The Apple Events channel should automatically appear on the home screen, but if you haven't yet seen it, a quick restart of your Apple TV box should prompt it to show up. Once visible, you should be able to watch the proceedings from the Yerba Buena Center in San Francisco, which kick off at 10am PT (1pm ET).
