Problems solved by technology

Disadvantages of displaying one-dimensional barcodes and two-dimensional codes on the screen: Since one-dimensional barcodes and two-dimensional codes are static display methods, there is a certain limit on the number of characters, one-dimensional barcodes cannot display Chinese characters, and one-dimensional barcodes are enlarged. The length is not compatible with the existing recognition equipment hardware and is not compatible with the existing specification requirements; if the amount of information of the two-dimensional code is increased, the area of ​​the two-dimensional code image on the display screen will be further increased, the recognition time will be slowed down and the image content will be affected. The above method requires the first Third-party software support is not compatible with existing word processing software
For example: 1. It is impossible to use the camera on the mobile phone and tablet computer to digitally scan and record conventional subtitles in the text records of video conferences and remote TV teaching, and the existing analog recognition methods have large errors and slow speeds
2. There is a contradiction between looking at images and reading text (especially during the demonstration and experiment process in the teaching process)
[0003] Currently, one-dimensional barcodes and two-dimensional codes used in the Internet of Things and other fields can only display static information, have strict restrictions on the number of characters, and require third-party software , QR code recognition is slow, software and hardware environment are required in the application, and it has nothing to do with existing word processing
Therefore, the above method is not suitable for displaying and recording dynamic large-capacity text information.

Embodiment 1

[0027] A method for editing and displaying dynamic synchronous character information barcodes in a TV system. In the video editing at the output end of the TV system, any conventional character string is inserted into a single-character window through character insertion technology, and converted into a machine through the font conversion function in word processing software. Character reading code strings, display dynamic machine character reading code strings on the TV display screen at the receiving end of the TV system or in the single-character window of the computer monitor; use the cameras on mobile devices such as smartphones and tablet computers or communicate with The machine character reading code connected to the smart phone and the tablet computer obtains the machine character reading code string and converts the read machine character reading code into a regular text string through the character conversion function of the word processing software of the above-menti...

Embodiment 2

[0029] According to the editing and display method of the dynamic synchronous character information barcode described in embodiment 1 in the TV system, the method for displaying the dynamic machine character reading code string in the described single character window, when the video system character is edited (real-time or non-real-time) Input a character string (ASCII code or GB2312 code) in a conventional way, and convert it into a machine character reading code through the existing font conversion function. Insert a single-character window, that is, a 12*8 dot matrix display window that moves left and right in the machine character reading code (such as Image 6 shown); the machine character reading code moves up and down the 8*12 dot matrix display window (such as Figure 7 shown); the 24*8 dot matrix display window that the machine character reading code moves left and right (such as Figure 8 shown); the machine character reading code moves up and down the 8*24 dot mat...

Embodiment 3

[0031] According to the described dynamic synchronous character information bar code of embodiment 1 or 2 in the edit and display method of TV system, described single character window and font conversion method, single character window is divided into the machine character reading code horizontal movement of ASCII code format 12*8 dot matrix window, ASCII code format vertical movement 8*12 dot matrix window, GB2312 code format horizontal movement 24*8 dot matrix window, and GB2312 code format vertical movement 8*24 dot matrix window. Set 2 horizontal marking lines on the top and bottom of the horizontal movement mode window and set 2 vertical marking lines on the left and right of the vertical movement mode window as camera identification marks. Above-mentioned mark line is fixed mode and does not move with machine character reading code movement. Input characters or insert the whole article in a conventional way in video system editing, convert the font into a machine charac...

Abstract

A method for editing and displaying dynamic synchronous character information barcodes in a television system. One-dimensional and two-dimensional codes have problems such as displaying only static information and strict restrictions on the number of characters. The method of the present invention comprises: in the video editing of the TV system output end, inserts any conventional character string in the single character window by the character insertion technology, converts into the machine character reading code string by the font conversion function in the word processing software, and reads the code string at the receiving end of the TV system The dynamic machine character reading code string is displayed in the single-character window of the TV display or computer monitor; use the camera on mobile devices such as smartphones and tablet computers, or machine character reading connected to smartphones and tablet computers through USB interfaces or Bluetooth wireless methods Code to obtain the machine character reading code string and convert the read machine character reading code into a regular text string through the character conversion function of the word processing software of the above-mentioned equipment. The invention is used for editing and displaying the barcode of dynamic synchronous character information.

Description

Technical field: [0001] The invention relates to a method for editing and displaying a barcode of dynamic synchronous character information in a television system. Background technique: [0002] At present, one-dimensional barcodes and two-dimensional codes have been more and more widely used in digital TV systems. Combining with smart phones and tablets to read two-dimensional codes on the screen can expand TV information and greatly increase the additional value of TV programs. amount of information. Disadvantages of displaying one-dimensional barcodes and two-dimensional codes on the screen: Since one-dimensional barcodes and two-dimensional codes are static display methods, there is a certain limit on the number of characters, one-dimensional barcodes cannot display Chinese characters, and one-dimensional barcodes are enlarged. The length is not compatible with the existing recognition equipment hardware and is not compatible with the existing specification requirements...
