Apple has reportedly revealed a few more details to TV executives about its Apple TV efforts, discussing things like a voice- and movement-controlled interface, and the ability for new devices to pick up a video stream where the user left off on another device. This comes via a source speaking to the Wall Street Journal, which notes that while Apple has indeed been working on a television prototype, these services could already be implemented as part of the current Apple TV.
According to the WSJ's sources, Apple has approached TV execs with these features but has not gone into detail about what technologies or operating systems would be involved, save for AirPlay (the way Apple currently allows iOS devices to stream audio and video to the Apple TV). The deliberations appear to be mostly around strategy and not specific devices—the article acknowledges former Apple CEO Steve Jobs' vision for am Internet-connected TV, but didn't discuss it further except to note that one source said these services can be done with existing Apple technologies. You can color us skeptical that an Apple-branded television set will hit the shelves anytime soon, but it makes sense that Apple is fleshing out its Apple TV offerings in order to better compete with regular television.
