Abstract
The invention discloses a video broadcast system which adopts the CAT5UTP twisted-pair video transmission technology and comprises a teacher transmission box and a student receiving box. The teacher transmission box and the student receiving box are connected by special connecting lines, is power supplied through universal serial bus (USB) ports of computers or external transformers, and transferred in a parallel point-to-point video transmission mode. By means of the method, the video broadcast system is stable, perfect in video broadcast effect and more effective in studying.
Description
Technical field
The present invention relates to field of systems software, relate in particular to a kind of audio-visual broadcast system.
Background technology
Along with the development of educational undertaking, the enrollment scale of school constantly enlarges, and students' number constantly increases, and hardware facilities such as teaching also improve thereupon, and still, its improvement is often very unbecoming with the development scale of school.Therefore, under existence conditions, how to improve the management of teaching and the problem that quality has become the urgent concern of people.
Summary of the invention
The technical problem that the present invention mainly solves has provided a kind of audio-visual broadcast system, this system stability, and the visual and sound effects perfection does not give a discount during broadcasting, learns more efficient.
To achieve these goals; Technical scheme of the present invention is a kind of audio-visual broadcast system to be provided, the technology of the audio-visual transmission of this system's employing CAT5 UTP twisted-pair feeder; Comprise that teacher transmits box and student's receiving box; Described teacher transmits box and student's receiving box via special-purpose connecting line, supplies power through the USB mouth or the external transformer of computer, with the point-to-point audio-visual transmission means transmission of parallel connection.
In preferred embodiment of the present invention, described teacher transmits box and comprises 2 groups of video-audio signal I/O.
In preferred embodiment of the present invention, described student's receiving box is provided with the image vernier knob.
In preferred embodiment of the present invention, described student's receiving box connects 2 Student computers.
In preferred embodiment of the present invention, described teacher transmits box through circumscribed line traffic control switching key, switches video-audio signal source and broadcast state.
In preferred embodiment of the present invention, described teacher transmits on the panel of box and student's receiving box and is equipped with double-colored cresset.
In preferred embodiment of the present invention, described teacher transmits box and student's receiving box bottom is magnetic design or firm banking.
A kind of audio-visual broadcast system of the present invention; Adopt the technology of the audio-visual transmission of CAT5 UTP twisted-pair feeder; Compared to the traditional approach that used the series connection of VGA line in the past, the unidirectional computer distance teaching of netting twine type system is with the point-to-point audio-visual conveying type of parallel connection; Every bit all can reach 200 meters farthest, and the visual and sound effects perfection does not give a discount during broadcasting.
Embodiment
Set forth in detail in the face of preferred embodiment of the present invention down, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
The invention provides a kind of audio-visual broadcast system; This system adopts the technology of the audio-visual transmission of CAT5 UTP twisted-pair feeder; Comprise that teacher transmits box and student's receiving box; Teacher transmits box and student's receiving box via special-purpose connecting line, supplies power through the USB mouth or the external transformer of computer, with the point-to-point audio-visual transmission means transmission of parallel connection.
The present invention adopts the state-of-the-art technology of the audio-visual transmission of CAT5 UTP twisted-pair feeder; Replace traditional VGA wire rod; Image quality is ultra clear, and quite succinct and economy can be switched the picture and the sound of teacher's computer the screen and the loudspeaker that are broadcast to all students and play in the part of line configuring.
Teacher among the present invention transmits box and comprises 2 groups of video-audio signal I/O, and the importation can connect the signal of PC/NB simultaneously, is switched the signal source of desire broadcasting by teacher; Output OUT-1 can connect teacher's screen or projector, and OUT-2 is connected to signal multiplier (-icator) along separate routes.This teacher transmits box through circumscribed line traffic control switching key, switches video-audio signal source and broadcast state.
Student's receiving box among the present invention is provided with the image vernier knob, but the distortion that the modifying factor distance is produced and the problem of decay.1 student's receiving box can connect 2 Student computers, can see through student's receiving box quantity that serial connection signal shunt multiplier (-icator) or signal relay shunt multiplier (-icator) expand the desire connection.
Teacher among the present invention transmits on the panel of box and student's receiving box and is equipped with double-colored cresset.Teacher transmits box panel and possesses double-colored cresset, and displayable signal source and switching state are normal or broadcasting; Student's receiving box panel possesses double-colored cresset, can show that switching state is normal or broadcasting.Teacher transmits box and student's receiving box bottom is magnetic design, also can choose firm banking, and convenient various occasions are installed and used.
In the computer teaching process, let teacher's computer picture and real-time computer screen that is sent to all students and the loudspeaker of sound.The student can see complete teacher's demonstration lesson on the computer of oneself, do not receive position effects fully; Let the student see clearlyer, on class can be more wholwe-hearted.After teacher demonstrated end and cancellation broadcast mode, the student can practise on the computer of oneself immediately, makes the absorption of the content of courses more efficient.
A kind of audio-visual broadcast system of the present invention; Adopt the technology of the audio-visual transmission of CAT5 UTP twisted-pair feeder; Compared to the traditional approach that used the series connection of VGA line in the past, the unidirectional computer distance teaching of netting twine type system is with the point-to-point audio-visual conveying type of parallel connection; Every bit all can reach 200 meters farthest, and the visual and sound effects perfection does not give a discount during broadcasting; And two students can share one and receive box, and are quite succinct and economical in the part of line configuring.
The above; Be merely embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range that claims were limited.
