Detailed Description
To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is obvious that the described embodiments are some, but not all embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In this application, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In the present application, 5G refers to a fifth generation mobile communication technology. 5G is the highest peak of the current mobile communication technology development. 5G is a higher demand for mobile communication on the basis of 4G. 5G has advanced mobile communications in many areas, such as speed, bandwidth, and latency. The highest data transmission rate of 5G can reach 10Gbit/s, and the lowest network delay can reach within 1 millisecond. The 5G international standards organization 3GPP defines three major directions for 5G application scenarios, namely Enhanced Mobile Broadband (eMBB), Massive internet Of things (MMTC), and Ultra Reliable Low Latency Communication (URLLC). Currently, 5G applications can be generally divided into two broad categories, general and industrial applications respectively. The universal application mainly comprises 5G-based ultra-high-definition videos, 5G-based VR/AR, 5G-based internet unmanned planes, 5G-based wireless robots and the like. The industrial application mainly comprises the application of 5G in the industrial fields of new media, industrial internet, car networking, remote medical treatment, smart cities, rail transit and the like.
The Private Cloud referred to in this application refers to a Virtual Private Cloud (VPC), also called a Private network. The private Cloud is a virtual network environment which is constructed by an Elastic Cloud Server (ECS), can realize isolation among users and can realize autonomous configuration and management of the users. The use of the private cloud may improve the security of resources on the user cloud. The user can define security groups, IP address segments, bandwidth, etc. network characteristics in the VPC. Or, the user can manage and configure the internal network through the VPC to perform safe and rapid network change. In addition, the user can also realize interconnection between the VPC on the cloud and a traditional Internet Data Center (IDC) through connection modes such as a Private line/Virtual Private Network (VPN)/General Routing Encapsulation (GRE) and the like, so as to construct a hybrid cloud service. The private cloud has the advantage that security isolation can be performed between different tenants. Meanwhile, the private cloud can also configure the Network as needed based on Software Defined Networking (SDN) technology. Furthermore, the tenant of the private cloud can connect the VPCs in the private cloud and the public cloud through technologies such as VPN, so as to form a cross-region hybrid cloud resource pool.
In the present application, a Content Delivery Network (CDN) is an intelligent virtual Network constructed on the basis of an existing Network. The construction of the CDN is implemented by means of edge servers deployed in various places. The CDN can enable a user to obtain required content nearby through load balancing of the central platform, reduce network congestion and improve the access response speed and hit rate of the user. With the advent of high definition and ultra high definition (4K) video, over a million parts of content are transmitted each day over a network to user terminals. Fast-update video products, and the video demand for high-quality video experience, place higher demands on network concurrent processing power and network capacity. The content distribution network of the traditional chimney framework has difficulty in meeting the requirements of various types of content management and distribution. In order to solve the bottleneck problem caused by streaming media data in a backbone network, a CDN technology is integrated. The CDN combines technologies such as a monitoring and intelligent scheduling mechanism, an intelligent routing strategy and service quality monitoring by virtue of a high-quality node network, so that a user can enjoy high-quality video viewing and web browsing experience on various terminals.
Streaming media (streaming media) is also called streaming media or streaming mode. In streaming media, multimedia files such as video and audio files can be formed into one or more data packets by a special compression method. The data packet can be transmitted to the user terminal by the server, and the data packet usually maintains consistency, continuity and real-time property when data is transmitted. The traditional non-streaming playing mode needs to download the whole file before use and store the file locally before playing. The streaming media can be played without waiting for the whole file like non-streaming playing, and can be watched only by waiting for enough starting data. The rest data will continue to be downloaded and played one by one. When media files are transmitted through a network, a compression algorithm is generally adopted to compress original data, so that the dependence on network bandwidth is reduced, and domestic common Live broadcast protocols include a Real Time Messaging Protocol (RTMP), a dynamic code rate adaptive algorithm (HTTP Live Streaming, HLS), HTTP-FLV and the like. The RTMP is a proprietary protocol developed by Adobe for audio and video data transmission between a Flash player and a server. Meanwhile, RTMP is also a plaintext protocol working on TCP, a port 1935 is used by default, and the network delay is relatively low and is generally 1-3 s. Flv (flash video) is another video format introduced by Adobe corporation, which is a streaming media data storage container format transmitted over a network. The FLV video format consists of The FLV Header, The FLV Body and other tags, The suffix of The encapsulated file is FLV, and The loading speed is very high. The HTTP-FLV encapsulates streaming media data into FLV format, and then transmits to the client through HTTP protocol. The HLS differs from the above streaming media protocol most in that it does not request a complete data stream at once. HLS is to cut streaming media data into continuous short TS small files at the server, and access the TS files sequentially through M3U8 index files. Therefore, the client only needs to play the files acquired from the server in sequence continuously, and therefore audio and video playing is achieved. The HLS has the advantages of high performance, network delivery support through HTTP transmission, good CDN support, self-contained multi-code rate self-adaption, capability of penetrating a firewall, and low real-time performance, high delay and basically delay more than 10 s.
