Abstract: Hashes are short summaries or signatures of data files which can be used to identify the file. Hashing multimedia content (audio, video, images) is difficult because the hash of original content and processed (e.g. compressed) content may differ significantly. The disclosed method generates robust hashes for multimedia content, for example, audio clips. The audio clip is divided (12) into successive (preferably overlapping) frames. For each frame, the frequency spectrum is divided (15) into bands. A robust property of each band (e.g. energy) is computed (16) and represented (17) by a respective hash bit. An audio clip is thus represented by a concatenation of binary hash words, one for each frame. To identify a possibly compressed audio signal, a block of hash words derived therefrom is matched by a computer (20) with a large database (21). Such matching strategies are also disclosed. In an advantageous embodiment, the extraction process also provides information (19) as to which of the hash bits are the least reliable. Flipping these bits considerably improves the speed and performance of the matching process.

Abstract translation: 哈希是数据文件的简短摘要或签名，可用于标识文件。 哈希多媒体内容（音频，视频，图像）是困难的，因为原始内容的哈希和处理（例如压缩的）内容可能会显着不同。 所公开的方法为多媒体内容（例如，音频剪辑）生成鲁棒散列。 音频剪辑被分割成连续的（优选重叠的）帧。 对于每个帧，频谱被分为（15）到频带。 计算每个频带（例如能量）的鲁棒性质（16）并通过相应的散列比特（17）表示。 因此，音频剪辑由二进制散列字的连接表示，每个帧一个。 为了识别可能压缩的音频信号，由计算机（20）与大数据库（21）匹配从其导出的散列字块。 还披露了这种匹配策略。 在有利的实施例中，提取过程还提供关于哪个散列位是最不可靠的信息（19）。 翻转这些位可显着提高匹配过程的速度和性能。

Abstract: A user (102) hears an audio program being broadcast and can record a sample of the audio. The sample is then conveyed to an analyzing means (106) to determine to which broadcast station the user is listening. The analyzing means monitors many broadcast channels. Thus, characteristics of the audio sample and samples taken from the broadcast channels can be compared to find a match. Broadcast information pertaining to the broadcast channel from which the match was found may then be reported back to the user, combined with an advertisement of a promotion, prize notification, discount offers, and other information specific for a certain radio station for example.
