Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 5, fig. 5 is a schematic flowchart of a multicast program receiving method according to an embodiment of the present invention. The multicast program receiving method can be applied to a set top box, and after the set top box is connected with a port of a router, the set top box and a broadband access server establish a tunnel, so that the multicast group where the broadband access server is located is added and the multicast program is received through the tunnel, the problem that the set top box cannot receive the multicast program when an ITV interface is not accessed is solved, and the convenience of receiving the multicast program is improved. The multicast program receiving method includes step S101 and step S102.

Step S101, after the port of the router is connected, a tunnel is established with the broadband access server.

It should be noted that, in the embodiment of the present invention, when the set-top box is not connected to the designated ITV interface or does not purchase a device of the ITV interface, a tunnel may be established between the set-top box and the broadband access server after the set-top box is connected to the port of the router; therefore, the multicast group where the broadband access server is located can be added through the tunnel, and the multicast program issued by the broadband access server is acquired.

The ITV interface is an interface connected with a set-top box used by the IPTV service, and is used for receiving multicast television programs in a mode that the set-top box joins in and leaves a multicast group through the ITV interface. The ports of the router may include LAN (Local Area Network) interfaces.

It is understood that a multicast group is identified using an IP multicast address; any user host (or other receiving device) joins a multicast group, and becomes a member of the multicast group, and can identify and receive the IP message with the IP multicast address as the destination address. The membership in the multicast group is dynamic and the subscriber hosts in the network can join and leave the multicast group at any time. In the embodiment of the invention, the set top box establishes the tunnel with the broadband access server and can join the multicast group corresponding to the broadband access server through the tunnel, so that the multicast program can be acquired through the broadband access server.

It should be noted that, in the embodiment of the present invention, the tunnel refers to an L2TP tunnel established based on an L2TP Protocol (Layer 2 Tunneling Protocol); the L2TP protocol is one of VPDN (Virtual private dial-up Network) tunneling protocols.

In some embodiments, before establishing the tunnel with the broadband access server, the method may include: establishing communication connection with management equipment through a router; and acquiring the tunnel dialing parameters issued by the management equipment.

Illustratively, the communication connection may be established with the management device according to the IP address allocated by the router based on a PPP (Point-to-Point Protocol) or a SLIP Protocol (Serial Line Internet Protocol). Therefore, the management equipment can detect the network state of the set top box and acquire the equipment parameters of the set top box; the set-top box can receive the tunnel dialing parameters issued by the management equipment.

Illustratively, the tunnel dialing parameters may include, but are not limited to, a dialing token, a broadband access IP address, a dialing account number, a password, and control routing information, among others. The dialing mark is used for determining whether the broadband access server needs to be dialed or not so as to establish a tunnel; the broadband access IP address refers to an IP address corresponding to the broadband access server serving as an LNS end; the dialing account and the password are used for establishing point-to-point communication connection with the broadband access server; and the control routing information is used for carrying out service authentication on the set top box in the service authentication platform.

The communication connection is established between the router and the management equipment, the tunnel dialing parameters issued by the management equipment can be acquired, and a tunnel can be established with the broadband access server according to the tunnel dialing parameters.

In some embodiments, after the tunnel dialing parameter issued by the management device is obtained, a tunnel may be established with the broadband access server according to the tunnel dialing parameter. A tunnel is established between the set top box and the broadband access server, so that data messages between the set top box and the broadband access server are transmitted in the tunnel; the set-top box can be added to or separated from the multicast group corresponding to the broadband access server through the data packet, and further, the multicast program forwarded by the broadband access server can be acquired.

In some embodiments, establishing a tunnel with the broadband access server according to the tunnel dialing parameter may include: when the mark value corresponding to the dialing mark is a preset mark value, establishing point-to-point communication connection with a broadband access server based on a point-to-point protocol according to the dialing account number and the password; based on the point-to-point communication connection, dialing is carried out on the broadband access server according to the broadband access IP address so as to establish a tunnel between the set top box and the broadband access server.

Illustratively, the dialing Flag may be denoted by Flag. In the embodiment of the present invention, the preset Flag value is Flag 1. The Flag value corresponding to the dial Flag may include Flag 1 and Flag 0. When the Flag value is 1, the dialing is indicated; when the Flag value is 0, it indicates that no dialing is performed.

By judging the dialing marks, whether dialing is needed or not can be determined according to the mark values corresponding to the dialing marks.

Illustratively, when the Flag value corresponding to the dialing Flag is a preset Flag value Flag equal to 1, it is determined that the broadband access server needs to be dialed to establish the tunnel.

