摘要： A method and device for transcoding a first audio or video signal represented in one compression format to a second audio or video signal represented in another compression format. The transcoding is performed by direct mapping symbols from the first signal format to symbols of the second signal format. The transcoding can be performed between different formats or between the same format but with different bitrates. Such formats may be MP3 or aac.

摘要： An audio synthesizing apparatus receives an encoded signal comprising a downmix signal and parametric extension data for expanding the downmix signal to a multi- sound source signal. A decomposition processor (205) performs a signal decomposition of the downmix signal to generate at least a first signal component and a second signal component,where the second signal component is at least partially decorrelated with the first signal component. A position processor (207) determines a first spatial position indication for the first signal component in response to the parametric extension data and a binaural processor (211) synthesizes the first signal component based on the first spatial position indication and the second signal component to originate from a different direction. The invention may provide improved spatial experience from e.g. headphones by using a direct synthesis of a main directional signal from the appropriate position rather than as a combination of signals from virtual loudspeaker positions.

摘要： A data stream contains segments with reproducible signal data that has been encoded with a variable length encoding scheme. Each segment also contains first and second information about the length of the signal data in the segment, stored at predetermined relative positions with respect to the start and end of the signal data in the particular segment. During replay access locations are computed for accessing a next succeeding or preceding segment adjacent to a particular segment when a forward and backward direction of replay are selected respectively. The access location is computed from the first information from the particular segment or the second information from the adjacent segment that precedes the particular segment, dependent on whether the forward or backward direction is selected respectively.

摘要： 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.
摘要翻译：本发明提出了一种将辅助数据嵌入到压缩音频信号中的方法。这通过在辅助数据的压缩音频信号的至少一个频率子带中替换最低有效位（LSB）来实现。当用辅助数据替换压缩子带信号的LSB位时，子带信号被有效地修改，导致不同的解码输出。对应于辅助数据的替换的LSB位被作为比特流的一部分传送，并且可以在解码器处容易地提取。以这种方式，解码器获得可用于解码器的更高级音频再现的辅助数据。压缩音频本身保持良好的音频质量，尽管替换频率子带的LSB位，因为LSB位不会对可听见的伪像造成影响。

摘要： The invention relates to a linking unit (100), a parametric encoder (400) and a method for generating linking information L indicating components of consecutive extended segments sp and sc which may be linked together in order to form a sinusoidal track. The segments sp and sc approximate consecutive segments of a sinusoidal audio or speech signal s. The linking unit comprises a calculating unit (120) for generating a similarity matrix S(m,n) in response to received sinusoidal code data and an evaluating unit (140) for receiving and evaluating said similarity matrix S in order to generate said linking information by selecting those pairs of components m,n the similarity of which is maximal. According to the invention the calculating unit (120) is adapted to calculate the similarity matrix S by additionally considering information about the phase consistency between the components of the extended previous segment sp and the extended current segment sc. In that way the selection of components suitable for being linked together is improved resulting in the definition of correct tracks.
