S\u00ed\u0165 pro distribuci obsahu, vytvo\u0159en\u00e1 pomoc\u00ed PeerTube, je zalo\u017eena na propojen\u00ed prohl\u00ed\u017ee\u010d\u016f n\u00e1v\u0161t\u011bvn\u00edk\u016f a vyu\u017e\u00edv\u00e1n\u00ed P2P komunikac\u00ed.

Ka\u017ed\u00fd server s videem funguje jako BitTorrent tracker, kter\u00fd host\u00ed \u00fa\u010dty a videa u\u017eivatel\u016f.
