Overlapping clusters: You can split up traffic onto different channels by adding an overlapping cluster.
重叠集群：您可以通过添加重叠集群来将流量划分到不同的通道上。
2
Cluster channels named TO. : This practice works in the limited case that there are no overlapping clusters.
名为TO .的集群通道：此实践在不存在重叠集群的少数情况下有效。
3
The data of overlapped characters and pictures are stored in the ROM of FPGA, The Times are generated by FPGA inner logic circuit to control the switch of TV channels to finish the overlapping work.
