2) 6-path concurrent video processing

The HD video recording system adopts HD shot technology in whole process, can conduct the 6-path concurrent signal 1080P50f/60f, guarantee high quality of collected input signals. Furthermore, to make sure the effect of live recording, according to the environmental situation of recording, can support mixed input of SDI video signal, far-end video signal, HDMI HD video signal, make sure of the best effect of video recording.


3) Remote B/S broadcasting instruction and local broadcasting instruction

The recording system support 2 modes of broadcasting instructions - remote B/S broadcasting instruction and local broadcasting instruction, the remote B/S broadcasting instruction can let users to use the function of professional broadcasting instruction from remote which is accessible by network, without plug-in requirement, it is easy to use. The system supports the mode of local broadcasting instruction, you only need a mouse and display screen to get local broadcasting instruction, no delay, high fluency. Both broadcasting modes supports the operation of 6-path video preview, Single and multi-stream live output, video switch, audio adjustment, recording mode, special effect, movie head and end, caption, logo, camera control, it is easy to use and flexible.


4) Various Recording Modes

Support single and multi stream recording modes, single stream mode supports the models of single-picture and multi-pictures, and switches in various display modes. Multi-stream recording mode support 1-pat movie video and 5-path video 1080P/30ffps individual decoding, and save as independent 6-path video, the video has no picture covered on each other, thus save complete materials for future editing.


5) Multi-point Interactive Education

The Integrated Recording and Broadcasting Machine has the function of remote education, the built-in 4-point MCU multi-point interactive function, can open the function of 4-point interactive education simultaneously; function of video conference end, support SIP protocol, can directly interconnect to multi-point interactive platform MCS and conference TV end, apply to simultaneous class education in big scale in the district or city.


6) Easy operation, One-key Conduct

Teacher can use the key on the control panel, operate by one-key, start and stop video recording. Also can set up automatic or manual recording on the network web page. If automatic recording, only need to press “start”. Press stop after class, the video of the whole class is finished. All other operation systems run automatically, simple and easy, very convenient.

1.9 Image Tracking System


1) Teacher Image Behavior Analysis

When the system detects the teacher moving much in the classroom, priorly adopts dynamic camera mode with mid-shot and full view; when the teacher sits or stays in the classroom, priorly adopts static mode, with mid-shot and close shot. In the situation of multimedia classroom, interactive teaching machine is necessary, so before adopting the image recognition technology to track the teacher’s behavior, we must consider the interference of these image sources, to avoid mis-recognition, the simulation of real teaching scene was fully carried out, after various simulation test on tracking scenes, in the software setting, shielding area is allowed in the setting, to avoid the interference of animations, shadows and fluttering curtain on the tracking effect.


2) Students Image Behavior Analysis

In traditional tracking, it is not allowed that someone passes the corridor of the classroom, but in actual situation of class, a passing class teacher will surely affect the normal tracking on students, thus rubbish shots will appear. Considering actual teaching scene, it is allowed to manually set the image recognition mask area during software debugging, thus set the effective tracking area according to the environment on site and avoid rubbish spots.


3) Advanced Comprehensive Anti-shake Technology

Having owned “wide scene image anti-shake technology”, while supporting innovative “narrow scene anti-shake technology”.

Wide scene image anti-shake technology: allow to neglect the teacher’s moving within a setting scope, keep camera fixed, guarantee the image smooth and stable, avoid the image bouncing or moving.

Narrow scene anti-shake technology: in the narrow scene of 1.8~2.4m, under the moving speed of 0~3m/s, tracking people precisely, no shaking, no missing. In the meanwhile of tracking the teacher precisely, completely avoid the problem of shaking spots due to large body movements; it is a breakthrough in this field to solve the problem existing many years.


4) Adapts to Teacher’s height

Adjustment according to different teacher’s height, the teacher’s camera is on the proper position all the time, ensures reasonable composition. The tracking process is continuous, stable, smooth, the image output is stable.


5) Teacher’s Recognition

To complete the construction of curriculum information, the system automatically performs face recognition of the teacher, recognizes the teacher’s name and identification and feedback the recognized information on the basic data.


6) Tracking switching strategy customization

The image positioning system can intelligently adjust the camera strategy during the class according to the special scenic conditions and user’s need, fulfill the whole teaching process, maximize to reach the effect of manual shooting.
