Thus, when a user desires to listen to music, the user operates the operation key to select desired music data from a flash memory, and it is outputted from a speaker, a headphone, etc., as a reproduced music via a D/A converter and an amplifier.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable radio telephone terminal capable of recording and reproducing voice information and character information including music.

[0002]

2. Description of the Related Art A conventional portable radio telephone has a function of transmitting and receiving voice or voice and character information associated therewith.
In addition, the portable music recording / reproducing apparatus records audio information including music from a music source and reproduces it. That is, the portable radio telephone and the portable music recording / reproducing device are separate devices, and both devices have to be carried around and used separately.

[0003]

In the conventional portable telephone terminal, only conversation by voice can be performed, and there is no function of recording and reproducing non-voice information such as music and accompanying character information. In order to listen to audio information including music, it is necessary to use a separate portable music recording / reproducing apparatus, and it is necessary to carry each of them and use it properly according to the application, which is inconvenient and difficult to handle.

An object of the present invention is to provide a portable radio telephone with a function of recording and reproducing distribution information such as music so that the reproduced music can be output and character information can be displayed on a screen. A wireless telephone terminal is provided.

[0005]

In order to achieve the above-mentioned object, the invention according to claim 1 of the present invention is directed to a band radio telephone terminal for transmitting and receiving voice information, which is distributed from a center database. Receiving means for receiving information, memory means for downloading and storing the received distribution information, selecting means for selecting information from the memory means, and reproducing means for reading and reproducing the selected information from the memory means. And output means for outputting reproduced information.

[0006] The invention according to claim 2 is based on claim 1.
In the portable telephone terminal described above, the distribution information is audio information including music, and the distribution information includes a protocol capable of downloading the audio information including music, and an output unit that outputs audio including reproduced music. And

According to a third aspect of the present invention, in the portable telephone terminal of the first aspect, the distribution information is audio information including music or character information related to the audio information including the music. It is characterized by having a protocol capable of downloading voice and character information including music, a data format capable of mixing voice data, character information and control commands for controlling character information, and a display device capable of displaying character information.

[0008] According to the above configuration, a single portable radio telephone terminal can perform a normal voice call and also has an information recording / reproducing function, thereby outputting reproduced music and displaying character information on a screen. On the display.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram for explaining a communication system in which the mobile phone terminal of the present invention is used. In the figure, a portable radio telephone 1 includes a center 3 having a music source and a related character information database and a public base station 2.
, And wirelessly communicates data between the antenna 1a of the portable radio telephone 1 and the antenna 2a of the public base station 2. By operating the operation key 1b of the portable radio telephone 1, a desired music is transmitted from the music source located in the center 3 to the portable radio telephone 1, and it is received and stored. The related character data is displayed on the LCD 1c of the portable wireless telephone 1.

FIG. 2 is a block diagram showing the configuration of the portable telephone terminal of the present invention. In the figure, 11 is a speaker (headphone), 12 is an amplifier, 13 is a D / A converter,
14 is a CODEC (voice compression / decompression logic), 15 is a flash memory (ROM), 16 is a buffer RAM, 1
7 is a demodulator, 18 is an RF unit, 19 is an antenna,
Reference numeral 20 denotes a CPU, 21 denotes an MMI control, 22 denotes operation keys, and 23 denotes a liquid crystal display (LCD).

The music source received by the antenna 19 is R
The data is received by the F unit 18, demodulated by the demodulator 17, and temporarily stored in the buffer RAM 16. Here, in the case of a normal wireless call, the voice information is CODEC.
The audio is output to the speaker 11 or headphones through the audio signal 14. The temporarily stored data is stored in a flash memory 15 for storing music source data.
The flash memory 15 has a capacity for recording music sources for several songs. When the user wants to listen to the music, the user operates the operation keys 22 to select desired music data from the flash memory 15, and as the music reproduced via the D / A converter 13 and the amplifier 12, the speaker 11 or Output from headphones, etc.

Next, another embodiment of the present invention will be described. FIG. 3 is a view showing an example of a screen for displaying character information following the display unit of the portable radio telephone, and FIG. 4 is a view for explaining an example of a data format for the display shown in FIG. In the figure, in addition to voice information, character information accompanying the voice is displayed on an LCD 1 serving as a display unit of the portable radio telephone 1.
c. For example, in the case of music, the lyrics are displayed, and in the case of language learning speech, sentences and spellings are displayed.

As shown in FIG. 4, the accompanying character information is
Since it needs to be displayed before the actual audio is output,
On the data, character information is recorded first, and thereafter, audio data which is the content of the character information is recorded.
In the case of music lyrics, if the actual lyrics are displayed as characters, it takes time to read them, so the lyrics are displayed in advance at a certain interval rather than displaying the lyrics in synchronization with the music voice It is more effective.

At the same time, by inserting a command for controlling an underline or the like between the voice data after displaying the character, a real-time pointer can indicate the displayed character information. For example, where the lyrics are currently being sung can be known by the underlining of the characters. Therefore, desired data can be obtained from any place where wireless communication can be performed with the portable terminal, and can be downloaded to a semiconductor memory with less trouble or trouble.

[0015]

As described above, in the portable telephone terminal of the present invention, since one portable telephone terminal has both functions of the telephone terminal and the distribution information terminal, it includes music in addition to the voice call and the voice call. Voice data or voice data and character data attached thereto can also be used. Therefore, a compact mobile phone and information terminal with excellent portability can be obtained, and the user can obtain more information.
