2A, A is a line synchronization signal, B is a color burst, C is a bit synchronization, and D is a data line.

In FIG. 2B, E denotes byte synchronization, and F denotes a data unit. In FIG. 2C, G denotes a prefix, H denotes a data block, J denotes a data packet, and K denotes a suffix signal .

In addition, such a character broadcasting system is used by most advanced communication countries such as West Germany, Japan, the United States, France, the United Kingdom, and Korea in the world. These countries use the scanning lines and frequencies (for example, 625/50, 525/60, And the like are used in some types of different character broadcasting systems.

On the other hand, Korean text broadcasting is designed to insert various kinds of information using the CABIS signal data inserted into the back porch side of the horizontal sync section of the video signal.

For example, the frame rate signal is a signal form that is multiplexed and allocated to a horizontal scanning line signal of a video signal as information of a program provided on the side of a broadcasting station formed as shown in FIG. 3. Here, Block, and data block, and one word is formed in 8-bit (1-byte) units.

In addition, the above-mentioned CABI PS stipulates a measure to cope with various matters that may occur in program transmission such as precedence, delay, cancellation and change of program broadcasting with reference to a program table broadcasted on the television receiver screen, It is possible to perform the scheduled recording of only the actual broadcast portion of the broadcast program (the portion other than the broadcast portion of the broadcast, the middle portion, and the rear portion of the broadcast portion) is correctly and quickly input.

This program displays the program for one week (or four weeks) on the TV screen according to the preset recording method, moves the desired program by using the cursor when the user wants to record the desired program, So that it is possible to accurately record a program even if there is a change in program start time due to a broadcast station or the like.

The transmission data at this time is as follows.
