Inter-platform streaming multimedia between embedded systems has encountered the problem of head-of-line blocking and non-real-time transmission/receiving. When a mobile device in an embedded system moves between subnets, the node will face the handover problem. In this paper, we utilize stream control transmission protocol (SCTP) features to develop the multimedia communications including streaming multimedia and video/voice over IP based on Linux built in an embedded platform. In SCTP, the multi-homing feature enables the mobile node to handover seamlessly between networks. Also the multi-streaming enables data to be sent in multiple, independent streams in parallel, so that data loss in one stream does not affect the delivery of data in other streams to eliminate head-of-line blocking. Another feature Partially Reliable SCTP (PR-SCTP) is used to achieve the realtime video/audio services.
