Description

The present invention relates to the field of communications, and in particular to a broadcast control method and apparatus in Internet Protocol Television (IPTV). Background technique

IPTV refers to the provision of on-demand or multicast video services to users on a network based on Internet Protocol (IP). IPTV is gaining increasing attention as a new technology that provides home users with a variety of interactive services, including TV content. It uses telecom broadband network as the transmission channel and TV as the terminal. It integrates various technologies such as Internet, multimedia and communication, and can effectively integrate the three fields of TV, communication and personal computer (Personal Computer, PC for short). Together, it changes the limits of time to people. At the same time, IPTV, as a new high-bandwidth, high-quality Internet multimedia service, puts higher demands on telecom operators' IP metropolitan area networks. Compared with the traditional unicast technology, the multicast technology has the advantage that the network bandwidth does not increase linearly with the number of users on the basis of the same transmission efficiency, which can effectively save the load of the video server and the bearer network. Therefore, it is recommended that telecom operators deploy and implement IPTV services efficiently and economically. End-to-end multicast push is recommended. IPTV is the most typical representative of the current multicast push service. The IPTV service implemented by the current network is often a variety of programs from CCTV, provincial stations and local stations. There are many channels to meet the audience's viewing needs. When a multicast push program is used, each channel has a corresponding multicast route in the middle of the data communication device. The multicast protocol runs on the network and can receive the user's viewing requirements and convert it into a multicast routing request form. After receiving the program stream, it is pushed to the user through the corresponding route. Such functional implementations can be performed using static configuration or dynamic multicast protocols. Due to the flexibility and reusability of the IP network, and the ability to carry multiple composite services, the program stream in the IP network may encounter some illegal insertions or steal the normal program stream address to send illegal programs. Even when an illegal server is built to push illegal programs, the means of monitoring is especially necessary. In the related art, a dedicated broadcast control platform (ie, a device with monitoring function) is often deployed on the backbone network of the province and the city, and the broadcast control platform can monitor the channel program and monitor whether an illegal insertion occurs. In the existing network deployment, although the broadcast control platform can see whether there is illegal insertion, but once the illegal insertion occurs, there is no flexible means to deal with it. If the setting is made through a data communication device such as a router, the channel is set to be illegal, so that the router does not forward its data stream, so that the user does not watch it. However, the above methods have obvious disadvantages: In the related art, the broadcast control platform is located downstream of the router device, so that after the router no longer forwards the channel data stream, the broadcast control platform itself can no longer receive the data stream of the channel. Therefore, the channel cannot be monitored again; and since the broadcast control platform does not see the data stream, it is impossible to judge in time when the channel returns to normal, resulting in a long recovery time of the channel. In addition, the broadcast control platform may have many levels, for example, provincial, municipal, regional, etc. If the downstream does not forward traffic, the monitoring method is undoubtedly too simple, and the monitoring agencies cannot implement their own processing. It is impossible to achieve the purpose of their respective jurisdictions. SUMMARY OF THE INVENTION A primary object of the present invention is to provide a broadcast control scheme in an IPTV to solve at least the problem in the related art that the monitoring device cannot continue to monitor a program after notifying the data communication device to stop forwarding the program. In order to achieve the above object, according to an aspect of the present invention, a broadcast control method in an Internet Protocol Television IPTV is provided, the method comprising: a device having a monitoring function configuring a data communication device on a data communication device to have a monitoring function The interface of the device is a monitoring interface; when the device with the monitoring function monitors that the program is illegal, the device with the monitoring function instructs the data communication device to forward the program on the monitoring interface.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. Embodiment 1 The embodiment of the present invention provides a broadcast control method in an IPTV, which is applied to a monitoring transmission process of an IPTV. FIG. 1 is a flowchart of a broadcast control method in an IPTV according to an embodiment of the present invention. As shown in FIG. 1, the method includes steps S102 to S104. In step S102, the device having the monitoring function configures the interface of the data communication device to the device with the monitoring function on the data communication device as a monitoring interface; wherein the data communication device can be a device for transmitting IPTV data, such as a router or a layer 3 switch. Step S104: When the device with the monitoring function monitors that the program is illegal, the device with the monitoring function instructs the data communication device to forward the program on the monitoring interface. In this embodiment, the interface between the data communication device and the device having the monitoring function is set as the monitoring interface, and when the program is detected to be illegal, the program is still forwarded on the monitoring interface, but is not forwarded on the interface to the user equipment. The program, so that downstream users who need to be shielded can no longer receive the program stream of the channel, and the device with monitoring function is not affected. The device with the monitoring function described above may be a broadcast control