What does "data rate" means in digital camera video recording? - data of evangelion

My Canon SX100 IS digital camera offers two options for video recording.

1. Normal Mode
2. LP mode

LP mode, you can record video, two times longer than normal.

I took the path and found the following information when I checked the properties of the video files.

Normal: 14884kbps Data Rate
LP mode: Data Rate 7384kbps

Low quality video data rate not higher data rate then?
