摘要： A method for a machine or group of machines to carry watermark data in an encoded audio data frame of an audio signal includes receiving the encoded audio data frame having encoded therein a portion of the audio signal. The encoded audio data frame includes a plurality of data blocks, wherein the plurality of data blocks includes, a synchronization information block, at least one encoded data block, and an error check block. The method further includes receiving modified watermark data as modified based on a masking threshold analysis of the audio signal and transforming the encoded audio data frame into a modified encoded audio data frame.

摘要： A method for authenticating content via loudness signature includes receiving an input signal comprising a) an audio signal of the content and b) metadata including data indicating remotely measured loudness of the content, measuring loudness of the audio signal of the content to obtain a locally measured loudness of the content, and comparing the remotely measured loudness of the content to the locally measured loudness of the content to obtain an authentication indication based on the comparing.
