IANAL but I don't think that is quite true. To my knowledge there are no IP issues with the ISO Base Media File Format (ISO/IEC 14496-12) which is one of the more widely used container formats. For "streaming technologies", it is my hope that DASH will be Royalty-Free and some companies have already stated that intention in respect of their IPR. This is a very different state of affairs from codecs such as H.264, for example. ...Mark > So, I'd be surprised if any agreement was reached within the HTML > Working Group on those topics.
