Abstract
The utility model provides a projector capable of carrying out video conferences, and relates to the field of projectors and video conferencing system products, in particular to a projector capable of carrying out video conferences. The projector mainly comprises a projector display terminal and a video conference terminal connected with a network. The projector is composed of an electronic circuit and an optical component. The optical component includes a light source, a lens and a digital micro-reflector. The electronic circuit is formed by a network drive, a video conference terminal processor, an audio encoder-decoder, a projector processor, a D-A/A-D converter, an electronic ballast and a loudspeaker, which are sequentially connected. During a remote video conference, the projector is capable of displaying video information without being connected with external display devices. The projector integrates receiving, processing and displaying of multimedia information, and facilitates users in use.
Description
Technical field
The utility model relates to projector and video conferencing system product scope, particularly a kind of projector that carries out video conference.
Background technology
Video conferencing system is the virtual meeting that realizes by the network communications technology, make geographically the user that disperses can copolymerization one place, by multiple mode exchange of information such as figure, sound, support people to carry out real time information at a distance and exchange and the application system of sharing, carrying out collaborative work.Video conference is very easy between the cooperation member and exchanges truly, intuitively, spread all over all over the world chain type enterprise for branch, and remote teaching has very important effect.But the video conferencing system of prior art has at least two parts to constitute, and video conference terminal and display use inconvenience.
The utility model content
Technical problem to be solved in the utility model is that a kind of projector that carries out video conference is provided.This projector passes through the network multimedia signal receiving, and video and audio signal is carried out encoding and decoding, and vision signal shows that by projector audio frequency passes through loudspeaker plays.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of projector that carries out video conference mainly comprises projector's display terminal and the video conference terminal that is connected network; The described projector that carries out video conference is made up of electronic circuit and optics;
Described optics comprises light source, camera lens and digital micromirror;
In described electronic circuit, network drive is connected with the video conference terminal processor, and the video conference terminal processor is connected with audio decoder, and audio decoder is connected with loud speaker; The video conference terminal processor is connected with the projector processor again, and projector's processor is connected with electric ballast; The video conference terminal processor also is connected with digital-to-analogue/analog to digital converter, and digital-to-analogue/analog to digital converter is connected with digital micromirror.
Preferably, can to select model for use be RTL8139 to described network drive.
Preferably, can to select model for use be BSP15 to described video conference terminal processor.
Preferably, can to select model for use be DDP2000 to described projector processor.
Preferably, can to select model for use be DAD1000 to described digital-to-analogue/analog to digital converter.
The beneficial effects of the utility model are: the utility model is a kind of novel device that video conference terminal and projector are combined, when carrying out Remote Video Conference, do not need to connect outside display device, just can directly pass through projector's display video information; The described projector of video conference that carries out becomes the reception of multimedia messages, processing and display set, and it is more convenient that the user is used.
Description of drawings
Fig. 1 is the syndeton schematic diagram of the projector of the video conference carried out that provides of the utility model.
Embodiment
For further specifying the utility model, now be described in detail in conjunction with the accompanying drawings:
Fig. 1 is the syndeton schematic diagram that can carry out the projector of video conference.
A kind of projector that carries out video conference comprises that mainly two parts constitute: projector's display terminal and the video conference terminal that is connected network.The described projector that carries out video conference is made up of electronic circuit and optics, and wherein electronic circuit part unites two into one the video terminal and the network terminal, and what do not need other auxiliary devices has the simple video conferencing system of a cover of one's own.
Described optics is made of light source, camera lens, digital micromirror substantially.Wherein camera lens can zoom, makes display frame amplify and dwindle; Light source has determined the brightness of real picture, if external environment condition is brighter, but light source is darker, and that picture effect will be very bad; Digital micromirror is the device that the signal of telecommunication changes light signal, and to compare nothing special with common projector.
Described electronic circuit part, network drive is connected with the video conference terminal processor, and the video conference terminal processor is connected with audio decoder, and audio decoder is connected with loud speaker; The video conference terminal processor is connected with the projector processor again, and projector's processor is connected with electric ballast; The video conference terminal processor also is connected with digital-to-analogue/analog to digital converter, and digital-to-analogue/analog to digital converter is connected with digital micromirror.
Wherein electric ballast is the regulating and controlling light source.Network drive is used for connecting network, and the video conference terminal processor receive to be handled multimedia messages, and by projector's processor, convert to can projection video signal format show that the audio format that can play passes through loudspeaker plays.
It is RTL8139 that network drive can be selected model for use
It is BSP15 that the video conference terminal processor can be selected model for use
Selected for use the model of projector's processor is DDP2000
It is DAD1000 that described digital-to-analogue/analog to digital converter can be selected model for use.
Above-mentioned model select the employing of not getting rid of other model for use, all can adopt as long as can satisfy function of the present utility model.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
