How they can be so fast?

[maloxi]

hello guys,
i was wondering how it is possible to retrieve informations about movies so fast.
an example:

Genre: Brutal Death Metal | Length: 01:46:03 | Language: English

or

Inside The Space Station (2004) 720p HDTVRip AVC AC3-CMEGroup
Video: MKV 1280x720 (16 / 9), 25.000 fps, ~ 5200 Kbps | ~ 47 min | 1.93 GB + 5%
Audio 1: Russian, AC-3, 384 Kbps, 6 Ch, Front: LCR, Surround: LR, LFE
Audio 2: English, AC-3, 384 Kbps, 6 Ch, Front: LCR, Surround: LR, LFE
