Send. Thereby, the captain screen information is displayed on the display device 3 (S10).

Note that in step S6, if the information displayed on the display device 3 is identified as captain screen information, step S7. The process moves to the protocol interpretation operation of step S9 without going through the operation of S8.

Further, if the input signal is identified in step S2 as not being the captain screen information signal CP, and in step S3 as being the character information signal CR, the signal distribution unit 2
1 sends the character information part CRI of the character information signal CR to the character information interpreter 23 (S11).

In response to the input of the character information section CRI, the character information interpreter 23 identifies whether the information currently displayed on the display device 3 is character information or not (S12).

In this step S12, if it is determined that the display information is not text information, a full screen erase signal is sent to the display device 3 to erase display information such as captain screen information (
S13).

Next, the character information interpreter 23 interprets the character information in the input character information section CRI so that it is displayed in the character information display method defined by the terminal device (S14), and uses the interpretable signal of the display device 3. This converted signal is output to the display device 3. As a result, character information is displayed on the display device 3 (S15).

Note that if it is determined in step S12 that the information displayed on the display device 3 is text information, the process moves to the text information interpretation operation in step S14 without going through the operation in step 813.

Further, if the input signal is identified as not being the character information signal CR in step S3, and is identified as being the facsimile information signal FM in step S4, the signal distribution unit 21
is the facsimile information part F of the facsimile information signal FM.
Sends the MI to the facsimile information interpreter 24 (S1

If it is determined in step S17 that the display information is not facsimile information, a full screen erase signal is sent to the display device 3 to erase one display information such as captain screen information (518).

Next, the facsimile information interpreting section 24 interprets the facsimile information in the input facsimile information section FMI so that it is interpreted according to the facsimile information display method specified by the terminal device (S19), and displays the facsimile information on the display device 3. The converted signal is converted into an interpretable signal and sent to the display device 3.

As a result, facsimile information is displayed on the display device 3 (S20).

As explained above, according to this embodiment, it is possible to receive a mixture of screen information compliant with the Captain Expression Protocol and information not compliant with the Captain Expression Protocol, and the display format can be automatically changed. Moreover, this information can be displayed on the display device 3 at high speed.

Further, when displaying screen information compliant with the captain expression protocol on the display device 3, guidance information is displayed, so the next operation can be easily performed.

(Effects of the Invention) As described above, according to the present invention, the display device has a display device capable of displaying more dots than the number of display dots stipulated in the Captain Expression Protocol, and can also display information that is not compliant with the Captain Expression Protocol. Since I configured it so that it can be displayed,
