Problems solved by technology

[0004] In order to overcome the deficiencies of the above-mentioned prior art, the present invention aims to modify the multicast IP address pool on the multicast transmission switching network by using SDN switching equipment to periodically execute a predetermined IP address change script, thereby solving the problem of modifying the IP address of the signal source server. The workload is heavy and error-prone; and the digital TV conditional reception technology is realized by changing the multicast IP address regularly at high frequency, which can make up for the leakage of the original multicast address, reduce the impact of the multicast address leakage, and increase the risk of criminals. Profit cost and difficulty

Abstract

The invention discloses a method for changing an IPTV (Internet Protocol Television) playing address pool based on an SDN (Software Defined Network) technology. The method comprises the following steps of: adding SDN switching equipment and a multicast IP (Internet Protocol) address change server between a multicast source and a multicast transmission switching network; generating a multicast IP address pool change script according to a user-defined IP change rule, and setting an execution time rule of the script; enabling the multicast IP address change server to execute the script within thespecified time according to the execution time rule, and control the SDN switching equipment to modify the flow table so as to modify the multicast IP address pool; notifying the EPG server to updatemulticast IP addresses corresponding to the channel programs, and issuing a channel list to the set top box; and enabling the network set top box to receive the video signal according to the multicast IP address corresponding to the channel in the channel list. The method can solve the problems that the workload of modifying the IP address of the signal source server is large, and errors are prone to occurring; and the conditional receiving technology of the digital television can be realized by periodically changing the multicast IP address at high frequency.

Description

technical field [0001] The invention relates to the technical field of digital TV network transmission, in particular to a method for regularly and rapidly changing an IP-based digital TV playback address pool through an SDN switching device to realize digital TV conditional reception technology. Background technique [0002] With the advancement of digital TV network transmission technology, most radio and television systems and telecom operators adopt an all-IP TV signal transmission mode. From the input of information sources, signal content processing and scheduling, and signal output broadcast to achieve any point-to-multipoint network connection mode, that is, when a certain network node sends data to a group of network nodes, it does not need to send data to every network node, but only needs to send the data to a specific All network nodes that join the group can receive this data. In this way, for the sender, the data can be sent to all receivers only once, which g...
