The invention discloses a
local area network system for realizing streaming media switch among peer-to-peer devices and a realization method thereof. The
system comprises a plurality of the peer-to-peer devices, and each peer-to-peer device comprises a service
application module, a device discovery control management module and an application
management support module, wherein the service
application module plays streaming media; the device discovery control management module discovers the peer-to-peer devices on a
local area network and establishes a communication mechanism; and the application
management support module identifies and manages the discovered peer-to-peer devices, and performs service support on the service
application module. In the
system and the method, a first peer-to-peer device which is playing the streaming media sends a streaming media switch request to a second peer-to-peer device in the plurality of the peer-to-peer devices according to the communication mechanism; and the second peer-to-peer device responds the streaming media switch request, sends the streaming media request to an assigned
network address about the streaming media, and receives and plays the requested streaming media. The system and the method realize the switch of streaming media play among various peer-to-peer terminal devices in the
local area network such as a digital home network, and promote user experience.
