High-standard definition compatibility and high-safety news non-linear editing network system

Abstract

The invention relates to a high-standard definition compatibility and high-safety news non-linear editing network system, which is characterized by comprising a workstation part, a network security and exchange part, a central storage part and a server part, wherein the workstation part can be used for realizing a function of editing locally and then editing the network and is used for producing news programs, and all workstations are used for storing medium-code stream materials; the network security and exchange part is used for connecting all workstations in the system to ensure the exchange between a media file and a data file; concentrated storage is realized on the central storage part by using a disk array of a single central storage body; the central storage part is used for storing high-code stream materials; and the server part is used for realizing a news program network producing function. According to the high-standard definition compatibility and high-safety news non-linear editing network system, by taking central storage as the main and local storage as the backup, a synchronous mirror image is stored in the central storage part and the local storage by media resources when local editing is performed; the media resources of the local storage are used for editing, browsing and synthetizing the backup, and the media resources of the central storage part are used for output synthesis, therefore, high-standard definition seamless compatibility, ultrahigh safety, double-code stream editing, media backup of material push, asymmetric double reading and writing, offline editing and offline broadcasting are realized, and high-definition production is realized at the production cost of a standard-definition network. The super cost performance is high.

Description

Technical field [0001] The present invention involves a non -linear editing network (ie, non -editing network) system for TV programs, and especially involves a high -standard clear and high -security news non -editing network system.Non -editing networks are widely used in radio and television, education and other industries.The present invention proposes a new news non -editing network system solution based on increasing network security and reducing network bandwidth and applicable to the high -definition system. Background technique [0002] With the continuous development of IT technology, the writing, submission, nuclear review, news film production, and broadcasting of traditional news can be completed through the Internet. This method has greatly improved the efficiency of news production.However, the previous distributed storage non -editing network technology can only be applied to a smaller non -editing system, because the material of the non -editing system is not man...

AI Technical Summary

Problems solved by technology

However, the previous distributed storage NLE network technology can only be applied to building a small-scale NLE system, because the materials of the NLE system are not managed through the database. If the network scale is large and there are many workstations, the search and use of materials It is very inconvenient, and the security is also lacking. If the hard disk storage of the priority workstation cannot be restored, although the emergency production mode can be adopted, the project files and materials produced before will no longer exist. The program does not effectively guarantee

However, the security of today's centralized storage NLE network hardware architecture cannot be guaranteed. Although the network has the guarantee of active and standby servers and active and standby central storage, if the database, switch and other network paralysis problems occur, it will directly affect the news. Production and broadcasting, there have been cases that have seriously affected news broadcasting, and the network uses the materials of the central storage in real time during news production, which has high requirements for network bandwidth. If many workstations are used at the same time, the program production There will be stuttering and stuttering, especially in the high-definition state, it is impossible to imagine how to make
