One participant is regarded as one speaker if the one participant speaks longer than the reference time. The video switching system determines a main speaker of the at least one speaker according to the speaking information of the at least one speaker. The video switching system calculates an image switching frequency, and determines whether to switch to a video image of the main speaker according to the image switching frequency. The video switching system calculates a response time if determining to switch to the video image of the main speaker, and adjusts the reference time according to the image switching frequency and the response time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Video switching system and method","description":"A video switching system detects speaking information of at least one speaker in a video conference according to a reference time.
