Your digital HDTV antenna would connect to the HDHomeRun device. You will need a computer or other network storage device to record shows. This is not an all-in-one solution like a Tivo or other DVR system. It requires home networking, an HDTV antenna, the device, itself, an annual subscription to record and a local storage location in your home - like a PC or network storage device. It also require Internet access for setup and account management.
