Streaming media solution based on cloud computing for regional content fusion

As the foundation of education is still relatively weak, the overall level is not high, the national cities, counties and regions of education resources exist uneven development status. In the final analysis, the imbalance of educational condition (hardware) and teacher level (software) is very different between county, town and school. Because of the unbalanced educational resources, the fever of school choice has intensified, the countryside is choosing the city, the county is choosing the town, and the weak school is choosing the strong school. To guarantee the fair development of education, we should promote the balanced development of educational resources.

How can we make full use of educational resources and reduce the imbalance of educational resources between urban and rural areas and between schools, so that all students can enjoy the right to fair education? Cloud computing technology provides sufficient and effective technical support and service guarantee for constructing regional education public service platform.

3. To promote school resources open: Through the cloud computing platform for schools to establish a virtual office and teaching portal, for students, teachers, parents to provide effective and convenient communication methods, promote interactive teaching, improve teaching effectiveness, improve education fairness and transparency.

Scenario Overview

The streaming media solution based on cloud-region content Fusion is a cloud based data center, which constructs an application and platform-decoupled cloud service platform, which is used in combination with node VOD system, video direct seeding system and recording and broadcasting System.

The solution is to use the most advanced video "cloud Computing" technology, by adding a new layer of network architecture to the existing Internet, the streaming media content will be uploaded to the Center node service, and the "edge" nodes can be shared, so that users could get the content in multiple nodes and improve the utilization rate of video resources. To achieve the original construction of the independent streaming media system to achieve interoperability, to solve the duplication of resources, to achieve cloud users on-demand access.

The program, very good is the use of existing hardware and software, in the audio-visual library (or BoE) to increase a cloud of video storage and sharing, so that can integrate the education resources of the schools in a region and apply to streaming media video services, it can not only achieve a region or school resources sharing, but also to ensure that the policy of the unified export, Greatly improve the efficiency and resolve the use of limited resources.

Programme objectives

The establishment of public service video basic platform is the key component of the development of a new educational informatization system, which is to build a "unified, convenient, efficient and safe" educational digital platform. Viewgood Area Video Education Cloud's overall construction goal is:

1. Establish a unified, integrated, interactive provincial or municipal education basic video file database, integrated education video data and information (cloud computing Basic video database).

2. Integrate the resources and business processes of the existing Education Bureau (cloud computing video resource management platform).

3. Establishing or perfecting the basic portal of Education public service platform, realizing the single sign-on of educational service application, realizing the unified access of all educational applications (cloud computing application portal).

4. Construction of educational video resources operation system and management platform (Cloud computing operation Platform).

5. The establishment of education service system for schools, teachers, parents, students and natural persons to achieve role-based self-service (Cloud Computing Self-Service portal).

Programme architecture

The entire cloud video solution uses the distributed architecture deployment, the cloud service divides into the Web server, the database server, the direct seeding server and the streaming server, each school deploys the broadcast system (or the direct seeding system, on-demand system) The classroom configures the streaming media function component, In this way, real time can be transferred to the streaming media platform Management center of the global live server, while the recorded school color courseware can also be uploaded to the Jinshan Education Bureau Information Center of the streaming storage server, convenient for future retrieval, on demand, evaluation and other applications.

Program Application

1, remote classroom: On the Internet (Education Network) through the system online real-time viewing distance education channel, easy to realize remote lectures (same screen multiple screen live: All the way student video, all the way teacher video, teacher computer screen), online learning (review after Class), but also to solve some problems that can not come to school classes. At the same time, the signal to the Board of Education platform for other school students, at home, library, electricity or other places, real-time learning, can also watch the classroom after class video, complete the learning task. The real realization of the regional school resources, the balance of the teacher resources.

2, student training TV station: can let each school set up a number of internship television stations, so that the student community to host live television programs, can be announced scheduled activities in advance, then let the teachers and students live to watch, participate in various community activities, the process can be recorded in real time video files, and after the event to edit All channels not only published on the school's website, but also pushed to the Education Commission resources Integration network to facilitate the other schools to watch and study together. Multi-school activities to achieve collaboration, so that diversified activities, enrich and expand the students ' knowledge.

3, television broadcast: through the platform of the television simulation signal real-time collection and live out, so you can set up their own network education television stations, such as the central 10 sets, educational television stations. The educational Management department can determine the selected channel according to its own teaching plan and then collect it on the platform, of course, it can adjust regularly. Watching can be based on their own learning needs to choose to watch. It is easy to build the platform's TV channels into a large network of hundreds of channels. The use of cloud computing, the Central Board of Education can be the school's live signal fusion, and integration and then transmitted to the school without live signal collection, the rational use of resources to reduce the school's duplication of investment, the realization of the balance of educational resources.

4, Red Education: the classic, educational and learning value of films, educational films, feature films, documentaries and other concentrated storage to the video server, to facilitate the teacher-student after class Click Learning, enrich the students ' after-school life, so that students can develop all-round. The platform utilizes cloud computing technology to support all streaming media formats, which can be added in batches, and can only be identified by functions that greatly facilitate managers and viewers. The resources of the schools can be automatically integrated into the Education Commission, and can be examined please the resources of the BoE to the school's video educational platform to achieve resource sharing.

Program Overview

Cloud computing uses virtualization technology, it greatly saves the construction cost of IT infrastructure in the data center of BoE, supports the ability of carrying out multiple school (unit) business operations on the same set of IT infrastructures, helps the load and operation of various educational services in the data center, and utilizes the centralized processing advantage of cloud computing. Improve the operational efficiency of IT infrastructure and reduce the energy consumption of the entire education system.

In the next Generation education network, deploying video cloud computing will be an inevitable trend the cost of it technology is greatly reduced, whether it is the BoE (or the audio-Visual Studio) or the final school users, no longer need to pay much attention to the specific details of the various it technologies to achieve, but focus on their business logic and operating mode. Cloud computing allows every independent school platform to integrate resources and make practical plans for the integration of educational resources within the region.