It will be appreciated that the dialing procedure is the tunnel establishment procedure. Before establishing a tunnel with the broadband access server, a point-to-point communication connection needs to be established with the broadband access server, so that a message can be sent to the broadband access server through the point-to-point communication connection.

Illustratively, the point-to-point communication connection is established with the broadband access server based on the dialing account number and the password based on a point-to-point protocol.

The PPP Protocol is a point-to-point serial communication Protocol, and includes a link Control Protocol lcp (link Control Protocol), a network Control Protocol ncp (network Control Protocol), a password Authentication Protocol pap (password Authentication Protocol), and a Challenge Handshake Authentication Protocol (Challenge-Handshake Authentication Protocol). The PPP protocol has functions of handling error detection, supporting multiple protocols, allowing negotiation of IP addresses at the time of connection, allowing authentication, and the like.

Illustratively, based on the PPP protocol, a PPP data frame is generated according to the dialing account and the password, and the PPP data frame is sent to the broadband access server through the router. After receiving the PPP data frame, the broadband access server authenticates the set-top box according to the dialing account and the password in the PPP data frame; and when the authentication is completed, allowing the point-to-point communication connection to be established with the set top box.

By establishing a point-to-point communication connection with the broadband access server based on a point-to-point protocol, the broadband access server may be dialed after the point-to-point communication connection is established to establish a tunnel between the set-top box and the broadband access server.

In some embodiments, after establishing the point-to-point communication connection with the broadband access server, the broadband access server may be dialed based on the broadband access IP address based on the point-to-point communication connection. As shown in fig. 6, fig. 6 is a schematic flowchart of substeps of dialing a broadband access server according to an embodiment of the present invention, which may specifically include the following steps S1011 to S1013.

Step S1011, determining the target IP address of the broadband access server according to the broadband access IP address.

Step S1012, sending a tunnel establishment request message to the broadband access server according to the target IP address, so that the broadband access server returns a response message according to the tunnel establishment request message.

Step S1013, receiving the response message returned by the broadband access server, and sending a confirmation message to the broadband access server according to the response message.

It should be noted that, in the process of establishing the tunnel, the set-top box serves as an LAC (L2TP Access Concentrator ) end, and the broadband Access Server serves as an LNS (L2TP Network Server ) end. Wherein, the LAC end is used as a side end point of the L2TP tunnel; the LNS end is used as the end point of the other side of the L2TP tunnel, and is the opposite end device of the LAC end.

Illustratively, the broadband access IP address in the tunnel dialing parameter may be used as the target IP address corresponding to the LNS. So that the destination of the transmitted message can be determined according to the target IP address.

Referring to fig. 7, fig. 7 is a schematic diagram of tunnel establishment and session establishment according to an embodiment of the present invention. The L2TP tunnel establishment procedure may include, but is not limited to, a tunnel establishment request message, a response message, and an acknowledgement message.

It should be noted that the tunnel establishment request message may be represented as an sccrq (start Control Connection request) message, and is used for the set-top box to request the broadband access server to establish the Control Connection. The response message may be represented as an sccrp (start Control Connection reply) message, which is used by the broadband access server to notify the set-top box that the broadband access server receives the SCCRQ message of the set-top box and allows the establishment of the Control Connection. SCCCN may be denoted as SCCCN (start Control Connection connected) message, which is used for the set-top box to tell the broadband access server, and the set-top box receives the SCCRP message from the broadband access server, thereby implementing establishment of the tunnel.

The tunnel establishment with the broadband access server can be realized by sending a tunnel establishment request message to the broadband access server; therefore, the multicast group where the broadband access server is located can be added and the multicast program can be received based on the tunnel, the problem that the set top box cannot receive the multicast program when the set top box is not accessed to the ITV interface is solved, and the convenience of receiving the multicast program is improved.

And step S102, based on the tunnel, adding the multicast group corresponding to the broadband access server to acquire the multicast program issued by the broadband access server.

Referring to fig. 8, fig. 8 is a schematic flowchart illustrating a sub-step of joining the multicast group corresponding to the broadband access server based on the tunnel in step S102 to obtain the multicast program delivered by the broadband access server, and specifically may include the following steps S1021 to S1023.

And S1021, establishing a point-to-point session with the broadband access server based on the tunnel.

It should be noted that each tunnel may carry multiple point-to-point sessions. In the embodiment of the invention, after the tunnel is established with the broadband access server, the point-to-point session needs to be established with the broadband access server; therefore, the user data message and/or the multicast data message transmitted in the tunnel are/is realized.

