Description

Small display device that can display screen of mobile phone information device, play video and receive voice mail. {Portable voice and active picture player}

The present invention relates to a display device of a portable information device, and relates to screen display of various information devices, video playback of a small data storage device and voice mail message transmission.

As the high-speed wireless data communication service becomes available, the application of the existing desktop type information device is shifting to the small mobile communication device, and its performance is also rapidly developing, and the light weight is becoming smaller.

However, existing mobile phones and information devices have limitations in display devices despite the improvement in performance. In addition, the large screen of the display device is essential for the use of a small modular information device that performs one function separately and the use of a wireless data service. It is necessary to utilize.

In addition, with the development of mass storage devices, it is expected that the utilization will shift from the existing voice-oriented data playback (eg, MP3, MDPLAY, etc.) to video playback. . Existing playback devices have been used as displays of recorded playback tapes, such as camcorders or image cameras, which are separate hardware equipment, but as these data are digitized, it is necessary to directly play back the memory storing video data.

In addition, voice recording and transmission are more and more demanded due to the increase of in-vehicle activity time, and there is a need for an apparatus for simply transmitting a voice recording message to a designated mail due to the inconvenience of transmitting a text message due to the in-vehicle environmental constraints.

Therefore, the present invention transmits the screen information data of the mobile phone through wired / wireless communication and reproduces it on the small TV screen in order to switch the small display screen of the mobile phone and the information device. Video memory with interface module for receiving data such as flash memory to convert data into small TV screen by receiving communication (RF, Bluetooth, etc.) and to play video data of portable storage device on small display screen. And outputting screen display data through data conversion and a video controller. In addition, it has a voice recording and mail transmission function that can be transmitted by attaching a stored voice file through a simple voice recording as an email attachment.

1 overall configuration

2 is the main configuration of the present invention

Figure 3 application of the present invention

Please refer to the attached drawings to further describe the above contents.

First of all, the overall configuration of FIG. 1 receives data through IO of the apparatus from IO of a mobile phone. At this time, the communication protocol between the mobile phone and the device follows the established USART communication protocol. In addition, more diverse and convenient services can be achieved through cooperation with telecommunication companies in order to utilize various application information. In addition, as MP3, which is widely used now, has a great effect on moving and reproducing voice data, it is expected that there will be great development in moving and reproducing video data in the future with the development of small and large mobile data storage devices. That is, it is possible to enjoy while carrying a music video at the level of listening to music through the data of the memory card 32 of FIG. Already, TV has more than one in the home, and portable TVs and car TVs are also increasingly used, so that various applications of the AV device 33 of FIG. 3 are possible. In this way, the transmission data for the utilization of various information can be output to the small TV and display device according to the control method of the device, and the existing limited display screen can be extended and applied, so that the information can be easily and conveniently used outdoors and in the vehicle. have.

Referring to the main configuration diagram of the inside of the device in detail in FIG. 2, the data transmitted from the mobile phone 6a, the portable storage device 4a, and the other 7a are processed by the wired / wireless IO process 21 to communicate with the communication module 22. ), The central processing unit communicates with the data format that can be recognized, and the central processing unit converts, stores, edits, and outputs a video signal suitable for the portable display device through the video controller. Video signal processing follows the regulations of Mpeg-4.

In the case of the wired / wireless IO process 21, the USB port, which is a popular input / output port, can be compatible with infrared communication, RF radio frequency communication, and Bluetooth. It can be used for various application devices by enabling portable video play.

The communication module unit 22 defines a protocol between these various communication devices, grasps the connection state of external devices, connects to the central processing unit 23, sets the data processing environment, and processes the data according to the prescribed processing when storing and transmitting the data. do.

The D / A converter 25 outputs an image signal for converting the input digital data into an analog signal or converting the format of the digital signal to the video controller 27 for screen control. If necessary, the digital signal may be image-processed without analog signal conversion.

In addition, a temporary data buffer is provided through the internal RAM 26 to smooth the connection of data communication and to help data processing of the central processing unit. In addition, the bus converter 24 allows smooth control and processing of internal communication for each component.

As shown in FIG. 3, the processed video signal is output by the video controller 27 to the small display device. The small display device 28 may be used as a single device including a display unit by using a small display device with the built-in device as shown in FIG. 3, or the display unit may process an image through a vehicle TV device using only the display unit as a separate device. Produced by dividing into external devices. In addition, the voice memory 35 stores a simple voice recording 34 data, and transmits a voice file when the mail is transmitted to perform a voice mail function.

As mentioned above, through the free use of voice and video data through this device, it overcomes the limitations of mobile communication using PDA and CDAMA by using various application devices and interconnecting with mobile phones that are strong in mobile and data communication. When using the chip-integrated multi-terminal device, it is possible to selectively use it according to the user's environment by eliminating the double burden of communication fee due to double use with the mobile phone.

In addition, the mobile phone is also provided with a variety of wireless interfaces, eliminating the communication constraints between the portable devices through the existing wired connection to make the most of the advantages of the mobile device at a minimum cost, which can be an important interface means in the information and communication era to be.
