Surely in the Web case the regulatory requirements apply to content providers. Surely there is no regulatory requirement that the captions be DRMed. Also, it doesn't make sense that the content provider could throw anything at the browser and the browser would be responsible by regulation for rendering captions delivered in an unfavorable way. If CDMs and browsers don't support DRMed captions (my reading of the Chromium source code suggests that Chrome with Widevine doesn't and to me that looks like a very reasonable decision), the way content providers can meet the regulatory requirements is that they provide a non-DRMed WebVTT captions to be rendered by the browser without the involvement of the CDM. -- Henri Sivonen hsivonen@iki.fi http://hsivonen.iki.fi/
