Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an image display communication terminal device that receives melody data together with image data.

(Prior Art) There is a videotex system as a system that receives data from the outside and displays the received data as an image. This Videotex system uses a telephone line as a transmission medium to transmit not only image data but also melody data coded for music notes, and the terminal side displays images and
Convert melody data into sound and play it. The above-mentioned melody data is transmitted when performing BGM, special sound effects, force 2 orchestra, or the like.

Conventionally, the Videotex terminal processes received data as shown in the flowchart shown in FIG. That is, when data is received, it is determined in step 851 whether it is melody data or not, and if it is melody data, music processing is performed, and if it is not melody data, image processing is performed. In the music processing, the melody data received in step 852 is stored in the melody card, and after the reception of the melody data is completed, the melody is outputted according to the data stored in the melody box AM (steps 853, 854). On the other hand, in image processing, data is cleared on a clear screen in step 855.
It is determined whether or not the current state is C8. Clear screen C8 is i'tfIJ control data that is added to the beginning of one screen's worth of image data and instructs to clear the display screen. Therefore, when the data is a clear screen C8, in order to receive the subsequent image data, two image boxes (one display, etc.) are initially set (step 856).Furthermore, the melody is stopped,
The melody RAM is cleared in preparation for receiving the next melody data (steps 857 and 858).

If the screen is not clear C8, the received image data is displayed and decoded in step S57.

(Problems to be Solved by the Invention) The melodies that are added to the screen and transmitted may be used as 100M for images, sound effects, karaoke, etc. as described above. Among these, especially in karaoke and the like, recipients may request to play the same song over and over again. In this case, the communication terminal device with the above configuration specifies the same screen number and receives the same data again, but in addition to being required to pay a data reception fee (information fee) for the number of receiving ports, a fee proportional to the connection time is required. Telephone charges (telephone charges) will also be required.

As described above, conventional image display communication terminal devices are mainly configured with an image display function, and do not have sufficient functions for melodies such as karaoke.

Therefore, in order to play the same song multiple times, information fees and communication fees are required depending on the number of times the song is played.

The present invention has been made in view of the above-mentioned points, and it is an object of the present invention to provide an image display communication terminal device that can reduce the burden of fees even if received melody data is played multiple times.

[Structure of the invention]

(Means for Solving the Problems) The present invention is characterized in that it is configured to play back music from melody data stored in a buffer memory in response to a playback request when the communication line is disconnected. do.

(Function) With the above configuration, the melody data transmitted through the communication line and stored in the buffer memory when the communication line is connected can be controlled so that it can be played back as music even when the communication line is disconnected, so the melody data can be played multiple times. Even when performing, it is possible to reduce the burden of fees.

(Example) Hereinafter, the implementation of the image display communication terminal device of the present invention will be described with reference to the illustrated box.

In FIG. 1 showing an embodiment of the present invention, 10 is a microprocessor (hereinafter referred to as CP) that decodes received data.
) receives a clock from the oscillator 11 and generates ELo.
It operates according to the program stored in M12. Image R, AM 13 stores image data among the received data, and melody data (14 stores melody data).
j Oh, the above 0M12. The operation is defined by a chip enable signal from the RAM 13 and the L4 selector 15.

The data stored in the image RAM 13 and melody LAM 14 is supplied from a data receiving circuit 16 to which a telephone line is connected. The CPU 10 decodes the image data stored in the image module AM 13 according to the program in the module 0M13, and displays the display data in the image display circuit 17.
The data is stored in a display memory (not shown) within the computer. Thereby, the image display circuit 17 reads display data from the display memory in synchronization with the raster scan, and displays the image on a CRT or the like. On the other hand, the melody data stored in the melody recorder 14 is given to the melody generation circuit 18 by the CPU 10 and output as music.

Next, the operation of the embodiment having the above configuration will be described with reference to the flowcharts shown in FIGS. 2 and M3.

