In recent years, the development of IPV 6-related technology and industry has become active; the improvement of the sixth edition of internet protocol (IPV6) is promoted by continuously publishing files in the offices of the common central office and the national offices. In response to the national policy call, the industry and telecommunications department issues a notification (request for an opinion draft) about modification of the IPv6 system of the self-owned video broadcasting service system of the push-based telecommunications enterprise, and demands for network infrastructure of the video broadcasting service of the existing network and IPv6 modification of the set-top box terminal are raised. The technical improvement of the IPV6 of the related equipment is advanced day by day. In the foreseeable future, the set-top terminal will eventually fully support the IPV6 network.

The scheme adopted by the existing product at present: only supporting IPV4 or IPV6 single stack, the set-top terminal needs to obtain URL in IP form when playing video. Namely, when playing video, the EPG server can issue a URL in a designated IP form, the set-top box terminal can acquire the IP and the port of the server by analyzing the URL, and the server is connected with the acquired IP and port.

According to the scheme, under the condition that the set-top box terminal supports the IPV4/IPV6 dual stack, as the EPG can only select to issue one form of IP address of IPV4 or IPV6, the set-top box terminal cannot be switched to another line in time when the current network is not accessible, and further the playing failure can be caused to influence the user experience.

Based on the above structure, an embodiment of the present invention is proposed.

Referring to fig. 2, fig. 2 is a first embodiment of the playing failure recovery method under IPv4/IPv6 dual stack environment of the present invention, including the following steps:

and step S110, when the preset requirement is met, extracting the domain name of the uniform resource locator, and sending an A and AAAA domain name resolution request to the DNS server to acquire the IP address corresponding to the domain name.

In the present embodiment, the dual stack technology refers to a system (e.g., a host or a router) supporting both IPv4 and IPv6 protocols. Play failure refers to a condition where one of the lines IPV4 and IPV6 fails. Meeting preset requirements includes, but is not limited to: the IP mapping table does not have an IP mapping corresponding to a uniform resource locator in the form of a domain name, and so on, which is further described in the following embodiments.

When the preset requirement is met, the set top box terminal extracts a domain name of a Uniform Resource Locator (URL), and wants a DNS server to send an A and AAAA domain name resolution request to acquire an IP address corresponding to the domain name; the A domain name resolution request corresponds to an IPv4 address, and the AAAA domain name resolution request corresponds to an IPv6 address.

And step S120, receiving and caching the IPV4 and IPV6 addresses corresponding to the domain name, and caching the issued port number.

In this embodiment, the set-top box terminal receives and caches the IPV4 and IPV6 addresses corresponding to the DNS server and simultaneously caches the port number corresponding to the IPV4 address and the port number corresponding to the IPV6 address. For example, the address of IPv4 is: 216.27.61.137, corresponding port number 554; the IPv6 has the address of 2001: cdba: 3257:9652 and the corresponding port number of 555; this is only an example, as determined by the particular application.

And S130, judging whether to perform transmission control protocol connection by using an address in an IPV4 form or to perform transmission control protocol connection by using an address in an IPV6 form according to the value of the preset priority control parameter.

In this embodiment, the preset priority control parameters are specifically set by the relevant personnel, for example, in the present invention, the preset priority control parameters are preferably three: priority control parameter (priority), v4priority control parameter (v4priority), v6priority control parameter (v6 priority); the three priority control parameters are used for indicating priority, and the v4priority control parameter corresponds to IPv4 priority; the v6priority control parameter corresponds to IPv6 priority; the priority control parameter takes a value of 4 or 6, and takes precedence in correspondence with IPv4 when taking a value of 4, and takes precedence in correspondence with IPv6 when taking a value of 6; the initial values of the v4priority control parameter and the v6priority control parameter are 0.

The set-top box terminal judges whether an IPv4 form address is used for Transmission Control Protocol (TCP) connection or an IPV6 form address is used for Transmission Control Protocol (TCP) connection according to the value of the preset priority control parameter; for example, it is determined that the IPv6 type address is currently used as a tcp connection according to the value of the preset priority control parameter.

Step S140, when the connection of the transmission control protocol fails, another connection mode is automatically switched to make the connection of the transmission control protocol.

In this embodiment, the connection failure may be understood as connection timeout, that is, connection timeout between the set-top terminal and the server. When the transmission control protocol connection fails, the set-top box terminal automatically switches another connection mode to be the transmission control protocol connection; for example, when the transmission control protocol of the IPv6 address fails, the connection is automatically switched to the transmission control protocol of the IPv4 address.

