Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of method and system that when recording the other side's image, provide information.
Background technology
Visual telephone service is a kind of multimedia communication service that integrates image, voice, can realize the aspectant instant communication of people, and promptly both call sides can be seen the other side's scene mutually in communication process.Video telephone can realize that the visual telephone service that in the WCDMA network, requires at present is meant based on circuit domain (CS) and carries the visual telephone service of realizing through packet mode or circuit mode.
Exhale object and by being exhaled object can be divided into following several kinds again according to the beginning:
Calling between the portable terminal: the beginning, the side of exhaling all was a portable terminal with called party, followed H.324 agreement.
Calling between portable terminal and the video gateway: portable terminal promptly can be decided to cry and also can be done calledly, follows H.324 agreement, and the portable terminal beginning exhales square tube often need support two-stage dialing.
The operator that also has in addition provides video-mail professional, and portable terminal can be dialed the content that the video-mail platform obtains video-mail.
The relation of medium, control signal, call treatment, each layer protocol such as multiplexed is as shown in Figure 1.When video telephone was initiated, at first both sides set up the physical channel through calling procedure, were the mutual of control signal (H.245) then, sent data side through after cutting (CCSRL), dividing preface (NSRP), through multiplexing (H.223), sent the other side to via physical layer.The recipient collects (NSRP), combination (CCSRL) in order, passes through the mutual of control signal, accomplishes the foundation of the passage of video telephone.At this moment both sides' video/audio signal just can pass through media codec and the other side and carries out visual mutual.
Video telephone is that 3G operator widelys popularize as embodying 3G network, the especially business of WCDMA network characteristics always, also is a kind of video traffic that the user enjoys a lot.
But everybody enjoy partner visual in, on the one hand contradiction also embodies in addition, is exactly the problem of individual privacy, so provide quiet at a lot of terminals, and sends the privacy that means such as substituting picture are protected the user.
But also have a kind of situation to need to consider.Present radio phone terminal mostly provides the function that the other side's image is recorded, and so just might under the unwitting situation of user, be recorded a video by the other side, thereby has caused the own right of privacy to be invaded.Therefore prevent that the user from being recorded the video telephone image and extremely being necessary under own unwitting situation.
Summary of the invention
In order to solve above-mentioned technical problem, a kind of method and system that when recording the other side's image, provide information are provided, its purpose is, prevents that the user from being recorded video telephone under unwitting situation.
The invention provides a kind of method that when recording the other side's image, provides information, may further comprise the steps:
Step 1 is recorded direction and is sent by the side of recording and record prompting, and sends the recording request order;
Step 2 is recorded the prompting of recording that the direction user shows that the side of recording provides;
Whether step 3 if the quilt terminal of the side of recording supports signaling to resolve, then parses the recording request order, and recorded the answer of the direction side of recording and agree to record; If do not supported signaling to resolve by the terminal of the side of recording, if recorded,,, then ignored and record prompting by the side of recording if agreed to record by the side of recording then by the side's of recording finished call by the side's of recording refusal, continue conversation.
In the said step 1, receive the incident of recording notice after, the video I/O control module of the side of recording is stored in the N frame after local this incident of video file replacement with use, in said N frame, inserts to record prompting and order with recording request.
Said recording request order exists sign and recording request message for the implicit signaling code that the continuous N1 frame in said N frame inserts.
In the said step 3, the implicit signaling code existence sign of every two field picture is detected, have recording request message, then resolve in case detect by the side of recording.
In the said step 3, after detecting recording request message, eject to record and point out inquiry whether to be allowed the side of recording by the side of recording; Recorded acknowledgement command by the side of recording according to recording the prompting transmission.
Also comprise step 4, the side of recording resolves to reply and records acknowledgement command, begins to record, continues to record or abandon recording according to the content of recording acknowledgement command.
In the step 4, in continuous N1 frame, comprised that to the acknowledgement command of recording that the side of recording sends there is sign in implicit signaling code and records response message by the side of recording.
In the step 3; Implying signaling code when existing sign to detect, if the implicit signaling code in each frame exist sign F (xb, yb) with sequence of pixel values En in the sum of same pixel point greater than threshold xi 5; Think that then implicit signaling code exists sign effectively, begins to resolve recording request message; Otherwise this frame is normal picture frame.
In the step 3, when resolving recording request message, if (xa, ya) identical with the pixel of sequence of pixel values An sum are greater than threshold xi 5, and then this message is recording request message for sequence of pixel values F; Otherwise the recording request message in this frame is invalid, abandons.
