Description

Management execution platform constructed based on network video streaming computing method

Technical Field

The invention relates to the technical field of new media, in particular to cloud and big data analysis.

Background

The form of video services has evolved from analog television to digital television, from broadcast television services to interactive video services. The interactive video service only provides basic video service and value-added service at present, has low cost, and occupies too much bandwidth. The solution for the innovation of the interactive video service industry is a deepened business. With the development of economy and technology and the popularization of interactive video services, users put higher demands on usage patterns, functions and service quality. They wish to enjoy interactive video services (e.g., home, workplace, automobile) on various client devices (e.g., set-top boxes, laptops) anytime and anywhere. They want more video-based applications to easily manage and use their search. They want these applications to fully integrate and utilize different client devices, ensure a high standard of quality of service (e.g., fluency, high resolution video for video and applications), and at the same time provide personalized services. The current industry situation and the user requirement are applicable to heterogeneous client devices, and novel interactive video services such as diversified video application, service quality guarantee, personalized service provision and the like are provided.

We begin to introduce new types of interactive video services from the previous interactive video service model. It falls into two main categories: 1) a unified powerful client device is provided, and a user can select a service providing mode from a plurality of Internet service providers according to different service scales, service contents and service qualities of the Internet service providers. Canada and some other countries pass this mode of operation. This has the advantage of providing various options for the user and promotes competition between operators. Its disadvantages are that internet service providers operate independently, and it is too costly to deploy large-scale complete private networks, thus quality of service (QoS) cannot be guaranteed and their applications and services cannot be shared. 2) Only one network service provider has established a complete fiber-optic private network interactive video service in the entire area. The internet service provider should perform real-time monitoring and dynamic adjustment, collection, analysis and management of network conditions on all devices of the entire network and the cloud computing side, so that the quality of service is guaranteed. China, france and other countries use this mode of operation, where telecommunications, as the only internet service provider, provides a unified platform for integrating and managing value-added services, while other software companies, content providers and device providers, as internet service provider partners, develop and provide these value-added services and client devices based on the platform. The advantages of this mode of operation are: its guaranteed quality of service; it allows heterogeneous hardware (e.g., set-top boxes with different embedded chips) of a large number of client devices to an interactive web tv service, which attracts many different users with flexible capabilities and low-cost client devices. The user can enjoy value-added applications and services provided by the internet service provider and can communicate with the internet service provider, which is advantageous for promoting the popularization of the internet service provider service.

The operation mode of the new interactive network tv service tends to introduce the technical advantages of the internet and the pc to tv service, so to enhance interactivity and rich contents and service types, the google tv system and the apple tv system are the best representatives. An application store using the apple television system (see steve-lemma, schen-kelly, user interface, application management mobile device, apple shares, inc., US2009/0307105a1, 12 months 10 days, 2009) except for various value-added applications that manage the user's basic video services. It allows the user to search for target applications and keywords by category and decide to download the software, or not according to their introduction (per operating cost); other applications can still be used while downloading new applications; the downloaded application store helps their users to install them on their clients. This style of interactive video service has the following drawbacks: the user cannot use the application until the download is completed; finding out whether there is a reward before the user has to pay for the application; more importantly, it is inconvenient to update; the application runs entirely on the client, requiring higher performance and cost of the client device. Google television systems enable keyboard technology to be introduced into television control, increasing the interactivity and cost of client devices and the difficulty of operation, although most television users may be unaccustomed to complex operations like personal computers; it provides rich online video to TV users, realizes the diversity of TV content, but brings the insecurity of Internet.

The second mode of operation has advantages of first in quality of service, shielding heterogeneity of hardware devices and facilitating user access to the network. But the internet service provider platform only provides basic video services in this mode. This is a closed one that is difficult to integrate into diversified video content and value-added applications. Although the heterogeneity of the hardware devices and network connections of the shield to provide seamless switching between different client devices and other value added services, it does not take into account the set of real-time states and therefore cannot take advantage of this heterogeneity. Therefore, the platform still has a shortage of managing the whole dedicated network of the interactive network television, and further improvement of the service quality is required.

It is therefore an object of the present invention to provide a second mode for use in interactive network television to establish a management and execution platform. The method makes full use of the special network and heterogeneous equipment of the telecommunication and simultaneously utilizes the advantages of the existing novel interactive video service. The platform can help business partners to develop and conveniently integrate various video resources and value-added applications. Interactive network television can easily manage these resources and applications, the network status, and the client devices. The user can retrieve and transparently run the new application. More importantly, the platform can shield heterogeneity of hardware devices and collect and calculate fused real-time state data.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention provides a computing method of network video of streaming media, and a platform supporting management and execution of network video application programs is constructed.

