[0070] refer to figure 2 , figure 2 For the first embodiment of the playback fault recovery method under the IPv4 / IPv6 dual-stack environment of the present invention, comprise the following steps:

[0071] Step S110, when the preset requirements are met, extract the domain name of the uniform resource locator, and send A and AAAA domain name resolution requests to the DNS server to obtain the IP address corresponding to the domain name.

[0072] In this embodiment, the dual-stack technology refers to supporting both IPv4 and IPv6 protocols in a system (such as a host or a router). Playback failure refers to the situation where a line fails in both IPV4 and IPV6. Satisfying the preset requirements includes but is not limited to: there is no IP mapping corresponding to the uniform resource locator in the form of a domain name in the IP mapping table, etc., which will be further described in subsequent embodiments.

[0084] In this embodiment, an electronic program guide (electrical program guide, EPG for short) is an English abbreviation of Electronic Program Guide, which means an electronic program menu. The indexing and navigation of various services provided by IPTV are completed through the electronic program guide system. IPTV EPG is actually a portal system of IPTV. The interface of the EPG system is similar to that of a Web page. The EPG interface generally provides various menus, buttons, links and other components that can be directly clicked by the user when selecting a program; the EPG interface can also contain various dynamic or Static multimedia content.

Abstract

The invention discloses a play fault recovery method and device in an IPv4/IPv6 dual-stack environment and a storage medium; the method comprises the following steps: when a preset requirement is satisfied, extracting a domain name of a uniform resource locator, and sending A and AAAA domain name resolution requests to a DNS server to obtain an IP address corresponding to the domain name; receiving and caching IPV4 and IPV6 addresses corresponding to the domain name, and caching the issued port number at the same time; according to the value of the preset priority control parameter, carrying out whether transmission control protocol connection by an IPV4-form address or an IPV6-form address is judged; and when the transmission control protocol connection fails, automatically switching the other connection mode to perform the transmission control protocol connection. The invention solves the problem that the existing set top box terminal cannot be switched to another line in time when the current network is not connected, so that the playing fails and the user experience is influenced.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a playback failure recovery method, device and computer storage medium in an IPv4 / IPv6 dual-stack environment. Background technique [0002] In recent years, the development of IPV6-related technologies and industries is in full swing; the General Office of the Central Committee of the Communist Party of China and the General Office of the State Council have successively issued documents to promote the transformation of the sixth version of the Internet Protocol (IPV6). In response to the national policy call, the Ministry of Industry and Information Technology issued the "Notice on Promoting IPv6 Transformation of Basic Telecom Enterprises' Self-owned Video Playback Service Systems (Draft for Comment)", proposing the IPV6 transformation of the network infrastructure settings of the existing network video broadcast service and the set-top box terminal. need. With the deepening...
