Various steps of a method for implementing multi-screen interaction in an exemplary embodiment of the present disclosure will be described in more detail below with reference to the accompanying drawings and embodiments.

FIG. 2 illustrates a flow chart of a method of implementing multi-screen interaction in accordance with one embodiment of the present disclosure. The method provided by the embodiment of the present disclosure may be performed by a multi-screen interactive proxy service application in the bandwidth access server BRAS 101 as shown in fig. 1. In some practical applications, the multi-screen interactive proxy service application may provide DLNA (DIGITAL LIVING NETWORK ALLIANCE) protocol services, for example, the multi-screen interactive proxy service application may provide services such as NETWORK interconnection, NETWORK protocol, media transmission, discovery control and management of devices, and so on. The present disclosure is not limited thereto.

In the following illustration, an execution subject is illustrated with a multi-screen interactive proxy service application deployed on broadband access server BRAS 101.

As shown in fig. 2, the method for implementing multi-screen interaction provided by the embodiment of the disclosure may include the following steps:

step S201, receiving a multi-screen interaction control command for a multi-screen interaction service sent by a target user equipment UE through a public network.

The target UE may be a wide area network terminal, such as a smart phone, a tablet computer, a notebook computer, or the like, and may send a request to a multi-screen interactive proxy service application deployed on a BRAS through a public network (also referred to as a wide area network). For example, the multi-screen interaction control command may be sent to the multi-screen interaction proxy service application through an APP (e.g., multi-screen interaction APP) for multi-screen interaction service pre-installed on the target UE. In some practical applications, the multi-screen interactive control command may be one of a play command, a pause command, a fast forward command, and a fast reverse command, or may be other commands for multi-screen interactive control, which is not limited in this disclosure.

Step S203, based on the multi-screen interaction control command, inquiring the network connection information group for the multi-screen interaction service to perform IP address conversion, and obtaining the private network IP address and the multi-screen interaction port number for the multi-screen interaction service. Wherein, the network connection information group may include: an IPTV service account number, a private network IP address, a public network IP address and a multi-screen interactive port number which have association relation. In some implementations, the multi-screen interactive proxy service application may maintain one or more network connection information sets to interface with different terminals.

In some embodiments, step S203 may further include: determining a port number for receiving a multi-screen interaction control command as a multi-screen interaction port number; and inquiring the network connection information group to obtain the private network IP address corresponding to the multi-screen interactive port number.

The multi-screen interaction APP on the target UE can send a network request data packet corresponding to the multi-screen interaction control command to the multi-screen interaction proxy service application, the multi-screen interaction proxy service application can determine a multi-screen interaction port number according to the network request data packet, and a corresponding private network IP address is obtained by inquiring a pre-stored network connection information set.

Step S205, a target IPTV set top box for the multi-screen interactive service is determined according to the private network IP address, and a target port of the target IPTV set top box for the multi-screen interactive service is determined according to the multi-screen interactive port number.

The private network IP address may be used to determine a target IPTV set-top box for implementing the multi-screen interactive service, and the target port corresponding to the multi-screen interactive port number may be used to determine a specific program for implementing the multi-screen interactive service in the target IPTV set-top box. In some practical applications, the private network IP address and the multi-screen interactive port number may be allocated to the target IPTV set-top box by the multi-screen interactive proxy service application after the target IPTV set-top box performs IPTV dialing.

In this embodiment, the terminal and the multi-screen interactive proxy service application may communicate through the public network, and after the IP address conversion is performed by the multi-screen interactive proxy service application, a private network IP address and a multi-screen interactive port number for the multi-screen interactive service may be obtained, where the private network IP address and the multi-screen interactive port number may be used to determine a target IPTV set-top box corresponding to the same multi-screen interactive service and a functional program thereon, so that after the IP address conversion in this embodiment, a network data forwarding route of "terminal-public network-multi-screen interactive proxy service application-private network-IPTV set-top box" may be determined.

Step S207, the multi-screen interaction control command is forwarded to the target port of the target IPTV set-top box through the private network.