In the technical scheme provided by this embodiment, when a preset requirement is met, a set-top box terminal extracts a domain name of a uniform resource locator, and sends an a and AAAA domain name resolution request to a DNS server to obtain an IP address corresponding to the domain name; receiving and caching the IPV4 and IPV6 addresses corresponding to the domain name returned by the DNS server, and caching the port number corresponding to the IPv4 address and the port number corresponding to the IPV6 address at the same time; then, judging whether to use an IPV4 form address as a transmission control protocol connection or to use an IPV6 form address as a transmission control protocol connection according to the value of the preset priority control parameter; when the transmission control protocol connection fails, another connection mode is automatically switched to be used for the transmission control protocol connection. Under the condition that the set-top box terminal supports the IPV4/IPV6 double stacks, the double-stack set-top box can be quickly switched to the other network stack when a certain network stack is disconnected to cause a play fault, and the automatic recovery function of the play fault is realized. The situation that IPTV service cannot be normally used due to the fact that the IPV6 network line is not communicated in the using process of the current network user is guaranteed. By using the method, a user does not need to manually designate the set-top box terminal to be connected according to the IPV4 or IPV6 mode in the dual-stack environment, but the set-top box automatically judges whether to use the IPV4 or the IPV6 according to the network condition, so that the user experience is improved, and the robustness of the set-top box terminal is also improved. Therefore, the problem that the user experience is influenced due to playing failure caused by the fact that the existing set top box terminal cannot be switched to another line in time when the current network is not accessible is solved.

Referring to fig. 3, fig. 3 is a second embodiment of the playing failure recovery method under IPv4/IPv6 dual stack environment of the present invention, including:

step S210, receiving a uniform resource locator in the form of a domain name.

In the present embodiment, an Electronic Program Guide (EPG) is an english abbreviation of Electronic Program Guide, and means an Electronic Program menu. Indexing and navigation of the various services provided by IPTV is accomplished through an electronic program guide system. The IPTV EPG is actually a portal system of IPTV. The interface of the EPG system is similar to a Web page, and various menus, buttons, links and other components which can be directly clicked when a user selects a program are generally provided on the EPG interface; the EPG may also include various types of dynamic or static multimedia content on its interface for the user to browse through.

The set-top box terminal is connected to a specified double-stack EPG template, a user clicks a video playing button, the EPG template can send a URL in a domain name form to the set-top box terminal when sending a video source URL, and the terminal starts a video playing process.

And the set-top box terminal receives the uniform resource locator in the form of the domain name issued by the EPG template.

Step S220, searching an IP mapping table, and judging whether the uniform resource locator has corresponding IP mapping.

In this embodiment, the set-top box terminal queries the IP mapping table and determines whether the current URL has a corresponding IP mapping.

Step S270, if the connection between the current IP and the server for the transmission control protocol fails, the preset requirement is met.

In this embodiment, the preset requirement is met if the set-top box terminal fails to perform the tcp connection with the server in the current IP address form.

In the technical scheme provided by the embodiment, a set-top box terminal receives a uniform resource locator in a domain name form issued by an EPG template; inquiring an IP mapping table, and judging whether the current URL has a corresponding IP mapping; searching that the current URL does not have a corresponding IP mapping in the IP mapping table, and then meeting the preset requirement; or if the current URL has the corresponding IP mapping, continuously judging whether the current IP form is the same as the priority indicated by the preset priority control parameter; if the current IP form is different from the priority indicated by the preset priority control parameter, the preset requirement is met; or if the current IP form is the same as the priority indicated by the preset priority control parameter, the set-top box terminal performs transmission control protocol connection with the server in the current IP address form; and if the transmission control protocol connection between the server and the current IP address fails, the preset requirement is met.

In the above embodiment, if the current URL has the corresponding IP mapping, and the current IP form is the same as the priority indicated by the preset priority control parameter, and the set-top box terminal enters the normal video playing process when the transmission control protocol connection with the server in the current IP address form is successful; therefore, when the network is smooth, the DNS request is prevented from being initiated every time the network is played, and for the terminal equipment, the time consumed by the DNS request is shortened; for the platform side, the server pressure is slowed down.

In the above embodiment, after the step of sending an a and AAAA domain name resolution request to the DNS server to obtain the IP address corresponding to the domain name, the method further includes:

when the DNS server returns an IP address of one type, processing according to the playing flow of the single stack;

or when the IP address is not returned, reporting an error according to the playing failure.

In this embodiment, when the DNS server returns an IP address of one type, the set-top terminal performs processing according to the play flow of the single stack; or when the DNS server does not return the IP address, reporting an error according to the playing failure.

