Distributed-storage non-linear editing network for television program design

Abstract

The invention discloses a distributed-storage non-linear editing network for television program design, which is characterized in that: a windows operating system is arranged on a dominant server, and active directory program of the window operating system provides user account management in the non-linear editing network and sets user account permissions and work paths; the windows operating system and third party editing software are arranged on non-linear editing workstations, storage space of each user account is divided, and read-write access limit, disk quota, and drive map of the storage space are managed by the dominant server and a special working disk is built for each user account; and when a user loges in a non-linear editing workstation, edited script operates automatically, and no matter which workstation the user loges in, the script maps the special working disk corresponding to the account of the user into the current working disk of the user after operation. By utilizing general PC hardware, the non-linear editing network realizes non-linear editing network architecture of raw data scatter storage, file network transmission, primary localization edition and secondary net edition through software setup and script operation on a general windows platform. In addition, the non-linear editing network has low network hardware equipment investment, convenient maintenance in use after establishment and high network safety performance.

Description

technical field [0001] The invention relates to a system architecture for a non-linear editing network (ie, non-linear editing network) used in television program production, in particular to a distributed storage non-linear editing network architecture. NLE networks are widely used in radio and television, education and other industries. The present invention proposes a major improvement on the very important storage service part of the NLE network, and adopts a distributed storage network architecture, which provides a safe And more cost-effective video non-linear editing network solutions. Background technique [0002] From the creation of TV to the present, the recording medium has also undergone great changes with the development of technology, from the initial analog tape, to digital tape, and then to today's optical disc, hard disk, and semiconductor card. The production methods have been promoted, especially the development of IT technology, which has continuously ...

Problems solved by technology

[0005] The first thing to bear is the security issue. The centralized storage of material is equivalent to "putting all eggs in one basket". If the material storage (pan tower) server or database server fails, the consequences will be disastrous. Therefore, in order to prevent single point of failure occur, a lot of backup measures need to be taken inside the network, which increases the construction cost of the network and increases the complexity of the network

[0006] In addition, the use of a large number of professional equipment and professional software also requires a large number of very professional network maintenance technicians, which increases the unit's personnel costs and greatly increases TCO (Total Cost of Ownership).

[0007] Furthermore, after the system is completed, due to the limitation of storage bandwidth, it is difficult to expand the site

[0008] There is also a simple distributed storage NLE network, that is, each person has a NLE workstation and each works independently, but the disadvantages are also obvious. First, the utilization rate of the equipment is not high, because the editor does not always use the NLE workstation. It is completely possible to achieve "time-division multiplexing" by multiple people; secondly, it is inconvenient to share and use materials, etc.
