An ability to transmit at any time is possessed by intercepting screen content at regular time and performing compression, which improves transmission effects and shortens transmission time. A comparison of the intercepted screen content and intelligent determining on the synchronous image is performed by using eigenvalues parsed and obtained during image compression. In addition, synchronous transmission is realized automatically without manual operations. Moreover, the transmission of repeated screen content is avoided to the greatest extent, which reduces storage pressure on student user terminals and ensures content comprehensiveness. Further, marking and judging on the screen image content improve the efficiency of student reviews. For example, students can directly see the last few pages of each blackboard-writing during reviews."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image synchronous display method and device","description":"A synchronous displaying method and a synchronous displaying apparatus are provided.
