A proxy technique for media content sharing among UPnP-enabled home networks
HyunRyong Lee, JongWon Kim · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2005
We propose a proxy-based scheme for segment-based distributed streaming services among UPnP(universal plug and play)-enabled home networks. We design a "SHARE" module that extends HG (home gateway) with a UPnP-compatible protocol. By relaying SSDP (simple service discovery protocol) messages defined in the UPnP device architecture, the SHARE module provides connectivity that is needed to control other UPnP devices for streaming services among home networks. To provide the streaming services, the SHARE module tries to coordinate the distribution of streaming loads among multiple senders by using many-to-one distributed streaming service. It also tries to minimize the quality degradation of streaming services based on the system and network resource status of each sender by leveraging the UPnP QoS services. That is, pre-allocation of HG resources according to the UPnP QoS services can be used to improve the quality of streaming services. Based on the UPnP components, the SHARE module provides the transparent content sharing to users. Through design-level verifications and partial implementations of the proposed SHARE module, we validate the feasibility of our work.
