An EPG (Electronic Program Guide) system and a video system of a conventional IPTV are deployed in a private network, but new services such as voice control and multi-screen interaction are deployed in a public network. How to enable an application program to access both an IPTV private network and a public network is a problem to be urgently solved in the industry.
Under the condition that a plurality of EPG server ip addresses and a plurality of video server ip addresses deployed in an IPTV system private network are known, a gateway formulates a routing table according to the server ip addresses. The set-top box receives the routing table and acquires double ip addresses (the IP address of the local area network and the IP address of the IPTV private network). And obtaining a routing table of the set-top box device according to the ip address recorded in the routing table and the ip address obtained by the device. When the set-top box accesses the EPG server and the video server of the IPTV private network, the IP address of the IPTV private network is used for accessing IPTV services according to the rule of the routing table of the set-top box equipment because the destination address is known. When the set-top box accesses other destination addresses, the IP address of the local area network is used for accessing IPTV services, thereby realizing service differentiation. However, in this scheme, it is necessary to know in advance ip addresses of multiple EPG servers and multiple video servers deployed in the private network of the IPTV system, and to send these ip addresses to the set-top box through the gateway, and when the addresses of the EPG servers and the video servers deployed in the private network of the IPTV system are changed or the recording is not complete, the device cannot access the IPTV service.

Further, in the application layer, initializing each control needing communication, then adding a first label to each initialized control of which the network type needing access is a public network, and adding a second label to each initialized control of which the network type needing access is a private network. For example, a webview (web page view) control corresponding to a browser needing to access a private network is set to be 2, and a multi-screen interaction control needing to access a public network is set to be 1.
However, before step S10, step S001 and step S002 may be performed, step S010 to step S030 may be performed, or step S001 to step S002 may be performed together with step S010 to step S030.
