Implementing method and equipment for picturphone based on multiple transmission medium cooperative working

Abstract

This invention provides a visual phone device and a method based on cooperation of multiple kinds of transmission media, in which, the device includes: an off-hook test unit, a number-collecting unit, a CPU, an audio input-output interface and a video terminal output interface, in which, the off-hook unit is used in testing if the call via the audio input-output interface is on-line, said collecting unit is used in reading calling or called number via the audio input-output interface, said CPU is used in receiving test information of the off-hook test unit and calling or called number information of the number-collecting unit to be transmitted to the video terminal via the video terminal ouput interface.

Description

technical field [0001] The present invention relates to real-time communication and multimedia communication technology involving multiple transmission media, in particular to a method and equipment for realizing videophone which is completed through cooperation of IP network and ordinary telephone network. Background technique [0002] As an indispensable communication tool in people's daily life and work, the telephone is widely used with its convenience and speed, but the common telephone can only be "only hear its voice, not see its person". With the progress of the times and the improvement of people's living standards, it has become the dream of many people to hope to see the other party's voice and smile while talking. A videophone system, sometimes called a videophone system, refers to individuals or groups in two different places, through the videophone system, the audio and video are transmitted to each other to achieve instant and interactive communication. The v...

Problems solved by technology

The disadvantage of the pure software method is that it is complicated to use and does not match people's traditional habit of making phone calls. It relies heavily on the computer and cannot even provide audio services when the computer is turned off. At the same time, it cannot fundamentally guarantee basic audio services. quality

The pure hardware method needs to configure an independent videophone terminal to process images and sounds. Such terminal equipment is often complex in structure, high in cost, and expensive. At the same time, it cannot guarantee the quality of service at a relatively low price.

[0006] All in all, the above-mentioned traditional videophones are all committed to simultaneously transmitting audio information and video information on a transmission medium (or on the public telephone switching network, or on the IP network), but the current technology and application environment cannot fully Guarantee the quality of service of simultaneous real-time transmission of audio and video on the same transmission medium
