The multimedia environment or streaming media environment we often talk about in the design of paperless office systems (paperless conference systems, ultra-thin integrated lifts) is both a concept of a space or a regional place, and a combination concept. From the space or regional location, it must have the size and size; from the perspective of combination, the application environment must have an application system composed of multimedia teaching equipment or multimedia audio-visual equipment. Therefore, the application environment design of streaming media recording and broadcasting system must also start from two aspects of space environment and application combination.

1. Sound quality design
The influence of building physical factors on the multimedia application environment is very important, especially for the sound quality effect. We often say that the sound reinforcement system includes two aspects of architectural acoustic conditions and electroacoustic systems. Architectural acoustic conditions refer to acoustic environmental conditions in a given space, such as reverberation time, sound absorption effects, and sound insulation coefficients. The electroacoustic system refers to the rationality of the system configuration and the selection and sound supply scheme of the speaker.
2. Visual design
Visual design involves lighting factors and display system effects in the environmental space.
From the perspective of lighting, pay attention to the resolution and adaptability of the human eye. On the one hand, the influence of environmental lighting factors on the multimedia environment is obvious, for example, the influence of ambient illumination on the visual effect of the display system; on the other hand, the brightness and color temperature of the light affect the clarity and color effect of the photographic image. Wait. The display system effect design should pay attention to the connection between the central field of view, the effective field of view and the central line of sight, the effective line of sight, determine the size of the display large screen, and determine the brightness of the display in combination with the ambient illumination.
3. Equipment selection
With a good design plan, in the case that the building physics and environmental lighting meet the requirements, the equipment selection factor is also more critical, and the equipment with good cost performance is the primary consideration. Below are some of the quality factors for device performance.
(1) The frequency response range, signal-to-noise ratio, and Q value of the audio device determine the audio effect and speech intelligibility.
(2) Resolution, contrast, brightness (ANSI lumens index), video signal to noise ratio, compression ratio, and code rate determine the visual effect.
Multimedia audio-visual systems and streaming media recording systems have a common feature in system integration, that is, "short board effect" or "barrel effect" must be considered between devices and devices, between systems and systems. Harmony and match.
4. Integration Technology
Sophisticated equipment requires excellent design techniques and construction techniques. Therefore, system integration technology is also critical to the construction of multimedia environments. For example:
(1) Balanced and unbalanced connection technology in audio systems, speaker layout and sound supply scheme.
(2) The serial port and IR technology are applied to the anti-interference, reliability and stability of the central control system.
(3) The friendliness of the recording and broadcasting system and the operation interface of the central control system. (Paperless conference system, ultra-thin one lift)
