Fig. 2 is that the internet that utilizes that prior art provides carries out the structural representation of the video call system of video calling;
Fig. 3 is the structural representation of the telephone set that provides of the utility model embodiment;
Fig. 4 is the structural representation of the video call system that provides of the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the utility model.
In the utility model embodiment, by increasing network access module, audio-video interface module and control module in the conventional telephone set, can carry out video calling by a telephone set, reduced hardware device compared to existing technology, cost is low, and the user only needs at the phone hands-operation, and is simple to operate.
Fig. 3 shows the structure of the telephone set that the utility model embodiment provides, and for convenience of explanation, only shows the part that the utility model embodiment is correlated with.This telephone set comprises: phone module 31, network access module 32, control module 33, audio-video interface module 34, camera 35, display module 36, earphone 37, microphone 38.
Network access module 32 is used to insert IP network, adopts the ADSL network access technique in the present embodiment, and network access module 32 is adsl equipments.
Audio-video interface module 34, it is the input/output interface of audio frequency and video, can give earphone 37 by output audio signal, video image and reception user that outputting video signal shows or receive that camera 35 is absorbed for display module 36 pass through the audio signal that microphone 38 is imported.
Wherein control module 33 comprises: the control unit 331 of shaking hands, call mode switch unit 332, and the control unit 331 of wherein shaking hands is used for finishing transmission, the parsing of handshaking information; Call mode switch unit 332 is used for finishing the switching of normal speech call mode and video calling pattern.In embodiments of the present invention, control module 33 is microprocessors.
The concrete course of work is as described below: calling party's user starts phone module 31 and carries out common voice call, when video calling is carried out in hope, calling party's user presses the corresponding button that starts video calling on the telephone set, after control module 33 receives this key information, control unit 331 sends the telephone set of handshake request information to the callee by shaking hands, and the response message that returns of the telephone set that receives the callee, it is resolved, obtain the other side's telephone set equipment information and current IP information, affirmation is shaken hands after the success, telephone set by call mode switch unit 332 control calling partys is set up being connected of IP based network with callee's telephone set by network access module 32, transmit the telephone set that vision signal is given the callee by IP network, after callee's telephone set receives vision signal, audio-video interface module 34 is under the control of control module 33, export described vision signal to display module 36 and show, by earphone 37 output voice signals.
