I. Industry Background

• With the continuous growth of China's comprehensive national strength and rapid development of modern information technology, enterprises and institutions are raising higher standards for office informatization. Traditional meeting rooms, primarily used for presentations and discussions, have evolved into multi-functional multifunctional spaces for information exchange. Equipped with projectors, video conferencing systems, recording devices and professional audio systems, modern conference facilities feature more advanced features and more professional configurations while keeping operation intuitive for users.

• Modern office buildings accommodate multiple departments or even multiple organizations that share conference facilities. To improve meeting room utilization, centralized management, unified scheduling, online reservation, and pre-meeting notification have become essential requirementsl.

IV. Design Solution

Multimedia Conference Hardware Deployment

1. Small meeting rooms adopt 65~98-inch all-in-one interactive displays integrating electronic whiteboard, video display, built-in audio and video conferencing capabilities. For larger rooms, appropriate LED screen size is selected based on room dimensions and viewing distance to guarantee clear visibility for all participants.

2. Compared with performance-focused multi-function halls, meeting room public address system is easily overlooked, yet high-quality acoustic environment delivers comfortable volume, clear speech intelligibility and accurate sound localization for natural face-to-face communication. Designed in accordance with GB/T 28049-2011 National Standard for Hall Sound Reinforcement, the system applies stereo configuration for background music and a mono configuration for microphone signals; main and auxiliary speakers are carefully positioned to ensure over 98dB sound pressure and below 8dB steady-state steady-state sound field deviation at rear seating. SK-525U dual-pack wireless microphones serve mobile presentations; 5G wireless digital conference system with auto-tracking camera features flat frequency response, low distortion and long-distance voice pickup to accommodate various speakers.

3. Hishico recording system is configured to record and archive important meetings, supporting real-time interaction, remote guest participation and post-event on-demand playback amid frequent corporate meetings.

4. Point-to-point remote video conference solution requires no additional MCU, enabling seamless across different regions or organizations real-time communication between headquarters and subsidiary branches to boost coordination efficiency.

5. Central control system unifies all AV devices with intuitive operation interface, helping non-technical personnel manage all conference equipment without extensive training.

Cloud-based Conference Administration Platform

• Supported by cloud computing and Internet technologies, the cloud-based conference management platform provides reservation and daily management services via mobile app and web portal, enables standardized end-to-end conference management covering meeting reservation, meeting execution and post-meeting statistical analysis.

• Real-time meeting room occupancy is displayed on management dashboard; Reservation reminders can be sent via WeChat, DingTalk and email; Digital signage at reception areas and room entrances displays real-time meeting schedules and room availability.
