摘要： A method, computer program product, and computing device for obtaining an uncompressed digital media data file. One or more default watermarks is inserted into the uncompressed digital media data file to form a watermarked uncompressed digital media data file. The watermarked uncompressed digital media data file is compressed to form a first watermarked compressed digital media data file. The first watermarked compressed media data file is stored on a storage device. The first watermarked compressed media data file is retrieved from the storage device. The first watermarked compressed digital media data file is modified to associate the first watermarked compressed digital media data file with a transaction identifier to form a second watermarked compressed digital media data file.

摘要： Methods, apparatus, and articles of manufacture for media monitoring are disclosed. In particular, the example methods, apparatus, and articles of manufacture generate signatures. Initially, a first plurality of filtered values are identified by performing a wavelet transform on a first frame of media samples. A first energy value is determined based on a first portion of the first plurality of filtered values, and a second energy value is determined based on a second portion of the first plurality of filtered values. A first descriptor of the first frame of media samples is determined based on a comparison of the first energy value and the second energy value. A first signature is generated based on the first descriptor.
