said by pb2k:For the time being, H.265 will be of far more use in internet video. I wouldn't expect to see any cable/sat/iptv deployments for upwards of a decade.
Having to buy new encoders on the backend and roll out new STBs or users upgrading TVs is a lot of work and would take forever. cable/sat providers need to finish converting to H.264 from MPEG-2 first before even thinking about H.265 at all; not that they will any time soon.
