H.264 and VC-1 are not part of E-VSB. They are being considered by the ATSC separately. No manufacturer was showing any E-VSB transmission gear, and no manufacturer was showing E-VSB reception gear. In fact I argued to the PBS engineering committee not to vote to approve E-VSB until H.264/AVC and AAC were included.
