4 ASI combiner/splitter function overview
The ASI combiner/splitter can combine and distribute the multiple TS streams using the ASI interface to improve the program distribution network.
The utilization efficiency of the network. After the TS stream passes through the ASI combination and split, the structure, sequence, and bit of the code stream do not change, therefore, ASI
The combiner/splitter can be used not only for multi-channel TS transmission under general conditions, but also for terrestrial digital TV broadcasting single-frequency network.
Streaming requires a stricter program distribution network. The structure of the multi-program distribution network using ASI combiner/splitter is shown in Figure 1. ASI
The code stream structure of the circuit/splitter output is shown in Figure 2.