In the step 4, when response message is recorded in parsing, if sequence of pixel values F (xa, ya) with sequence of pixel values Bn in the sum of same pixel point greater than threshold xi 5, then this message is for recording response message; Otherwise the response message in this frame is invalid, abandons.
In the step 4, if this message be response message: sequence of pixel values F (xa, if ya) with sequence of pixel values Cn in the sum of same pixel point greater than threshold xi 5, then this message is recorded response message for agreement; Sequence of pixel values F (xa, if ya) with sequence of pixel values Dn in the sum of same pixel point greater than threshold xi 5, then this message is for refusing to record response message.
The order that sequence of pixel values An, Bn, Cn, Dn and En fill pixel is identical with implicit signaling code parsing order; | Xn-Xn-1| >=2 ξ 1, n=0...N-1, Xn are An, Bn, Cn, Dn or En; | An-Bn| >=2 ξ 1, | Cn-Dn| >=2 ξ 1, n=0...N-1.

Embodiment
And the present invention is primarily aimed at is the calling between the portable terminal.
In this programme, send the other side's video frame image and sonagram picture frame to through replacement, and in image, comprise the method for hidden command sign indicating number, notify the other side to be about to carry out video telephone and record, can effectively protect user's privacy.For the mobile phone of not supporting this programme, can be seen that equally prompting pattern and prompt tone learn the other side's the behavior of recording thereby record the user, thereby determine whether to stop the other side's the behavior of recording through on-hook.If both sides' mobile phone is all supported this programme; Then recorded and can record with refusal, and will refuse to order the image concealing command code through this programme regulation to send the side's of recording mobile phone to, the side's of recording mobile phone can not carry out recording function; And providing similar prompting " because by the side of recording refusal; you can not carry out recording function " to the side of recording, the recording request by the other side has promptly refused in the side of recording has guaranteed the continuation of video telephone again.Application should mechanism after, visual telephone service will be more prone to received by the user, for operator's promotion business with improve user experience great promotion all arranged.
The object of the present invention is to provide a kind ofly in calling course of video telephone, when a side records the opposing party's video telephone, must send the implementation method of information to the other side.Can guarantee to be learnt the behavior of recording of the side of recording through this scheme, thereby the side of recording only could accomplish and records under by the situation of the side of recording permission by the side of recording.The application of this scheme, strong protection user's privacy, help the popularization of operator to visual telephone service.And this programme only need be changed the software at terminal, and without any need for the cooperation of network side.
When a kind of wireless terminal of the present invention was initiated visual telephone service, when the terminal use wanted to record the other side's video telephone image and sound, the solution that provides information to the other side comprised following part:
Video, audio input/output device: video input-output equipment is exactly camera and LCD for portable terminal, and the audio frequency input and output device is exactly Mike and receiver.

The underlying protocol module: support the protocol layer of video telephone, this part does not do any change in the present invention, does not relate to this aspect.
Above-mentioned visual telephone service terminal structure sees accompanying drawing 2 for details.
Technical scheme of the present invention is following:
When wireless terminal was initiated visual telephone service, when the terminal use wanted to record the other side's video telephone image and sound, the solution that provides prompting to the other side may further comprise the steps:
Step 1: the structure of video, audio prompt frame
The video that makes up, the effect of audio prompt frame are to be used for replacing video and the audio stream from camera and Mike that sends to the other side, thereby provide " the other side records prompting " on video telephone picture and the sound to the quilt side of recording.This section video, the time span of audio stream, suggestion content, the image size, each terminal can make according to the actual conditions at terminal.
Step 2: the making and the parsing of implicit signaling
In the image that sends, the signaling of recording request is lain in the pixel of image, thereby make the terminal of supporting this decoding, can parse this signaling.
In order to reduce because the channel error code in the transmission course, and the losing and misinformate of the implicit signaling that produces, then must be in continuous N frame the implicit signaling of re-transmitted, and come correct parsing to imply signaling through algorithm, specific algorithm will be described below.
The signal of camera output at present is yuv format basically.When judging the value of pixel, for Y wherein, U, three components of V can only select one of them component as criterion, also can select wherein two or all as the criterion of pixel value.And normally important selection of luminance component Y.
We use F, and (x y) representes each pixel (x, y) value in every frame.