In the network data forwarding route of the terminal-public network-multi-screen interaction proxy service application-private network-IPTV set top box, the terminal-public network-multi-screen interaction proxy service application can enable the terminal to send and receive multi-screen interaction service data (such as control commands) through the public network, and the multi-screen interaction proxy service application-private network-IPTV set top box can enable the IPTV set top box to send and receive the multi-screen interaction service data (such as control commands) through the private network; therefore, in the method for realizing the multi-screen interaction provided by the disclosure, the risk of the IPTV platform being exposed in the public network is avoided in the process of realizing the IPTV cross-network multi-screen interaction, and in the step, the IPTV cross-network multi-screen interaction is realized and the safety isolation of the IPTV private network and the public network is ensured.

Through the embodiment, the multi-screen interaction proxy service application such as DLNA can be provided on the BRAS, the public network connection for multi-screen interaction is maintained on the BRAS, the public network IP address, the multi-screen interaction port and the private network IP address and the multi-screen interaction port of the target IPTV set top box are bound, then the multi-screen interaction control command sent by the wide area network terminal (namely the target UE) is forwarded to the corresponding target IPTV set top box, and a network channel special for multi-screen interaction service is established for the target IPTV set top box.

Fig. 3 is a flowchart illustrating a playing method in the case that the multi-screen interaction control command is a playing command in the implementation method of multi-screen interaction according to an embodiment of the present disclosure, as illustrated in fig. 3, after step S207, the implementation method of multi-screen interaction further includes:

step S301, a media stream acquisition request generated by the target IPTV set-top box based on the play address in the play command is received.

If the multi-screen interactive control command is a play command, the play command may carry play address information of media stream data to be played, after receiving the play command carrying the play address information, the target IPTV set-top box may generate a media stream acquisition request (e.g., a request message containing the play address information) based on the play command, and then receive the media stream acquisition request sent by the target IPTV set-top box through the private network by using the multi-screen interactive proxy service application.

Step S302, a media stream acquisition request is sent to a target UE; and receiving the media stream data acquired and transmitted by the target UE based on the media stream acquisition request.

After receiving the media stream obtaining request, the multi-screen interactive proxy service application can forward the media stream obtaining request to the target UE through the public network, so that the target UE obtains corresponding media stream data based on the play address in the media stream obtaining request, and then the multi-screen interactive proxy service application receives the media stream data transmitted by the target UE through the public network.

Step S303, the media stream data is transmitted to the target IPTV set-top box.

The multi-screen interactive proxy service application transmits the media stream data received from the target UE to the target IPTV set top box through the private network so that the target IPTV set top box decodes and plays based on the media stream data to complete a playing command.

In this embodiment, the data (including the request and the media stream data) can be forwarded between the target UE and the target IPTV set-top box through the multi-screen interactive proxy service application, so that the IPTV cross-network multi-screen interaction is realized, and the safety isolation between the IPTV private network and the public network is ensured.

Before the multi-screen interactive proxy service application forwards the multi-screen interactive control command sent by the target UE, a network data forwarding route, i.e. a "terminal-public network-multi-screen interactive proxy service application-private network-IPTV set-top box" for the multi-screen interactive service, needs to be built, and in some embodiments, a network connection information set may be generated and stored in advance for querying, so as to determine the network data forwarding route.

Fig. 4 is a flowchart illustrating a method for generating a network connection information set in a multi-screen interaction implementation method according to an embodiment of the present disclosure, where, as shown in fig. 4, the multi-screen interaction implementation method provided by the present disclosure may further include:

step S401, determining a private network IP address and a multi-screen interactive port number for allocation to the target IPTV set-top box.

When the target IPTV set-top box sends a dialing request to the BRAS to perform IPTV dialing authentication (for example, an IPTV dialing account can be input at a dialing interface to perform dial networking), the BRAS may allocate a private network IP address for the IPTV service to the target IPTV set-top box. In some implementations, the assigned private network IP address may be different each time the target IPTV set-top box restarts networking.

In addition, the BRAS can maintain a public network connection special for the multi-screen interactive service, and the public network connection comprises a multi-screen interactive port which can be provided, so that the BRAS can allocate an independent multi-screen interactive port number for the multi-screen interactive service to each IPTV set top box.

After the BRAS allocates the private network IP address and the multi-screen interaction port number for the target IPTV set-top box, the private network IP address and the multi-screen interaction port number may be stored in a preset storage space, so that the multi-screen interaction proxy service application deployed on the BRAS reads data from the preset storage space to determine the private network IP address and the multi-screen interaction port number for allocation to the target IPTV set-top box.

