| 20110311063 | EMBEDDING AND EXTRACTING ANCILLARY DATA - The invention proposes a method for embedding an ancillary data into a compressed audio signal. This is achieved by replacing Least Significant Bits (LSBs) in at least one frequency subband of the compressed audio signal by the ancillary data. When replacing LSB bits of compressed subband signals with the ancillary data, the subband signal is effectively modified, resulting in a different decoded output. The replaced LSB bits corresponding to the ancillary data are conveyed as part of the bitstream and can be easily extracted at the decoder. In such a way the decoder obtains the ancillary data that can be used for more advanced audio reproduction at the decoder. The compressed audio itself maintains a good audio quality despite the replacement of the LSB bits of the frequency subband, because the LSB bits do not contribute to the audible artefacts. | 12-22-2011 |

| 20080250913 | Sound Synthesis - A device for synthesizing sound having sinusoidal components includes a selector for selecting a limited number of the sinusoidal components from each of a number of frequency bands using a perceptual relevance value. The device further includes a synthesizer for synthesizing the selected sinusoidal components only. The frequency bands may be ERE based. The perceptual relevance value may involve the amplitude of the respective sinusoidal component, and/or the envelope of the respective channel. | 10-16-2008 |

| 20100302794 | CAR LIGHTING UNIT FOR GENERATING A BEAM OF LIGHT AND A HOLOGRAPHIC 3D IMAGE - The invention provides a car lighting unit comprising a reflector and a light source arranged to generate light. The reflector circumferentially surrounds the light source and has a reflector opening. The reflector is arranged to reflect at least part of the light from the light source through the reflector opening. The car lighting unit further comprises a source-related 3D hologram and a source-unrelated 3D hologram. The car lighting unit is 5 constructed to generate a beam of light and a source-related holographic 3D image, using light from the light source, during operation of the lighting unit, and a source-unrelated 3D holographic image when the lighting unit is not in operation. | 12-02-2010 |

| 20110013790 | Apparatus and Method for Multi-Channel Parameter Transformation - A parameter transformer generates level parameters, indicating an energy relation between a first and a second audio channel of a multi-channel audio signal associated to a multi-channel loudspeaker configuration. The level parameter are generated based on object parameters for a plurality of audio objects associated to a down-mix channel, which is generated using object audio signals associated to the audio objects. The object parameters have an energy parameter indicating an energy of the object audio signal. To derive the coherence and the level parameters, a parameter generator is used, which combines the energy parameter and object rendering parameters, which depend on a desired rendering configuration. | 01-20-2011 |
| 20110235810 | APPARATUS AND METHOD FOR GENERATING A MULTI-CHANNEL SYNTHESIZER CONTROL SIGNAL, MULTI-CHANNEL SYNTHESIZER, METHOD OF GENERATING AN OUTPUT SIGNAL FROM AN INPUT SIGNAL AND MACHINE-READABLE STORAGE MEDIUM - An apparatus and a method for generating a multi-channel synthesizer control signal, a multi-channel synthesizer, a method of generating an output signal from an input signal and a machine-readable storage medium are provided. On an encoder-side, a multi-channel input signal is analyzed for obtaining smoothing control information, which is to be used by a decoder-side multi-channel synthesis for smoothing quantized transmitted parameters or values derived from the quantized transmitted parameters for providing an improved subjective audio quality in particular for slowly moving point sources and rapidly moving point sources having tonal material such as fast moving sinusoids. | 09-29-2011 |