The technical scheme adopted by the invention is as follows: based on private networks of telecommunication companies over a convergence of three networks. An executable platform directly installed on a client is created for telecommunication users, and the platform can not only enjoy basic interactive network television video service, but also run streaming media network video applications, such as video-assisted electronic commerce, electronic learning, electronic medical treatment and the like. The invention provides a management platform for operators to collect data for analysis. This platform consists of two parts: the system comprises a cloud consisting of various computers, a server, a data storage device and a client. The client comprises other mobile devices such as a set-top box, a personal computer, a tablet computer and the like, only a small kernel is pre-installed, and the kernel can be loaded for customization according to the state of the client and the configuration of a bootstrap program. The kernel includes application manager media middleware stream scanning techniques methods for masking hardware device heterogeneity, interfaces for dynamically loading and managing applications and providing general video application development, synchronization modules and their associated buffer manager modules. According to the stream scanning technique of the present invention, the application is also divided into two parts: the cloud and the client, the main computation executed in the cloud and the buffer of the client execute the application program and download at the same time, so the method allows the client to have low-performance equipment and is convenient for the installation, running and updating of the executable program. Thus, resources and advantages of the cloud, the client and the network are fully utilized. The cloud computing has strong computing power and storage equipment, can effectively assist the operation of client programs, collect and analyze network states, transmission conditions, states of clients, user information and the like, and then make timely adjustment according to the information.

Compared with the prior art, the invention has the beneficial effects that: (1) the method fully utilizes a special network with high bandwidth and high reliability, collects the running states of the client and the cloud computing end codes, the state of network transmission and the service quality related to other data, and carries out statistical analysis on the operation history and social information of the user. When the client requests a new service, the cloud selects a better method to provide a better service based on the collected data; the cloud monitors all the collected data and adjusts the service mode accordingly. Therefore, the main reason that the method can provide the network video service with the quality of service function is that the quality of experience of the user is influenced and the method cannot be realized in the existing interactive video service.

(2) All applications and resources in the described method have to be integrated through the platform and transported over the dedicated network of communication. The client executes the buffered application program and clears the buffer area after the application is completed. Such a mode of operation improves the security and stability of the platform. The cloud performs various types of data and states for real-time stream collection and monitoring, and assumes a large amount of computation and storage states, allowing the requirements of the client and server to be restored to a specified state, enabling the platform to be controlled and safely managed. The application and resources are integrated and managed through a unified platform. The method provides a remote control mode, wherein the cloud end can control the client end through the network, and the mode is beneficial for a network service provider to manage, control the operation of the client end and bring possibility for large-scale test and data collection. All in all, the platform based on this method is secure, manageable and controllable.

Detailed Description

The following describes in detail a specific embodiment of the present invention with reference to the drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

The invention provides a method for calculating a network video of streaming media. The method is characterized in that the heterogeneous equipment and the network thereof run strong interactive service capability on low-cost embedded equipment, and provide capability integration of interactive video service quality of support service. The management and execution platform can support network video application construction based on the method; this platform is secure, manageable, controllable.

As shown in fig. 1, the present invention is mainly applicable to triple play. The three networks refer to a digital communication network represented by a conventional telecommunication network represented by a telephone network (including a mobile communication network) through the internet and a broadcast television network represented by a cable television. The invention is used on the private network of a single deployed internet service provider; the three networks are integrated, so that resource sharing and network service are realized, and repeated construction is avoided. The center of the private network is a core server of a cloud; the middle layer 102 is a regional node layer; the outermost layer 103 is an edge node layer; the client device connects to the private network through the edge node 104 using different access methods (e.g., CABLE106, WLAN107, 3G 108); and interactive video applications and other services are distributed at the cloud client by the layer nodes. Note that the private network is connected by optical fibers and the network bandwidth is gradually increased from the outside inward as the thickness of the network cable 105 in fig. 1 changes, taking into account load considerations.

Because one characteristic of the invention is: the system can shield heterogeneity of hardware devices and networks, and users can use network video applications (video-assisted e-commerce, e-learning, e-medical treatment and the like) operated by different client devices (including a set top box 110 of a television, a PC111 and a portable personal computer 112) to be in different positions. A typical use case shown in fig. 1 is: a user runs a videophone at his company using the computer 113, then watches the video-on-demand using his own tablet on the way home, and continues to watch the video or execute other video applications on the television after home.