According to standard definition
Y＝0.299R+0.587G+0.114B
U＝-0.147R-0.289G+0.436B
V＝0.615R-0.515G-0.100B
Be output as the processing of rgb format for camera, can convert yuv format to according to top formula and handle.
The principle of implicit signaling is that the position of in image, stipulating is inserted the pixel of a series of values of defining and represented a numerical value.Why; Select a sequence of pixel values; Rather than a pixel representes a message values, be for fear of when the pixel of image in the zone of the additional implicit signaling of picture frame itself is too small with the pixel sequence aberration of definition, and the misunderstanding that causes implying signaling analysed.For the value of sequence number n, can determine according to the difference of image yuv format.The n value of recommending is the even number value between the 4-12.Certainly adopting odd number value also not have can not.
We construct the following sequence with different pixel values:
An＝F(xn，yn)，n＝0...N-1
Bn＝F(xn，yn)，n＝0...N-1
Cn＝F(xn，yn)，n＝0...N-1
Dn＝F(xn，yn)，n＝0...N-1
En＝F(xn，yn)，n＝0...N-1
Wherein n is the sequence number.
To the signaling of recording process, mainly contain two:
VideoCallRecordRequest；
VideoCallRecordAck。
Signaling is made up of two following parts:
| Type of message |
| Message body |
The value of certain type of message in the implicit signaling, (xa, ya), a=0...N-1 representes to use sequence of pixel values F.The value of certain message body in the implicit signaling, (xb, yb), b=0...N-1 representes to use sequence of pixel values F.
The value of message types of VideoCallRecordRequest uses sequence of pixel values An to replace, and this message does not have message body.VideoCallRecordAck then comprises type of message and message body two parts.And corresponding two return values of message body, " agreement is recorded " and " refusal is recorded " can be used three sequence of pixel values Bn, and Cn and Dn replace.
Need an implicit signaling code of sequence of pixel values representative to have sign in addition, be used for indicating present frame whether to have implicit signaling code, (xc, yc), c=0...N-1 representes to use F.If present frame comprises signaling code, then use sequence of pixel values value En to replace.
An, Bn, Cn, the value of Dn and En is under the situation of not conflicting in the position, can value identical.
For pixel (x; Y) selection; Influence to reduce conversation on video telephone picture quality as far as possible is a prerequisite, exists sign and implicit signaling code can distribute the pixels with different zone for implicit signaling code, and has the sequence of pixel values of sign and implicit signaling code for implicit signaling code; Can arrange continuously according to certain shape in the position that provides, shown in Fig. 3 A to Fig. 3 E.Fig. 3 A to Fig. 3 E has just provided a kind of explanation, and concrete application can flexible customization.The identification of algorithm for ease can be that reference coordinate is selected with the coordinate at four angles.
Set pixel difference threshold values ξ 1, ξ 2 and ξ 3, the Y of difference corresponding pixel points, three components of U and V.This threshold values shows that color distortion is just thought identical pixel between two pixels in certain scope.
Set second pixel difference number threshold values ξ 5, n/2＜ξ 5＜n.Here n is the sequence number.
Below we (x, the Y value in y) is an example for references object, and analytical algorithm is described only to select F.
At first after video telephone was connected, the terminal began to keep watch on each two field picture, and there is sign F in the implicit signaling code of each two field picture, and (xb, Yb), b=0...N-1 judges.
If (x y)==1, thinks that these two pixels are identical, then C=C+1 (the C initial value is 0) to β.
Behind relatively intact more all pixels,, think that then implicit signaling code exists sign effectively, begins to resolve signaling if judge C＞=ξ 5.Otherwise this frame is normal picture frame.
Following for the signaling analytical algorithm:
At first judge the type of message that receives implicit signaling:
At first the sequence of pixel values An with the VideoCallRecordRequest type of message compares:
If β (x, y)==1, C=C+1 (the C initial value is 0) then
Behind relatively intact more all pixels,, explain that then this message is VideoCallRecordRequest message if judge C＞=ξ 5.
If judge it is not VideoCallRecordRequest message, then need continue to compare with the sequence of pixel values Bn of VideoCallRecordAck type of message:
If β (x, y)==1, C=C+1 (the C initial value is 0) then
Behind relatively intact more all pixels,, explain that then this message is VideoCallRecordAck message if judge C＞=ξ 5.
If, promptly be not VideoCallRecordRequest message through judging, neither VideoCallRecordAck message, then the implicit signaling of this frame is invalid, abandons.
