摘要： There are proposed wireless headphones which have at least one electroacoustic transducer for the reproduction of audio signals, a receiver for receiving wirelessly transmitted audio data, an intermediate memory for putting the received audio data into intermediate storage, an audio decoding unit and a control unit. The audio data wirelessly received by the receiver are firstly buffered or put into intermediate storage in the intermediate memory. The control unit controls reading of the compressed audio data stored in the intermediate memory so that said data are passed to the audio decoding unit where the compressed audio data are decoded and then outputted by means of the electroacoustic transducers. Wireless transmission is effected at a higher speed than the reproduction of the stored audio signals.

摘要： The present invention relates to steganographically hiding messages in media signals such as video and audio signals. In one implementation, a method of decoding an encoded media signal to extract a plural-bit auxiliary signal therefrom is provided. The media signal includes a plurality of intervals, with the plural-bit auxiliary signal being steganographically encoded in at least some of the intervals. Once encoded in the media signal the plural-bit auxiliary signal is generally imperceptible to a human observer of the encoded media signal. The encoding includes subtle changes to at least some portions of the media signal to thereby represent the plural-bit auxiliary signal. The method includes receiving the encoded media signal; and decoding the received encoded media signal to extract the plural-bit auxiliary signal therefrom. The decoding analyzes a plurality of intervals of the media signal with greater or lesser confidence in the extracted multi-bit auxiliary data signal being obtained by processing more or less intervals of the encoded media signal, respectively.

摘要： A method for dynamically arranging DSP tasks. The method comprises receiving an audio bit stream, checking a remaining execution time as the DSP transforms the audio information into spectral information, simplifying the step of transforming the audio information when the DSP detects that the remaining execution time is shorter then a predetermined interval, and skipping one section of the audio information and decoding the remaining section when the execution time is less than a predetermined interval.