With the development of communication technology and internet technology, the network live broadcast industry is rapidly emerging. The network live broadcast has rich content and powerful expression mode. The "live broadcast + X" mode is also rapidly permeating to various vertical industries along with the rise of network live broadcast. Such as web lessons live, shopping live, etc. With the continuous development of the network live broadcast industry, the requirements of users on live broadcast platforms are also improved. When a user watches the live network broadcast, the live network video needs to keep high definition so as to improve the watching effect. When the anchor broadcasts the live broadcast on the network, the network which needs the live broadcast keeps high reliability, and avoids the influence on the live broadcast effect caused by the blocking due to the excessive number of people. Meanwhile, no matter the anchor or the user, the live webcast is required to be kept in a low-delay state, so that poor experience effect caused by interaction delay is avoided. Currently, live webcasting is generally realized by using a public cloud live platform. After the front-end equipment finishes the acquisition of the video signal, the front-end equipment uploads the video signal to a server of a public cloud. When the user needs to watch the network live broadcast, the user terminal requests the server for the video signal, and the network live broadcast watching is realized. However, live broadcast is performed by using a public cloud live broadcast platform, and the problem of poor data security exists. In addition, because data among different operators cannot be communicated with each other, the problem that user access is limited in a single-line machine room of the operators exists.
In addition, because direct interconnection and interworking between different operators cannot be achieved, the machine rooms of the operators are usually connected by a single line. Under the condition of single wire, the IDC machine room and the server are accessed by a single operator line, and the access response time delay fluctuation of the cross-operator is large. The prior art utilizes border gateway routing protocol (BGP) to transport data and information between different host gateways, the Internet, or autonomous systems. BGP is a Path Vector Protocol (PVP) that maintains paths to different hosts, networks, and gateway routers and determines routing decisions based on it. In order to solve the problem of interconnection between a single-wire machine room IDC network and other operators, a common BGP machine room is accessed with a mixed bandwidth, an IP of one line is mapped to an IP of the other line, and then the fastest line is automatically selected for the operators by means of a program, so that reasonable distribution of cross-operator access is realized. However, the BGP machine room scheme has the disadvantage of high capital and construction cost.
To the problem, the application provides a high-definition live broadcast system based on mixed cloud. The source station system of the live broadcast service built by the private cloud service source station is used. The Private Cloud service source station can provide functions of a uniform Private network (VPC), an elastic Internet Protocol (IP), Server Load Balancing (SLB), data storage and the like for live broadcast services. Meanwhile, the private cloud service source station can provide security guarantee for video data through modules such as a private cloud security pool firewall, an intrusion prevention system and security audit. By using the private cloud service source station, the advantages of private cloud environment resource exclusive sharing, data isolation, safety, stability and the like are fully exerted. The method and the device also use the public cloud service source station to build a stream media forwarding mechanism, so that the playing files can be rapidly distributed in a downlink mode through the public cloud service source station. According to the method and the device, a push-pull stream multi-link backup mechanism and a flexible transcoding mechanism of the video are constructed by building a high-definition live broadcast system of a mixed cloud based on a public cloud service source station and a private cloud service source station. The mixed cloud-based high-definition live broadcast system is used, so that the problem of downstream edge acceleration of service data of the private cloud system is solved, and the problem of bandwidth access of a private cloud platform to different regions and different operator networks is solved. The application also combines a 5G network and Mobile Edge Computing (MEC) to obtain the 5G node. The 5G node can further reduce network time delay, and meets the network requirements of high-definition video wireless return under various application scenes such as fixed-point live broadcast, walking broadcast and the like. The 5G node is used in the high-definition live broadcast system, and diversified live broadcast scenes such as 5G +4K/8K live broadcast, AR/VR live broadcast, holographic interactive live broadcast and the like can be met.
The high definition live broadcast system based on mixed cloud that this application was used compares with the ripe public cloud live broadcast platform in the market, can realize the data intercommunication of public network and private cloud private network to ensure functions such as video transmission, commentaries on classics push, transcoding, storage, can guarantee to a great extent that live broadcast platform resource is exclusive, data isolation, safety and stability.