Referring to fig. 7, the process of session establishment is similar to the process of tunnel establishment, and an icrq (incoming Call request) message is initiated to the broadband access server by the set-top box; the broadband access server returns an ICRP (incoming Call reply) message after receiving the ICRQ message; the set-top box returns an ICCN (Integrated Call connected) message after receiving the ICRP message, thereby realizing the establishment of the session in the tunnel.

Wherein, the ICRQ message represents a session establishment request message; an ICRP (incorporating Call reply) message represents a session establishment response message; the iccn (incoming Call connected) message represents a session establishment confirmation message.

For example, as shown in fig. 7, after a tunnel is established with the broadband access server, the tunnel needs to be maintained. For example, a HELLO message may be sent to the broadband access server at regular time, or a zlb (zero Length body) returned by the broadband access server is received for confirmation. Wherein, the ZLB message is a message header with only L2TP bytes.

The control routing information can be sent to the broadband access server for service authentication by establishing a point-to-point session with the broadband access server based on the tunnel.

Step S1022, after the point-to-point session is successfully established, sending the control routing information to the broadband access server, so that the broadband access server performs service authentication on a service authentication platform according to the control routing information, and after the service authentication is completed, adding the set top box to the multicast group.

Illustratively, the control routing information may include an IP address corresponding to the set-top box.

Illustratively, the control routing information may be sent to a broadband access server; the broadband access server can send the control routing information to the service authentication platform for service authentication. After passing service authentication, the broadband access server may mark the IP address in the control routing information as an IP multicast address. Therefore, the set-top box can join the multicast group in which the broadband access server is positioned through the IP multicast address.

It can be understood that only the device with the address of the IP multicast address can join the multicast group where the broadband access server is located; therefore, the multicast data message sent by the broadband access server can be received, and the multicast program can be received.

It should be noted that, in the embodiment of the present invention, the service authentication platform performs service authentication on the control routing information, so that the IP address of the set-top box is marked with an IP multicast address, and thus the set-top box can join the multicast group in which the broadband access server is located. The multicast program of the service authentication platform can be pushed to the set-top box through the broadband access server in a multicast mode; the set-top box can receive the multicast by dynamically joining and leaving the multicast group, and the problems of video watching blockage and the like caused by occupation of server resources and network bandwidth by a large amount of network connection are solved.

Step S1023, receiving the multicast program sent by the broadband access server, wherein the multicast program is sent to the broadband access server by the service authentication platform after the service authentication is completed.

Illustratively, after the broadband access server completes service authentication on the service authentication platform according to the control routing information, the IP address corresponding to the set-top box becomes an IP multicast address, and the set-top box may receive a multicast program sent by the broadband access server through a multicast data packet.

It should be noted that, after receiving the multicast program issued by the service authentication platform, the broadband access server may forward the multicast program to all multicast users in the multicast group.

For example, if the broadband access server receives the multicast program a delivered by the service authentication platform, the multicast program a may be forwarded to all multicast users in the multicast group. The set-top box can receive the multicast program A sent by the broadband access server based on the tunnel.

In this embodiment of the present invention, after joining the multicast group corresponding to the broadband access server based on the tunnel, the method may further include: transmitting a multicast data message with the broadband access server based on the tunnel to acquire the multicast program; or based on the tunnel, transmitting the user data message with the broadband access server to acquire the unicast program issued by the broadband access server.

The user data message is used for data transmission between the set top box and the broadband access server when the set top box plays the unicast program; the multicast data message is used for data transmission between the set-top box and the broadband access server when the set-top box plays the multicast program. The following describes the transmission of user data packets and multicast data packets in a tunnel, respectively.

Referring to fig. 9, fig. 9 is a schematic flowchart of a sub-step of transmitting a user data packet with a broadband access server according to an embodiment of the present invention, which may specifically include the following steps S1031 to S1034.

Referring to fig. 10, fig. 10 is a schematic diagram illustrating user data packet transmission in a tunnel according to an embodiment of the present invention.

And step S1031, generating a user data message.

Illustratively, the user data message is generated by the user data to be sent. For example, the user datagram may be represented as IP1 bytes.

Step S1032, the user data message is packaged, and the packaged user data message is obtained.

Illustratively, the User data packet is encapsulated based on a PPP Protocol, an L2TP Protocol, and a UDP Protocol (User Datagram Protocol), respectively, where the encapsulated User data packet carries PPP bytes, L2TP bytes, and UDP bytes.

