Your article gives me the opportunity to highlight a fact that is often overlooked. MPEG standards do not define encoders, but only decoders. Post-processing and display aspects on the decoder are also outside of scope. I will give you two examples to show you how this standard feature of MPEG standards works . This happens because there is room for optimisation in MP3 and MPEG-2 Video encoders that is exploited by smart designers and not exploited by poor designers.
People usually say the opposite.
This is an adequate solution for some business models but not for all. This will provide a more powerful framework enabling the download of arbitrary DRM modules. The particular cost item that remunerates those who have developed Intellectual Property applies to the MPEG standard solution as much as to a proprietary solution. The fact that there is no explicit price tag for the Intellectual Property of proprietary solutions does not mean there there is no cost associated with it, it just means that it is hidden. And this is not necessarily a good feature for a wise buyer.
