ADSL or faster broadband connections are recommended for streaming on demand content.
Typically the recommended minimum broadband download speed is 1.5 Megabits per second (Mbps). This applies to on demand streaming for Freeview On Demand as well as other popular streaming services.
You can check your download speed at free test sites such as www.speedtest.net and check with your Internet Service Provider (ISP) for how you can improve your download speed if need be.
