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.

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

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.

The invention relates to a method of providing a video signal for display of a stream of video data (200) at a rate other than real-time, the video data being built up from frames, the method comprising the step of real-time rendering of non-contiguous segments of the stream of video data comprising multiple subsequent frames to a first rendered stream; wherein the method further comprises the step of non real-time rendering of the stream of video data by rendering pre-determined non subsequent frames at a speed other than realtime to a second rendered stream; multiplexing the first rendered stream and the second rendered stream for simultaneous display on a display device (150), wherein: the first rendered stream is displayed on a first part (310) of the display device; and the second rendered stream is displayed on a second part (320) of the display device.
摘要:
Disclosed is a method of encoding a multichannel signal, such as a stereophonic audio signal, including at least a first signal component (L) and a second signal component (R). The method comprises the steps of transforming at least the first and second signal components by a predetermined transformation into a principal signal (y) including most of the signal energy and at least one residual signal (r) including less energy than the principal signal, the predetermined transformation being parameterised by at least one transformation parameter (( ) and representing the multichannel signal at least by the principal signal and the transformation parameter. Further disclosed are a corresponding arrangement for encoding a multichannel signals and a corresponding method and arrangement for decoding such a signal.
