Embodiment Construction

[0050] The existing VoIP device converts the analog voice signal into a voice packet that can be transmitted through the data network through the switch, and transmits it to the receiving end. Both communication parties must have a VoIP phone with a built-in VoIP device function. First, set the IP address and other necessary settings. After the settings are completed, they can communicate. The most important thing about this VoIP device is to achieve real-time phone calls. The purpose of saving telephone bills.

[0051] Such as image 3The schematic diagram of the embodiment of the present invention is shown. In this embodiment, a relay server 123 connected to the Internet 52 is set as a transfer server between the local end and the destination device, which includes the transfer of the destination end from the local end through the Internet. Telephone lookup table (lookup table) function.

[0052] There can be a plurality of local end phones 12a, 12b, 12c in the local end, ...

Abstract

The invention discloses a transmission system and method of mobile image and sound data, which is characterized by the following: utilizing mobile image and sound data switching device transmitted on the IP packing bag through digital signal within a signal switching mode; making computer with transmitting end or receiving end transmit data through relay server of on-line internet; setting end telephone or computer checking function with switching goal in the relay server; transmitting data to terminal computer through checking function of internet; or transmitting the data to mobile communication equipment through relay server checking function of telephone network by mobile image and sound data switching device.

Description

technical field [0001] The invention relates to a mobile audio-visual data transmission method, in which a mobile audio-visual data conversion device is connected to an indoor telephone device and coupled to a relay server connected to the network to realize the purpose of audio-visual data transmission and real-time communication. Background technique [0002] VoIP (Voice over IP) is a voice service that compresses voice signals into data packets and transmits them on the basis of the Internet Protocol, that is to say, it is a telecommunication application service that transmits voice through the open Internet. The use of the Internet not only provides voice services in real time, but also connects to all parts of the world, so that users no longer need to conduct long-distance telephone conversations through the traditional public telephone network (PSTN). [0003] VoIP is the real-time transmission of the original analog (analog) sound signal on the Internet Protocol Data...