When the data receiving circuit 16 receives data via the telephone line, the C, PU 10 determines whether it is melody data or not in step 821, and if it is melody data, it performs music processing, and if it is not melody data, it performs image processing. . In music processing, when the beginning of melody data is received, melody R, AM 14 is cleared (step 822.
23) L. Store the received melody data in the melody storage AM 14 (step 524).

When the reception of the melody data is completed, the CPU 10 outputs the melody by transferring the data stored in the melody amt 14 to the melody generation circuit 18 (steps 325 and 826).

On the other hand, in image processing, CPU10 is Stella S27
Determine whether the data is clear screen C8 or not. When the data is a clear screen C8, the display memory in the image storage AM 13 and the 1-image display circuit 17 is initially set to receive one continuous image data (step 828).
), the melody being played is stopped (step 529).

If the received data is not clear clean C8, the received image data is stored in the image a7 VM13, and the display is dead in step S30. The decoded display data is applied to an image display path 17, and an image is displayed.

As described above, in the data reception process of this embodiment, 1 melody R, AM 14 is cleared not when clear screen C8+ is received, but when new melody data 1 is received. Therefore, the received data is an image.

If there is only data but no melody data, the melody AM 14 is not cleared and the previous melody data is held.

r Next, I will explain about the end of the reception of the Koubunya Biwakijin Tetsuchi reception data.

In step 831, it is determined whether the key input from the remote control (not shown) is a melody replay key.

In the case of a re-appearing oyster, if there is a melody RA in melody AM 14, the CPU 10 will read melody RA.
The melody data is read from M14 and transferred to the melody generation circuit 18, which outputs the melody (steps 832, 833).

-When a key other than the reappearance key is performed, the follow-up key is used.
As before, key processing is performed according to the key's human power (step 534).

:Ma1 According to the above melody function, the melody can be played by key operation even after the telephone line is disconnected.

Tera: Also, even if you are at home receiving normal data connected to a telephone line and receive only image data without melody data added, you can play back the previously received metalody data.

That is, in the state 70-chart of the embodiment shown in FIG. 4, the telephone line is switched from a disconnected state (off, fin) to a connected state (on2i/), and image and melody data are received (step S41).゜542). In this state, as shown in the flowchart shown in FIG. 2, the image 1#! Displays and musical performances are made.

Next, if the received data is only image data (step 543), only image display is performed, but since the melody data received in step 842 is held in the melody RAM i4, the melody data received in step 842 can be displayed by key operation. Music performance can be performed as shown in Figure 3. The above melody data is erased when the melody data is received in step 844, and the newly received melody data is held in the melody RAM 14.

If it is desired to reproduce the melody data received in step 844 many times, the telephone line is disconnected and placed in an offline state (step 545), and in this state a key operation is performed to request melody reproduction.

In this case as well, since the melody data received in step S44 is held in the melody RAM 14, music is played as shown in FIG. At this time, since the telephone line is disconnected and the user is offline, no telephone charges or data reception charges will be charged.

As described above, in this embodiment, music can be played back from the melody data in the melody R, AM 14 even when the telephone line is disconnected, that is, the melody can be controlled on the end side. Therefore, when playing a long melody multiple times, such as in karaoke, once the melody data is received, the telephone line is disconnected, and the melody is played multiple times by key operation, telephone charges and data reception charges will be charged. It is economical as it does not cause damage.

In addition, this embodiment clears the melody RAM 14.
This is done when the melody data is actually received, not when the clear screen C8 that instructs to clear the screen is received, so if image data such as 80M to which melody data is not added is received, the previous The received melody data can be read out from the melody RAM 14 and played back.

〔Effect of the invention〕

According to the present invention, since the playback of the melody can be controlled on the terminal side, it is possible to play music from the melody data in the buffer memory even when the communication line is disconnected, and the melody data can be played multiple times. It can also reduce the burden of fees.
