[0010]

FIG. 1 is a block diagram showing one embodiment of a text data display device in a receiver according to the present invention. In FIG. 1, a receiver 1 includes a microcomputer 2 for controlling the entire operation, a tuning circuit 3, and an RD
S demodulation circuit 4, selector circuit 5, OSD IC 6
And an FL display tube 7. Microcomputer 1
Has a memory 2a, and the RDS demodulated by the RDS demodulation circuit 4
Radio text data (hereinafter referred to as RT data) included in DS (radio data system) data is stored.

The tuning circuit 3 is connected to an antenna 8, the microcomputer 1 is connected to an external source device, for example, a CD text compatible CD player 9 via a serial bus, and the OSD IC 6 is connected to a monitor TV 10. The CD text data from the CD player 9 is displayed on the FL display tube 7 which is a built-in display device via the serial bus and the microcomputer 2, and further displayed on the screen of the monitor TV 9 via the OSD IC6. be able to. Since the memory 2a of the microcomputer 2 always stores the RT information, even when the CD text data from the CD player 9 is displayed on the screen of the FL display tube 7 and the monitor TV 10, the RT data is stored in the RD.
When the data is input from the S demodulation circuit 4, a process of capturing RT data is performed. Thus, when the display mode is switched from the CD text mode to the RT mode, it is possible to immediately display the latest RT data.

TEXT A, TEXT as RT data
If both B exist, the following processing is further performed. (For example, in RDS, TYPE 2A is text data of 64 characters and TYPE 2B is text data of 32 characters. Here, as an example, the case of TYPE 2A will be described.) (1) Normally, TEXT A, TEXT are used for RT data When both B exist, the first character of TEXT A to TE
64th character of XT A → 1st character of TEXT B to TEX
The scroll display is performed on the screen of the FL display tube 7 and the monitor TV 10 in the order of the 64th character of TB →. (2) When the scroll display is being performed, the CD
The CD track number being reproduced by the player 9 changes, and a new CD corresponding to the new CD track number is changed.
When the text data is sent to the microcomputer 2 via the serial bus, the display of the RT data on the FL display tube 7 and the monitor TV 10 is temporarily stopped, and the display of the CD text is performed for a predetermined time (for example, 5 seconds). Do it.

(3) When a predetermined time (for example, 5 seconds) elapses after displaying the CD text data, the screens of the FL display tube 7 and the monitor TV 10 return to the RT data display. At this time,
To determine which character of which text to resume display,
It is determined by the character position when T data display is interrupted. There are the following ways to restart the display. (3a) The display is restarted from the place where it was interrupted. (3b) Resume from the first character of the interruption data at the time of interruption. (3c) For example, when interrupted, 4
When the character after the 0th character is displayed, the display is restarted from the first character of the other text. (3d) If it is earlier than 40 characters, the display is restarted from the first character of the text. (3e) When there is only one of the text data A and B, the display is always restarted from the first character.

FIG. 2 is a flowchart for explaining an example of the above operation. First, in step S1, the microcomputer 2 determines whether or not the display mode is the CD text data display mode. If yes, the process proceeds to S2; if no, the process proceeds to S11. In S2, it is determined whether or not the CD text data display timer in the microcomputer 2 has timed out for a predetermined time (for example, 5 seconds). If no, the process proceeds to S3, where the display of the CD text data is continued, and Return.
If the answer to S2 is yes, proceed to S4 and change the display mode to RT.
Switch to data display mode. Next, in S5, the microcomputer 2 determines whether or not the RT data before the CD text data display is TEXT A. If YES, the process proceeds to S6, and if NO, the process proceeds to S9.

In S6, when the mode is switched to the CD text display mode, the microcomputer 2 determines whether or not up to the 40th character of TEXT A has been displayed.
If no, the process proceeds to S8. In S7, TEXT
The microcomputer 2 determines whether or not there is data of B. If yes, proceed to S8, and if no, proceed to S10. In S8, an instruction is given to start display from the first character of TEXT B, and then the process proceeds to S14, where the RT data is displayed on the screen of the monitor TV9. On the other hand, if the answer to S5 is no, the microcomputer 2 determines whether or not up to the 40th character of TEXT B has been displayed when switching to the CD text display mode, and proceeds to S10 if yes. If so, proceed to S8. In S10, an instruction is given to start display from the first character of TEXT A. Then, the process proceeds to S14, where the RT data is displayed on monitor T.
It is displayed on the screen of V9.

If the answer to S1 is no, the microcomputer 2 determines whether or not there is a change in the CD text data (that is, a change in the CD track number). If so, the process proceeds to S14, where the RT data is displayed on the screen of the FL display tube 7 and the monitor TV9. In S12, the display mode is switched to the CD text mode, then the CD text data display timer in the microcomputer 2 is started, and the process returns to S1.

As described above, the CD text data sequentially sent from the CD player 9 can be displayed on the FL display tube 7 of the receiver 1 or the OSD of the monitor TV 10 without any omission, and always after the end of the CD text data display. Since the display is restarted from the first character of the RT data, the user can easily understand the contents. Further, when the CD text data changes, the contents are displayed on the display unit of the receiver or the external monitor device in addition to the display unit of the CD player, so that it is easy to see.

[0018]

According to the present invention, a plurality of text data can be displayed, and there is an advantage that the user can easily see and understand.
