[foms] MPEG TS streams and patents

[Jeroen Wijering]

Hello all,

Just to be sure, a transport stream is also a patent encumbered format, correct? So packing up VP8 / Vorbis into TS fragments for adaptive streaming would not be an open solution? It looks like transport streams are part of either the MPEG2 or MPEG2 Systems pool from MPEG-LA. See the PTS/DTS/PAT/PMT references:

Thinking forward, would this mean MPEG DASH is also a no-go as an adaptive streaming standard? It seems to rely heavily on TS / MP4 / AVC. In turn, DASH might also be folded into one of the MPEG LA pools. Does anybody know more about this?

Kind regards,

Jeroen
