But audio-video frequency content can only be listened to and watch to common TV set-top box at present.In addition, can not local sound and image send to far-end or be transported on television image, be exactly in other words that current Set Top Box does not possess interaction capability.
Summary of the invention
For solving TV set-top box in prior art, there is no interaction effect, with the problem of the television set selling at exorbitant prices of interaction effect, the utility model provides a kind of interactive Intelligent set top box.
For achieving the above object, the scheme that the utility model adopts is: a kind of interactive Intelligent set top box, comprise Set Top Box and support, described Set Top Box comprises shell, audio interface, network interface, power interface, HDMI interface, USB interface, infrared interface, display floater, mains switch, control chip, internal memory and flash memory.
Described Set Top Box is separately provided with audio processing chip, loudspeaker, microphone and camera; Described microphone, loudspeaker are connected with audio processing chip, and audio processing chip is connected with control chip; Described camera is connected with control chip.
Described support comprises holding section and connecting portion.Described holding section side is provided with the clamp to downward-extension, and top is provided with the sphere pit to lower recess, and another side and connecting portion are connected through the hinge; Described outer casing bottom is provided with the spherical surface hill that the sphere pit that is provided with support holding section matches; The sphere pit at top, described holding section is flexibly connected with the spherical surface hill of support sector bottom.
Further, the spherical surface hill movable connection method of the sphere pit at top, described holding section and support sector bottom is that magnet is fixed or screw is fixed.
Further, described hinge connection is provided with locking device.
Further, the madial wall of the clamp of holding section inner side and connecting portion is provided with silicagel pad.
Further, described loudspeaker are two; Described microphone is two.
Further, described camera is the 5000000 pixels high-definition cameras of automatically focusing.
Further, described audio processing chip is DSP audio processing chip.
Adopt after the technical program, in Set Top Box, be equipped with microphone and camera, local sound and image can be input to control chip, control chip is to obtaining sound and image information, do respective handling, then provide corresponding output, thereby realize the interaction between user and television set or remote subscriber.Solve the problem that in prior art, common machine top box cannot be interactive, expanded range of application and the space of Set Top Box.

Embodiment
Below in conjunction with accompanying drawing, the preferred scheme of the utility model is further described:
As shown in Figure 1, a kind of interactive Intelligent set top box, comprise Set Top Box 1 and support 2, described Set Top Box 1 comprises shell, audio interface, network interface, power interface, HDMI interface, USB interface, infrared interface, display floater, mains switch, control chip, internal memory and flash memory.
As Fig. 4, shown in Fig. 5, described Set Top Box 1 is separately provided with audio processing chip 15, and audio processing chip 15 is DSP audio processing chip.14, two microphones 11 of two loudspeaker and camera 12; Microphone 12, loudspeaker 14 are connected with audio processing chip 15, and audio processing chip 14 is connected with control chip; Camera 12 is connected with control chip.Camera 12 is the 5000000 pixels high-definition cameras of automatically focusing.
As shown in Figure 2, described support 2 comprises holding section 21 and connecting portion 22.Described holding section 21 sides are provided with the clamp 211 to downward-extension, and clamp 211 inner sides are provided with silicagel pad 213.Top is provided with the sphere pit 212 to lower recess, and another side and connecting portion 22 are connected through the hinge, and hinge connection is provided with locking device 23.The madial wall of connecting portion 22 is provided with silicagel pad 221.Described Set Top Box 2 bottoms are provided with the spherical surface hill 13 that the sphere pit 212 that is provided with support holding section 21 matches.
As shown in Figure 1, the spherical surface hill 13 of sphere pit 212Yu support sector 21 bottoms at 21 tops, described holding section is flexibly connected.
As shown in Figure 3, preferred, the sphere pit 212 at 21 tops, holding section is by easily being made by the material of magnet adsorption, with spherical surface hill 13 movable connection methods of Set Top Box 1 bottom be that magnet 131 is fixing, magnet 131 is placed on the inside of spherical surface hill 13.
The audio processing chip 15 that this programme adopts is DSP audio processing chips, at chip internal, after processing by low noise amplifier, low pass filter and dynamic gain control, eliminated high-frequency signal, this noise reduction system has effectively been eliminated line noise, nonlinear noise and high-frequency signal, chip can be adjusted according to phonetic feature the parameter of denoising algorithm and amplification, thereby as much as possible extracts effective voice signal.
Meanwhile, adopt the microphone 11 of 2 high sensitivity arrays, in conjunction with DSP audio processing chip, improved the dynamic range of microphone 11.Meanwhile, utilize dual microphone 11, can realize the angle Selection to voice source, strengthen positive next speech volume, suppress the noise volume of coming in side.
In addition, the audio-frequency information sending for far-end, by the integrated loudspeaker of the machine, by its audio-frequency information, the microphone 11 by the machine returns after DSP audio processing chip is processed and forms echo.After DSP audio processing chip is processed, cut known echo composition, thereby only local user's voice are sent, realized the function of the echo that disappears.
This programme adopts the 5000000 pixels high-definition camera of automatically focusing in addition, and image clearly can be provided, and contributes to far-end to see local scene clearly.
In sum, in Set Top Box 1, be equipped with microphone 11 and camera 12, audio frequency and the image of local and far-end can be input to control chip, control chip is to obtaining audio frequency and image information, do respective handling, then provide corresponding output, thereby realize the interaction of user and television set or remote subscriber.
Above scheme is only the preferred scheme of the utility model, so long as those of ordinary skill in the art's technology novel according to this just can not realize through creative work, within all dropping into originally novel protection range.
