whereby the data representation apparatus (100) comprises a mapping unit (132), arranged to map by means of a mapping the first value (206) of the data variable (p) to a first position (216) in three-dimensional space, and the second value (208) of the data variable (p) to a second position (218) in three-dimensional space, and the audio processing unit (102) is arranged to change the characteristic (C), resulting in the audio signal appearing to originate from the first position (216) for the data variable (p) having the first value (206) respectively the second position (218) for the data variable (p) having the second value (208), to a user (200) listening to the audio signal (o).

Abstract: The invention relates to a system for processing video signals, the system comprising a receiver (100) arranged to receive video signals, at least one video frame of which comprises at least one area corresponding to a respective one of a plurality of broadcast data sources. The system comprises a processor (150) arranged to process said video frames to extract at least a part of said area from at least one of said video frames. The frame (200) of a mosaic video signal may comprise one or more small pictures (210) and each of them may render a miniature version of a television program. A detection of edges and a detection of lines can be performed for extracting said area (210) or sub-area (240) from the frame. The television channel, from which the extracted area or sub-area was received or with which it is associated, can be identified. The user is enabled to specify a representation of the extracted area or sub-area on a display screen.

Abstract: A motion estimation unit (200, 300) for estimating a motion vector of a group of pixels of an input image (104) comprises an occlusion detection unit (206) for calculating an occlusion map (116) which is applicable to the input image (104); an intermediate motion estimation unit (202) for estimating a first motion vector for the group of pixels based on the input image (104) and a preceding image (102) and a second motion vector for the group of pixels based on the input image (104) and a succeeding image (106); and an assignment unit (204) for assigning, based on the occlusion map (116), a final motion vector as the motion vector, with the final motion vector derived from the first motion vector or the second motion vector.

Abstract: The interpolation unit (400) comprises: a fetching unit (402) for fetching a first value of a first original pixel (114) of a first input image (104), based on a first motion vector (118) applicable to the new pixel (112); a projection unit (404) for projecting a second value of a second original pixel (110) of a second input image (100), based on a second motion vector (116) applicable to the second original pixel (110); and a selection unit (406) for assigning the value of the new pixel (112) by means of comparing the first value with the second value.