Fig. 2 shows the protocol layers of this platform, connecting the private network of telecommunications through the cloud and the clients.

In terms of cloud computing, the platform layer L202 sits at the application layer L201, above the operating system driver layer L203 and the hardware layer L204. The advantages of a large data storage device and a clustered powerful central processor hardware layer that provides a number of modules including-application integration, process scheduler, collection, streaming servers and streaming tools. In detail, application integration provides interfacing application integration and management, such as using streaming tools to convert storage locations encoded into streaming media, records, and configure interfaces for charging modes. The streamer changes the application's executable and the media file stream and adds the same clock-referenced time stamps. Various streaming servers send streaming data to clients including streaming servers, streaming server application code, and streaming server computation results. The streaming application code server sends a series of executable code segments. And the cloud computing end code of the process scheduling program operated by the application program stores the real-time storage space of the computing result, informs the streaming media server of the computing result, and sends the result to the client in real time. The state collection module collects information of network service quality, client operation, video and audio service quality and the like from the cloud and the client simultaneously, and the information of the services is adjusted and optimized in real time by the streaming media server.

At the client, the platform layer L206 sits at the application layer L205 and includes a driver layer L207 and a hardware layer L208 that complain of an operating system. It not only integrates various underlying heterogeneous hardware, but also provides a boot program and kernel (including application manager, synchronization and buffer manager, and streaming middleware). The boot loader loads the kernel according to different configurations and different middleware modules according to different configurations, and provides a running basic environment module. For example, a bootloader of a client in a high bandwidth network environment may only need to load a doghouse universal player and adapter, depending on the configuration. Therefore, the user can customize the client according to the client state of the user, and the kernel is small and powerful all the time. The buffer manager stores and manages various streaming media resources transmitted from the cloud. And the application program sent by the application manager executes the request of the user to the cloud, executes the stream executable code segment and loads the dynamic link library by the on-demand stream media middleware. The synchronization module synchronizes the execution code segment and the media in the buffer.

In fig. 2, this platform defines four types of general interface protocols, which are respectively a resource integration interface T209 and a cloud-side client T210, an application programming interface T211 and a hardware integration interface T212 on the hardware integration interface. These interfaces allow for an integrated and easy-to-manage, rapid platform for multiple service providers, content providers and hardware providers with internet service providers.1) an integrated interface T209 at cloud resources: located between the cloud application layer L201 and the cloud platform layer L202. The application integration interface and platform that can be invoked by the network video application developed by the service provider are integrated. For example, the service provider may stream an executable program into the media and specify a charging mode via an interface of the invoked application integration. 2) Hardware integration interface at cloud T210: located between the cloud platform layer L202 and the cloud operating system driver layer L203 and the cloud hardware layer L204. It provides the basic hardware and interface to the operating system adaptation layer, including database access, input-output port access, etc. 3) The application programming interface T211 is at the client: it is located between the client's application layer L205 and client platform layer L206. And the developer calls an interface of the layer according to different service requirements, interacts with the cloud and develops diversified network video application. This layer of interfaces like the universal player and FEC (forward error correction) interface is universal, complete and scalable. 4) At the client is a hardware integration interface T213: it is located in the client platform layer L206 and the driver L207 of the underlying client operating system, the client hardware layer L208. It provides an interface to the basic hardware and adaptation layer of the operating system, aiming at blocking heterogeneity on different types of hardware platforms and operating systems from different manufacturers. Since this platform is mainly directed to network video applications, these interfaces only include the basic functions required by such applications, such as decoders for media files, network connections, input output access interfaces. They are of few types and convenient to transplant.

The basic process of using the client method by the user is as follows: the user opens the client, logs on to the internet service provider portal, and the client displays a desktop listing a large number of network video applications. The user may directly select an application to execute it (see fig. 4 and execution of the following specific application), or enter "application recommendation" as shown in fig. 3:

1) step 301; the method allows a user to search for applications he desires by means of classification and keyword entry.

2) Step 302: the cloud computing form qualification application and related data comprise introduction, price, evaluation and the like. Because in the processing result, the cloud end utilizes a large amount of related information collected before, such as user preferences, operation history, suggestions of friends and the like. The user can obtain more satisfactory search results.

