    Abstract: Systems and methods for increasing transmission bandwidth efficiency by the analysis and synthesis of the ultimate components of transmitted content are presented. To implement such a system, a dictionary or database of elemental codewords can be generated from a set of audio clips. Using such a database, a given arbitrary song or other audio file can be expressed as a series of such codewords, where each given codeword in the series is a compressed audio packet that can be used as is, or, for example, can be tagged to be modified to better match the corresponding portion of the original audio file. Each codeword in the database has an index number or unique identifier. For a relatively small number of bits used in a unique ID, e.g. 27-30, several hundreds of millions of codewords can be uniquely identified. By providing the database of codewords to receivers of a broadcast or content delivery system in advance, instead of broadcasting or streaming the actual compressed audio signal, all that need be transmitted is the series of identifiers along with any modification instructions to the identified codewords. After reception, intelligence on the receiver having access to a locally stored copy of the dictionary can reconstruct the original audio clip by accessing the codewords via the received IDs, modify them as instructed by the modification instructions, further modify the codewords either individually or in groups using the audio profile of the original audio file (also sent by the encoder) and play back a generated sequence of phase corrected codewords and modified codewords as instructed. In exemplary embodiments of the present invention, such modification can extend into neighboring codewords, and can utilize either or both (i) cross correlation based time alignment and (ii) phase continuity between harmonics, to achieve higher fidelity to the original audio clip.

    Abstract translation: 提出了通过分析和综合传输内容的最终组件来提高传输带宽效率的系统和方法。 为了实现这样的系统,可以从一组音频剪辑生成元素码字的字典或数据库。 使用这样的数据库,给定的任意歌曲或其他音频文件可以表示为一系列这样的码字,其中系列中的每个给定码字是可以原样使用的压缩音频分组,或者例如可以被标记 被修改以更好地匹配原始音频文件的相应部分。 数据库中的每个码字具有索引号或唯一标识符。 对于在唯一ID中使用的相对较少数量的比特,例如, 27-30,可以唯一地识别数亿个码字。 通过提前将码字数据库提供给广播或内容传送系统的接收者,代替广播或流式传输实际的压缩音频信号,所有需要发送的信息都是与所识别的码字的任何修改指令一连串的标识符。 在接收之后,具有访问本地存储的字典副本的接收机上的智能可以通过经由接收到的ID访问码字来重构原始音频剪辑,按照修改指令的指示对其进行修改,进一步单独地或以组的形式修改码字 使用原始音频文件(也由编码器发送)的音频简档,并按照指示播放生成的相位校正码字序列和修改后的码字。 在本发明的示例性实施例中,这种修改可以延伸到相邻码字中,并且可以利用(i)基于互相关的时间对准中的一个或两者,以及(ii)谐波之间的相位连续性,以实现对原始音频剪辑的更高保真度。
