On-site comment and hand-drawing method based on television subtitling system

Abstract

The invention relates to a comprehensive application of a television caption technology and a picture hand-drawing technology in the radio and television field, in particular to an on-site evaluation and hand-drawing method based on a television caption system. The method comprises the following steps: the data is collected through a client-side commenting and hand-drawing system, the hand-drawing data is packaged and is transmitted to a server end through a Socket protocol in real time, the server end receives and analyzes the data to generate a caption signal, and the caption signal is transmitted to the switching table and then is broadcast after being mixed with the scene picture. The invention has the advantages that the hardware purchasing cost of a user is not greatly increased, the digital image processing device with high price is not required to be provided, the input cost of the user is reduced, and the application flexibility of the user is extended.

Description

technical field [0001] The invention belongs to the comprehensive application of TV subtitle technology and graphic hand-drawing technology in the field of radio and television, and in particular relates to an on-site commentary and hand-drawing method based on the TV subtitle system. Background technique [0002] In the radio and television industry and related fields, TV subtitles have always played a pivotal role. TV subtitles can intuitively show the audience and enrich the content of the picture to achieve the role of interaction with the audience. Especially with modern TV technology, the audience is more concerned about the packaging quality of the program. The higher and higher, the TV subtitles are developing towards the network direction of more beautiful, more real-time information and more professional content. How to make traditional subtitles bring brand-new visual impact and viewing effect to the program? This problem is particularly prominent in programs such...

Problems solved by technology

[0004] At present, these two commonly used solutions have their limitations. The cost of hardware is too high for users in solution 1, and users must purchase brand new hardware systems to meet their needs.

Moreover, the flexibility and reusability of this solution are too poor, and it does not have network functions, so it cannot meet the needs of sports commentary systems such as on-site comments and background broadcasts.

Option 2 will have a certain hardware cost, but compared with the first option, the hardware cost has decreased, but the software development and maintenance costs will increase, and the user must purchase two sets of equipment to achieve the purpose, one system is used for hand-painting The generation of graphics, another system is responsible for the output of the image

And it does not have the flexibility of network manipulation and live broadcast
