Background
A video conference system refers to a system in which individuals or groups in two or more different places transmit audio, video and file data to each other through a transmission line and multimedia devices, so as to realize real-time and interactive communication and thus realize a teleconference.
The video conference system is roughly divided into a hardware video conference system based on an embedded architecture and a software video conference system based on a PC architecture. The hardware video conference system realizes video and audio processing, network communication and various conference functions through a DSP (digital signal processor) (microprocessor) and embedded software, and various different terminals are connected into a MCU (micro control unit) for centralized exchange to form a video conference network. The network communication mainly adopts the H.323 protocol standard. The software video conference is a video communication mode based on a PC framework, mainly depends on a CPU to process video and audio coding and decoding work, and has the biggest characteristics of low price, good openness and convenient software integration. But video quality generally cannot surpass hardware video systems.