Step S1033, based on the tunnel, sending the encapsulated user data packet to the broadband access server, so that the broadband access server decapsulates the encapsulated user data packet, processes the decapsulated user data packet to obtain a response data packet, and encapsulates the response data packet.

For example, before sending the encapsulated user data packet to the broadband access server, the encapsulated user data packet may be encapsulated by a router into an IP packet transmitted over the Internet, where the IP packet also carries an IP2 address and an MAC address, and may be transmitted over a tunnel by a public network IP2 address. The MAC byte is used to indicate a Media Access Control (MAC) address.

Illustratively, after receiving the IP packet, the broadband access server decapsulates the IP packet. For example, the L2TP byte and PPP byte in the IP message are stripped to obtain the user data message after decapsulation. The broadband access server can process the unpacked user data message to generate a response data message; and then sending the response data message to the set-top box through the tunnel. Before sending, the response data message needs to be packaged; for example, the response data packet is encapsulated based on the PPP protocol, the L2TP protocol, and the UDP protocol, and the encapsulated response data packet carries the PPP byte, the L2TP byte, and the UDP byte. The broadband access server sends the packaged response data message to the set-top box through the tunnel.

Step S1034, receiving the response data packet after encapsulation returned by the broadband access server, and decapsulating the response data packet after encapsulation to complete transmission of the user data packet.

Illustratively, the set top box may receive, through the tunnel, the encapsulated response data packet returned by the broadband access server, and strip the PPP byte, the L2TP byte, and the UDP byte carried in the encapsulated response data packet to obtain the response data packet.

The user data message is generated, packaged and sent to the broadband access server through the tunnel, and the response data message returned by the broadband access server is received, so that the user data message is transmitted through the tunnel and the broadband access server.

Referring to fig. 11, fig. 11 is a schematic flowchart of a sub-step of transmitting a multicast data packet with a broadband access server according to an embodiment of the present invention, which may specifically include the following steps S1041 to S1044.

Referring to fig. 12, fig. 12 is a schematic diagram of transmitting a multicast data packet in a tunnel according to an embodiment of the present invention.

Step S1041, generating a multicast data packet, and adding a multicast header byte to the multicast data packet to obtain a multicast data packet carrying a multicast header.

Illustratively, the multicast data message is generated by the multicast data to be sent. For example, the multicast data packet may be represented as IP1 bytes.

After the multicast data packet is generated, multicast header bytes may be added to the multicast data packet based on the IGMP protocol. Wherein, the multicast header byte can be represented by IGMP.

It should be noted that, when transmitting multicast data, all receiver hosts participating in multicast transmission must apply IGMP protocol. The IGMP (Internet Group Management Protocol) is a Protocol in the TCP/IP Protocol family responsible for IPv4 multicast member Management, and is used to establish and maintain a multicast Group member relationship between an IP host and a multicast router directly adjacent to the IP host.

Step S1042, performing encapsulation processing on the multicast data packet carrying the multicast header to obtain an encapsulated multicast data packet.

Illustratively, the multicast data packet carrying the multicast header is encapsulated based on a PPP Protocol, an L2TP Protocol, and a UDP Protocol (User Datagram Protocol), respectively, where the encapsulated multicast data packet carries IGMP bytes, PPP bytes, L2TP bytes, and UDP bytes.

For example, before sending the encapsulated multicast data packet to the broadband access server, the encapsulated user data packet may be encapsulated by the router into an IP packet transmitted over the Internet, where the IP packet also carries an IP2 address and an MAC address, and may be transmitted over a tunnel by a public network IP2 address.

Step S1043, based on the tunnel, sending the encapsulated multicast data packet to the broadband access server, so that the broadband access server decapsulates the encapsulated multicast data packet, processes the decapsulated multicast data packet to obtain a response data packet, and encapsulates the response data packet.

For example, before sending the encapsulated multicast data packet to the broadband access server, the encapsulated multicast data packet may be encapsulated by the router into an IP packet transmitted over the Internet, where the IP packet may be transmitted over a tunnel by using the public network IP2 address.

Illustratively, after receiving the IP packet, the broadband access server decapsulates the IP packet. For example, the IGMP byte, L2TP byte, and PPP byte in the IP packet are stripped to obtain the multicast data packet after decapsulation. The broadband access server can process the decapsulated multicast data message to generate a response data message; and then sending the response data message to the set-top box through the tunnel. Before sending, the response data message needs to be packaged; for example, the response data packet is encapsulated based on the IGMP protocol, the PPP protocol, the L2TP protocol, and the UDP protocol, and the encapsulated response data packet carries the IGMP byte, the PPP byte, the L2TP byte, and the UDP byte. The broadband access server sends the packaged response data message to the set-top box through the tunnel.

