ABSTIUCTThe development of new multimedia services and environments requires new concepts both to support the new working process on distributed computers and to protect the multimedia data during the production and the distribution in digital marketplaces.This article addresses copyright protection as a major security demand in digital marketplaces We propose and compare two watermarking techniques for MPEG video with the intention to show the advantages and the possible weakness in the schemes working in the frequency domain and in the spatial domain.To improve the view to the distortion of the watermarked frames we generate a 3D-difference view measuring the changes which were made during watermarking process and/or caused by several damaging attacks. 1.1