3) Step 303: the user's decision to run application 1 in the low cost mode would reduce the cost by $ 0.05, the low average cost of the application encourages him to try more new applications, he does not worry about spending too much money on the application.

4) Step 304: the streaming media executable code segment, the video and audio segments and the code of the server side are sent to the application 1 by the cloud computing, and the client side receives the execution result of the request. Receiving these segments, the client stores them in buffer M3U8 and immediately begins execution. He does not need to wait for the download to be completed nor install and manually update them. The cloud will always participate in and assist the execution of each program, so it allows low performance client devices, and can reasonably adopt a charge per execution mode.

5) Step 305: and the client sends various current states to the real-time property of the cloud end by the application program running at the same time. The cloud adjusts the method based on the data service to ensure the quality of service. For executing specific states, please refer to FIG. 5.

6) Step 306: the client will end execution when the buffer is cleared, so the user does not need the uninstalled program and manage the storage space of the client. If the user wishes to continue using the application he may choose to add it to his favorite and then the application icon will appear on his desktop without the step of performing the next search at S301. For his favorite application, the cloud records his chosen configuration and his last running state, so he can go to the program directly or continue the last year execution state.

7) Step 307: if the user decides not to use an application, it simply needs to be deleted from the favorites or desktop. Even when the display on the desktop is from the user login, because the different client devices as the user favorite data is stored on the server are the same, the same application on each different client device can execute the application that he prefers on the different client devices without installing it; every time the latest version of the application from the network is executed, manual updating is not necessary.

In a word, compared with the traditional application program store, the using method greatly simplifies the using and managing processes of the client equipment and improves the manageability of the cloud to the client equipment; real-time status reporting and service adjustment ensure quality of service and quality of experience; the economic burden on the user is reduced per operating cost, and the streaming scanning technology method allows the client to have lower operating quality and highly interactive network video application.

Fig. 4 shows the logic flow of the method, including a cloud D401 and a client D402 connected to a private network of telecommunications. A plurality of powerful central processors and cloud storage data, such as video and audio files, executables for networked video applications, sufficient storage space to execute the state of the applications in cloud D401. After the client D402 holds the requested application, it receives data from the cloud executable code and so on. The process of the method based on the streaming media is as follows:

1) the first step is as follows: at the cloud computing end D401, the streaming tool converts all network video applications and media file streams from different content providers, i.e. it divides the executable program of the application program into multiple executable code segments, or converts video and audio files into streams. The process of data flow of the executable program is: first, all executable code is split into client code and cloud code, and then each executable code segment will be time stamped with the same reference clock (typically including a start time and an end time).

2) The second step is that: the user selects a web video application on the user interface and the application manager then sends the request to cloud D401.

3) The third step: after receiving the request, the process scheduling program caches the client code and the media data to the client, and the streaming media server is in a corresponding real-time streaming media form

4) The fourth step: the client stores the executable program segment in the buffer, and then the streaming media middleware loaded by the application manager provides the executable code for execution of the runtime environment according to the dynamically linked library of configuration information of the application (the configuration information being specified by the application developer).

5) The fifth step: the executable code, video and audio files, synchronized by the application manager, pass through the synchronization module in real time and execute the prioritized ones of them to produce the corresponding application process 1 (client) invoked by the application.

6) And a sixth step: application process 1 (client) may invoke execution, some interface to streaming media middleware, such as a universal player, forward error correction. Application Process 1 (client) can also call the decoder interface to decode the streaming media files in the buffer and display them on the display

7) The seventh step: and in the application program process 1 (client), according to the operation of a user, the computing state is updated to acquire a module for collecting the real-time state of the cloud, so that joint computing and the cloud are provided. And these data can facilitate data mining in the future.

8) Eighth step: the process scheduler of D401 on the cloud is a client of the executable code segment sent by the streaming application code server. Meanwhile, the cloud end executable code segment is executed to generate a processing corresponding to the application process 1 (server), and the calculation result is sent in the form of real-time flow of the application process 1 (client) of the application program of the streaming server through the calculation result.

9) The ninth step: when application process 1 (client) completes execution, it deletes the cached and cloud computing-productive media files and notifies the application manager.

10) The tenth step: the executable code segment in the buffer is cleared immediately after the application manager is enabled.

In the above description, the principles of the media file and code synchronization module: if the starting time of the code segment is larger than the time of the current reference clock, waiting to run at the code segment until the reference clock reaches the starting time; the execution priority of a code segment is increased if the start time of the code segment is smaller than the time of the current reference clock. In addition, because the reference clocks of the servers are the same, the module can ensure the synchronization of video, audio and codes when the servers convert the codes of the video and audio.

