Abstract

This paper proposes a watermarking method for audio and video signals with editing and/or switching capability on a short time basis, in which watermarked information with error correction coding (ECC) is split into audio and video. Collection of information decoded from both audio and video signals is used to recover the embedded information. According to a simple calculation for a case when the Bose-Chaudhuri-Hocquenghem (BCH) code is placed in both video and audio parts, error correction capability improved by BCH (127, 117) and 10 % for 16 % for BCH (63, 51).