platform. Step S102 can be implemented in the following manner: In the first mode, the device with the monitoring function pre-sets the data communication device to the interface of the device with the monitoring function as the monitoring interface. In the second mode, the device with the monitoring function sends a configuration command to the data communication device through the network management page, and instructs the data communication device to record the interface of the data communication device to the device with the monitoring function as a monitoring interface. In order to resume the forwarding of the program that is illegally converted to normal in time, after the step S104, if the device having the monitoring function monitors that the illegal program is restored to normal, the data communication device is instructed to resume using the interface to the user device to forward the program. Preferably, the user equipment is a user equipment within the jurisdiction of the device with the monitoring function. That is to say, when there are multiple monitoring function devices, each device only controls whether the data communication device forwards the program to the user equipment under the jurisdiction of the monitoring function device, and the user equipment under the jurisdiction of other devices does not limit. . Preferably, the program illegally includes at least one of the following: the channel transmitting the program is illegal; the program contains illegal content. If a new channel program is illegally generated on the network using an individual device, it may be determined that the channel for transmitting the program is illegal; if an illegal program is transmitted on the existing channel, it may be determined that the content contained in the program is illegal. In both cases, it needs to be monitored. In this embodiment, the broadcast control platform can not only process a single channel, but also set the downstream user or the hierarchical monitoring according to the needs of the user, so that the downstream user who needs to be shielded can no longer receive the program stream of the channel. Other broadcast control platforms and other jurisdictions are not affected. Moreover, after the program returns to normal, the downstream user can quickly receive the channel program stream again. Therefore, this embodiment can make the channel control more specific and flexible. Embodiment 2 This embodiment provides the following implementation mechanism when a multicast application is deployed on a data communication device such as a router or a Layer 3 switch: The user can configure some outgoing interfaces as monitoring interfaces, and an illegal channel is detected. For content, you can configure the route blocking command so that the interface to the user of the channel no longer forwards the program stream, but the previously configured monitoring interface is not affected. The process of configuring the monitoring interface can also be implemented by using a command from the network management system to the data communication device. Moreover, when there are multiple broadcast control platforms, it is possible to control only the user interfaces of the respective jurisdictions, so that the jurisdiction users of other broadcast control platforms are not affected. At the same time, the broadcast control platform can also monitor all illegal push programs for monitoring and blocking processing. In this embodiment, the process of performing the broadcast control in the IPTV includes the following steps: Step 1: The broadcast control platform configures the monitoring interface on the data communication device (for example, a router or a Layer 3 switch) in advance. The broadcast control platform can also transfer configuration commands to the data communication device through the network management page. The specific method for configuring the monitoring interface includes: The broadcast control platform collects the interface connected to the broadcast control platform according to the network plan, and configures the monitoring interface to the data communication device by using the command. Similarly, the monitoring interface command can be issued through the network management page. After receiving the command, the data communication device does not operate on the current multicast route, but only records. Step 2: The broadcast control platform finds that the program stream of a certain channel has illegal content, and then releases the channel blocking command to the data communication device, and the multicast communication channel corresponding to the channel only retains the previously configured monitoring interface on the data communication device, and other The outgoing interfaces are all deleted (that is, other interfaces to the user equipment no longer forward the program stream). Specifically, the broadcast control platform finds that the program stream of a certain channel has illegal content, and the channel blocking command is sent to the data communication device. The order of the command may be directly configured through the data communication device, or may be performed through the network management system. Issued. The data communication device receives the blocking command, and deletes the outgoing interface except the monitoring interface for the multicast route corresponding to the channel specified in the command. In this way, in addition to the broadcast control platform, other downstream users will no longer receive illegal program content. Step 3: After the broadcast control platform finds that the channel program returns to normal, the command to release the channel block is sent to the data communication device, and then the multicast route corresponding to the channel is restored to the normal outgoing interface on the data communication device. The specific steps of the above recovery process are as follows: If the broadcast control platform finds that the channel program is restored to normal, the command to release the channel block is released to the data communication device, and the command release process may be performed by directly configuring the command on the data communication device, or Delivered through the network management. The data communication device receives the command to release the channel block, and restores the normal original outgoing interface to the multicast route corresponding to the channel specified in the command. In this way, his downstream users other than the broadcast control platform resume normal