Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The present disclosure provides a live broadcast processing method, which is used for processing a live broadcast under the condition that IPTV live broadcast content is tampered. Some embodiments of the live processing method of the present disclosure are described below in conjunction with fig. 1.
Fig. 1 is a flow diagram of some embodiments of a live method of the present disclosure. As shown in fig. 1, the method of this embodiment includes: steps S102 to S108.
In step S102, in response to tampering with the IPTV live content, a live multicast address is determined.
Different live channels may correspond to different multicast addresses, i.e. addresses of playing terminals of an IPTV, which terminals are, for example, televisions or set-top boxes. Live streams of live channels may be illegally tampered with allowing users to see illegal pictures. When the content of the live channel is found to be tampered, the multicast address corresponding to the live channel can be determined according to the storage data of the live channel in a background database (e.g., an IPTV platform database).
In step S104, a security indication packet is constructed from the multicast address. The security indication data packet includes a security signal.
The safety indication data packet can be constructed by imitating a live broadcast original data packet, namely the safety indication data packet can be equivalent to a forged live broadcast data packet. Therefore, the terminal can obtain the safety indication data packet while obtaining the original live data packet, and the destination address of the safety indication data packet is the multicast address. In some embodiments, the security indication packets are encapsulated using MPEG-2TS (Moving Picture Experts Group-2Transport Stream). A new specific format of MPEG-2TS packets is defined in this disclosure. The MPEG-2TS Packet is 188 bytes in length, and the security signal can be encapsulated in a PID (Packet ID) field in a 4-byte header. The safety signal may be set to a predetermined value, for example 0x1 FFF.
Furthermore, safety indication information can be set in the safety indication data packet, and the effectiveness and the accuracy of safety indication are further improved. For example, a Payload field (Payload, 184 bytes) in a security indication data packet encapsulated in the MPEG-2TS format is filled with security indication information for indicating that data of the IPTV live broadcast sent to the multicast address is not secure. For example, referring to table 1, in the MPEG-2TS packet, the PID field is filled with 0x1FFF, and a preset byte (for example, 13 bytes) before Payload is filled with security indication information Warning: stream instance, Payload remaining field is empty.
TABLE 1
In some embodiments, the layers of the security indication packet may be encapsulated in the following manner. The safety indication data packet encapsulation comprises the following steps from top to bottom: the encapsulation above the IP layer has the same encapsulation mode as the original data packet of the IPTV live broadcast; the destination address field in the IP packet header is set as a multicast IP address, and the source IP address can be set as a safety device, namely a sending device of safety indication information; a destination port number field of a User Datagram Protocol (UDP) header is set as a multicast port number, and a source port number is set as a port number of the security device; a payload type field of an RTP (Real-time Transport Protocol) packet header is set as MPEG-2TS, and the RTP packet header is optional; MPEG-2TS data packet, PID field is set as safety signal, Payload field is filled with safety indication information.
By encapsulating the safety indication data packet in an MPEG2-TS format, the safety indication data packet can be mixed in a live MPEG2-TS stream in an IPTV live broadcast end-to-end system for convenient propagation, and can not be lost due to forwarding of each link of an IPTV platform, so that the safety indication data packet can be obtained under the condition that a subsequent terminal plays an IPTV live broadcast channel.
In step S106, the security instruction packet is mixed into the IPTV live data stream and transmitted to the multicast address.
By mixing the safety indication data packet into the data stream of the IPTV live broadcast, the safety indication data packet can be obtained when a subsequent terminal plays the live broadcast channel to obtain live broadcast data.
In step S108, when the terminal plays the IPTV live broadcast, the terminal cuts off the IPTV live broadcast according to the security instruction packet.
When the terminal plays IPTV live broadcast, namely, when a live broadcast data packet is obtained, the terminal also obtains a safety indication data packet. The terminal analyzes the safety indication data packet, and cuts off IPTV live broadcast under the condition of acquiring the safety signal, and further can play the cushion broadcast picture which can be stored in the terminal in advance. Because the terminal directly cuts off the live broadcast, the live broadcast picture can not be played, and the problem that the last frame is displayed after the terminal cuts off the signal in the prior art is solved. And under the condition that the safety indication data packet also comprises safety indication information, the terminal corresponding to the multicast address analyzes the safety indication data packet, identifies the PID field, determines whether the payload field contains the safety indication information or not under the condition that the PID field is a safety signal, and cuts off IPTV live broadcast under the condition that the payload field contains the safety indication information.
One application example of the present disclosure is, for example, live content of a live channel a in X city is tampered, 239.93.41.78 is a multicast address of the live channel a in X city, the security device injects a security indication packet through a multicast routing protocol (e.g., PIM protocol), the multicast address is also 239.93.41.78, when encapsulating the packet, except for an IP source address and an MPEG-2TS packet structure, a reference live channel a is encapsulated on an IP layer, and the encapsulation manner is as follows from bottom to top.
IPV4 header, 20 bytes, Src IP (Source IP Address, Security device Address): 139.206.31.153, and Dst IP (destination IP Address): 239.93.41.78.
UDP header, 8 bytes, Src Port (source Port number, security device Port number) 8042, Dst Port (destination Port number) 5140.
RTP packet header: 12 bytes (Payload type: MPEG-II TS), and an RTP packet header is optional.
TS data packet: PID is 0x1FFF, Payload is filled with security indication information.