Therefore, the network video computing method of the streaming scanning technology mainly provides manageability and synchronicity. The client may not directly store and manage the network video applications, they may be executed without waiting for download, while the dynamically loaded client-executable code segments may run them from the cloud client buffer.

Although there is a patent "execute code segment and uninstall for download mode stream", in this method, a lot of video decoding is performed on the client side properly, and the powerful cloud is suitable for performing the computation, because we focus on network video application, the client device is a low performance set-top box, and the network connection is the telecommunication 100 million private network. The executable code corresponding thereto is divided into server code and client code for calculation and decoding. A portion of the executable code segment is sent to the client to reduce the computational complexity of the client. Joint computation of the server and the client does not create a burdensome network video application because of the sufficient bandwidth and transmission of executable code.

The manageability of the platform is mainly embodied in that the real-time all aspects of the cloud end collect information such as states. These data have mainly the following applications: the cloud end analyzes the collected data, so that an operation state diagram of a client can be established, the client based on the collected data can be managed, and better service is provided for the user; the cloud can timely guarantee the safety of the whole network platform when abnormal data is detected.

The method collects and manages four types of resources, as shown in fig. 5: 1) content resource T501: video, audio, images, web pages, etc. The platform allows access by a plurality of content providers; it also allows network resources to be integrated into the user's platform. The platform collects the same resources (e.g., the same film) with different attributes (e.g., storage format, encoding format, and resolution); it selects the appropriate type based on the client and network 2) state of the server state T502: including the current load, location and round trip time delay of the server, remaining bandwidth, remaining central processors, etc. The platform monitors the status of the server. When a client requests a service, the platform automatically selects the best server based on the availability of multiple servers in these regions. When one server fails, the platform can restart the server or transfer all services to other servers to ensure transparent and smooth execution of the client application program. 3) Client state T503: the platform collects and monitors the client state time in real time to prepare for recovering the client state; at the same time, a method of service according to these states to guarantee quality of service is adjusted. 4) User information T504: such as the user's preferences, the user's social network relationships. The platform suggests personalized services to users and allows users to share and social network recommend services and videos to improve user experience.

The method has the characteristics that: it can guarantee the service quality related to the interactive network video application which the platform builds in the method to run. The service function is quality by the following measures:

1) a single internet service provider specific video network is used. The method adopts a video and audio multicast mode to improve the transmission efficiency and reduce the possibility of backbone network congestion. The service quality of network transmission is ensured.

2) Finally, the overall quality of the service is ensured to be configured to a special network environment, and the overall management and scheduling mechanism of the service quality is realized. The quality of the service mechanism of the 'end-to-end' comprises error control (such as forward error correction), the real-time monitoring of the client state cloud and the service quality, the service mode is adjusted in time, and the client can deal with the instability of transmission by using a streaming buffer.

3) All data transmitted in the two modes, such as the application fields, the media files, the cloud computing results and the streaming media fed back by the clients, ensure the service quality of the data. The client codes and the calculation results of the server synchronously cooperate with each other according to a time axis using the same reference clock to form a complete network video application, so that the quality of the network video application of the service function is realized.

As an executable platform, the security of the platform is guaranteed in the following aspects of integrating with different networks and various resources:

1) the cloud end is connected with the client through a telecommunication private network and is difficult to be invaded and connected;

2) for example, all resources of the network video cannot be directly sent to the client, and are required to be integrated and checked through the platform;

3) all applications need to verify the platform before they are added for user selection. The client has no external storage device, so various malicious programs cannot be stored locally at the client without authorization. Each execution is the latest version downloaded directly into the buffer, and most of the computation runs in the cloud. Even when an abnormality occurs, the system becomes clear again after restart;

4) the collected and stored states in the platform can be transmitted to the server and the client in real time, so that abnormal states and errors can be detected in time;

5) the user's behavior and social network are analyzed at the platform so it can identify anomalous actions at time.

The ease of scalable deployment of this platform is shown below: the integrated interface of the service provided by the system is convenient for adding new functions without influencing other people; only the client on the kernel platform is preassembled, so that the deployment is easy; the application program is downloaded to the buffer area to be executed each time so as to ensure that the application program is updated in time; the cloud computing type expansion platform can cope with expansion of the platform in a server; the platform collects client and server information at time to ensure load balancing, thereby facilitating user management.