If be judged as VideoCallRecordAck message, then message body content is judged that sequence of pixel values Cn and the Dn with representative " agreement is recorded " and " refusal is recorded " compares respectively:
If β (x, y)==1, C=C+1 (the C initial value is 0) then
Behind relatively intact more all pixels,, explain that then the message body content of VideoCallRecordAck is " agreement is recorded " if judge C＞=ξ 5.Otherwise continue relatively
If β (x, y)==1, C=C+1 (the C initial value is 0) then
Behind relatively intact more all pixels,, explain that then the message body content of VideoCallRecordAck is " refusal is recorded " if judge C＞=ξ 5.
If message body content promptly is not " agreement is recorded ", neither " refuse to record ", then the implicit signaling message that comprises of this frame is invalid, abandons.
In the said method, insertion, the parsing of implicit signaling code, insertion, the parsing of implicit signaling abandon implicit signaling code and detect later N-1 frame all by video, the completion of audio frequency I/O control module.
Several points for attention of this method:
1. must guarantee in the picture frame according to sequence of pixel values An, Bn, Cn, the order that Dn and En (there is sign in implicit signaling code for information representing type respectively, message body) fill pixel is identical with the order of signaling code parsing.
2. the correctness in order to guarantee to resolve, for satisfying following condition with the pixel value element in the sequence: | Xn-Xn-1| >=2 ξ 1, n=0...N-1, Xn represents An, Bn, Cn, Dn and En.
3. and for the sequential value of same nature, like An and Bn (type of message), Cn and Dn (message body), must satisfy following condition: | An-Bn| >=2 ξ 1, | Cn-Dn| >=2 ξ 1, n=0...N-1.
4. if only consider two message of present VideoCallRecordRequest and VideoCallRecordAck; Can not consider the difference of message body and type of message; Can reduce sequence of definition like this; But the expansion that consideration possibly exist is so defined type of message and message body.If adopt the way of not distinguishing message body and type of message, still be included in this claim.
Step 3: user's operating process
At first the video telephone both sides are in on-state.
Recording square tube crosses menu and selects to record the other side's video telephone image.
After receiving the incident of recording notice; Video, audio frequency I/O control is stored in local video and audio file with use, and (theming as prompting is recorded user the other side and will begin to record; If do not supported the parsing of implicit signaling like this by recording terminal; The user can obtain picture cues), replace the N frame after this incident.Consider the sensation of the user's vision and the sense of hearing, the suggestion time span of prompting image is greatly about 2-3 about second, if the broadcast frame number of per second at 10 frames, the frame number that then inserts is at the 20-30 frame.In these frames, select continuous N1 frame to insert implicit signaling code and have sign and VideoCallRecordRequest message.Because the insertion of N1 frame is arranged, so can guarantee the other side's reliable reception.
By the side of recording the implicit signaling code existence sign of every two field picture is detected, exist, then resolve in case detected implicit signaling.After detecting to VideoCallRecordRequest message, eject prompting frame, whether the inquiry user allows the side of recording.Annotate:, imply signaling in the N1 frame so the recipient need abandon the N1-1 frame of back because implicit signaling is sent continuously.
Recorded the direction side of recording and send VideoCallRecordAck message, if the user agrees to record, then message body is " agreement is recorded ", otherwise is " refusal is recorded ".Also in the N1 frame, sending to the side of recording should implicit signaling.
After the side of recording parses VideoCallRecordAck, ignore the implicit signaling of N1-1 frame of back equally, and accomplish the parsing of message body.If agreed to record by the side of recording, then begin video recording.Otherwise the ejection prompting frame, prompting the other side forbids video recording.2-3 is after second, and pop-up box disappears.Video telephone continues.
Below in conjunction with accompanying drawing, the present invention is done further detailed description.
When the invention provides a kind of wireless terminal and initiating visual telephone service, when the terminal use wants to record the other side's video telephone image and sound, provide the solution of information to the other side.This programme is reminded through sending prompting video to the quilt side of recording; And the dual mode that in images, adds implicit signaling; Guaranteed the quilt right of privacy of the side of recording in the calling course of video telephone, improved user experience greatly, helped operator and promote visual telephone service.
Step 1: user A calling party B, successfully set up conversation on video telephone.