In some embodiments, step S401 may further include: acquiring a private network address pool for IPTV service, and determining a private network IP address for being distributed to a target IPTV set top box from the private network address pool; and acquiring public network connection information for the multi-screen interactive service, and determining a multi-screen interactive port number for being distributed to the target IPTV set top box according to the public network connection information.

The IPTV platform can plan an IP address pool in advance for the IPTV set top box to use, and when the IPTV set top box performs IPTV dialing authentication, the BRAS or the multi-screen interactive proxy service application deployed on the BRAS can determine a private network IP address from the address pool special for the IPTV to be distributed to the target IPTV set top box. And the BRAS or the multi-screen interactive proxy service application deployed on the BRAS can acquire public network connection information for the multi-screen interactive service maintained on the BRAS, so as to determine a multi-screen interactive port number for distribution to the target IPTV set top box.

Step S403, determining an IPTV service account according to the IPTV dial-up account of the target IPTV set-top box, and obtaining a public network IP address for the multi-screen interactive service.

The IPTV dialing account of the target IPTV set-top box may be information input when the target IPTV set-top box performs IPTV dialing authentication on the BRAS, and in some practical applications, the IPTV dialing account and the IPTV service account may be different but may have an association relationship, for example, IPTV in xx province, the service account is abcdefg, and the dialing account may be abcdefg@iptv.xx, so that the IPTV service account may be determined according to the IPTV dialing account. In addition, the public network connection which is maintained on the BRAS and is special for the multi-screen interactive service can also contain a public network IP address, so that the multi-screen interactive proxy service application can acquire the public network IP address for the multi-screen interactive service from the public network connection.

It should be noted that, the execution sequence of the step S401 and the step S403 is not limited in this disclosure, the step S401 may be executed first, then the step S403 may be executed first, then the step S401 may be executed, and the step S401 and the step S403 may be executed simultaneously. It is only necessary to ensure that step S401 and step S403 are performed before step S405.

And step S405, the IPTV service account, the private network IP address, the public network IP address and the multi-screen interaction port number are stored in an associated mode, and a network connection information set is generated.

After an IPTV service account number and a private network IP address for an IPTV service and a public network IP address and a multi-screen interaction port number for a multi-screen interaction service are determined, the information is associated, bound and stored to generate a network connection information group, namely, a network data forwarding route of a terminal-public network-multi-screen interaction proxy service application-private network-IPTV set top box for IPTV cross-network multi-screen interaction is established.

In some embodiments, after obtaining the set of network connection information, further comprising: and reporting the network connection information group to a proxy service management platform positioned in the public network.

The data transmission between the proxy service management platform and the BRAS where the multi-screen interactive proxy service application is located can be performed through a CR (Core Router). In some practical applications, the proxy service management platform may correspond to one or more multi-screen interactive proxy service applications, and multiple network connection information groups may be stored in the proxy service management platform, so as to facilitate unified management and query of information.

Fig. 5 shows a flowchart of a method for implementing multi-screen interaction according to yet another embodiment of the present disclosure. The method provided by the embodiments of the present disclosure may be performed by the terminal 103 as shown in fig. 1. The present disclosure is not limited thereto.

In the following illustration, the target UE is exemplified as an execution subject.

As shown in fig. 5, the method for implementing multi-screen interaction provided by the embodiment of the disclosure may include the following steps:

step S501, determining a multi-screen interactive proxy service application for a multi-screen interactive service; the multi-screen interactive proxy service application is deployed on the BRAS.

When the target UE needs to perform multi-screen interaction, the multi-screen interaction proxy service application serving the local multi-screen interaction service can be determined first, so that data forwarding can be performed through the determined multi-screen interaction proxy service application.

In step S503, the multi-screen interaction control command is sent to the multi-screen interaction proxy service application through the public network, so that the multi-screen interaction proxy service application forwards the multi-screen interaction control command to the target IPTV set-top box for the multi-screen interaction service through the private network.

The target UE and the multi-screen interaction proxy service application can communicate through a public network, and the multi-screen interaction proxy service application and the target IPTV set top box can communicate through a private network, so that the multi-screen interaction proxy service application plays a role in communication isolation, and the IPTV set top box is realized based on an IPTV platform, so that the risk that the IPTV platform is exposed in the public network is avoided in the process of realizing the IPTV cross-network multi-screen interaction in the method for realizing the multi-screen interaction.

