Abstract: A complete automatic sprite generation system uses first-order prediction for an initial estimation, delayed elimination for outlier rejection, and field-based sprite generation for an interlaced source. Optionally, higher-order prediction for the initial estimation may be used to handle more complicated motion. The invention is useful for generating sprites, e.g., for 3D sequences, stock tickers, interactive advertising and other uses. The invention addresses outlier and fast motion problems that are not handled by the existing MPEG-4 scheme. Automatic sprite generation is provided by performing shot detection (e.g., panning or zooming) on the input images to provide a group of successive images that share a common scene for use in forming a sprite. The initial estimation of motion parameter data for forming the sprite is improved by using the motion parameter data of at least two previous input images.

Abstract: A rate control system suitable for use with a digital video transcoder, such as one conforming to the MPEG standard. The proposed rate control system starts coding with any reasonable set of assumed Group of Pictures (GOP) parameters, thereby avoiding a processing delay of about one GOP which would otherwise be incurred to extract the complete GOP structure information from a pre-compressed bit stream. In addition, the system avoids the need to store the data corresponding to the GOP, thereby reducing the memory required for transcoding. Encoding of a first picture in a sequence or GOP begins without a priori knowledge of the picture type of subsequent pictures. A reasonable set of GOP parameters is assumed to determine an encoding bit budget. The bit budget is gradually corrected as successive pictures are coded according to their picture types. Changes in the GOP structure of pre-compressed bitstreams can be addressed, for example, when switching channels, inserting commercials, and the like.

Abstract: An anti-jam bezel is provided for dispensing a flexible substrate from an output slot. The output slot has a front portion for outputting the flexible substrate and a rear portion for receiving the flexible substrate from a transport. A guideway diverges away from the rear portion of the output slot toward the transport to provide a substrate receiving opening. When in use, the bezel body is mounted adjacent the transport with a cavity between the transport and the rear portion of the output slot. The guideway is adapted to catch a leading edge of the substrate exiting the transport, and guide the leading edge to the output slot. In the event the output slot is blocked, the guideway will guide at least a portion of the substrate into the cavity, thereby preventing a jam.

Abstract: In order to provide a screw compressor comprising two screw rotors which are disposed in screw rotor bores in a compressor casing and which compress a refrigerant entering at a refrigerant inlet and discharge it at a refrigerant outlet, and comprising an inlet provided in the compressor casing for refrigerant which is coming from a subcooling circuit and is passed to the inlet in a system of lines, the inlet being disposed in such a way that it opens out into compression spaces enclosed by the screw rotors and screw rotor bores, in which compressor the pressure oscillations or pulsations occurring at the inlet propagate as little as possible to the pipeline system of the subcooling circuit outside the compressor casing, it is proposed that the inlet is preceded by a damper channel which is associated with the system of lines and in which refrigerant from the subcooling circuit is present.

Abstract: Advanced recording options are provided on a personal versatile recorder (PVR) or similar recording device. Television signals and associated electronic programming guide (EPG) data are received at a receiver (30). Recorded program material is stored in a storage device (60). A processor (75) provides for automatic suspending of recording, based on predetermined criteria, for at least a portion of time during which the one or more television programs would otherwise be recorded. Recording may be suspended when non-programming specific content (e.g., a commercial or emergency broadcast) is received at the PVR (20). Non-program specific content can be identified through the use of EPG data or Advanced Television Enhancement Forum (ATVEF) triggers. End of program notifiers may be provided which enable the PVR (20) to record the entire program, regardless of whether the program runs beyond its scheduled time. Recording may be optionally suspended where the program is a rerun.

Abstract: A system for streaming encrypted conditional access (CA) data, such as control words, from a primary or master conditional access provider (CAP) to one or more secondary CAPS. The primary CAP encrypts content (program data) that is to be access-controlled, such as a television program, according to the associated CA data. A first group of user terminals is compatible with the CA data of the primary CAP. The CA data is then provided to the secondary CAPs to provide corresponding CA data for the content in the secondary CAPs' associated formats for compatibility with other groups of terminals. The invention can be used in any packet-based distribution system, including a broadband television network headend, and avoids the need for the secondary CAPs to request the control words on an as-needed basis. Moreover, the CA data for a current crypto-period and a number of future crypto-periods are provided in a “sliding window” to allow the secondary CAP to begin preparing its CA data in advance.

Abstract: The invention relates to a laser amplifier system consisting of a solid body, which comprises a laser-active medium, of a pumping radiation source for generating a pumping radiation field, which repeatedly permeates the solid body, and of a focusing system. Said focusing system generates a number of different branches of the pumping radiation field that enter the solid body and converts at least one branch emerging from the solid body into one of the branches which enter the solid body and which are different from the emerging branch. The aim of the invention is to improve a laser amplifier system of the aforementioned type in order to be able to generate the highest possible pumping power density in the solid body while requiring the smallest possible amount of complexity.

Abstract: A device comprising a number of different wavelength-selective active-layers arranged in a vertical stack, having band-alignment and work-function engineered lateral contacts to said active-layers, consisting of a contact-insulator and a conductor-insulator. Photons of different energies are selectively absorbed in or emitted by the active-layers. Contact means are arranged separately on the lateral sides of each layer or set of layers having the same parameters for extracting charge carriers generated in the photon-absorbing layers and/or injecting charge carriers into the photon-emitting layers. The device can be used for various applications: wavelength-selective multi-spectral solid-state displays, image-sensors, light-valves, light-emitters, etc. It can also be used for multiple-band gap solar-cells. The architecture of the device can be adapted to produce coherent light.

Abstract: Methods and apparatus are provided for modulating a flow of fluid in a duct using a rotating member that rotates in the duct. A sensing unit senses the rotation speed of the rotating member and generates a rotation signal as a function of the sensed rotation speed. A control unit receives the rotation signal from the sensing unit and generates a control signal to modify the rotation speed of the rotating member. The apparatus can be self-powering by generating an electric current in response to rotation of the blade.

Abstract: A system (300, 500) for scrambling digital samples (115, 200, 250, 260, 270) of multimedia data, including audio and video data samples, such that the content of the samples is degraded but still recognizable, or otherwise provided at a desired quality level. The samples may be in any conceivable compressed or uncompressed digital format, including Pulse Code Modulation (PCM) samples, samples in floating point representation, samples in companding schemes (e.g., ?-law and A-law), and other compressed bit streams. The quality level may be associated with a particular signal to noise ratio, or quality level that is determined by objective and/or subjective tests, for example. A number of LSBs can be scrambled in successive samples in successive frames (FRAME A, FRAME B, FRAME C). Moreover, the parameters for scrambling may change from frame to frame. Furthermore, all or part of the scrambling key (310) can be embedded (340) in the scrambled data and recovered at a decoder (400, 600) to be used in descrambling.
