[Industrial applications]
The present invention relates to a multimedia communication device.
[0002]
[Prior art]
Some modems connected to a computer or the like can transmit or receive voice and data (file transfer or fax) at the same time. With this modem, a fax document can be sent or a file can be transferred while making a telephone call. On the other hand, a document with a voice message is file-transferred using a data modem, and the receiving side views the document and listens to an attached voice message after the transfer is completed. However, in this method, the receiver cannot output or reproduce the document or the sound until all the communication processes are completed. If a document is received by so-called fax, it can be seen that the document is sequentially displayed on paper in raster units during reception. Similarly, it is possible to reproduce sound from a speaker simultaneously with a document.
[0003]
[Problems to be solved by the invention]
However, when transmitting and receiving a document and voice simultaneously, if the receiving side outputs the document and plays back the voice at the same time as the reception starts, even if the voice is missed at the beginning, the voice returns to the original place and listens. I can't fix it. On the other hand, if the voice is recorded in the storage unit, it can be reproduced later. However, in this case, the voice message can be heard only after the communication is completed.
[0004]
An object of the present invention is to solve such a problem and to provide a device capable of listening to a voice message at an arbitrary timing.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, a first invention of the present application is a storage means for pre-storing voice and data to be transmitted, a data transfer means capable of simultaneously transmitting and receiving voice and data, and transmitting the voice by the data transfer means. The data transfer means so as to simultaneously transmit the voice stored in the storage means in addition to the data being transmitted in accordance with an instruction given while transmitting the data stored in the storage means without performing And control means for controlling.
[0006]
Further, a second invention of the present application is an apparatus for communicating voice and document data stored in a storage unit by data transfer means capable of simultaneously transferring voice and data. If the time required for the transmission is shorter, the document data transmission is started, and then a voice transmission start notification is sent from the receiving side, or the remaining time of the document data transmission is the time required for the voice transmission. The transmission of the voice is started at the time when they become equal.
[0007]
【Example】
FIG. 1 is a block diagram of one embodiment of the present invention.
[0008]
In the figure, 1 is a control unit, 2 is a storage unit, which stores document data and audio data. Reference numeral 3 denotes a voice / data modem as an example of a data transfer means capable of transmitting and receiving voice and data at the same time, 4 denotes a speaker, 5 denotes a handset hook, 6 denotes a printing unit, 7 denotes an input unit for inputting an instruction to the device, 11 is data control means, 12 is audio output means for outputting audio data to a speaker, 13 is communication control means, 14 is document output means, 15 is document data read / write means, 16 is audio data read / write means, and 17 is hook 5 ON / OFF detecting means, 18 is a clock, 21 in the storage unit 2 is a document data storage area, 22 is a voice data storage area, and 24 is a storage area for storing a fixed voice message.
[0009]
Next, FIG. 2 shows a processing flow at the time of transmission of the device according to the embodiment of the present invention.
[0010]
First, in a state where the document data is stored in the document data storage area 21 and the voice data is stored in the voice data storage area 22, transmission of the mixed data of the document and the voice is instructed from the input unit 7, and the data control is performed. The means 11 reads the data size of the document and voice data by means of the reading and writing means 15 and 16. According to the data size, the required time (Td, Tv) required for transmitting the document and voice data is calculated (S-1, S-2). The data control means 13 starts an initial protocol with the communication partner (S-3). When the initial protocol is completed, the required time Td calculated previously by the 11 data control means is compared with Tv (S-4), and the required time (Tv) for transmitting the voice data is longer than that of the document (Td). If they are larger or equal, the communication control means 13 outputs information to the voice data modem 3 so as to start the transmission by mixing the voice data and the document data (S-10). Here, the document data and the voice data are read out from 21 and 22 for 15 and 16 and are sequentially transmitted.
[0011]
On the other hand, if the required time (Tv) for transmitting the voice data is shorter than that of the document (Td), the communication control means 13 replaces the voice data stored in the voice data storage area 22 with the data to be transmitted. A fixed voice message (for example, “Fax with voice” etc.) for notifying that the document is a voice document is mixed as voice data with the document data, and transmission is started by the voice data modem 3 (S-5). Here, the fixed voice message is read from 24 for 16 and the document data is read from 21 for 15 and sequentially transmitted. At this time, the data control means 11 obtains the transmission start time from the clock 18 (S-6). Immediately after starting the data transmission, the communication control means 13 starts monitoring whether or not a voice data start request command is sent from the receiving side (S-7). 11 obtains the current time sequentially from 18 (S-8), calculates the elapsed time from the start of data transmission, and compares it with (Td-Tv). At the time (S-9) when the elapsed time becomes equal to (Td-Tv), the sound data to be sent is mixed with the document data and transmission is started. When the transmission of the mixed data is completed (S-11), the communication control means 13 executes a communication termination protocol (S-13).
[0012]
The operation of the device of this embodiment at the time of reception will be described below.
[0013]
At the time of reception, when the communication control means 13 detects the reception, the communication control means 13 executes an initial protocol. When data is transmitted, the communication control means 13 divides the data into a document data section and a voice data section. Is printed on the printing unit 6, and the voice data is reproduced on the speaker 4 by the voice output unit 12 and written into the voice data storage area 22 by the voice data read / write unit 16. Here, when the handset is lifted up and on-hook, the hook ON / OFF detecting means 17 detects it from the handset hook 5, and the data control means 11 sends a voice data transmission start request command through the modem 3.
[0014]
In response to the start request command, the transmitting side branches from step S-7 to step S-10 in FIG. 2, so that audio data is transmitted. Therefore, the user can hear the sound accompanying the document.
[0015]
As described above, in the present embodiment, when transmitting, if the time required for transmitting the audio is shorter than the time required for transmitting the document, the document transmission is started first, and a voice transmission start notification is received from the receiving side. Wait until it is sent and start sending audio.
[0016]
When the receiving side determines that the document with voice has been received, it sends a voice transmission start notification to the transmitting side when a certain switch is pressed or the handset is taken (on-hook).
[0017]
Therefore, in this embodiment, it is possible to listen to the sound attached to the document during reception by giving a signal such as taking a handset after the receiving side knows that the reception of the document has started. Further, the receiving side is not limited to the operation of taking the handset, and for example, a predetermined instruction may be given to the input unit 7.
[0018]
【The invention's effect】
According to the present invention, the voice message can be heard at an arbitrary timing on the receiving side, and the usability is improved.