Meanwhile, the public cloud service source station is used as a supplement scheme of the private cloud architecture of the operator, and the public cloud service node is used as a transmission pipeline. The streaming media signals can be transmitted to the public cloud service node through corresponding operator bandwidths, and then the public cloud service node forwards the streaming media signals to the private cloud internal live broadcast system through the communication bandwidth. Meanwhile, the distribution acceleration mechanism of the invention adopts a CDN framework fusing multiple manufacturers, further optimizes the problem of downstream edge acceleration of the private cloud system service data, and realizes an optimized line strategy of multi-mode switching at the playing front end.
In addition, in the application, the private cloud service source station constructs a push-pull stream multi-link backup mechanism and a flexible cloud transcoding mechanism based on three protocols of RTMP, HLS and HTTP-FLV. The public cloud service source station adopts a transcoding suppression strategy to adjust the frame-to-frame ratio (width and height) and the frame image resolution of the streaming media, and solves the problems of live broadcast blockage caused by unstable network environment and inappropriate front-end equipment.
In addition, the 5G node is used, and the 5G network is combined in practical application, so that the network delay is further reduced. The high-definition live broadcast system can meet the live broadcast requirements of multi-scene fusion such as fixed/walking interactive live broadcast, AR interactive live broadcast, holographic interactive live broadcast and the like. Experimental tests show that in the collecting, editing and broadcasting process, 5G network and RTMP protocol stream are used for manufacturing in the two links of collecting and editing, the time is 1-2 seconds faster than that of only using WIFI and 4G wireless networks, and the time is about 10 seconds faster than that of real-time stream in an M3U8 format using WIFI and 4G wireless networks and HLS protocols. While the use of 5G nodes is a combination of 5G and MEC. The 5G node can further reduce network time delay and has good application value for remote production and broadcasting in different places in actual production and the like.
The technical solution of the present application will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 1 shows a schematic view of a live scene provided in an embodiment of the present application. As shown in the figure, in the live broadcast process, three parts, namely front-end equipment, a high-definition live broadcast system and a user terminal, are mainly involved.
The front-end equipment is live broadcast equipment used by the anchor. The front-end equipment can be equipment for acquiring video signals, such as a high-definition/4K camera, a VR camera, screen recording equipment, a microphone and the like. The video signal collected by the front-end device may specifically include a high definition/4K signal, a VR signal, an AR signal, a mobile phone plug flow signal, a 5G return signal, a microphone audio signal, a Data Direction Register/Graphics form Express (DDR/GFX), a Joint Photographic Experts Group (JPEG) format picture, and the like. The front-end device may encode the video data into a streaming media signal, i.e., a video signal, after the acquisition is completed. And the front-end equipment uploads the video signal to a high-definition live broadcast system. And after the high-definition live broadcast system acquires the video signal, transcoding the video signal into a playing file. The playing file can be a streaming media playing file in a TS and M3U8 format. The high-definition live broadcast system can distribute the playing file to each edge node of the high-definition live broadcast system. When the user terminal requests the live broadcast system to watch the live broadcast, the high-definition live broadcast system can select edge nodes nearby according to the user terminal and push the live broadcast file to the user terminal. And after receiving the live broadcast file, the user terminal plays the live broadcast video by using the broadcast file to realize live broadcast watching.
Fig. 2 shows a schematic structural diagram of a hybrid cloud-based high-definition live broadcast system according to an embodiment of the present application, and as shown in fig. 2, the hybrid cloud-based high-definition live broadcast system 10 according to the present embodiment may include: a private cloud service source station 11 and a public cloud service source station 12.
The private cloud service source station 11 is configured to acquire a video signal, transcode the video signal according to a preset transcoding rule, and obtain a play file, where the play file is a streaming media play file obtained after transcoding the video signal.
In this embodiment, the front-end device acquires the obtained video data. The signals included in the video data are typically pictures and audio. In order to upload the picture and the audio, the front-end device may convert the video data into a video signal and upload the video signal. The video data collected by the front-end equipment is processed by an encoder (a software/hardware encoder) to obtain a video signal. The video signal may be transmitted in a real-time signal stream of a network protocol such as HTTP, RTMP, UDP, RTSP, and the like. The video signal has the transmission characteristics of large code rate fluctuation range and higher requirement on the self-adaptive capacity of the player.