In this embodiment, when the tcp connection fails, the playback fails, and the set-top terminal determines that the current socket connection IP is IPv4 or IPv 6.

And S142, when the connection IP is the IPV4, setting the IP and the port number of the service end as an IPV6 address and a corresponding port number, and performing transmission control protocol connection according to the IPV6 address and the corresponding port number.

In this embodiment, when the connection IP is IPV4, the set-top terminal sets the service end IP and the port number as IPV6 address and corresponding port number, and performs tcp connection according to the IPV6 address and corresponding port number.

And step S143, when the connection is successful, setting the v4priority control parameter to 0, adding 1 to the v6priority control parameter, and emptying the cached IPV4 address.

In this embodiment, when the connection is successful, the set-top terminal sets the v4priority control parameter to 0, adds 1 to the v6priority control parameter, and clears the IPV4 address buffered previously.

Or step S144, when the connection IP is IPV6, setting the IP and the port number of the service end as an IPV4 address and a corresponding port number, and performing transmission control protocol connection according to the IPV4 address and the corresponding port number.

In this embodiment, when the connection IP is IPV6, the set-top terminal sets the service end IP and the port number as IPV4 address and corresponding port number, and performs tcp connection according to the IPV4 address and corresponding port number.

And step S145, when the connection is successful, setting the v6priority control parameter to be 0, adding 1 to the v4priority control parameter, and emptying the cached IPV6 address.

In this embodiment, when the connection is successful, the set-top terminal sets the v6priority control parameter to 0, adds 1 to the v4priority control parameter, and clears the IPV6 address buffered previously.

In the technical solution provided in this embodiment, the step of refining step S140 in the first embodiment specifically includes: when the transmission control protocol connection fails, the set-top box terminal judges whether the current socket connection IP is IPv4 or IPv 6; when the connection IP is IPV4, setting the IP and the port number of the service end as an IPV6 address and a corresponding port number, and performing transmission control protocol connection according to the IPV6 address and the corresponding port number; when the connection is successful, setting the v4priority control parameter to 0, adding 1 to the v6priority control parameter, and emptying the cached IPV4 address; or when the connection IP is IPV6, setting the IP and the port number of the service end as an IPV4 address and a corresponding port number, and performing transmission control protocol connection according to the IPV4 address and the corresponding port number; when the connection is successful, the v6priority control parameter is set to 0, the v4priority control parameter is added with 1, and the cached IPV6 address is emptied.

In the above embodiment, the method further includes:

step S410, when the tcp connection fails and the server returns 302 redirection, re-performing socket connection according to the IP address and port returned by the server 302.

In this embodiment, when the tcp connection fails and the server returns 302 redirection, because different IPs are used to request the server, the redirection URL returned by the server is the URL corresponding to the IP format, so that no special processing is required, and only the socket connection needs to be performed again according to the IP address and the port number returned by the server 302.

Step S420, when the socket connection is successful, performing tcp connection.

In this embodiment, after the socket connection is successful, the set-top terminal and the server perform a tcp connection.

In the technical solution provided in this embodiment, when the tcp connection fails and the server returns 302 redirection, the socket connection is performed again according to the IP address and port returned by the server 302; and when the socket connection is successful, the set-top box terminal is connected with the server side through a transmission control protocol.

In the above embodiment, after the step of step S143, or step S145, or step S420, the method further includes:

step S510, when the transmission control protocol is successfully connected, carrying out hypertext transmission protocol interaction.

In this embodiment, when the connection between the set-top box terminal and the server-side transmission control protocol is successful, the hypertext transmission protocol interaction is performed.

And step S520, if the interaction of the hypertext transfer protocol is smooth, the normal video playing process is started.

Step S530, storing the successfully connected IP and domain name in the IP mapping table.

In the technical scheme provided by the embodiment, when the transmission control protocol of the set-top box and the server is successfully connected, the hypertext transmission protocol interaction is carried out; entering a normal video playing flow when the interaction of the hypertext transfer protocol is smooth; and the set-top box terminal stores the successfully connected IP and the domain name into an IP mapping table. And when in subsequent connection, the URL in the domain name form is received, the corresponding IP mapping is arranged in the IP mapping table, and the transmission control protocol connection is directly carried out with the server in the IP form.

The invention also provides a device for recovering the playing fault under the IPv4/IPv6 dual-stack environment, which comprises a memory, a processor and a playing fault recovery program which is stored in the memory and can run on the processor under the IPv4/IPv6 dual-stack environment, wherein the playing fault recovery program under the IPv4/IPv6 dual-stack environment realizes the steps of the playing fault recovery method under the IPv4/IPv6 dual-stack environment when being executed by the processor.
