Uncompressed HD Video Transport System with Real-time Playout

摘要

This paper presents a cost-effective realization of uncompressed HD (high definition) video transport system over highspeed IP network. This transport system is motivated by the emergence of wide-area high-speed optical networks, where up to 10Gbps can be achieved. The uncompressed version of HD (commonly referred as HDTV) video requires around 1.5Gbps and thus it is really challenging to transport this huge-size uncompressed HD video contents in real-time. Also, it allows us to maintain ultra-high quality with low-latency visualization, since the time and resource consuming encoding/decoding processes are eliminated. Thus, in order to support an interactive video-based collaboration environment with ultimate HD video quality, we have designed and implemented a flexible HD video transport prototype system. Finally, the experiments conducted with the prototype system highlight the possibility of the proposed implementation, in addition to the performance bottlenecks and remaining tasks to be refined and completed.