The data transmission between the front-end device and the high-definition live broadcast system 10 may be implemented based on a Real Time Messaging Protocol (RTMP). After acquiring the video signal, the high-definition live broadcasting system 10 feeds the video signal back to the private cloud service source station 11 through the RTMP in real time. The private cloud service source station 11 calls a preset transcoding rule pre-stored in the local service to transcode the video signal into a playing file. The preset transcoding rule may be an HLS slicing algorithm. That is, the private cloud service source station 11 transcodes the video signal into the play file using the HLS slicing algorithm. The playing file may be a streaming media playing file in a TS and M3U8 format.
The public cloud service source station 12 is configured to distribute the play file to the user terminal in a downlink manner.
In this embodiment, after the private cloud service source station 11 completes generation of the play file, the play file is sent to the public cloud service source station 12. After receiving the live broadcast request of the user terminal, the public cloud service source station 12 distributes the broadcast file to the user terminal in a downlink manner according to the IP address of the user terminal. After the user terminal receives the playing file, the user terminal can realize live broadcast watching through the playing file.
When the public cloud service source station 12 distributes the play file in a downlink, the configured transmission protocol may include one of an RTMP, an HLS, and an HTTP-FLV. The public cloud service source station 12 selects one transmission protocol from the above transmission protocols to complete the configuration of data real-time transmission.
In one example, after acquiring the video signal, the high-definition live broadcasting system 10 may further send the video signal to the public cloud server source station 12, and the public cloud server source station 12 distributes the video signal to each user terminal according to a live broadcasting request of the user terminal.
The high-definition live broadcast system based on the hybrid cloud comprises a private cloud service source station and a public cloud service source station. And after the high-definition live broadcast system acquires the video signal, the video signal is sent back to the private cloud service source station through the RTMP in real time. And the private cloud service source station calls a preset transcoding rule pre-stored in the local service to transcode the video signal into a playing file. The preset transcoding rule may be an HLS slicing algorithm. And after the private cloud service source station completes the generation of the playing file, the playing file is sent to the public cloud service source station. And after receiving the live broadcast request of the user terminal, the public cloud service source station distributes the broadcast file to the user terminal in a downlink manner according to the IP address of the user terminal. In the application, through using the private cloud service source station, the resource exclusive share of a high-definition live broadcast system is guaranteed, the data isolation of live broadcast services and other services is guaranteed, and the safety and the stability of video signals are improved. Meanwhile, the playing file is transcoded in advance by controlling the video code rate and determining the transcoding strategy, so that the time delay of the user terminal is reduced, and the user experience is improved. In addition, this application has still avoided the three-way problem that the unable intercommunication of operator data leads to through the combination use with private cloud service source station and public cloud service source station, improves video signal's transmission efficiency, further reduces the time delay, improves user experience.
Fig. 3 shows a schematic structural diagram of another hybrid cloud-based high-definition live broadcast system according to an embodiment of the present application, and based on the embodiment shown in fig. 2, as shown in fig. 3, the hybrid cloud-based high-definition live broadcast system 10 of the present embodiment may include: 5G node 13.
The 5G node 13 is configured to send the video signal uploaded by the front-end device to the private cloud service source station 11 through a 5G streaming media.
In this embodiment, the front-end device realizes fast uploading of the video signal through the 5G node. Wherein the 5G node may include a 5G network and an MEC. The MEC is connected with the 5G base station, and a 5G streaming media private network channel from the front-end equipment to the private cloud service source station can be constructed. The 5G streaming media private network channel is used for realizing the data security intercommunication between the public network and the private cloud service source station, so that the video transmission efficiency is improved, and the security of video signal transmission is further improved.
The public cloud service source station 12 may include: a dispatcher 121, an edge node 122. The dispatcher 121 is configured to determine an edge node for downlink distribution according to the user terminal. The edge node 122 is used to implement downstream distribution of downstream files.
In this embodiment, the public cloud service source station 12 may specifically include two data processing nodes, namely a dispatching desk 121 and an edge node 122.
The edge node 122 is a CDN edge node deployed in each region for the public cloud service source station. The front-end device selects the edge node 122 nearby, and the video signal is uploaded. The proximally selected edge node 122 may be the edge node closest to the head end device. Alternatively, the edge node 122 selected nearby may be an edge node that is free within a certain range from the front-end device. Alternatively, the edge node 122 selected nearby may be the optimal edge node selected by integrating the distance and the busy degree of each edge node 122. After the edge node 122 acquires the video signal uploaded by the front-end device, the edge node 122 may push the video signal to the dispatcher 121.
The edge node 122 may also be used for distribution and acceleration of the playing file.
