Description

TECHNICAL FIELD The present invention relates to a video production cloud service system, a cloud service method for its video production,

The present invention relates to a method and apparatus for efficiently and rapidly producing images used in media fields such as broadcasting, internet, news, movies, and publishing, , Transcoding, and the like, are provided as cloud services by accessing the Internet, thereby enabling the production staff to perform common video production operations.

Today, the media production environment has largely changed from analog editing using VCRs to file-based digital editing using NLE editors. Therefore, the number of cases of network-based image production system (below) is increasing, and there is a growing demand to integrate NPS that is independently constructed.

When an incident of injustice occurs in our daily life, before the coverage team such as broadcasters and media companies arrive at the scene, the moment of thinking will be recorded by mobile devices such as smart phones and tablet PCs, which are already carried by many citizen journalists These images will be delivered through the social network of the Internet. The network transmission using a mobile device, that is, it shows the era of the digital media we are living now.

The news that the Gangnam Station crossroad was flooded in 2011 was delivered first with the video via SNS, not the media. The car drifts in a mountainous landslide at Wumyeong Mountain in Bangbae-dong. And the vivid images of muddy water running toward the apartment are images recorded by mobile devices carried by citizen journalists. This is a collaborative effort between file-based mobile video recording devices, not tape-based, and networks capable of transmitting them.

In addition, it wants to produce final images faster and more efficiently than broadcast media, communication, news, movies, and publishing, and distribute them to various places at the same time.

Therefore, the network-based production system (NPS) is a system that provides an effective production environment for editing a plurality of image sources into a nonlinear editor (NLE) and adding various effects to complete the final service image. Control the work flow between workers or centrally manage the collected and edited content to improve work productivity and minimize loss or corruption of data due to operator error.

However, the image production environment changed to file-based digital editing using NLE, but most of the producers still maintain the work environment and workflow of the traditional 1: 1 editor only when the image is changed from analog to digital . In order to make full use of the current status of the video storage unit changed from video tape to file, remote editing of networked files and supporting various collaborative productions are actively supported, resulting in delays and inaccuracies due to time and place In order to minimize the errors of the video output resulting from a communication, it is becoming more important to utilize the Internet to get out of the limited production environment.

It is very difficult for individuals and producers who produce many common images to construct such a network-based production environment in terms of cost and operational management of the system. Therefore, a cloud-based service is needed that enables producers, including individuals, to maximize production efficiency at low cost.

Now, the transition to the file-based production system in the field of broadcasting and film, which deals with high-quality video, has become full-scale. This is an intermediate-level digital production system (HD-SDI) that broadcasts the video received through HD-SDI (a method of converting a digital video signal to a serial signal and converting it to a coaxial cable without compressing the digital video signal) But also in the form of digital files, from the production to the transmission.

However, most producers, except for large broadcasting companies, are small enough to build or introduce such network-based NLE systems themselves, and although they recognize the necessity of the NLE system, the introduction of NLE systems is costly. Hence, if we can leverage the same network-based manufacturing system (NPS) capabilities at a low cost by combining cloud systems, more producers and individual producers will be able to take advantage of the efficient production environment. However, as the use of the nonlinear editing system (NLE), which is supplied at a relatively low cost, becomes common in general manufacturers, the demand for the digitalized image production environment is gradually increasing.

In the present invention, as a high-quality image is generalized, a general image production work includes shooting, acquisition, editing, compositing, post-work, and distribution. However, since such an entire process requires a huge initial cost when a digitalized image production environment is implemented by a centralized server, most of the manufacturers other than large-scale broadcasters or large corporations with capital are unable to build and operate such a system, To provide a powerful video production environment based on cloud service.

Another object of the present invention is to provide a method for enhancing compatibility of digital video contents, greatly improving productivity of contents, and obtaining high quality video results by providing service of transcoding and transmission functions of all various image contents to the cloud.

The present invention includes a content management module for managing video / user / authority / workflow, including an ingest module for acquiring and registering images, an NLE editor, a transcoder for transforming images into a required digital format, A nonlinear editor (NLE) interlocking plug-in module, a streaming and transmission distribution module for video, and a storage management module for large capacity. These modules include the modules needed for the cloud service.

And a cloud storage management system that stores and manages the images in a cloud so that the images can be efficiently recycled at any time by allowing the images to be gradually increased in capacity through the existing Internet,

The module for this purpose is a meta data management module that can be configured efficiently to flexibly reflect production management characteristics of various users, a content based and ontology search module for efficiently searching all related images registered in the cloud, A low resolution proxy view module for viewing and viewing registered images anytime and anywhere, an on-line editing module for enabling on-line editing only by an Internet browser, and a cloud storage device for flexible adjustment of storage capacity.

Especially, it includes a systematic centralized system for work flow and control functions for efficient and fast work environment and includes a transmission distribution module that efficiently responds to image content publishing service (broadcasting, IPTV, social network service, social game, blog) do.

According to the present invention, the present video media market has been actively developed for the production of large-scale movies (avatar, Harry Potter, Yi, and Interstellar) and HD / UHD, Demand is expected to increase. Therefore, by using cloud-based production system, the storage / security / sharing of digital content is optimized, and the final result can be easily, quickly, and easily accessed without discrimination between format conversion and audio / CG / Can be made. In addition, due to the efficient operation environment by network access, it is possible to improve the competitiveness improvement effect by shortening the production time and improving the quality of the product by increasing the use efficiency of One Source Multi Use. In other words, it is possible to increase production productivity by decreasing communication errors of production comments due to the unification of the manufacturing staff of many personnel or the manufacturing system between the raw and subcontracting subcontractors, and the production cost can be remarkably reduced And it is expected to have many effects such as expanding the manpower in the media content market.

2D, FX / Composite, 3D Modeling, Visual Effect, and Rendering work, which make up the workflow of image production work, are switched to Tape-to-Storage method instead of Tape-to-Tape moving method. It reduces the cost of building the production infrastructure and controls the video workflow at various stages. This saves production time and reduces redundant investment through systematic management of the produced video sources.
