Abstract
A system, method, and media edge proxy, MEP, () for providing media data such as Internet Protocol Television, IPTV, or Internet radio channels to a media client (). The MEP obtains the media data from a media server () utilizing a temporary unicast connection and provides the media data obtained from the server to the media client for an initial time period. Upon determining that the initial time period has expired, the MEP obtains the media data via multicast from a multicast router (), provides the media data obtained from the router to the media client, and releases the temporary unicast connection. The invention reduces channel switching delay and thus improves quality-of-experience for the end-user. The invention also avoids excessive IGMP JOIN/LEAVE signaling when a user switches quickly through channels.
