Embodiment
Here will be described exemplary embodiment in detail, its sample table shows in the accompanying drawings.When description below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawing represents same or analogous key element.Embodiment described in following exemplary embodiment does not represent all embodiments consistent with the present invention.On the contrary, they only with as in appended claims describe in detail, the example of apparatus and method that aspects more of the present invention are consistent.
Fig. 1 is the process flow diagram of a kind of video session window control method according to an exemplary embodiment.The method can be used for the terminal device such as mobile phone, computer.Shown in Figure 1, the method can comprise:
In step S101, in many people video session, monitor the audio stream of each user.
In many people (or perhaps in many ways) video conference, each user (or perhaps meeting one side) usually can see multiple session window the terminal of oneself, the corresponding user of each session window.Such as, attend a meeting if certain video conference one has N number of user, the session window that so each user sees is N-1.Each session window is except video pictures, and also with audio frequency, namely the present embodiment is monitored the audio stream of each user.
In step s 102, according to the audio stream of described each user, determine the current user spoken.
Because the audio stream of the user spoken can be different with other users, so pass through the feature of the audio stream analyzing each user, can determine that current is which user speaks.When implementing, concrete analysis means the present embodiment is not limited.
In step s 103, dynamic conditioning is carried out to the video session window of described each user, to make the video session window of the described current user spoken highlighted.
To the object that the video session window of each user adjusts, or perhaps effect, be make the video session window of the current user spoken highlighted.Because user wants simultaneously in the face of multiple video session window in see video conference process, find immediately when there being sound to transmit current just talker be one comparatively difficulty thing, and in the present embodiment, the video window of the current user spoken can be highlighted, be easy to differentiate, thus work efficiency when improve many people video session, also improve Consumer's Experience.
How video session window as each user is dynamically adjusted, how highlighted the video session window of the current user spoken is, the present embodiment is without the need to limiting, and those skilled in the art can determine according to different scenes or interface demand.
Shown in Figure 2, in the present embodiment or the disclosure some other embodiments, the described audio stream according to described each user, determine the current user spoken, can comprise:
In step s 201, the sound size in the audio stream of described each user is detected.
In step S202, user maximum for current sound is defined as the current user spoken.
Or shown in Figure 3, in the present embodiment or the disclosure some other embodiments, the described audio stream according to described each user, determine the current user spoken, can comprise:
In step S301, add up the flow of the audio stream of described each user in preset time period.Such as add up the flow in nearest a minute.
In step s 302, user maximum for flow is defined as the current user spoken.

Amplified by the video session window of the described user spoken, position in advance;
The video session window of other users is reduced, after position is moved.
Exemplarily can see shown in Fig. 4 ~ Fig. 8:
In scene shown in Fig. 4, have A, B, C, D, E totally 5 users participate in many people video conference, the computer of user E can be seen video session window A, B, C, D of other 4 people, is 2 × 2 to be uniformly distributed when these 4 video session windows are initial.
By monitoring audio stream, can detect the sound of user C current be maximum, therefore user C can be defined as the current user made a speech, then window C is promoted to from the uniform distribution shown in Fig. 4 and highlights state shown in Fig. 5, be placed on the front end extrusion position of screen, other people window is then reduced accordingly, moves on to the rear of screen.Fig. 6 is then the form that another kind highlights, and window C is exaggerated and is placed in the central authorities of screen in figure 6, and other people window is then reduced and be placed in after window C.
In scene shown in Fig. 7, have A, B, C, D, E, F, G totally 7 users participate in many people video conference, the mobile phone of user G can be seen video session window A, B, C, D, E, F of other 6 people, is 3 × 2 to be uniformly distributed when these 6 video session windows are initial.
By monitoring audio stream, can detect within the time period of nearest one minute, the audio frequency flow of user D is maximum, therefore user D can be defined as the current user made a speech, then window D is promoted to from the uniform distribution shown in Fig. 7 and highlights state shown in Fig. 8, be placed on the front end extrusion position of screen, other people window is then reduced accordingly, moves on to the rear of screen.
In addition, shown in Figure 9, in the present embodiment or the disclosure some other embodiments, described method can also comprise:
In step S104, according to the change directive received, change the determined current user spoken.
This is because, consider that terminal device exists error in judgement when carrying out automatic decision sometimes, or user sometimes to want to specify certain window highlighted, so allow user to change the current user spoken.
Exemplarily can be shown in Figure 10, in Fig. 10, window D is highlighted originally, but user can use finger to drag, and is dragged to by window C and highlights position, and window D then will move on to the position of original window C accordingly automatically.
