[Embodiment of the invention]

 Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic configuration diagram showing an entire system including the interface device of the present invention, and a circuit in the interface device is shown in a block diagram.

Referring to FIG. 1, an interface device 100 of the present invention is connected between a mobile phone 10 and a television 12 and receives data from a data center 18 through the Internet 16, a provider 14 or from a data center 18 through a carrier 20. The video data, the audio data, and the like are temporarily stored in a memory therein, transmitted to the television 12, and a signal generated inside the apparatus is transmitted to the provider 14.

The configurations and functions of the mobile phone 10, the television 12, the provider 14, the Internet 16, the data center 18, and the carrier 20 are the same as those of the related art, and a detailed description thereof will be omitted.

Next, main components inside the interface device 100 will be described. The mobile phone interface 102 is connected to the provider 14 through the line of the mobile phone 10, and an operation generated by another interface 106 (an interface for the remote controller 204 and the like) of the interface device 100 is shaped by a CPU 108 described later. This part is for dividing the processed data appropriately and sending it to the line side for each data block.

The CPU 108 classifies the data chunk received from the mobile phone interface 102 into an image, a sound, a text, and the like, shapes the data, and outputs the data to the video chip 120 and the audio DA / AD chip 110 in the form of an image and a sound. . It also detects signals generated by the user's remote control 204 and other remote control operations sent from the IrDA (infrared ray) interface 106, and controls operation such as connection start and connection completion and operations on the homepage according to the pattern. I do. Note that wireless may be used instead of the IrDA (infrared) interface.

The CPU operation memory 116 is a temporary storage area necessary for the operation of the CPU 108. The contents disappear when the power is turned off. This is used to temporarily store image data and audio data.

The flash ROM 112 is a rewritable storage area that does not disappear even when the power is turned off. It is used to store some data such as the main body of a program (software) for operating the CPU 108, various user information, and a state before the power is turned off.

An IrDA (infrared) interface 106 is the same as an infrared receiver provided in a television, an audio device, or the like. This is a part for detecting a flickering pattern of infrared rays emitted from an infrared light emitting device such as the remote controller 204, converting the data into data, and sending the data to the CPU side. This is used by the user to perform various operations.

A video chip 120 with a built-in NTSC (PAL) converter and a video memory 118 are parts for outputting image information developed in the video memory by the CPU 108 to a television connection terminal.

The audio DA / AD chip 110 is a part that converts a digital signal sent by the CPU 108 into an analog signal and outputs the signal to a sound output terminal as sound. At the same time, it has a voice input terminal and has the function of converting voice into analog electric signals and digital data. If the processing capacity of the CPU 108 is high, the voice input from the microphone is digitally compressed and sent to the Internet. Functions such as telephones can also be added.

The USB interface (expansion) 206 can be connected easily to a device (for example, it can be connected to a device while the power is on, and power can be supplied from a main unit via a cable without a power source from the device). This is an interface with an increasing number of devices. Devices that can be connected to this interface include keyboards, mice, printers, scanners, or game pads (controllers), speakers, small cameras that can be used in video conferencing, etc., and music devices that are used in MIDI, etc. There are things to connect.

The card interface (expansion) 104 is for connecting various PC cards for a notebook personal computer. When music distribution is used, a large storage area is required. , MPEG moving picture data, etc.

Next, the operation and operation method of the present apparatus will be described. The user turns on the power of the television 12 first, and then turns on the mobile phone 10 and the interface device 100 in this order. Internet connection is performed according to a menu displayed on the television screen by operating the remote controller 204. At this point, the interface device 100 automatically operates the mobile phone 10 from the mobile phone interface 102, calls the provider 14, and connects to the data center 18 through the Internet 16. Note that the mobile phone 10 may be operated to connect to the data center 18 instead of the menu on the television screen.

The remote controller 204 has a key arrangement of a mobile phone, which can be operated by using numbers and kana keys on the remote controller in the same manner as the character input of the mobile phone so that the user can use characters without any discomfort. It is desirable that the configuration be substantially the same as that described above.

The user operates the remote controller 204 (or the mobile phone 10) to select a movie or music data to be watched from the data stored in the data center 18 in accordance with a menu displayed on the television screen. , And instructs to download data to the interface device 100. Data (image data, audio data) downloaded from the data center 18 to the interface device 100 via the Internet 16 is temporarily stored in the CPU operation memory 116 under the control of the CPU 108. Once stored, the user hangs up the mobile phone. Under the control of the CPU, the stored data is subjected to character image formation, page shaping, image / sound data conversion, and the like, and output to the television via the video chip 120 and the audio chip 110.

Although the above-described operation and operation method are basic, the present interface device can be used for browsing various homepages on the Internet and transmitting and receiving electronic mails. The interface device 100 is used to output image data and audio data input through the mobile phone 10 to the television 12 when browsing a home page or transmitting / receiving an e-mail.
