Comcast's X1 entertainment OS is getting a big update which will improve features across the platform's services, and also introduces a slew of new ones to the mix as well. The result will change how you use Comcast services across your TVs, mobiles devices, and computers. Comcast is billboarding the X1's new livestreaming capability that lets you shoot video with a mobile phone in one place and view it on a television somewhere else. The company provides is own hypothetical that certainly makes this sound useful: "Imagine you're in Philadelphia and can live stream your son's tee-ball game to his grandparents' TV in San Francisco," said Marcien Jenckes, Executive Vice President of Consumer Services for Comcast Cable." In terms of features you'll probably use more often, the OS is getting a series of interface and programming tweaks that'll improve user experience.
