Design and implementation of real time video streaming and ROI transmission system using RTP on an embedded digital signal processing (DSP) platform

摘要

Recently, video streaming has been extensively used for information broadcasting. Availability of improved and enhanced transmission facilities make it possible to use video streaming in fast real time applications. Real time video transmission is widely used in surveillance, conferencing, media broadcasting and applications that include remote assistance. Though a lot of work has already been done in the field of video streaming and many systems are already available, most of them either use a dedicated physical medium for data transmission or rely on general purpose computer systems as servers; which make these systems less efficient and un-suitable for such real time applications that require high speed dedicated video servers. This issue can be resolved by deploying special purpose high speed dedicated embedded processors. In this paper, we present the design and implementation of a real-time video streaming system by using an embedded media processing platform. The system deals with the issues of real-time protocol implementation on captured video and serving it to a client system via Ethernet which plays it in real-time. Further, in this piece of work we also deal with ‘Region of Interest’ (ROI) transmission to improve processing efficiency of the system, which allows video fragmentation and communication together in real-time.
