Distinguishing between EG audio system and VCELP system,
For example, in the case of the MPEG audio system, in step 56, the decompression decoding process (compressed coded data) of the audio coded data is performed using the arithmetic program of the decompression calculation process stored in the data storage memory 31 suitable for the MPEG audio system. Is converted into decompressed (real area) data). In the subroutine flow of this operation firmware, operation firmware common to the decompression decoding method (for example, in order to convert from the frequency domain to the real domain, operation such as IFFT (Inverse Fast Fourier Transform) is used. Can be commonly used in decompression / decoding programs such as MPEG1 and JPEG.) (Common arithmetic function for converting compression-encoded data into decompression (real area) data) 47, a memory built in the microprocessor 30 (for example, The program stored in the ROM 301) is used. Next, the microprocessor 30 determines whether or not the character information is present in the data storage memory 31 in step 57, and if yes, the step 58.

If not all can be displayed on the liquid crystal screen of, the display control 44 according to the screen menu display 35 controlled by the microprocessor 30 by the operation of the four switches 24 of the two selection switches, the menu switch, and the decision switch.
All the display contents can be confirmed by using the screen scrolling function and the display enlarging or reducing function. When a plurality of pieces of information arrive at the receiving device (pager terminal) 10 at the same time, the microprocessor 30 causes the ROM 301 to read the ROM 301, for example.
In the control program stored in, the output priority of information is predetermined among the four switches 24, and the microprocessor 30 controls accordingly and outputs to the display unit 21 and the voice output units 27 and 28. Can be done. Further, as an I / O interface control function, for example, by connecting the memory card 26, the microprocessor 30 reads the encoded compressed data received by the receiving units 37 to 40 and stored in the data storage memory 31 to read the IC. Card / IF42
The multimedia information can be stored as the encoded compressed data as it is by being recorded in the IC card 26 via the. In addition, the receiving device (pager terminal) 10
By connecting the connector 25 for external connection of the computer to a personal computer, a television connection adapter, or the like, the compression-encoded multimedia information stored in the data storage memory 31 or the decompression-decoded multimedia information stored in the microprocessor 30 is transmitted to an external device. It is possible to transmit, and for example, the contents that are difficult to see on the display 21 of the main body of the receiving device 10 can be confirmed on the large screen of the external device.

As described above, in the embodiment of the present invention, as shown in the block configuration of FIG. 1, a dedicated LSI or a similar IC or the like is not provided for each decompression calculation method. However, as is clear from the decompression operation processes 54 and 55 in the process flow described in FIG. 4, all the single single-chip microprocessors 3
0 is doing. When the character information is obtained from the baseband demodulation unit 40, the microprocessor 30 executes code conversion processing.

Here, the identification code (attribute data) stored in the data storage memory 31 described above is represented by the attribute code (indicating audio data or image data) and the compression mode. In the case of image compression as a compression mode, MPEG (Moving Picture coding Expert)

By storing it in the built-in memory of 0 (for example, ROM 301), the required memory capacity for the data storage memory 31 can be dramatically reduced. In the above-described embodiment, the case where the arithmetic programs for various decompression arithmetic processes are stored in the data storage memory 31 has been described. However, if the capacity of the ROM 301 in the microprocessor 30 increases, it is possible to write in the ROM 301. Become. On the other hand, as described in the above embodiment, among various kinds of decompression operation processing, among the operation firmware that converts compressed data into decompressed data, the operation firmware common to the compression encoding method is used by the microprocessor 3