After the safety indication data packet is sent out, when a terminal such as a set top box watches a channel A, a rtp://239.93.41.78:5140 is pulled, the safety indication data packet is received, and a safety signal and/or safety indication information are obtained by analyzing the safety indication data packet, so that the picture is switched to the padded picture.
In the method of the above embodiment, in the case that the IPTV live content is tampered, a security indication data packet is constructed, where the security indication data packet carries a security signal. And the safety indication data packet is mixed into the data stream of the IPTV live broadcast and sent to the multicast address, and the terminal cuts off the IPTV live broadcast according to the safety indication data packet under the condition of playing the IPTV live broadcast. The safety indication data packet is mixed into the IPTV live broadcast data stream, so that the terminal can obtain the safety indication data packet while obtaining IPTV live broadcast data, the live broadcast is directly cut off by the terminal, the problem that the live broadcast stays in the last frame of picture is solved, the processing effect of the live broadcast after being tampered is improved, and the user experience is improved. In addition, compared with the prior art, the method has no relation with a platform and a network, does not need to be modified, and only needs to support a multicast protocol. Under the condition of multiple platforms and multiple network manufacturers, the purposes of reducing cost and improving efficiency can be achieved.
Due to the hierarchical architecture of the network, live broadcast data are tampered at different network nodes, the area ranges of affected users are different, in order to further improve the efficiency and accuracy of handling after live broadcast is tampered, users who are not tampered are prevented from being affected, the security equipment can be deployed to correspond to different network nodes, and the centralized management platform triggers the processing flow of the security equipment after live broadcast is tampered. Further embodiments of the disclosed live broadcast processing method are described below in conjunction with fig. 2A and 2B.
Fig. 2A is a flow chart of other embodiments of the live broadcast method of the present disclosure. As shown in fig. 2A, the method of this embodiment includes: steps S202 to S212.
In step S202, in response to the IPTV live broadcast content being tampered, the centralized management platform determines an area range and a multicast address affected by the tampered IPTV live broadcast.
The centralized management platform can determine which network node the IPTV live broadcast is tampered at and the range of the affected area when the content of the IPTV live broadcast is tampered. For example, a live broadcast may be tampered with in a BRAS (Broadband Remote Access Server), affecting users in a downtown area.
In step S204, the centralized management platform sends a processing instruction to the security device corresponding to the affected area range. The processing instruction may include a multicast address, and may also include information such as channel information of live broadcast.
As shown in fig. 2B, for an exemplary IPTV network architecture, the security devices include, for example, a Core security device corresponding to a metropolitan area network CR (Core Router), a BRAS (broadband access server), or an edge security device corresponding to a provincial center Router. The security device can set communication interfaces with the CR, BRAS and provincial center router respectively so as to send security indication data packets according to a multicast protocol in the following.
In step S206, the security device corresponding to the affected area range constructs a security indication packet according to the multicast address.
The safety indication data packet can also be constructed by the centralized management platform and directly sent to the safety equipment, and then sent to the multicast address by the safety equipment. The safety indication data packet comprises a safety signal and/or safety indication information.
In step S208, the security device corresponding to the affected area range sends the security indication packet to the corresponding network device.
That is, according to the area range affected by the tampering of the IPTV live broadcast, the security indication data packet is sent to a corresponding network device, where the network device includes, for example: CR, BRAS, provincial central router.
In step S210, the network device receives the security indication packet, mixes the security indication packet into the data stream of the IPTV live broadcast, and sends the security indication packet to the multicast address in the affected area range.
In step S212, when the terminal plays the IPTV live broadcast, the terminal cuts off the IPTV live broadcast according to the safety indication data packet, and plays the live broadcast screen.
The method of the embodiment does not need to modify the IPTV platform or the original network node equipment, and only needs the equipment to support the multicast protocol. Under the condition of multiple platforms and multiple network manufacturers, the purposes of reducing cost and improving efficiency can be achieved. Compared with the method for preventing the live broadcast data from being tampered by signing, encrypting, adding fields and the like in the live broadcast stream, the method of the embodiment better conforms to the relevant policy of the national radio and television department, because the radio and television department does not allow the modification of the live broadcast original data.
The method of the embodiment is suitable for IPTV live broadcast delivered in a multicast mode. The problem of global tampering and local tampering is solved through core security equipment and edge security equipment which are deployed at nodes such as an IPTV province center and metropolitan area networks CR and BRAS. Aiming at the problem of local range IPTV live broadcast tampering, for example, a live broadcast channel on a certain BRAS is tampered, a traditional method cuts off a live broadcast source stream, which is invalid for users in a region range corresponding to the BRAS, and the users in the region range corresponding to the BRAS can still receive illegal pictures, so that user experience is influenced.
In addition, the method of the embodiment adopts a multicast mode, has low overhead, is not influenced by the scale of IPTV terminal users, greatly reduces the concurrency pressure, relieves the processing burden, improves the processing efficiency and reduces the cost.
The present disclosure also provides a live broadcast processing apparatus, which may include the security device of the foregoing embodiment or include a centralized management platform and a security device, which is described below with reference to fig. 3.
Fig. 3 is a block diagram of some embodiments of a live processing device of the present disclosure. As shown in fig. 3, the apparatus 30 of this embodiment includes: an address determination module 302, a data packet construction module 304 and a security processing module 306.
An address determining module 302, configured to determine a multicast address of a live broadcast in response to tampering with a content of the IPTV live broadcast.
And the data packet constructing module 304 is configured to construct a security indication data packet according to the multicast address, where the security indication data packet includes a security signal.
