Selective sending block determination method based on quad-tree structure for live video streaming systems

With the rapid development in internet and video coding technology, applications such as telesurgery and remote operations are becoming more and more popular. In such applications, any delay will significantly lower the performance and may sometimes lead to catastrophic results. As a result, low-delay video streaming is demanded in such applications. Previous works have explored and established several live streaming systems based on fixed size block partitioning. Considering the effectiveness of identifying and extracting regions with similar image characteristics using variable sized block partitioning, this paper attempts to propose a live streaming system with variable sized block partitioning utilizing the quad-tree structure for low-delay live video streaming under limited bandwidth.