reception of the channel program. It should be noted that when multiple broadcast control platforms exist, the user can implement independent control, that is, a broadcast control platform only controls the user outbound interface within its jurisdiction, and blocks when receiving illegal programs. For user outbound interfaces that are not under the jurisdiction, they are not blocked. Specifically, when there are multiple broadcast control platforms, the scope and user of each broadcast control platform are different. When a broadcast control platform finds that a program stream is illegal, a blocking command is issued, and the user under the control of the broadcast control platform no longer receives the program stream, and the users under the control of other broadcast control platforms are not affected. In a specific example, the user can monitor the channels being transmitted on all data communication devices, and if private programs are spread on the Internet, monitor their programs and block control. Specifically, in the network, there may be an individual device used to propagate illegal programs. At this time, on the data communication device, all the program streams being transmitted may be sent to the broadcast control platform, and the broadcast control platform finds such illegal programs. Afterwards, an instruction to block the channel stream transmission of the channel can be issued to the data communication device, so that the data communication device stops transmitting the illegal program to the user. In this embodiment, a special control method is adopted for the multicast route corresponding to the channel on the data communication device, so that the receiving line of the program stream can be controlled according to the needs of the broadcast control without affecting the network planning, and at the same time, It affects the monitoring of the broadcast control platform, and can control differently according to the control range of the broadcast control platform, and also monitors and processes the propagation of illegal channels. Therefore, the embodiment improves the flexibility and convenience of program broadcast control. Embodiment 3 Figure 2 is a schematic diagram of networking of a single broadcast control platform according to an embodiment of the present invention. This embodiment is implemented in the networking shown in Figure 2. The router receives several program streams and connects to the broadcast control platform and two user groups. The interface 1 of the router is connected to the broadcast control platform, and the interface 2 and the interface 3 are respectively connected to the user group. The broadcast control platform can monitor all program streams. 3 is a flowchart of a data control method according to an embodiment of the present invention. The broadcast control method in this embodiment includes: configuring interface information of a broadcast control platform to a data communication device, where the data communication device is a router, specifically The interface 1 is configured as a monitoring interface, and the data communication device records this information, but does not perform other operations (step S302 of FIG. 3). The broadcast control platform monitors the program stream. If the broadcast control platform finds that program 1 is illegally inserted and illegal content occurs, the channel blocking command is sent to the data communication device, and the data communication device only reserves the multicast route corresponding to the program 1 to the broadcast control platform. The interface 1 is an outgoing interface, and the interface 2 and the interface 3 connected to the user group are deleted from the corresponding multicast routing outbound interface of the program 1. Thus, except for the broadcast control platform, the other program groups cannot receive the program stream (step S304 of Fig. 3). Embodiment 4 FIG. 4 is a schematic diagram of networking of multiple broadcast control platforms according to an embodiment of the present invention. This embodiment is implemented in the networking shown in FIG. 4. The router receives several program streams and connects two broadcast control platforms and two user groups.

Among them, the user group 1 is only controlled by the broadcast control platform 1, and the user group 2 is only controlled by the broadcast control platform 2. Both the broadcast control platform 1 and the broadcast control platform 2 can monitor all program streams. The broadcast control method in this embodiment includes: configuring interface information of the broadcast control platform to the data communication device, wherein the data communication device is a router, and the interface 1 and the interface 2 are the broadcast control platform interface (SP, monitoring interface), The data communication device records this information, but does not perform other operations (step S302 of Fig. 3). Both the broadcast control platform 1 and the broadcast control platform 2 monitor the program stream. If the broadcast control platform 1 finds that the program 1 is illegally inserted and the illegal content occurs, the channel blocking command is sent to the data communication device, and the data communication device retains only the following outgoing interfaces for the multicast route corresponding to the program 1: The interface 1 to the broadcast control platform 1, the interface 2 to the broadcast control platform 2, and the interface 4 under the control of the platform 2. The interface 3 under the jurisdiction of the broadcast control platform 1 is deleted from the program 1 multicast routing out interface, and the user group 1 under its jurisdiction can no longer receive the channel program stream. However, the interface 4 governed by the broadcast control platform 2 is not affected, and the downstream user group 2 can also receive the program stream (step S304 of Fig. 3). When the broadcast control platform 2 finds that the program 1 is illegally inserted, it is necessary to block the downstream user from continuing to receive the program stream, and also sends a channel blocking command to the data communication device, and the data communication device corresponds to the program 1. Multicast routing, leaving only the following outbound interfaces: Interface 1 to the broadcast control platform 1, interface 2 to the broadcast control platform 2. The interface 4 governed by the broadcast control platform 2 is also deleted from the program 1 multicast routing out interface (step S304 of Fig. 3).
