The wireless communication system transmits the sound frequency to the second mobile phone of the destination. The video/audio mobile transmitter of the second mobile phone demodulates the sound frequency. It converts into the image data, and then display in the display apparatus of the second mobile phone.

Description

1239190 V. Description of the invention α) [Field of the invention] The present invention relates to a method and device for transmitting video of a digital mobile phone system, and more particularly to a method of transmitting [transmitting and receiving] an image using a sound channel of the digital mobile phone system. And its equipment. [Previous technology] ^ In addition to transmitting, capturing and playing back video, video transmission between traditional telephone line network video equipment (such as web video telephone, web video telephone) requires relay equipment. The video equipment or computer on the transmitting side transmits the captured image data stream to the transmitting regional headquarters. The transmitting regional headquarters receives the image data streaming and transmits it to the transmitting device ’s Internet Protocol (IP) channel device. And converted into a 0/1 digital stream, the digital stream is dispersed into a number of packets [data packets or message packets [packet]], the packet has the marked address, sorted, and transmitted through the dedicated line transmission network and Internet protocol channels. The IP path device enables the packet to reach its destination via different paths. The IP channel device at the destination restores the digital stream of the packet into an image data stream according to the address and sequence, and then transmits the digital stream to the head office of the receiving area, and the head office of the receiving area passes the image stream to the receiving video equipment. Or computer. Although image transmission via the Internet can reduce costs, even if the user's rate is lowered ', network traffic can greatly reduce the transmission quality. As for the image data transmission of traditional mobile phones (such as WAP mobile phones), wireless Internet access is used for image data transmission. In 1 9 9 7

At the same time, the transmission cost of wAp's wireless Internet service is too high and the service items are too few. Similarly, the video data transmission of mobile phones encountered the problem of network traffic. In addition, when the rights of video materials are too large, it is not easy to transfer them. At the same time, when the number of captured image files of the image manipulation device is insufficient, the image playback is prone to interruption. At present, GpRs services have been successively introduced by domestic Hexin, Chunghwa Telecom, and Yuanchuan. After that, the Big Brother University of Taiwan independently developed and launched the "Multi-Media Messaging Service (MMS) service transmitted by the system", ^ "Mobile Photo" Service that wirelessly transmits data such as text, music, and moving images. The MMS service can deliver color / kinetic patterns in JEPG or GIF format. The most important thing is that the MMS service of Taiwan's Big Brother is also limited to intranet ^ and it is still a wireless Internet service that requires Internet access. As for mobile phones, only Sony Ericsson T 68 i has MMS function. In other words, the MMS service object must be able to perform the 8-bit transmission service on a mobile phone with MMS function. Regardless of whether digital images are transmitted in the WAP or MMS state, there is a problem of compatibility ^ / compatibility. If the operating platform is not connected, the images cannot be mutually compatible ^
