Original means the box will output the original source provided the hdmi connection reports it as supported. Some TV's do not report 576i as a supported format hence only 576p is reported.
In this case SD is reported as 576p rather than 576i, all HD sources either 1440 x 1080 or 1920 x 1080 as 1080i
