Government and public facilities
Media production and publishing Media production-Media producers can use their media production tools to make some audio and video streaming media according to actual needs, and they can also import media files from outside, which greatly expands the compatibility of publishable media.
Media release-The release process of streaming media is completely automated, and the producer does not need to care about the configuration of the streaming server, the actual address and related information, only need to have the user name and password for release, and configure the relevant parameters to realize automatic release. At the same time, the release of the media is quasi-synchronized on demand. When the media is uploaded to the server and the review is passed, the newly produced media can be viewed and ordered by the user. All media must be reviewed and qualified before they can be used by the user. Realized the quasi-synchronization of publishing and on-demand.
Media Information Editing-When media producers are making media, they can edit media information, including information such as movie posters, movie titles, directors, main actors, production companies, movie types, production locations, movie objects, etc., and Publish to the server along with the media files.
Tightly integrated with video-on-demand-the media publishing process is completely automated. In the media publishing process, the media can only be ordered by the user if it passes the audit of the media administrator. The connection between publishing and on-demand is fully automated. The tight integration with the video-on-demand system allows media managers to focus on media content review and other aspects.
Media management The media management platform is responsible for managing media files in the entire system. After the producer uploads the media file to the server, the media administrator further processes the media through the management platform, including modification, release, stop release, and deletion. Since all media use the exact same workflow, their management platform is also unified. Provide a unified management platform for different types of servers and the same type of servers in different locations.
Media censorship-media files that have been created are not immediately available to users (unless such a strategy is set). The system defines the media files produced by their subordinate production personnel by administrators of different levels, reviews these media files, and decides whether to publish the media files. Only media files that have passed the review have the right to be viewed on demand.
Media Search-Administrators can find media data according to their own requirements and modify the data. There are two ways to search for media, simple search and complex search. The administrator can process the search results.
Media maintenance-The production personnel complete the initialization of media information in the early stage of production, and the administrator can still manage and maintain this type of data. The types of media maintenance are: media subject maintenance, media origin maintenance, media player group maintenance, etc.
Account Maintenance-The media administrator can add, modify, and delete the account category of the media, and can browse all movie account lists.
Origin Maintenance-Media administrators can add and delete media origin content, and can count the number of movies in each origin.
Add media-Media managers can upload media without uploading through media production tools, but can add new media files directly through the WEB page, and can directly edit the basic information of the movie in WEB mode, including movie posters, movie names, Director, main actors, production company, film type, production location, film object, etc.
On-demand statistics-the system can count the number of on-demand times of all media files. Statistics can be based on the set statistical date, statistical time period, date and month and other parameters, and provide a histogram for easy analysis.
Live broadcast management Through the video capture card installed in the compression workstation, the system can capture the cable TV network, satellite reception signal, and even any video signal into digital signals in real time, and convert them into real-time digital signal streams, which are transmitted to the streaming media playback server. .
In the manual live broadcast process, the operator can enter the corresponding information of the live broadcast: live broadcast title, participant list, location, start time, estimated end time, cost, background information, etc.
In the automatic live broadcast process, each live broadcast workstation automatically checks its own device number after it is started. The device number is issued by the server and is used to uniquely correspond to the workstation. The creation of the device number is done by the server administrator. The administrator can explain the device corresponding to the device number in detail. For example, the device is a 19:00 news hookup broadcasted by the central station, or the device is a dedicated relay device for a conference site. After the live broadcast station is started, if the device has obtained the device number, it sends a device verification request to the server. Since the device number is related to the physical address of the local network card, if the device changes, you need to re-number authentication. If there is no device number locally, an empty device number is requested on the server to correspond to the local device. A live broadcast station can also have several device numbers at the same time, and the corresponding device needs to be specified when starting. The live broadcast station will automatically publish to users based on this device number.
Users use ordinary multimedia PCs, and after installing the client playback software, they can watch live TV programs through the Internet (IP network).
Live browsing-users can browse to the list of all current live programs and the schedule of upcoming live programs. By direct browsing, users can choose their favorite live programs to watch, and can also learn the basic information of each live program (such as Live broadcast name, broadcast venue, attendance, start time, end time, etc.).
Play management-live broadcast data is generated by the live broadcast terminal. After sending a live broadcast request to the server, the live broadcast terminal sends the live broadcast data stream to the server if it obtains permission from the server. At the same time, the server publishes the live broadcast information on the Internet, and the logged-in user can directly see the connection of the current live broadcast program. This process is completed by the server in the background and does not require administrator intervention. However, the administrator can stop the live broadcast of a certain channel at any time.
Timetable production-The administrator sets the schedule of the live broadcast according to the specific needs of the live broadcast terminal for query start and user viewing. The main information of the live schedule is: live broadcast name, broadcast venue, attendees, equipment Number, live broadcast object, cost situation, start date, start time, end date, end time, etc.
Device management-All types of devices currently in the system can be managed in a unified manner, and live broadcast devices can be added, edited, and deleted, and the current device usage status can be learned.
The system management system supports multiple servers and multiple media formats. System administrators can formulate other levels of administrators.
System monitoring-The system can dynamically monitor the server's operating status, such as the number of connections, CPU and memory usage, current media viewing status, media on-demand history records, and other parameters and information, and can count various parameter indicators.
Server management-System administrators can browse various servers, view various parameters of the server, and set the server. You can set the server's virtual directory, set the server's database pointing, user authentication methods and other parameters.
System log management-system administrators can view all log files of the video-on-demand system, and can choose to receive according to the time
