Abstract

See full text

The disclosure details methods of measuring the quality of service of received media signals by analyzing digital watermarks embedded in such signals. The quality of a received video or audio signal can thereby be assessed without having the original version of the signal before transmission. Instead, the strength or quality of the embedded digital watermark is analyzed to determine the quality of the received signal. The degradation of a watermark signal is used to assess quality of service of signals, such as audio and video. Several other features and arrangements are also detailed.
