For making those skilled in the art more clearly understand the embodiment of the invention, at first introduce some professional knowledges that the embodiment of the invention relates to.
The embodiment of the invention mention based on the net true technology point-to-point video communication system be meant two clients based on the net true technology carry out the formed communication system of video communication.With Fig. 1 is example, establishes three communication links that are used to carry out video communication between client 1 and the client 2, comprises that a main communication link and two are from communication link.Provide the video source apparatus 22 of video source that vision signal is offered codec 21,21 pairs of video signal codings of codec and will encode by main communication link after vision signal offer codec 11,11 pairs of decoding video signals of receiving of codec, and decoded vision signal offered display screen 12, display screen 12 is according to the vision signal display video image of receiving.In like manner, video source apparatus 22 ' offers codec 21 ' with vision signal, codec 21 ' offers codec 11 ' to video signal coding and by the vision signal after will the encoding from communication link of correspondence, the decoding video signal of codec 11 ' to receiving, and decoded vision signal offered display screen 12 ', display screen 12 ' is according to the vision signal display video image of receiving.In like manner, video source apparatus 22 " vision signal is offered codec 21 ", codec 21 " offer codec 11 to video signal coding and by the vision signal after will the encoding of correspondence " from communication link, codec 11 " decoding video signal to receiving; and decoded vision signal offered display screen 12 ", display screen 12 " according to the vision signal display video image of receiving.Video source apparatus for example is the first-class camera head of shooting.
In actual applications, if main interrupted communication link, so all also will interrupt from communication link.If one from interrupted communication link, so main communication link is unaffected from communication link with other, still continues to transmit vision signal.
Client 1 can also comprise control equipment 13 in one, and middle control equipment 13 both can have been controlled three display screens, also can control three codecs.In control equipment 13 both can be by wired mode control display screen curtain and codec, also can be by wireless mode control display screen curtain and codec.Middle control equipment can be according to user who participates in video communication or technical staff's triggering control display screen curtain and codec.
In actual applications, middle control equipment 13 has multiple mode control display screen curtain.For example, the opening and closing of control display screen curtain, the display brightness of control display screen curtain, the size of control display interface etc.
In actual applications, middle control equipment 13 has multiple mode to control codec.For example, the codec of control codec and client 2 is set up communication link, is removed communication link etc.
The all embodiment of the present invention are applicable to the point-to-point video communication system based on the true technology of net, this communication system comprises two clients, each client comprises at least one codec, all corresponding communication link that is used for carrying out with the opposite end of video communication video communication of each codec.That is to say that the embodiment of the invention is not limited to and is applied in the network environment that client comprises three codecs, three display screens, three communication links.
The embodiment of the invention both can be described from the angle of codec, and the angle that can also therefrom control equipment is described.
At first introduce a kind of point-to-point video communication method that the embodiment of the invention provides based on the true technology of net from the angle of codec.As shown in Figure 2, this method comprises:
S201: codec is determined the interrupted communication link of described codec correspondence.
In actual applications, codec can be determined the interrupted communication link that it is corresponding in several ways.For example, can be set the time limit of receiving video signals in the codec, if codec was not received the vision signal that the codec of opposite end provides in this time limit, codec can be determined the interrupted communication link that it is corresponding so.Again for example, codec just sends detection signal to the codec of opposite end at set intervals, if codec is not received the response signal that the codec of opposite end returns at detection signal in the time limit that sets in advance, codec can be determined the interrupted communication link that it is corresponding so.Certainly, codec can also be determined the interrupted communication link that it is corresponding by other modes, illustrates no longer one by one here.
After codec was determined its corresponding interrupted communication link, codec can send the information of the interrupted communication link that is used to represent the codec correspondence to middle control equipment.That is to say that codec is after determining its corresponding interrupted communication link, control equipment in the information of interrupted communication link can being notified to is so that whether middle control equipment rebulids decisions such as communication link.
S202: described codec rebulids described communication link to the request of the opposite end of video communication.
Codec determines after its corresponding interrupted communication link that directly the codec request to the opposite end rebulids described communication link.That is to say, codec can the situation of the triggering of control equipment in not obtaining under, directly the codec request to the opposite end rebulids described communication link.In actual applications, codec can send the request message that rebulids described communication link and ask to rebulid described communication link by the codec to the opposite end, after codec sends request message, can receive the response message that the codec of opposite end sends.
If codec is determined after its corresponding interrupted communication link, sent the information of the interrupted communication link that is used to represent the codec correspondence to middle control equipment, codec can be in receiving after the triggering of control equipment so, and the codec request to the opposite end rebulids described communication link again.Concrete, the triggering that rebulids described communication link that control equipment sent during codec obtained, codec rebulids described communication link according to described triggering to the request of the opposite end of video communication.In actual applications, the triggering that rebulids communication link of sending of middle control equipment can be the message that is used to represent to rebulid described communication link that middle control equipment sends.
In actual applications, when codec when the codec request of opposite end rebulids communication link, the opposite end may be provided with interruption-free, that is to say, the too much request of setting up communication link is not wished to receive in the opposite end, and in this case, the codec only codec to the opposite end sends the request that once rebulids communication link, no matter link establishment success or not does not send the request that rebulids communication link once more.Concrete, codec determined that the opposite end was provided with interruption-free before the codec request of opposite end rebulids described communication link, codec only sends the request that once rebulids communication link to the codec of opposite end.In actual applications, codec can provide by the codec that obtains the opposite end is used to represent that the opposite end is provided with the information of interruption-free, determines that the opposite end is provided with interruption-free.
In actual applications, may rebulid the situation of communication link failure.To this, at codec after the codec request of opposite end rebulids communication link, if rebulid the communication link failure, codec can send to the display screen of correspondence and be used to represent the information that rebulids the information of communication link failure and be used to represent rebulid the reason of communication link failure so, and display screen can show these information.
If rebulid communication link failure, so codec once more the codec request to the opposite end rebulid communication link, if still failure can ask to rebulid communication link so once more, until rebuliding the communication link success.
In actual applications, if codec connects a loud speaker, when the codec request to the opposite end rebulids communication link, can not send triggering signal so to loud speaker, in order to avoid loud speaker sends the sound that rebulids communication link, avoid bothering the user who carries out video communication.
Corresponding above-mentioned method embodiment, the embodiment of the invention also provides a kind of codec, and as shown in Figure 3, this codec comprises: interrupt determining unit 301, be used for determining the interrupted communication link of described codec correspondence; Link establishment unit 302 is used for rebuliding described communication link to the request of the opposite end of video communication.
Codec can also comprise interruption-free determining unit 303, is used in link establishment unit 302 determining that the opposite end of video communication was provided with interruption-free before the request of the opposite end of video communication rebulids described communication link.If interruption-free determining unit 303 determines that the opposite end of video communication is provided with interruption-free, then the link establishment unit specifically is used for only sending the request that once rebulids described communication link to the opposite end of video communication.
Codec can also comprise information transmitting unit 304, rebulid the communication link failure if be used for the opposite end of link establishment unit 302 and video communication, then send and be used to represent the information that rebulids the information of communication link failure and be used to represent rebulid the reason of communication link failure to the display screen of codec correspondence.
In link establishment unit 302 after the request of the opposite end of video communication rebulids described communication link, if link establishment unit 302 rebulids the communication link failure with the opposite end of video communication, then link establishment unit 302 specifically is used for rebuliding described communication link to the request of the opposite end of video communication once more, until rebuliding the communication link success.
