    摘要: The invention relates to a system for content presentation of content signals such as video signals. A content presentation apparatus comprises a content signal receiver (201) receiving a content signal from a content source (203). The signal is stored in a memory (205). The memory is connected to a content analyser (207) which analyses the content and determines to which category of content this belongs. The apparatus further comprises a user preference profile processor (211) which determines a preferred presentation rate for different categories of content in response to a user input or a previous user behaviour. A playback controller (213) controls the playback of the content by setting the presentation rate to the preferred presentation rate of the user preference profile for the content category identified. Specifically, the invention provides for e.g. a fast forward button which fast forwards through unwanted content but plays at normal rate during user preferred content.

    摘要: The invention relates to a circuit (100) for enhancing a stereo sound signal, represented by a left input signal (L) and a right signal (R). By only using the parts of the left input signal (L) and the right input signal (R) that are not correlated to each other, unwanted stereo enhancement of, for example, dialogs is eliminated. On the other hand, the stereo image of sound effects like explosions will be enhanced. Most movies are properly mixed for this. In one embodiment of the invention, a center signal is generated by averaging the left input signal and the right input signal. The invention relates to a method of enhancing a stereo sound signal. The invention also relates to an apparatus (500) for reproducing sound. The invention further relates to a record carrier (610) comprising a computer-executable code, enabling a computer (620) to perform the method according to the invention

    摘要: An audio reproduction system comprises a transmitter device (1) and a receiver device (2). The transmitter device (1) determines the envelope signal of an audio signal (Vin) of a selected frequency range and transmits the envelope signal (VE) over a communication channel (C). The receiver device (2) combines the received envelope signal (VE) with an oscillator signal (VO) to produce a transducer signal. The communication channel (C) is preferably wireless. The transducer (30) is preferably designed to operate at its resonance frequency so as to achieve maximum efficiency.
