[0002]

2. Description of the Related Art Conventionally, as independent devices, a moving picture player, a text display, a portable music player, a reading player, a portable radio, a portable television, a digital camera, a digital camera,
Various portable devices such as an IM device and a GPS device have been developed. PDA (Personal) is a portable device that can realize several functions with one device.
A portable terminal device called Digital Assistants) and a book-type portable personal computer are known. These are provided with basic functions such as schedule management and telephone directory management in advance from the beginning. If necessary, add an adapter device to connect to a mobile phone, connect to a digital camera, etc. The function of each adapter device can be used additionally (afterwards). A portable personal computer is a highly versatile device that can execute various application software (programs).
For example, they may have functions such as a moving image playback and a music player, which are executed by a software program of an application.

[0003]

In the above case, even if individual entertainment devices are reduced in size for portable use, if they are realized as individual devices, only necessary ones are carried around. Even so, it is necessary to carry more than one. In recent years, multifunction devices with multifunctional functions have been gradually created, but when the number of functions increases to three or four, the size of the device itself increases, and the price of the device itself increases. I will. Further, even in the case of a PDA, it is necessary to carry a plurality of adapter devices dedicated to each function in the same manner as described above. Assuming that the PDA has one basic function such as schedule management as a basic concept, when another function is required, another additional function is added or an application program is installed. It is in the form of increasing by adding such software. For example, the addition of a dictionary function can be extended by installing an application program.
GPS function module, MODEM / L for A body
An example is seen in which various functional modules such as an AN module and a wireless module such as BLOUTOOTH are connected as separate cassettes. However, these functions are additional functions given to a PDA having schedule management and other basic functions as a single unit, and are not intended to realize a main device. Therefore, PDA
When it is considered as a multifunctional device, it is difficult to reduce the size and cost of the entire device including the PDA and the adapter. In addition, when the above-mentioned functions of video playback and music player are given to highly versatile devices, the high performance and high consumption required when running heavy application software (software with a large amount of data to be processed) Since power is required, it is difficult to reduce the cost, and there is a problem in portability because the capacity of the battery is increased.

Various other data provided) are prepared by each content data provider, and are used by selecting from them. Note that there are various forms of the method of providing the content data. One is a case where a storage medium in which content data is stored in advance is directly sold at a store. Another case is a case where only content data is sold by writing data to a storage medium already owned by the user using a dedicated writing device. Further, as one feature, the functional device 19 may be provided with a function of connecting to a mobile phone so that content data is acquired via the Internet and written to a storage medium. When the storage medium 1 is attached to the functional device 19, the storage medium 1 functions as a source of content data for the functional device 19, and the content data is sequentially transferred to the functional device 19 and the device main body 17 in S 8. . Further, additional program data of S5 or more is transferred from the storage medium 1 as needed. Finally, if the functional device 19 is an MPEG4 player, in S9, the content data stored in the storage medium 1 is
It operates as a portable device output as voice or the like. In this flowchart, the order is such that the functional device 19 is mounted on the device main body 17 and then the storage medium 1 is mounted. However, the storage medium 1 is mounted on the functional device 19 and then mounted on the device main body 17. You may do it. This flowchart is an example of an element procedure necessary to finally complete the operation as a portable device, and the order of the element procedures does not influence the present invention in completing the operation function.

Is detected and the game proceeds.

(Embodiment 2) Next, the multifunctional portable device 11 according to the present invention is implemented by using MPEG4, MPEG2
Will be described. As described above, MPEG4 and MPEG2 record video and audio, etc.
This is a predetermined format (format) determined for reproduction. In order to reproduce the data of MPEG4 or MPEG2, for example, a functional device 19 having a dedicated program and a processing device such as a CPU is required. In some cases, the reproduction function is performed by the functional device 19 configured of dedicated hardware that does not require a general-purpose CPU. Specifically, the dedicated program is stored in the ROM 43, and is stored in the MPEG4 and MPEG2.
Control means 31 as a processing device for efficiently processing
Is used. And the MPEG processed in this way
4 and MPEG2 information are output by the display device 13 and the speaker 35 of the device main body 17. As a more specific example, FIG.
It is a block diagram for making it a portable device of EG4. At first,
The device body 17 and the functional device 19 are combined into an MPE

Further, in this embodiment, the module 51 alone has a photographing function as a digital camera, and the specification may be such that the device main body 17 is used only when an image is to be displayed. However, by combining the functional device 19 and the device main body 17, a more complicated operation of the operation means 15 can be performed. In addition, since the captured image can be stored in the storage medium 1, if the storage medium 1 is connected to a personal computer or the like, the image data can be imported to the personal computer, and the module 51 has a USB function. Sometimes, it is possible to directly import image data into a personal computer. In the above example, a digital camera has been described as an example, but the module 51 may have a function as a video camera, and may have the same configuration as described above. In this case, the moving image data can be stored in the storage medium 1 according to the above-described standard such as MPEG.

(Embodiment 4) Next, FIG. 8 shows a case where the multifunctional portable device 11 according to the present application is a television or radio as an example of a module group whose contents are directly provided from a broadcast network or a communication network. It will be described using FIG.
