Actually, that link takes you to an HDMI-DVI cable. That specific cable won't work with your Apple TV properly. The simple reason is because your TV probably doesn't support DVI, which is a competitive digital video input system. There are other reasons, like DVI doesn't transmit audio (although the AppleTV's optical audio connection fixes that if you've got a 5.1 surround system, but that can get complex if you haven't done the research -- and that would require another cable, too).
That said, Monoprice.com is a good site for buying HDMI cables. Here's a Monoprice HDMI cable
designed to connect an AppleTV to HDTV sets. That link is for a "male to male" cable. The "male" plugs are the ones used in all HDTVs, BluRay players, HD cable and satellite set-top boxes, the Apple TV, and other set-top electronics. For anything that will remain in a house, a male to male cable is fine.
Portable electronics, like video-capable digital SLR cameras, have "female" HDMI jacks. These jacks are smaller than the "male" jacks, and therefore allow more room for other types of jacks to fit on compact devices. In such a case, a "male to female" HDMI cable would be required.
