An apparatus and a method for driving loudspeakers of a sound system in a vehicle, the system having at least two loudspeakers of a basic system, and a plurality of loudspeakers of a focus system wherein each of the loudspeakers has a position in an environment. The apparatus includes a basic channel provider for providing basic system audio channels for driving the loudspeakers of the basic system and a focused source renderer for providing focus system audio channels to drive the loudspeakers of the focus system. The focused source renderer is configured to calculate a plurality of filter values for the loudspeakers of the focus system based on the positions of the loudspeakers of the focus system and based on a position of a focus point.

A display has a spatial light modulator for dynamically controlling a luminance of each pixel according to an input signal, the spatial light modulator having a non-uniform spatial characteristic, the display also having an optical filter having a spatial pattern to alter the luminance to compensate at least partially for the non-uniform spatial characteristic. An electronic signal processing element applies some precompensation predominantly of higher spatial frequencies for the non-uniform spatial characteristic. Such dynamic and optical compensation can enable tuning for different optimizations or for compensating for variations over time. A backlight has an optical source and an optical filter, the source having a color output which has a non-uniform spatial characteristic, and the optical filter having a spatial pattern to alter the color to compensate in part at least for the non-uniform spatial characteristic.
摘要:
A system and method for connecting a processing device to a functional device connected to or in a base unit of a communications network, the base unit having a transmitter and the processing device having a memory, a display and an operating system. A first peripheral device is adapted to be coupled to the processing device via a generic communications protocol, the first peripheral device having a receiver and at least one fixed or configurable endpoint of the functional device exposed on the first peripheral device. The base unit and the first peripheral device is adapted to transmit and receive data respectively over the communications network from the functional device to the processing device via the at least one fixed or configurable endpoint using the generic communications protocol for communication between the processing device and the first peripheral device.

Means for controlling the computational complexity related to video encoding that includes a dynamic rate distortion cost error threshold and constrains the encoding complexity to a given complexity target. The solution is selective and provides fast convergence while incurring only a limited loss in rate distortion performance.

A method and system of perceptual quantization for providing a linear perceptual quantizing process of an Electro-Optical Transfer Function (EOTF) for converting received digital code words of a video signal into visible light having a luminosity emitted by a display, including a target contrast dependent exponential video coding providing quantized video levels, with which there is a fixed relative increment of luminosity per quantized video level, so that every quantized video level visibly has the same proportional luminosity variation.
摘要:
An audio reproduction system for reproducing audio data of at least one audio object and/or at least one sound source of an acoustic scene in a given environment comprising: at least two audio systems acting distantly apart from each other, wherein one of the audio systems is adapted to reproduce the audio object and/or the sound source in a first distance range to a listener and another of the audio systems is adapted to reproduce the audio object and/or the sound source in a second distance range to the listener, wherein the first and second distance ranges are different and possibly spaced apart from each other or placed adjacent to each other; and a panning information provider adapted to process at least one input to generate at least one panning information for each audio system to drive the at least two audio systems.

Seamless display screens that are portable and can be installed in a fast manner, as well as a projection unit for use with several projectors as well as methods of making such display screens. The projection unit can be suitable for being used as a rear projection unit. Devices are provided for reducing depth of the projection unit, to compensate for blend zones and to make it easy to transport such as to be suitable for trade shows, e.g. mirrors or Fresnel lenses.
摘要:
A method for controlling a three-dimensional multi-layer speaker arrangement having a plurality of speakers arranged in spaced layers. The method includes: providing information for a sound to be played back from a 3D source position assigned to the sound, wherein the source position is defined with respect to a reference point (RP) within the multi-layer speaker arrangement, extracting a 3D source position (SPXY) from the source position and calculating layer specific speaker coefficients using a 2D calculator to position the sound two dimensional source position, and feeding a vertical pan or 3D source position into a multilayer calculator for obtaining a layer gain factor for each layer for obtaining speaker coefficients used as individual gains enabling the speakers to play back the sound.
摘要:
An electronic system having an assembly of a plurality of electronic devices each driven by a local power unit and a power sequencer control circuit for controlling the power on or off operation of the local power units. The electronic devices can be for example display units of a display wall. An advantage of such an assembly, e.g. a tiled display or display wall, is that a low level or as little energy as possible is dissipated by the local power units such as DC power supplies associated with the electronic devices, e.g. tiles of a display, and the associated “housekeeping” electronics. A further advantage is a limitation of the inrush current at start-up.
