藍光光碟
Although AVCHD shares many format similarities with Blu-ray Disc, it is not part of the Blu-ray Disc specification. Consequently, AVCHD-playback is not universally supported across Blu-ray Disc players. Blu-ray Disc players with "AVCHD" logo play AVCHD discs authored either on 8 cm or 12 cm DVDs. Players without such a logo are not guaranteed to play AVCHD discs.
