Devices for encoding and detecting a watermarked signal

Abstract

A method for decoding a signal on an electronic device is described. The method includes receiving a signal. The method also includes extracting a bitstream from the signal. The method further includes performing watermark error checking on the bitstream for multiple frames. The method additionally includes determining whether watermark data is detected based on the watermark error checking. The method also includes decoding the bitstream to obtain a decoded second signal if the watermark data is not detected.

Description

[0001] Related applications [0002] This application is related to, and claims priority to, US Provisional Patent Application No. 61 / 440,332, "ERROR DETECTION FOR WATERMARKING CODECS," filed February 7, 2011. technical field [0003] The present invention generally relates to electronic devices. More particularly, this disclosure relates to means for encoding and detecting watermarked signals. Background technique [0004] The use of electronic devices has become common over the past few decades. In particular, advances in electronic technology have reduced the cost of increasingly complex and useful electronic devices. Cost reductions and consumer demands have proliferated the use of electronic devices, making them nearly ubiquitous in modern society. As the use of electronic devices has expanded, so has the demand for new and improved features of electronic devices. More specifically, electronic devices that perform functions faster, more efficiently, or have higher ...
