Comcast Chief Executive Brian Roberts teased the idea of streaming-video services such as Netflix and Amazon Prime coming to Comcast, as part of a platform that sounds like the holy grail of home entertainment. In a Q&A session at the Recode technology conference in Palos Verdes, Calif., Roberts said the services could eventually be integrated into what he called “Project Infinity,” a platform that could offer a consumer “any content on any device at any time.” “I hope in a few years they will,” Roberts said about the idea of Netflix and its peers being included. “But we’re not [offering that] today.” For services such as Netflix, getting on Comcast’s video platform would be a coup, as it would instantly increase the potential customer base. Rather than streaming boxes such as an Apple TV or Roku, it could potentially be embedded into the television set-top boxes of the nation’s largest cable provider.
