Background overview
With the development of information technology, the amount of information that needs to be stored and disseminated is increasing, and the types and forms of information are becoming more and more abundant. The mechanism of traditional libraries obviously cannot meet these needs. Therefore, the digital library came into being. The digital library is a storage of electronic information. It can store a large amount of information in various forms. Users can easily access it through the network to obtain this information, and its information storage and user access are not restricted by geography. The school establishes a modern digital multimedia library. In addition to including some e-books, teaching materials, and library files in this multimedia library, you can also upload some materials in the teaching CD to the platform, which can make the use of resources Maximize while meeting the learning needs of multiple people. Teachers and students can browse at will as long as they enter the relevant web pages, which will save the trouble of borrowing CD materials. At the same time, some precious video and video teaching materials can also be stored and used for a long time. The VIEWGOOD digital library multimedia video solution is developed for this function, using streaming video-on-demand technology to achieve network communication. This is an emerging network technology with convenient storage and transmission of resources and low cost. With the help of the school network (or the Internet), readers can browse multimedia resources freely, without being restricted by time, space and region. The retrieval efficiency is high and the transmission speed is fast, which is the mainstream way in the future.
demand analysis
1) Small information storage space is not easy to damage;
Digital libraries store information in digitized form, generally stored in computer compact discs or hard disks, and occupy a small area compared to paper materials in the past. Moreover, a major problem in library management in the past is that the materials will wear out after being checked many times. Some original and precious materials are difficult for the general readers to see. The digital library avoids this problem.
2) Convenient information retrieval and retrieval;
Digital libraries are equipped with a computer search system. Readers can obtain a large amount of relevant information by retrieving some keywords. In the past, the search of books and materials had to go through many procedures such as searching, looking for libraries, and searching for books by search number, which was cumbersome and inconvenient.
3) Quickly transmit information remotely;
The construction of the library is limited. The location of traditional libraries is fixed, and readers often spend a lot of time on the way to the library. Digital libraries can use the Internet to quickly transfer information. Readers can log in to the website and click the mouse. Even if they are thousands of miles away from the location of the library, they can see the information they want to consult within a few seconds. This is convenient. It is unmatched by libraries in the past.
4) The same information can be used by multiple people at the same time;
As we all know, a book can only be lent to one person at a time. In a digital library, this limitation can be broken, and a "book" can be lent to multiple people for viewing through the server at the same time, which greatly improves the efficiency of information use.
Design
1) System core module: The system adopts centralized deployment, which can manage all servers in the central computer room. It is convenient to manage and does not need to consume too much manpower and material resources; supports a variety of media formats, in addition to common MPEG1, MPEG4, REAL and other streaming media formats In addition, it also supports all non-streaming media, enabling unified management and unified scheduling of resources; using dynamic ID generation verification technology, double authentication (user authentication, end-to-end dynamic ID authentication), effectively preventing users from using various tools Program download and watch theft chain; perfect anti-theft chain mechanism to avoid the operator's resource loss in a timely manner; with telecom operator-level stability and security, can easily cope with 7 × 24 hours of safe and stable operation.
2) Resource management module: for the frequent addition of program video content, the system provides a powerful batch addition function, which can either manually select multiple files for addition operations, or select a directory (which can contain multiple subdirectories) for batch addition Operation, you can add content introduction, content thumbnail, etc.
3) Live broadcast module: the use of KeyBuffer technology with independent intellectual property rights of VIEWGODO makes the live broadcast delay extremely short, and fully guarantees the live broadcast live effect; supports the collection of multiple live broadcast signal sources, realizes mobile, live, and screen capture stereo, and the combination of collection methods is more Free and flexible; the mode of live broadcast and recording separation, you can choose to record or not record conference video according to your needs, and you can add the recorded video to the on-demand library for on-demand use.
4) User experience module: optimized design for user needs, beautiful interface, easy operation, and more prominent user communication function; VIEWGOOD service core using NoDelay technology cooperates with a dedicated player to bring a perfect experience of playback effect, Support drag and drop of any streaming media format, drag delay is extremely short;
5) Function enhancement module: can publish video with integrated video, text, and pictures, making the video colorful and no longer boring on the tablet;
6) Training and assessment function: It can enable students to conduct targeted assessment while on-demand resources to further improve their ideological awareness and learning ability.