Step 2: when the side of recording need record the other side's image, select to record the other side's image through custom menu.The user triggers the video telephony applications administration module through UI (user interface), sends " beginning to record " incident to video, the audio frequency I/O control module of bottom.After receiving " beginning to record " incident, control module begins to cut off video, the audio frequency input from camera and Mike, uses to be stored in local video and audio file replacement N frame (for example N=6 frame) image and sound after this.
In this N two field picture; (0＜N1≤N) (for example N1=3 frame) frame adds implicit signaling code existence sign and VideoCallRecordRequest message to the N1 of selection front, and the different band of position pixel of selection image adds both corresponding En and An pixel sequences.For implicit signaling code exist sign F (xc, yc)=Ec, c=0 ... N-1 (for example n=5 gets 5 pixels).For the VideoCallRecordRequest request message, and F (xa, ya)=Aa, a=0 ... N-1.
Through this step, even the parsing of implicit signaling is not supported at quilt terminal, the side of recording, can obtain the prompting on video and the audio frequency too, if the shortcoming of existence does not hope that the side of recording at video telephone exactly, then must hang up video telephone.After the replacement of having accomplished the N two field picture is sent; Video, audio frequency I/O control module will be exported and switch back camera and Mike again; And send notification event to application management module; Consider by the side of recording and receive the time-delay of recording the information image, record after notified and can after S second (for example S=3 second), begin to record considering.
Step 3: the terminal will detect whether there is implicit signaling to each frame that receives.When the user detects implicit signaling code and exists sign effective, then continue to resolve type of message.About the parsing of type of message description referring to top analytical algorithm.When detecting when being the VideoCallRecordRequest request message, then provide prompting frame to the user, the suggestion content meaning is " whether allowing the other side to record conversation on video telephone ".The user can select " being ".It should be noted that; Receive signaling message reliably in order to guarantee to be recorded to reach; In the side's of recording N continuous 1 frame, will repeat to send this message; When being received by the side of recording, must abandon the unnecessary message that repeats to send, simple way is no longer to resolve implicit signaling at the N1-1 frame that parses after this message of success.For fear of losing of implicit signaling, transmit leg should guarantee that two different implicit signalings are sent at interval, should be greater than 2 times N1 frame.
Step 4: according to the reflection of user to " whether allowing the other side to record conversation on video telephone " pop-up box; In the N1 two field picture after the user provides selection, will in sending the image of the side of recording to, be added type of message and message body that implicit signaling code exists sign and VideoCallRecordAck by the side of recording; Select the different band of position pixel of image to add the corresponding En of above-mentioned three; Bn, Cn (agreement is recorded), Dn (refusal is recorded) pixel sequence.For implicit signaling code exist sign F (xc, yc)=Ec, c=0 ... N-1.For the VideoCallRecordAck type of message, and F (xb, yb)=Bb, b=0 ... N-1.If the user selects " agreement is recorded ", VideoCallRecordAck message body be F (xc, yc)=Cc, c=0 ... N-1.If the user selects " refusal is recorded ", VideoCallRecordAck message body be F (xd, yd)=Dd, d=0 ... N-1.
Step 5: the side of recording sends to by the S behind the side's of recording prompting picture frame in completion and after second, no matter whether receive implicit signaling VideoCallRecordAck message, all will begin to record, and is former because recorded the parsing that can not support implicit signaling.After the side of recording detects implicit signaling code existence sign; VideoCallRecordAck message to receiving is resolved; If VideoCallRecordAck message body is " agreement is recorded ",, then continue the work of recording if this moment, the side of recording began to record; If also do not begin to record, then start the work of recording at once.If VideoCallRecordAck message body is " refusal is recorded ", if the side of recording has begun to record, then the terminal stops to record, the automatic file recorded of deletion, and eject prompting frame, prompting addressee refuses recording operation to the user.If the side of recording does not also begin to record, then directly eject prompting frame, prompting addressee refuses recording operation, and the follow-up recording operation that do not carry out.
Do not support to decode when implying signaling at quilt terminal, the side of recording; In the above-mentioned steps 2; Even do not supported the parsing of implicit signaling by terminal, the side of recording; The prompting on video and the audio frequency can be obtained too,, then video telephone must be hung up if the shortcoming of existence does not hope that the side of recording at video telephone exactly.
Those skilled in the art can also carry out various modifications to above content under the condition that does not break away from the definite the spirit and scope of the present invention of claims.Therefore scope of the present invention is not limited in above explanation, but confirm by the scope of claims.