Fig. 6 illustrates a flowchart of determining a multi-screen interactive proxy service application for a multi-screen interactive service in a multi-screen interactive implementation method according to an embodiment of the present disclosure, as shown in fig. 6, step S501 may further include:

step S601, logging in a multi-screen interactive application program based on an IPTV service account.

In some practical applications, an APP (e.g., a multi-screen interaction APP) for a multi-screen interaction service may be pre-installed on a target UE, and an IPTV service account may be input to log in the APP.

Step S603, sending a service discovery request for multi-screen interactive service to the proxy service management platform through the public network; the service discovery request comprises an IPTV service account.

In some implementations, the APP on the target UE may use the UPnP (Universal Plug and Play ) protocol to discover the corresponding multi-screen interactive proxy service application. Specifically, after successfully logging in the APP on the target UE, the target UE can authenticate to the proxy service management platform through the APP and initiate UPnP discovery to the proxy service management platform; after the proxy service management platform successfully authenticates the target UE, a reply requesting IPTV service account information can be sent to the target UE; and the target UE sends the IPTV service account number of the local machine to the proxy service management platform based on the reply.

Step S605, receiving a public network IP address and a multi-screen interactive port number for the multi-screen interactive service returned by the proxy service management platform in response to the service discovery request; the public network IP address and the multi-screen interaction port number are obtained by the proxy service management platform based on IPTV service account searching.

In some practical applications, the proxy service management platform may pre-store a network connection information set for the multi-screen interactive service, which is reported by the multi-screen interactive proxy service application. After the target UE informs the proxy service management platform of the IPTV service account, the proxy service management platform may query based on the IPTV service account to obtain a network connection information set for the multi-screen interactive service of the target UE, and then return the public network IP address and the multi-screen interactive port in the network connection information set to the target UE.

Step S607, determining a multi-screen interactive proxy service application for the multi-screen interactive service according to the public network IP address and the multi-screen interactive port number. The public network IP address and the multi-screen interactive port number can be used for positioning multi-screen interactive proxy service application serving the multi-screen interactive service of the target UE.

In some embodiments, the multi-screen interactive control command includes one of a play command, a pause command, a fast forward command, and a fast reverse command; and in the case that the multi-screen interactive control command is a play command, after the multi-screen interactive control command is sent to the multi-screen interactive proxy service application, the method further includes: receiving a media stream acquisition request sent by a multi-screen interactive proxy service application; the media stream acquisition request is generated by a target IPTV set top box for the multi-screen interactive service based on a play command; acquiring media stream data according to the media stream acquisition request; the media stream data is transmitted to a multi-screen interactive proxy service application.

Through the embodiment, the data (including the request and the media stream data) can be forwarded between the target UE and the target IPTV set top box through the multi-screen interaction proxy service application, so that the IPTV cross-network multi-screen interaction is realized, and the safety isolation of the IPTV private network and the public network is ensured.

Fig. 7 is a schematic diagram of a framework of a method for implementing multi-screen interaction according to an embodiment of the present disclosure, where, as shown in fig. 7, the schematic diagram of the framework of the method for implementing multi-screen interaction includes a target UE701, a BRAS702, a multi-screen interactive proxy service application 703 deployed on the BRAS702, an IPTV set-top box 704, a proxy service management platform 705, and an IPTV platform 706. In fig. 7, data communication may be performed between a target UE701 and a BRAS702 through a public network, data communication may be performed between the target UE701 and a proxy service management platform 705 through a public network, data communication may be performed between the BRAS702 and the proxy service management platform 705 through a first CR (core router) in the public network, data communication may be performed between an IPTV set-top box 704 and the BRAS702 through a home gateway, and data communication may be performed between the BRAS702 and an IPTV platform 706 through a second CR (core router) in the public network; the proxy service management platform 705 is located in a wide area network (public network), and the IPTV platform 706 is located in an IPTV private network.

Based on the frame diagram shown in fig. 7, the method for implementing multi-screen interaction according to an embodiment of the disclosure may include the following steps:

step S701, network dialing. The method specifically comprises the following steps: after the IPTV set-top box 704 is powered on, PPPoE private network dialing is performed, so that the BRAS702 allocates an IP address (including a private network IP address and a public network IP address) to the IPTV set-top box 704.