Step S1044 is to receive the response data packet after encapsulation returned by the broadband access server, and perform decapsulation processing on the response data packet after encapsulation to complete transmission of the multicast data packet.

Illustratively, the set top box may receive, through the tunnel, the encapsulated response data packet returned by the broadband access server, and strip the IGMP byte, the PPP byte, the L2TP byte, and the UDP byte carried in the encapsulated response data packet to obtain the response data packet.

The multicast data message is generated, packaged and then sent to the broadband access server through the tunnel, the response data message returned by the broadband access server is received, and the transmission of the multicast data message is carried out through the tunnel and the broadband access server, so that a user can normally receive the multicast program and watch the multicast program under the condition that the set top box is not connected with the ITV interface.

The multicast program receiving method, the set top box, the management device, the system and the storage medium provided by the embodiment establish communication connection with the management device through the router, and can acquire the tunnel dialing parameter issued by the management device, so that a tunnel can be established with the broadband access server according to the tunnel dialing parameter; by judging the dialing marks, whether dialing is needed or not can be determined according to the mark values corresponding to the dialing marks; the method comprises the steps that a point-to-point communication connection is established with a broadband access server based on a point-to-point protocol, and the broadband access server can be dialed after the point-to-point communication connection is established so as to establish a tunnel between a set top box and the broadband access server; the method has the advantages that the tunnel establishment can be realized by sending the tunnel establishment request message to the broadband access server, so that the multicast group where the broadband access server is located can be added and multicast programs can be received based on the tunnel, the problem that the set top box cannot receive the multicast programs when the set top box is not accessed to the ITV interface is solved, and the convenience of receiving the multicast programs is improved; the IP address of the set-top box is marked with an IP multicast address by performing service authentication on the control routing information on a service authentication platform, so that the set-top box can join a multicast group in which a broadband access server is positioned; the IP address of the set-top box is marked with the IP multicast address by performing service authentication on the control routing information on the service authentication platform, so that the set-top box can join the multicast group where the broadband access server is located. The multicast program of the service authentication platform can be pushed to the set-top box through the broadband access server in a multicast mode; the set-top box can receive multicast programs in a mode of dynamically joining and leaving the multicast group, and the problems of video watching stagnation and the like caused by occupation of server resources and network bandwidth by a large amount of network connection are solved; the multicast data message is generated, packaged and then sent to the broadband access server through the tunnel, the response data message returned by the broadband access server is received, and the transmission of the multicast data message is carried out through the tunnel and the broadband access server, so that a user can normally receive the multicast program and watch the multicast program under the condition that the set top box is not connected with the ITV interface.

Referring to fig. 13, fig. 13 is a schematic flowchart of another multicast program management method according to an embodiment of the present invention. The multicast program receiving method can be applied to management equipment, and the tunnel dialing parameters are sent to the set top box after the set top box is connected with the port of the router, so that the set top box establishes a tunnel with the broadband access server according to the tunnel dialing parameters, the multicast group where the broadband access server is located is added and multicast programs are received through the tunnel, the problem that the set top box cannot receive the multicast programs when an ITV interface is not accessed is solved, and the convenience of receiving the multicast programs is improved.

As shown in fig. 13, the multicast program management method includes steps S201 to S203.

Step S201, obtaining the device parameters corresponding to the set top box.

For example, the device parameter corresponding to the set-top box may include account information of the set-top box.

In some embodiments, obtaining the device parameter corresponding to the set top box may include: when the set top box is detected to be started, acquiring the network state of the set top box to determine whether the set top box is connected with a network; and when the set top box is determined to be connected with the network, acquiring the equipment parameters corresponding to the set top box.

By acquiring the network state of the set-top box, whether the set-top box is connected with the network can be determined according to the network state.

It should be noted that, in the embodiment of the present invention, the management device may include a service management client and a service management server.

Illustratively, since the service management client is connected with the set-top box through the router, whether the set-top box is powered on or not can be detected through the service management client. After detecting whether the set top box is started or not, the network state of the set top box can be acquired; and when the set top box is determined to be connected with the network, acquiring the equipment parameters in the set top box.

Illustratively, if the service management client does not detect that the set-top box is connected to the network, the service management client continues to wait until the set-top box is successfully connected to the network.

