Multimedia download times
The use of multimedia content can assist in making our website more accessible.
When linking to an audio or video file, you will see an indication of the files format and size. The latter is particularly important as large file sizes and associated long download times can make the delivery of multimedia an unwelcome feature.
UK Government guidelines recommend that websites using multimedia files list rough download times for standard file sizes for different modem connection speeds.
However, this can only be taken as a rough guide because download times will be impacted by other factors such as contention ratios (defined as the number of people with whom you share your ISP service connection).
The table below provides rough rule of thumb on download times.
| Modem Speed | Avg. download time for 1mb file |
| 288kb | 6m 04sec |
| 57.6kb | 3m 02sec |
| ISDN (128kb) | 1m 21sec |
| Cable / Dsl (512kb) | 20sec |
