The small amount of DVD only releases would have little to no effect on the numbers .. other than perhaps to beef up the DVD totals .. nothing is being released to BD only that I know of ..
"Super Hi-Vision for Public Viewing
NHK R&D and BBC R&D have been working on SHV for a long time and OBS (Olympic Broadcasting Service) came in to help facilitate the capture. The BBC will trial SHV broadcasting, 16-20 times the resolution of existing HD technology. Two SHV cameras, providing 16 times more detail than the average 1080p HD display, will capture the footage. The signals will be recorded on special Panasonic P2 tower machines: Video Signal: 7680x4320/60P; Audio Signal: 22.2ch 24bit; Recording Media: 17 P2 cards X 2 slots; Compression Scheme: AVC-Intra 100x16; File Format: MXF+XML (P2HD)
During the running of the London Olympics, NHK, OBS and the BBC will jointly showcase the Olympics in SVH. Hourly live and pre-recorded 'showcases' will be screened in public venues in Bradford, London and Glasgow and send to Japan and the USA, via private Internet networks, for viewing there. Tickets in the UK will be available for free. The BBC sees SHV very much as an alternative public viewing option for big events like the Olympics."
