Embodiment Construction
[0016] see figure 1 , the present invention is composed of a satellite master station for distributing files and streams and a small station for receiving files and streams in terms of hardware. The hardware system of the present invention includes two parts, a sending end and a receiving end, wherein the sending end transmits the multicast data to the satellite IPE packer through the local area network, goes to the satellite through a modem, and broadcasts downwards with satellite signals. There are two ways for the receiving end. One is to install a satellite receiving card on the receiving computer to directly receive satellite signals, receive files and forward video streams on the receiving computer. The other one uses a satellite receiver to receive the signal, and the machine rebroadcasts the received signal to the local area network, and the computer on the local area network can directly receive the data through the network card. On the transmission layer of the pres...