And S202, authenticating the set top box according to the equipment parameters to obtain an authentication result.

Illustratively, the service management client sends the acquired device parameters to the service management server. The service management server side can authenticate the set top box according to the equipment parameters and send tunnel dialing parameters to the set top box according to the authentication result, so that the set top box establishes a tunnel with the broadband access server according to the tunnel dialing parameters.

In some embodiments, authenticating the set-top box according to the device parameter may include: and when the account information exists in the equipment parameters, authenticating the set top box according to the account information.

For example, the service management server may send the account information to the AAA server, so that the AAA server performs authentication according to the account information and returns an authentication result to the service management server. And the authentication result comprises an IP address corresponding to the set top box.

It should be noted that, an AAA (Authentication, Authorization, Accounting, Authentication, Authorization, and Accounting) server is a server program capable of processing a user access request, providing Authentication Authorization and account services, and mainly aims to manage a user accessing a network server and provide services for the user with access rights.

In other embodiments, authenticating the set-top box according to the device parameter may include: and when the account information does not exist in the equipment parameters, acquiring initial account information corresponding to the set top box, and authenticating the set top box according to the initial account information.

It should be noted that when the set-top box is used for the first time, the account information does not exist in the device parameters of the set-top box, and therefore the initial account information in the set-top box needs to be acquired. It can be understood that each set top box corresponds to one factory account information.

For example, after the AAA server completes authentication, a legal IP address may be allocated as the authentication result.

The set top box is authenticated according to the equipment parameters, so that an authentication result can be obtained; therefore, whether to send the tunnel dialing parameters to the set top box or not can be judged according to the authentication result.

Step S203, sending tunnel dialing parameters to the set-top box according to the authentication result, so that the set-top box establishes a tunnel with a broadband access server according to the tunnel dialing parameters, and acquiring multicast programs issued by the broadband access server based on the tunnel.

For example, the service management server may determine whether to send the tunnel dialing parameter to the set top box according to the authentication result.

In some embodiments, sending the tunnel dialing parameter to the set top box according to the authentication result may include: and when the IP address is a non-IP multicast address, generating tunnel dialing parameters and sending the tunnel dialing parameters to the set-top box.

Illustratively, when the IP address corresponding to the set-top box is determined to be a non-IP multicast address, the service management server generates a tunnel dialing parameter and sends the tunnel dialing parameter to the set-top box; and the set-top box establishes a tunnel with the broadband access server according to the tunnel dialing parameters and joins the multicast group corresponding to the broadband access server. After joining the multicast group corresponding to the broadband access server, the set-top box may obtain, based on the tunnel, a multicast program delivered by the broadband access server.

Illustratively, the tunnel dialing parameters may include, but are not limited to, a dialing token, a broadband access IP address, a dialing account number, a password, and control routing information, among others.

When the IP address corresponding to the set-top box is a non-IP multicast address, the tunnel dialing parameter is sent to the set-top box, so that the set-top box establishes a tunnel with the broadband access server according to the tunnel dialing parameter, the multicast group where the broadband access server is located is added and multicast programs are received through the tunnel, the problem that the set-top box cannot receive the multicast programs when the set-top box is not accessed to an ITV interface is solved, and the convenience of receiving the multicast programs is improved.

In other embodiments, when the IP address is an IP multicast address, the IP address is sent to the broadband access server, so that the broadband access server performs service authentication on the service authentication platform according to the IP address.

For example, the broadband access server may send the IP address corresponding to the set top box to the service authentication platform for service authentication. After passing service authentication, the broadband access server can determine that the IP address corresponding to the set-top box is an IP multicast address. The set-top box can join the multicast group where the broadband access server is located through the IP address.

The embodiments described above provide a multicast program management method, a set-top box, a management device, a system, and a storage medium, and by obtaining a network state of the set-top box, whether the set-top box is connected to a network can be determined according to the network state; the set top box is authenticated according to the equipment parameters, so that an authentication result can be obtained, and whether the tunnel dialing parameters are sent to the set top box or not can be judged according to the authentication result; when the IP address corresponding to the set-top box is a non-IP multicast address, the tunnel dialing parameter is sent to the set-top box, so that the set-top box establishes a tunnel with the broadband access server according to the tunnel dialing parameter, the multicast group where the broadband access server is located is added and multicast programs are received through the tunnel, the problem that the set-top box cannot receive the multicast programs when the set-top box is not accessed to an ITV interface is solved, and the convenience of receiving the multicast programs is improved.
