Hello Bob,

The question if this use case applies to the task force is a fundamental question. My intention with the use case is to provide the control of the media, something that I do not see completely resolved by video tag. Some of the use cases do refer to <video> so the question is if those should be moved as well (ex. Issue-17, extensions to <video> and <audio> tags.

My only be concern is with timing. To delay discussing the use case until a new TF is created may affect discussions with HTML5 WG. I understand there are pressures to complete HTML5 video tag as soon as possible. I would request if we can discuss the use case and eventually move it to a new TF once it is created.

Best Regards,

While there may be <video> tag requirements imposed by MPEG-2 TS, it doesn't seem to fit within the scope of the HNTF, which is addressing how home network services get discovered and used by Web content.

There has been some discussion about starting a new TF to address how adaptive bit-rate delivery should be accommodated in HTML5. This would seem to be the place to also examine the MPEG-2 TS issue raised.
