Multimedia push-to-talk service in home networks

We propose a distributed Push-to-Talk (PTT) system model to support a one-to-many multimedia content distribution service. We also present a home-monitoring service scenario as an example that demonstrates how a multimedia PTT service can be used in wireless mesh-formed home networks. The proposed system uses wireless mesh routers for a home network. Centralized server-based functionalities for SIP session control and PTT service management are distributed over a set of mesh routers in manner of peer-to-peer system. To realize this service system, the system model and the implementation architecture were proposed and verified by real implementation.
