=== iChat AV 3 ===
In June 2004, [[Steve Jobs]] announced that the next version of iChat AV would be included with [[Mac OS X Tiger|Mac OS X 10.4]].  iChat AV 3 provided additional support to allow up to four people in a single video conference and ten people in an audio conference. Additionally, the new version of iChat used the [[H.264/MPEG-4 AVC|H.264/AVC]] codec, which offered superior quality video compared to the older [[H.263]] codec used in previous versions. This release supported the XMPP protocol, which could be directly used to connect to [[Google Talk]] and indirectly be used to connect to users of services including [[Facebook features#Chat|Facebook Chat]], and [[Yahoo! Messenger]].<ref>{{cite web

In October 2005, iChat received support for encrypted communications, but only for paid subscribers of [[.Mac]] (later [[MobileMe]] and currently [[iCloud]]) service. These features were part of iChat 3.1, released as part of the Mac OS X v10.4.3 update. This version also added support for XMPP multi-user chat.

In March 2007, Apple released the Mac OS X v10.4.9 update, which allowed [[USB video device class]] (UVC) cameras to be used with iChat, rather than FireWire cameras only. This allowed a wider range of cameras to be used with iChat AV.
