Abstract: The invention relates to a high-voltage deep depletion transistor, provided in a semiconductor body (1) having a substrate (2) of a first conductivity type, for example the p-type, and a surface layer (3) of the opposite conductivity type, for example the n-type for an n-channel transistor. To prevent formation of inversion layers below the gate, the channel is subdivided into a plurality of sub-channel regions (7a, 7b, 7c, 7d) mutually separated by p-type regions (11a, 11b, 11c, 11d) which serve to remove generated holes. The p-type regions extend across the whole thickness of the channel and are contacted via the substrate. Each sub-channel region may be subdivided further by intermediate p-type regions (13) to improve the removal of holes.

Abstract: A device is disclosed for encoding a stream of databits of a binary source signal (S) into a stream of databits of a binary channel signal (C), wherein the stream of databits of the source signal is divided into n-bit source words (x1, X2), which device comprises converting means (CM) conceived to convert said n-bit source words into corresponding m-bit channel words (Y1, Y2, y3) in accordance with a conversion of the Jacoby type, where m and n are integers, with m>n. The device further comprises control means (10) for carrying out DC-control on said binary channel signal by introducing a freedom of choice in the source-to-channel conversion.

Abstract: A distributed speech recognition system includes at least one client station and a server station connected via a network, such as Internet. The client station includes means for receiving the speech input signal from a user. A speech controller directs at least part of the speech input signal to a local speech recognizer. The, preferably limited, speech recognizer is capable of recognizing at least part of the speech input, for instance a spoken command for starting full recognition. In dependence on the outcome of the recognition, the speech controller selectively directs a part of the speech input signal via the network to the server station. The server station includes means for receiving the speech equivalent signal from the network and a large/huge vocabulary speech recognizer for recognizing the received speech equivalent signal.

Abstract: Real-time information is arranged according to a recording format for playing in standardized players. The information is subdivided into units and playback parameters for reproducing sequences of the units are included in the units. The format prescribes forward pointers to units that are located at a large distance from the unit which includes the forward pointers. However for home recording it is required that a recording is made in one pass, i.e. the video is to be recorded directly at its final location without a large buffer. So the device has a small buffer, and a processing unit for determining pointers to nearby units based on the buffer contents, while values for pointers pointing far forward are set arbitrarily, based on nearby units and/or default values indicating that the unit intended to be pointed to does not exist. Standard playback devices can still play the recorded material in trickplay modes with only minor deviations in the fast forward scanning speed.

Abstract: Recent copy-protection schemes for digital video copy-protection rely on a pixel-watermark together with the presence of a ‘ticket’ to implement the ‘copy-once’ state of content. This ticket is designed to entitle the owner of a disk/tape to making one copy of digital content. We disclose a method to pass along this ticket with the video signal after content has been converted to the analog domain. This form of the ticket is called the analog ticket. The analog signal may be recorded on a legacy device that does not comply with the copy-protection scheme (e.g. ordinary VCRs). The analog ticket is designed such that it is automatically removed in these legacy devices. Next generation copies by compliant devices are made impossible. Three possible ways of embedding the ticket signal into the analog video signal are proposed.

Abstract: The invention describes a filter arrangement as well as an electronic component, each with a bulk acoustic wave resonator unit which is present on a carrier substrate (1). A reflection element (2) is provided between the carrier substrate (1) and the bulk acoustic wave resonator unit for the purpose of acoustic insulation of the generated oscillations. This reflection element (2) may consist either of several layers of alternately high and low impedance or, if the acoustically reflecting substance has a sufficiently low impedance, of a single layer. In addition, a mobile telephone device, a transmitter, a receiver, and a wireless data transmission system as well as a method of manufacturing an electronic component are described.

Abstract: When a program of a certain duration is converted into compressed data (encoded), it is desirable for the total number of data to fit in an available data space, for example, when recorded on an information carrier. More particularly in variable bit rate compression such as a video signal via MPEG-2, this is hard to forecast. For this purpose, a recording device includes a compression unit whose bit rate is influenced by a system controller via a control input during the encoding process depending on the remaining part of the vacant data space on the information carrier and the remaining duration of the program. When parameters that influence the bit rate are set in the compression unit, the system controller will take the complexity of the program derived during a previously encoded part of the program into account. Furthermore, a separate encoding device receives time information and data space information.

Each menu comprises a plurality of menu items which can be selected by a user. With each menu item, a subpicture can be associated. A subpicture is displayed when the cursor touches an associated menu item on screen. Thus, by moving the cursor over the screen, the subpicture dynamically changes so as to display a brief explanation of the menu items.

Abstract: An information stream organized as a sequence of blocks is encoded according to a graceful degradation principle. The stream poses temporal non-uniform data processing requirements. In particular, with respect to a received block one or more blockwise defined control parameters and an associated blockwise processing load are detected (44). Under control (46) of a processing load for one or more previous blocks, one or more later blocks before processing thereof get an adjustment (48) of one or more of the control parameters. This lowers an expected load for the later block in case of an excessive load, and vice versa when detecting a sub-standard load.
