Broadcast AVoIP Solution

                                          This solution adopts an AVoIP architecture to build a fully IP-based studio audio and video production system, enabling full-chain service delivery covering studio front-end acquisition, IP-based signal transmission, program production scheduling, monitoring, and broadcast distribution.

The front-end acquisition layer deploys 4K/8K cameras, studio microphones, the main operation console, and background large screens. Audio and video signals are aggregated through access switches and then sent to the core IP switch. Leveraging AV over IP technology, SDI/IP audio and video signals are converted into IP streams for network transmission. The core network is equipped with media processing servers to perform signal encoding, decoding, and storage; the director control console integrates an audio mixing console, a video signal switcher, and a director control workstation to achieve centralized scheduling, switching, and control of multiple audio and video signals. The program production and system management layer includes program production, signal scheduling, encoding and transmission, and a system management platform, responsible for program editing, route management, post-encoding processing, and monitoring of the status of all network devices; it also outputs multiviewer streams and monitoring streams, which are sent to the multiviewer large screen and real-time monitoring workstations to complete on-site real-time monitoring. The processed program signals are ultimately pushed to the broadcast/distribution network to complete program online broadcasting.

The entire system carries high-definition/ultra-media audio and video over an IP network, breaking the limitations of traditional SDI cables. It features flexible signal routing, centralized management and control, and elastic scalability, making it suitable for radio and television studio 4K/8K program production, on-site directing, signal monitoring, and broadcast distribution business scenarios.
