According to the plan, colleges and universities can video record high-quality course content in more detail, exchange course content interactively, convert it into higher-quality course video resources, create a high-quality educational resource library, and assist teachers to do a good job in after-class reflection and classroom teaching. In the work of teaching, teaching, and scientific research, and as a demonstration of classroom teaching, it is shared with teachers and students in remote areas for reference learning and training, to achieve a balanced development trend of teaching resources.

02 Where is the "good" in the four-camera interactive recording and broadcasting class?

Compared with the traditional classic recording and broadcasting plan, the seewo four-camera interactive recording and broadcasting classroom plan pursues perfection for a more lightweight classic recording and broadcasting experience.

Four-camera recording and broadcasting, all-round ultra-clear recording of the key points of each classroom teaching

In the recording and broadcasting, the teacher's behavior in each classroom teaching and the main performance of the students' classroom personal behavior have the practical significance of certain teaching and scientific research value. Teachers can evaluate and think about their classroom teaching from the timely feedback of students in the classroom, which is conducive to improving and improving teaching ability.

Therefore, the four-camera interactive recording and broadcasting classroom planning program released by seewo is equipped with four cameras for video recording of four locations, helping teachers to record the whole process of classroom teaching accurately and meticulously. Among them, 2 PTZ cameras record the close-up of the teacher and students respectively, and the 2 4K high-definition surveillance cameras each record the panorama of the teacher and the students. Compared with the original video recording of two surveillance cameras with four locations, the four-camera equipment records real, cheerful, lifelike, and colorful classroom teaching.

In addition, the PTZ camera has a built-in 4k high-definition COMS sensor, which can shoot UHD ultra-high-definition high-quality picture quality, and the ±170° super-large rotating angle of view can be applied to a variety of scenes, and teachers and students can describe special scenes. The actual effect of the shooting is higher quality, and the open courses are recorded and stored in detail, which is conducive to the discussion of learning and training for teachers inside and outside the school, so that knowledge sharing can break away from regional boundaries, and maximize the use of high-quality educational resources.

360° accurate pickup and clear restoration of the sound of on-site teaching

The supercardioid bias feature has higher frequency stability, more accurate sound pickup, and ensures the sound effect of video recording in all directions, and ensures that the sound collection in classroom teaching is clear and accurate. In addition, biased towards the principle of a built-in noise reduction circuit in the microphone, it can be very good at considering the constant noise in the classroom, reducing the noise in the whole process of collecting sound, and making the actual effect of sound pickup in the whole process of video recording higher quality, creating a solid quality sound. Record the class.

Sound field enhancement creates an ideal class experience
