Video frequency source material synthesizing method

Abstract

The invention relates to a video material synthesis method, which belongs to the technical field of radio and television broadcast control systems. In the prior art, the TV station uses a video recorder to realize the synthesis of multiple video materials. When synthesizing the materials, it is necessary to locate the in-point and the out-point of the synthesized material first, and then preview and generate the combined material. However, the video recorder is a linear playback device. It is troublesome to point and point out, and time-consuming to synthesize; it is also very difficult to modify; it is easy to damage the tape. Although the video server is easy to locate the material, it has no material synthesis function. The method of the present invention uses the control characteristics of the video server to record the in-point and out-point of material positioning and map it into a logical mapping table to achieve the effect of logical synthesis; if modification is required, only the in-point of the logical mapping table needs to be modified and point information. By adopting the method of the invention, the material synthesis efficiency is greatly improved, the modification is convenient, and the video content and sound are not damaged; additional storage media and equipment are not required.

Description

technical field [0001] The invention belongs to the technical field of radio and television broadcast control systems, and in particular relates to a method for synthesizing video materials. Background technique [0002] In the radio and television system, the various TV programs that the audience sees are the effects of processing and synthesizing various materials. Obviously, the production of materials is the premise of broadcasting, and it is also a very important link. In the process of material production, a lot of work is the synthesis of materials, that is, the different contents of multiple different materials are synthesized into one material for broadcasting. In the prior art, TV stations usually use video recorders to realize the synthesis of multiple materials. When performing material synthesis, the staff first locates the in-point and out-point of the material to be synthesized, and previews the effect of the synthesized material. If there is no problem with t...

Problems solved by technology

However, since the video recorder is a linear playback device, it is troublesome to locate the in-point and out-point of the material, and the synthesis is time-consuming; if other personnel review the synthesized material and find that it is unqualified, they need to re-compose the material, which is inefficient; at the same time, Multiple playbacks of the tape can also easily damage the tape

However, in the broadcast television system, the video server is a non-linear playback device. It is easy to locate the material, has high playback control efficiency, and has no damage to the material video content and sound. However, it has no material synthesis function and cannot be previewed before it is actually generated.

In addition, when the materials are located on different video servers, how to quickly synthesize is a difficult problem
