Abstract
A projector capable of sharing an image of a slide played immediately is further provided with a signal processing device (101) and a network device (102) in addition to the components and the functions of the common projector. The signal processing device (101) converts an input video signal into a video data stream and provides the video data stream for each network terminal (4) for extraction in a real time way through the network device (102). In some large-scale conferences, as the conference site is wide and there are many participants, not every participant in every position can see the screen (2) of the projector clearly; however, with the projector (1) disclosed by the invention, the participant only needs to carry the network terminal (4) capable of accessing to the Internet, like a notebook computer, in order to extract the video data stream from the projector (1) through the notebook computer; therefore, all the participants can see the image content the same as that on the screen (2) immediately or download the slide files of a speaker; and the video data steam can be stored in the computer for subsequent review.
Description
[technical field]
The present invention relates to a kind of projector that can share institute's broadcast transparency image immediately.
[background technology]
When general big-and-middle-sized meeting is held, major part all provides projector apparatus to use for the speaker, can make things convenient for the speaker in the speech process, play some transparencys and cooperate the speech content, the person is easier to understand speaker's speech to make the conference participation, particularly some academic conferences, most of speaker can make some transparencys in advance and cooperate speech.But because the restriction in meeting place; the person does not see the transparency content that Chu plays to divide the conference participation through regular meeting's generating unit; more particularly contain transparency than micrographia; people from projector screen than distant positions; just can not see the micrographia in the transparency clearly; influenced them and understood speaker's speech, being one has problem to be solved.
[summary of the invention]
Purpose of the present invention, be to provide a kind of projector that can share institute's broadcast transparency image immediately, the transparency image that projector play in the meeting can be distributed to other-end by video data stream communications (Video Streaming Technologies) with real-time mode and share.
The object of the present invention is achieved like this, adopt a kind of like this projector, the vision signal that is mainly used in input is converted to the image ray cast on screen, it is characterized in that, described projector (1) is except the assembly and function that possess general projector, also be provided with signal processing apparatus (101) and network equipment (102), wherein, described signal processing apparatus (101) is mainly used in the vision signal from video inputs mouth (103) input is converted to video data stream, and described video data stream is offered and this network equipment (102) network terminal of network connectivity (4) extraction mutually with real-time mode by network equipment (102).
So just realized purpose of the present invention.
When projector of the present invention (1) plays the transparency image, but as long as use the network terminals such as notebook (4) of line online, be wired to projector of the present invention (1), the video data that just can download in progress transparency flows in the notebook to be play, and just can know in real time in the notebook screen and see the identical presentation content with projector screen (2).
