Sorry if this was unclear. Do you need more than the name of the operating system (as vouched for by the CDM) to make the inferences you need to make? Or would something less granular be sufficient (e.g. grouping operating systems that run on at least desktops together and operating systems that run at least on phones together and letting tablets fall into either category depending on their lineage: Windows 8 tablets to the former group and Android tablets to the latter group)? Or is it only a matter of whether the system is considered to be a TV (set top box connected to a TV) or not (e.g. Mac Mini that might be connected to a TV anyway)? -- Henri Sivonen hsivonen@iki.fi http://hsivonen.iki.fi/
