DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an object-selection type information communication method and apparatus for selectively using audio, video and character input / output means for communication.

[0002]

2. Description of the Related Art With the advancement of wireless communication technology and LSI for wireless communication devices, portable wireless devices having high functions have become available at low cost. Also, a speech recognition technology for converting speech into characters using speech recognition and a speech synthesis technology for converting characters into speech using speech synthesis have been rapidly advanced. In the wireless communication device described in Japanese Patent Application Laid-Open No. 5-188895, a method of reducing the amount of information in voice signal transmission using voice recognition and voice synthesis techniques is disclosed.

FIG. 6 shows an example of a block configuration of a conventional radio communication apparatus described in the above publication. The antenna 57 is coupled to the transmitting unit 53 and the receiving unit 60. The transmission unit 53 supplies transmission power to the antenna 57 in the transmission mode.
2. An audio processing unit 51 and a microphone 50 are arranged. The voice signal input from the microphone 50 is input to the voice processing unit 51, and the voice is recognized by extracting the feature parameter of the voice, and the recognition result corresponds to a predefined character code or word code. Compresses the audio information. For example, if the voice is Japanese, 5
It is coded corresponding to the character code corresponding to the zero sound, and the word code is coded when the voice is in English or the like. The output of the compressed data is input to the modulation unit 52.

The modulation section 52 modulates an oscillation signal from an oscillator (not shown) with the code output of the audio processing section 51. The modulation output of the modulation unit 52 is transmitted to the transmission unit 53, and high-frequency power corresponding to the modulation output is supplied from the transmission unit 53 to the antenna 57, and the antenna 57 emits radio waves for wireless communication.

[0005] In the receiving mode, the receiving unit 60
The audio signal is extracted by amplifying and detecting a high-frequency current generated by an external radio wave.
The output of 0 is input to the audio processing unit 51. The audio processing unit 51 decodes the signal from the receiving unit 60 and synthesizes audio based on the result to obtain an audio signal waveform. By supplying the audio signal waveform to the speaker 62, an audio output is obtained.

FIG. 7 shows a voice processing unit 5 of a conventional wireless communication apparatus.
FIG. 2 is a diagram showing a detailed block configuration of one example. An audio signal from the microphone 50 is supplied to a microphone amplifier (AMP) 501.
After being appropriately amplified by the above, the signal is input to an A / D (analog / digital) converter 502 and converted into a digital signal.

[0007] From the audio signal A / D converted by the A / D converter 502, a characteristic parameter which is a characteristic portion of the audio waveform is extracted by a voice recognition unit 503. The voice is recognized by this processing. The voice recognition processing here includes redundancy, meaningless fluctuation, and the like included in the voice waveform input from the microphone 50.
The processing is to remove noise and the like so as to increase the efficiency of the subsequent coding processing. The coding unit 504 codes the result of the voice recognition by the voice recognition unit 503 into a character code or a word code based on the information of the table 505 defined in advance.

On the other hand, what is received by the receiving section 60 shown in FIG. 6 is a transmission signal, and this transmission signal is also a coded speech recognition result as in the case of transmission.
Therefore, since such a received signal cannot be recognized as voice as it is, it is supplied to the decoding unit 506, where the output signal of the receiving unit 60 is decoded.

[0009] Further, based on the decoded output, the speech is synthesized by the speech synthesizer 507 to obtain a speech corresponding to the received signal. In this speech synthesis processing, the information in the table 505 is referred to. The output of the voice synthesizer 507 is converted into an analog signal by the D / A converter 508, amplified by an amplifier (AMP) 509, and transmitted to the speaker 62.

In general, an audio waveform is formed by synthesizing a sine wave whose amplitude and phase gradually change.
A short-time power spectrum is calculated by Fourier integration in a time section of about 0 ms, and a feature of the voice can be obtained.

[0011]

The above-mentioned conventional wireless communication apparatus does not have a function of transmitting the state of the transmitting side to the other party, so that the transmitting side cannot output sound or the other party in a noisy environment. There is a problem that the communication partner cannot understand at all even if the voice of the side cannot be heard.

In addition, since the transmitting and receiving sides cannot select communication means such as images, voices, characters, and the like, when a communication fee is calculated based on a data amount, there is a problem that a transmitter and a receiver cannot select an inexpensive fee. .

Accordingly, the present invention has been made in view of the above, and a common communication mode in which image data, voice data, and character data can be communicated on the transmitting and receiving side during transmission and reception is provided by the communication mode presented by the transmitting and receiving side.

If there is a response to the profile data, the profile data is analyzed (STEP 18), and the encoded data to be used is primarily determined (STEP 20).

Next, the communication equipment on the transmitting side performs a logical OR operation on the encoded data to be transmitted to the receiving side and the primary determined encoded data, and finally determines the data to be encoded (image, voice, character, etc.). (STEP 21), transmission of encoded data is started (STEP 22).

When the logical data of the profile data determined next and the profile data on the transmission side corresponding to the table of FIG. 3 is ORed, the result shown below is obtained.

0110011 110011 1 100... Profile data 1110111 111111 1 111 on the receiving side shown in FIG.
... Profile data 011 on the transmitting side shown in FIG.
0011 110011 1 100... OR of profile data in FIGS. 2 and 3

According to this result, since the voice coding method (major classification) is 0: impossible, the voice coded data is not transmitted. Since the video encoding method (major classification) is 1: possible, the video encoded data is transmitted as MPEG-1 video data, assuming that the higher-order bits have priority. AC-3 and DTS 1: Possible but not used. Character encoding method (major classification) is 1:
Although possible, the method of sub-classification is not clear and will not be used this time. Other coding methods (major classification) are 1: possible, but small classifications are 0: impossible, so they are not used.
