Recording and broadcasting integrated machine

HD recording and broadcasting system V3.0 can integrate and synchronize recording the video, audio and electronic equipment image ng computers, video booths, etc.) on site, and generate standardized streaming media files for live broadcasting, storage, post-editing and on-demand.The classroom equipped with record and broadcast devices is the outcome of streaming-media technology development and teaching pattern innovation, which meets the needs of long-distance education, exquisite course and teaching evaluation.HD recording and broadcasting system V3.0 can record all video and audio ers, students and courseware synchronously, clearly and undistorted in real time, generate multi-screen and film courseware in real time, and upload them automatically. Restore the teaching reality, record and save the teaching scene in real time, and broadcast the teaching content synchronously. Accumulate exnt network courses resources quickly, promote teaching research, facilitate teaching evaluation and improve teaching quality.Seven functions1. Recording function2. Guiding function3. Live broadcast system4. Location tracking and switching functions5. Synchronous classroom6. Interactive meeting7. Live broadcast managementRecording systemIt adopts many advanced technologies, such as face image recognition, moving object judgment, image recognition, tracking and switching technology.The whole classroom can be automatically switched to shoot by high-definition camera. There will be no tracking or switching jitter in the image, and the switching between the images is smooth.Teacher's camera: switching to the speaker`s image smoothly and stably.Blackboard camera: The software can estimate the speaker's blackboard action ,and automatically switch to blackboard shooting mode.Student Camera: Without the aid of periral equipment, a student stands up and automatically switches to the student video, sits down and switches to the teacher's master video. The whole process is fully automatic.Advantages: The whole process can achieve teacher-student interaction scenes and blackboard close-up omni-directional tracking and switching (optional mode) shooting without manual intervention. Auto zoom can make the screen fade in and fade out, and it also can be operated manually.Playback system1.Internet viewingThe system records and maintains the teaching situation in real time, uploads and distributes automatically to the network, and the viewer watches independently through IE, which is clear and smooth. At the same time, the single screen and multi-screen courseware or multi-screen layout pictures are generated to meet the needs of teaching evaluation and students'review after class.2. WEB meetingThe system recording and broadcasting system supports seamless integration with the pure WEB conference system, and the real-time recording and broadcasting classroom is introduced into the WEB conference system.3.Interactive teaching and synchronous classroomThe live broadcast can be transmitted to other classrooms to achieve the effect and function of interactive teaching and synchronous classroom.4. Output formatStandard FLASH or MP4 streaming media format Advantages: while ensuring the minimum file, it can also use traditional non editing arbitrary editing.System advantage1. Courseware modes are diverse: support single-screen film mode, multi-screen, can produce single-screen film mode and multi-screen mode courseware in the same recording. Support export as SCORM standard courseware and single EXE courseware file.2. index automatic generation: PPT, word title automatically generate courseware index directory, and can edit index.3. video quality is high, data content of screen content editing is small: at the same time, it supports four HD video input. Screen content acquisition does not require hardware equipment, software acquisition and compilation through the network, VGA acquisition card conversion effect is clearer than the same period, the amount of file data with small.4. Video source is abundant: In addition to conventional audio and video acquisition card acquisition, it also supports remote acquisition of IPCamera and encoder.5. Specialized coding, standardized output: Professional standard MP4 or FLV rather than (WMV7WMV9, MPEG2) this low-efficiency coding method, the output file is standard FLV streaming media format, supporting traditional non-editing arbitrary editing.6. Troubleshooting and remote assistance: support mute detection, audio source input problem prompting; support remote assistance to teacher's teaching machine in recording process7.B/S architecture, web access is convenient: recording can be simultaneously multi-screen mode and Microsoft Streaming Media Server movie mode live broadcast. Support local LAN, Wan broadcast live through IE. You can exchange video and screen windows at random, and each part can be played in full screen. Support unicast and multicast mode.8. Simultaneous and accurate editing: All kinds of courseware (single screen, multi-screen courseware) can be synchronized editing, the editing can be accurate to the frame, the video at the incision is clear and smooth. It supports the simultaneous merging of different sizes of courseware. Support encoding parameters to be re encoded after adjustment. Ppt part of the error text can be corrected in the screen recording file.