For example, BRAS702 may assign a private network IP address to IPTV set top box 704: 10.22.91.152. in addition, the BRAS702 can also confirm whether the IPTV set-top box 704 has an internet connection; if not, an internet connection (public network connection) dedicated to multi-screen interaction is established, for example, an internet (public network) IP address can be determined: 100.17.18.19. ports for multi-screen interactions may also be determined, e.g., multi-screen interaction port numbers are: 49152. in this step, after the network dialing is successful, the IPTV set-top box 704 can implement the IPTV service based on the IPTV platform 706 through the BRAS 702.

Step S703, IP binding. The method specifically comprises the following steps: the multi-screen interactive proxy service application 703 performs association binding on the public network IP address, the private network IP address, and the multi-screen interactive port number.

For example, the "private network IP address" in step S701 may be: 10.22.91.152"," public network IP address: 100.17.18.19 "and" multi-screen interaction port number: 49152 "do the association binding.

In some practical applications, the above-mentioned association binding may be implemented by an instruction "iptable-t nat-a pre-routing-d 100.17.18.19-p-tcp-dport 49152-j DNAT-to-destination10.22.91.152:49152", where an iptable may be created, and an externally sent network packet destined for the public network IP 100.17.18.19 port 49152 may be forwarded to the internal private network IP10.22.91.152, port 49152, that is, a network packet sent by the target UE701 through the outside (public network) may be forwarded to a corresponding port of the IPTV set-top box 704 through the multi-screen interactive proxy service application 703 deployed on the BRAS 702.

In some practical applications, the above-mentioned association binding may be implemented by an instruction "iptable-t nat-a postcount-d 10.22.91.152-p-tcp-dport 49152-j SNAT-to 100.17.18.19:49152", where an iptable may be created to forward a network packet sent internally from the private network IP10.22.91.152 port 49152 through the public network IP 100.17.18.19 and port 49152, i.e., forward a network packet sent from the IPTV set-top box 704 through port 49152 to the target UE701 through the public network IP.

Step S705, report the platform. The method specifically comprises the following steps: according to the information associated and bound in step S703 and the account related to the IPTV service, the multi-screen interactive proxy service application 703 determines a network connection information set, and reports the network connection information set to the proxy service management platform 705.

For example, the public network IP address "100.17.18.19" of the multi-screen interactive proxy service application 703 may be reported, the IPTV dial-up account number (02044351300@iptv.gd) of the IPTV set-top box 704 may be reported, and the private network IP "10.22.91.152" and the multi-screen interactive port number "49152" of the IPTV set-top box 704 may be reported. Wherein, the IPTV service account (02044351300) can be determined according to the IPTV dialing account (02044351300@iptv.gd).

In some practical applications, after the network connection information group is established, the multi-screen interactive proxy service application 703 may start the proxy service and bind the virtual DMR, and in particular, the multi-screen interactive proxy service application 703 may establish the virtual DMR and bind to the original device service and the information description document.

For example, the DLAN-based multi-screen interactive DMR service information may be used for the target UE701 to discover services and transmit multi-screen interactive control commands. In the process, after the IPTV set-top box 704 is started normally, the DMR (Digital Media Renderer) sends a discovery broadcast of the DLAN to the gateway (i.e., the BRAS 702), and after the gateway receives the information, a virtual DMR can be established; after the target UE701 discovers the virtual DMR, when it sends a multi-screen interactive control command, it considers that the multi-screen interactive proxy service application 703 on the BRAS702 is a terminal to be controlled by it, but in reality, the multi-screen interactive proxy service application 703 forwards all control network packets to the IPTV set-top box 704, and the control network packets are executed by the actual DMR. Therefore, virtual forwarding can be performed between the target UE701 and the IPTV set top box 704 by taking the multi-screen interaction proxy service application 703 as a medium, the defect that the DLNA protocol does not support cross-network is overcome, and the discovery and multi-screen interaction of the cross-network terminal are realized.

In step S707, the target UE701 discovers the multi-screen interactive proxy service application 703 based on UPnP. The method specifically comprises the following steps: the multi-screen interactive APP on the target UE701 initiates a service discovery request to cause the proxy service management platform 705 to return the public IP address and multi-screen interactive port number of the corresponding multi-screen interactive proxy service application 703.

For example, the multi-screen interaction APP on the target UE701 may send an IPTV service account number of the IPTV set-top box 704 to which the multi-screen interaction APP is bound, so that the proxy service management platform 705 may find, according to the IPTV service account number, a public network IP address and a multi-screen interaction port number of the corresponding multi-screen interaction proxy service application 703: 100.17.18.19:49152.

