Problems solved by technology

This greatly wastes the time of file transmission, not only reduces the efficiency of program production, but also wastes a lot of network resources
For live broadcast programs with high real-time requirements, the studio requires rapid editing of the acquired program materials. After the files recorded by the recording system are edited non-linearly, they must be synthesized into materials through program synthesis and provided to the studio for broadcasting. Traditional programs The efficiency ratio of synthesis is about 1:1.5, that is to say, making a program requires one and a half times the length of the program for synthesis, which seriously affects the real-time performance of the broadcast.
At the same time, the existing method of program synthesis is to synthesize high-definition and standard-definition separately. For the current business model of mixed production of high-definition and standard-definition, high-definition program synthesis and standard-definition program synthesis need to be combined separately, which is a serious waste of resources.

Embodiment 1

[0024] This embodiment is a program synthesis system suitable for networked intelligent digital media, such as figure 1 shown. This embodiment includes: a disk array connected to each other through a network, a database server, a management server, a plurality of composite servers (shown as 4 in the figure, there may be more in practice), a splicing server, a database server, the disk array There are: storyboard database, material database, synthesis database, splicing record database, splicing completion database; described management server is provided with intelligent analysis engine, service unit, task monitoring unit, file management unit, described intelligent analysis The engine includes: a task type analysis device, a synthesis type analysis device, a task splitting device, and a storyboard structure intelligent analysis device; the synthesis server is provided with: a decoder, an overlay renderer, an encoder, and a file synthesis output device; The splicing server is...

Embodiment 2

[0030] This embodiment is a method for synthesizing digital media programs using the system described in Embodiment 1. Program synthesis refers to the combination of multiple video materials to form a complete TV program file. For example, putting multiple pictures in one picture for presentation, of course, this is just the simplest program synthesis.

[0031] Program synthesis first requires a storyboard file similar to a movie storyboard script. This storyboard file has a very clear description of the overall idea of ​​the TV program to be synthesized. The storyboard file comes from the non-linear editing system of TV programs and is a digitized file. The storyboard file contains various parameters such as the content and length of the TV program to be synthesized, as well as various parameters of the materials required for synthesizing the TV program, as well as how to combine these materials and the way of combining them. various parameters.

[0032] The method of synt...

Embodiment 3

[0074] This embodiment is an improvement of Embodiment 2, and it is a refinement of the task splitting steps in Embodiment 2. The splitting method described in the task splitting steps described in this embodiment is: fixed-time splitting, One of split or smart split based on the number of composite servers.

[0075] The implementation of intelligent splitting: after the intelligent analysis engine receives the synthesis task submitted by the non-editing editor, and the material validity test is passed, under the condition of distributed synthesis, the intelligent analysis engine conducts intelligent analysis on the structural characteristics of the project file, and the During non-editing and editing, scan and classify the applied special effect types, audio, video, and subtitle files, evaluate the complexity of their splitting, divide project files with similar complexity into a group, and Part of the file is split again to determine whether the minimum split unit is met. If...

Abstract

The invention relates to a program synthesis system and a method applicable to networked intelligent digital media. The system comprises a disk array, a management server, a plurality of synthesis servers and a spliced server that are mutually connected by a network, wherein the disk array is internally provided with a storyboard database, a material database, a synthesized database, a spliced record database and a spliced completion database, and the management server is internally provided with an intelligent analysis engine, a service unit, a task monitoring unit and a file management unit. The intelligent analysis engine of the system can be split according to the storyboard complexity, a certain storyboard length and the quantity of configured servers. As a task type analysis device is adopted, the high-definition distinguishing is conducted on a task, the high-definition intelligent switching is supported, the working form of each server is automatically switched according to a synthesis target, the synthesis quality is ensured, the equipment redundancy is achieved due to the synthesis servers, and the safety performance of the system is improved.

Description

technical field [0001] The invention relates to a program synthesis system and method suitable for networked intelligent digital media, which is a computer network application system and method, and a digital media content processing system and method. Background technique [0002] The traditional linear editing method requires a large number of video recorders for TV program production, but with the development of IT technology, the program production system has gradually developed from a tape-based linear editing system to a disk-based non-linear editing system. However, the non-linear editing system and the synthesized media files cannot realize the convenient sharing and collaborative work of materials. Therefore, the non-linear editing network system combined with network technology has developed rapidly, and the networked program production system has become a non-linear editing network system. It plays an important role in the efficiency of program production and the ...
