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:

As most adaptive streaming application will be over TCP/IP, I would
recommend against using MPEG TS.
MPEG TS is not very space efficient when transported over TCP/IP.
