You’ll want a broadband connection that’s capable of handling a steady 3 megabits per second for the bulk of Presto’s content – it’s a fairly high bitrate for SD, which explains why it actually upscales reasonably well on a large screen. Most home broadband connections should be more than capable of handling a Presto stream, and the HD content that they’re rolling out is only going to use a little more bandwidth – 4 Mbit/sec.
As with all streaming services, you’ll want to keep an eye on your download cap – unless, of course, your broadband service is with Telstra Bigpond, where Presto streaming is unmetered and unlimited! For everyone else, expect to see Presto’s SD content use about 1.5 GB of your cap for every hour you watch. It’s well worth checking to see if your ISP offers a more generous data allowance or, even better, an unlimited plan.