In step S709, the multi-screen interaction APP on the target UE701 sends a multi-screen interaction control command to the BRAS proxy service.

The multi-screen interactive control command may be, for example, a multi-screen interactive play request message, where the message may include a message sending manner (such as POST), a play execution manner (such as executed by a STB set-top box DMR), a message sending address (such as an IP address of a virtual DMR indicated by "HOST:100.17.18.19", that is, an address of the multi-screen interactive proxy service application 703), a message sending Port (such as a Port of the virtual DMR indicated by "Port: 49152"), a service protocol (such as a DLNA based on the UPNP protocol), a media URL that needs to be played by the DMR (such as a Port indicating an IP address of the target UE701 and a media service by "116.179.32.98:77/pikachu.m3u8", and a URI of the media), and so on.

Step S711, IP conversion. The method specifically comprises the following steps: after receiving the multi-screen interaction control command, the proxy service management platform 705 may search the private network IP address and port of the corresponding IPTV set-top box 704 according to the port number therein.

For example, after receiving the multi-screen interactive play request message in step S709, the multi-screen interactive proxy service application 703 may perform IP address conversion on the private network IP address 10.22.91.152:49152 and the public network IP address 100.17.18.19:49152 according to the iptable. In some practical applications, if security is required, the play address in the request message (i.e. "pikachu.m3u8" in step S709) may also be added to the whitelist.

In some practical applications, the multi-screen interactive proxy service application 703 may add the IP of the play address in the request message (i.e. "116.179.32.98" in step S709) to the routing table, so that when the IPTV set-top box 704 accesses the IP of the play address, it may access through the internet outlet.

In step S713, the multi-screen interactive control command is forwarded. The method specifically comprises the following steps: the multi-screen interactive proxy service application 703 forwards the multi-screen interactive control command to the IPTV set-top box 704, and the IPTV set-top box 704 executes after receiving the multi-screen interactive control command, such as playing media, pausing, and the like.

In the case that the multi-screen interaction control command is a play command, the method further includes:

step S715, forwarding the play command. The method specifically comprises the following steps: the multi-screen interactive proxy service application 703 forwards the play command to the IPTV set-top box 704, and the IPTV set-top box 704 sends a media stream acquisition request to the multi-screen interactive proxy service application 703, and the multi-screen interactive proxy service application 703 forwards the media stream acquisition request to the target UE701, so that the target UE701 acquires the corresponding media content (i.e., the media stream).

For example, the play command may include media stream address information:

"116.179.32.98:77/pikachu.m3u8", the IPTV set-top box 704 may generate a media stream acquisition request containing the media stream address information after receiving the play command, and then send the media stream acquisition request to the multi-screen interactive proxy service application 703. The multi-screen interactive proxy service application 703 is further sent to the target UE701 through the internet (i.e. the public network 100.17.18.19) according to the routing table 116.179.32.98, so that the target UE701 responds to the media stream acquisition request to acquire the media content corresponding to "116.179.32.98:77/pikachu.m3u8".

Step S717 media playback. The method specifically comprises the following steps: the multi-screen interaction APP on the target UE701 transmits the acquired media content to the multi-screen interaction proxy service application 703, and the media content is forwarded to the IPTV set top box 704 for decoding and playing through the multi-screen interaction proxy service application 703.

FIG. 8 shows an interaction flow diagram of a method for implementing multi-screen interaction according to one embodiment of the disclosure, including:

step S801, network dialing. In this step, the BRAS may receive a dialing request sent by the target IPTV set-top box based on the IPTV dialing account, so as to implement network dialing of the IPTV set-top box.

In step S803, an IP address is allocated in response to the dial request. In this step, the BRAS may determine, in response to a dial request, a private network IP address and a multi-screen interaction port for allocation to a target IPTV set-top box from an IPTV private network address pool, and send the private network IP address to the target IPTV set-top box; the BRAS may further determine an IPTV service account according to the IPTV dialing account, and obtain a public network IP address of the BRAS for the multi-screen interactive service.

Step S805, binding the IPTV service account, the private network IP address and the port to the public network IP address and the port of the multi-screen interactive service. In this step, the multi-screen interactive proxy service on the BRAS may bind the IPTV service account, the private network IP address, the multi-screen interactive port, and the public network IP address, to generate a network connection information set.

