Multichannel studio system and method supporting real-time slow motion

The invention relates to a multichannel studio system and method supporting real-time slow motion. The multichannel studio system comprises a plurality of input ends, video-audio adaptive circuits, a video format judgment device, a video automatic up-down conversion device, a video-audio acquisition cache, a multipath acquisition and recording encoder, a special effect processing cache, a playing delay output cache, a memory, a video-audio output circuit, an output end, a network sharing unit, a central processing unit and a control operation resolving unit. The work of judgment, conversion and file acquisition of a plurality of external signal sources is realized through the devices and units of the multiple paths of video-audio adaptive circuits and the like. Real-time edition and processing work of field signals is implemented through a technology of writing and reading video files at the same time. Through the devices of the special effect processing cache, the output cache, the playing delay output cache, the video-audio output circuit and the like, the work of delayed broadcasting, slow motion broadcasting, clip broadcasting and the like is implemented.
