A main stream contains successive content elements of video and/or audio information that encode video and/or audio information at a first data rate. A computation circuit () computes main fingerprints from the successive content elements. A reference stream is received having a second data rate lower than the first data rate. The reference stream defines a sequence of the reference fingerprints. A comparator unit () compares the main fingerprints with the reference fingerprints. The main stream is monitored for the presence of inserted content elements between original content elements, where the original content elements have main fingerprints that match successive reference fingerprints and the inserted content elements have main fingerprints that do not match reference fingerprints. Rendering of inserted content elements to be skipped. In an embodiment when more than one content element matches only one is rendered. In another embodiment matching is used to control zapping to or from the main stream. In another embodiment matching is used to control linking of separately received mark-up information such as subtitles to points in the main stream.

The availability of television channels today may easily be overwhelming for a user and the use of conventional linear zapping when a user switches sequentially between channels arranged in a list as a method of finding interesting content becomes still more inefficient. Thus, a method of automatically determining a channel content for multi-media, audio, and video channels distributed to or acquired by an electronic device is provided, the method comprises the steps of collecting channel data, analyzing the data using statistical methods to determine a channel content, and categorizing the channels into predetermined clusters depending on the channel content. The determination may be made dynamically so that the clusters reflect the specific day and/or time of the day at which the electronic device is used. Also a system for providing such a method is provided.

A lighting device () comprising a base part () with a first magnetic material, and a second part () is disclosed. The second part comprises a light source (), and a nonmagnetic shell () defining an essentially closed cavity, the light source () and the nonmagnetic shell being in a fixed positional relationship, wherein the essentially closed cavity encloses a second magnetic material () displaceable therein. This provides a lighting device () in which the user may readily position the light source () with a large degree of freedom.

Selection of content from a stream of video or audio data

The invention relates to a feeding device () for introducing a piece of linen () to be ironed into an ironing unit by means of suction, the feeding device () being provided with a suction shaft () into which the piece of linen () can be sucked and a top suction portion () which is provided for sucking the piece of linen () into the suction shaft (). The feeding device () comprises a blocking clamp () which is provided to secure the piece of linen () in a clamping position, and which is arranged in the feeding device () in such a way that there is located after the clamping of the piece of linen () a portion of this piece of linen () above this blocking clamp () that can be sucked by the top suction portion () into the suction shaft (). The invention further relates to an ironing device, comprising an ironing unit for ironing a piece of linen () and a feeding unit () for feeding the piece of linen () to be ironed into the ironing unit.

System and method for automatically adjusting a lighting atmosphere based on presence detection

Silences are detected when a local signal power is below a given fixed or relative threshold value, the duration of the local signal power being below the given fixed or relative threshold value is within a first range and at least one of the parameters signal power fall/rise rate and local power deviation falls within a respective further range. The invention further relates to the use of such a silence detection in a receiver ().

Systems and methods for detecting silences in audio signals

Estimating a signal power in a compressed audio signal [A] is provided, the audio signal comprising blocks of quantized samples, a given block being provided with a set of scale factors. The estimating is performed by extracting the set of scale factors from the compressed audio signal, and estimating the signal power in the given block based on a combination of the scale factors. Advantageously, the extracting step and estimating step are performed on only a sub-set of the set of scale factors. The signal power estimation may be used in a silence detector () for use in a receiver ().
