                         Initially, we discuss how previous results on the unsuitability of 
                         the current adopted business model for the e-commerce of digital 
                         items affects VOD services. Then, we propose a reversible 
                         degradation method in order to address the lack of an accurate 
                         item validation step in current e-commerce implementations, thus 
                         providing robustness against mistaken purchases; the proposed 
                         method exploits the Scalable Video Coding (SVC) extension of the 
                         H.264/AVC standard. Finally, we illustrate how the proposed 
                         validation method can be used as a component for fair exchange 
                         protocol design, with the purpose of enabling unambiguous dispute 
                         resolution for unsatisfied buyers.",