Step S807, reporting the binding relationship to the management platform. In the step, the multi-screen interactive proxy service can report the network connection information group to a proxy service management platform located in the wide area network through a core router CR; the proxy service management platform receives and stores a network connection information group reported by the multi-screen interaction proxy service application; the network connection information group comprises an IPTV service account number, a private network IP address, a multi-screen interaction port and a public network IP address which are used for the same multi-screen interaction service.

Step S809, the mobile phone multi-screen interaction APP initiates UPnP discovery and reports the bound IPTV account. In the step, the target UE can log in a multi-screen interactive application program based on an IPTV service account; the target UE can send a service discovery request carrying an IPTV service account to the proxy service management platform; the proxy service management platform can receive a service discovery request carrying an IPTV service account number sent by the target UE.

Step S811, searching a BRAS of the corresponding multi-screen interactive service according to the IPTV account number, and returning to the corresponding public network IP and port. In the step, the proxy service management platform can search a public network IP address and a multi-screen interaction port corresponding to the IPTV service account from the network connection information group; the proxy service management platform can send the public network IP address and the multi-screen interaction port to the target UE; the target UE may receive a public network IP address and a multi-screen interaction port corresponding to the IPTV service account returned by the proxy service management platform.

Step S813, a multi-screen interaction control command is sent to the IP address and port declared by the proxy service. In this step, the target UE may send a multi-screen interaction control command to a multi-screen interaction proxy service application corresponding to the public network IP address and the multi-screen interaction port; the multi-screen interactive control commands may include a play command, a pause command, a fast forward command, and a fast reverse command.

Step S815, searching the private network IP and the port corresponding to the set top box according to the port. In this step, the multi-screen interactive proxy service application responds to the multi-screen interactive control command, and may perform IP address conversion according to the network connection information set stored in the BRAS and corresponding to the multi-screen interactive service to obtain the private network IP and the multi-screen interactive port for the multi-screen interactive service (i.e., the multi-screen interactive proxy service application may search the private network ip+ port corresponding to the public network ip+ port based on the network connection information set).

Step S817, forwarding the multi-screen interactive control command. In this step, the multi-screen interaction proxy service application may send a multi-screen interaction control command to the target IPTV set-top box corresponding to the private network IP address and the multi-screen interaction port, so that the target IPTV set-top box executes the multi-screen interaction control command.

Fig. 9 shows an interaction flow chart of a playing method in a case where a multi-screen interaction control command is a playing command in a multi-screen interaction implementation method according to an embodiment of the present disclosure, where the interaction flow chart includes:

step S901, a play command is sent to the IP address and port declared by the proxy service. In this step, the target UE may send a play command including a play address of the data stream to the multi-screen interactive proxy service application.

Step S903, searching the private network IP and the port corresponding to the set top box according to the port. In this step, the multi-screen interactive proxy service application may perform IP address conversion according to the network connection information set stored in the BRAS and corresponding to the multi-screen interactive service in response to the play command, to obtain the private network IP and the multi-screen interactive port for the multi-screen interactive service (i.e., the multi-screen interactive proxy service application may search the private network ip+ port corresponding to the public network ip+ port based on the network connection information set).

Step S905, forward the play command. In this step, the multi-screen interactive proxy service application may forward the play command to the target IPTV set-top box corresponding to the private network IP address and the multi-screen interactive port.

In step S907, the STB (set top box) receives the play command, generates a data stream acquisition request based on the play address in the play command, and sends the data stream acquisition request to the proxy service. In this step, the target IPTV set-top box may generate a media stream acquisition request based on the play command, and send the media stream acquisition request to the multi-screen interactive proxy service application.

Step S909, a media stream acquisition request is transmitted. In this step, the multi-screen interactive proxy service application forwards the media stream acquisition request received from the IPTV set-top box to the target UE.

In step S911, a media stream is delivered. In this step, after receiving a media stream acquisition request sent by the multi-screen interactive proxy service application, the target UE may acquire media stream data according to the media stream acquisition request, and transmit the media stream data to the multi-screen interactive proxy service application.

Step S913, according to the port of the issued media stream, the media stream is forwarded to the private network IP and port of the corresponding STB (set top box). In this step, the multi-screen interactive proxy service application may transmit media stream data received from the target UE to the target IPTV set-top box.

Step S915, play the media stream. In this step, the target IPTV set-top box may decode and play the media stream data.
