Details about which Samsung TVs will be compliant with the new service have yet to be disclosed. The first of its kind in the pay-TV universe, DirecTV's new video on demand 4K service is something of a testing ground for the company's planned launch of a handful of live 4K channels, slated for rollout in 2015. The plans for the more robust service next year were disclosed by DirecTV CEO Mike White during the company's third quarter earnings call, as reported by Multichannel News.
