Described control unit 15, for receiving first display picture data, second display picture data and institute
The directional information of source of sound is stated, and according to the directional information of the source of sound, to the associate device output first display picture or institute
State the second display picture.
In embodiments of the present invention, described control unit 15 can for micro-control unit ((Microcontroller Unit,
MCU), it is specifically used for receiving the direction of first display picture data, second display picture data and the source of sound
Information；When according to the Anisotropic information of the source of sound to the direction of source of sound be close to the direction of first camera 11, and
When the preceding display picture data exported to the associate device is the second display picture data, to first camera 11 and
Second camera 12 issues the first switching command, and the switching for carrying out first display picture data to the associate device is defeated
Out；When being and to work as close to the direction of the second camera 12 according to the Anisotropic information of the source of sound to the direction of source of sound
When the display picture data of the output of associate device described in forward direction is the first display picture data, to first camera 11 and institute
It states second camera 12 and issues the second switching command, and carry out the switching of second display picture data to the associate device
Output；First camera 11 is also used to receive first switching command, according to first switching command to the control
Unit 15 processed exports the first display picture of default first resolution；And second switching command is received, according to described second
Switching command exports the first display picture of default second resolution to described control unit 15；Wherein, the first resolution
Greater than the second resolution；The second camera 12 is also used to receive first switching command, cuts according to described first
Change the second display picture that instruction exports default second resolution to described control unit 15；And it receives second switching and refers to
It enables, exports the second display picture of default first resolution to described control unit 15 according to second switching command, need
Illustrate, the associate device, that is, another intelligent interaction plate including display screen switching Transmission system, two intelligence are handed over
Realize video conference function between mutual plate, described control unit 15 receives first display picture data and described the simultaneously
Two display picture datas, thus reach the rapid of the switching output of display picture data with conveniently, avoid not receiving simultaneously it is described
First display picture data and second display picture data cause to regard to cause switching output to need to wait switching time
Frequency picture is not connected, and influences the usage experience of user, and described control unit 15 receives the first display frame numbers at the same time
According to and when second display picture data, issue the first switching to first camera 11 and the second camera 12 and refer to
Order or the second switching command, so that the high resolution of the display picture data transmitted to the associate device is in another
Without the display picture data of transmission, to achieve the purpose that save bandwidth, such as when described control unit 15 is switched to institute
When stating associate device the first display picture data of transmission, described control unit 15 states the first camera 11 and described second to described
Camera 12 issues the first switching command, so that first camera 11 exports such as resolution ratio to described control unit 15
For the first display picture data of 1080p, the second camera 12 exports such as resolution ratio to described control unit 15 and is
The second display picture data of 360p, so that whole achieve the purpose that save bandwidth and display picture data easy switching.
In embodiments of the present invention, it should be noted that beginning to use the video meeting software on the Intelligent flat
When, the directional information of the sound source is transferred to by the source of sound scan process module 14 after getting the directional information of sound source
Described control unit 15, described control unit 15 are automatically opened after the directional information for receiving the sound source close to the sound source side
To camera carry out display picture data acquisition, handoff procedure is completed after 2~3 seconds, in order to avoid open simultaneously described first
Camera 11 and the second camera 12 cause maloperation phenomenon.
In conclusion first embodiment of the invention provides a kind of display screen switching Transmission system, by it is described at least
Two sonic detection modules 13 detect voice signal, judge source of sound belonging to the voice signal by the source of sound scanner
Directional information, control unit 15 realize the first display picture that first camera 11 acquires according to the directional information of the source of sound
The automatic switchover for the second display picture data that face data and the second camera 12 acquire, is realized to from sound source direction institute
Position display picture shooting, increase the output aspect ratio of speaker in video conference scene so that spokesman with
Attentive listener has a kind of effect linked up face-to-face, avoids influencing to regard due to the ratio because of spokesman shared by showing picture is less
The speech effect of frequency meeting, so that in the speech that the both sides of video conference can be absorbed in spokesman when spokesman makes a speech
Hold, improves the meeting efficiency of video conference.
In an alternative embodiment of the invention, the display screen switching Transmission system further includes third camera 16.
The third camera 16, for being connect with described control unit 15, for acquiring the within the scope of present viewing field
