Cloud director method and device based on SEI time code information

The invention relates to a cloud director method and device based on SEI time code information, and the method comprises the steps: a cloud server receives code streams and depacks the code streams into TS streams, each TS stream is synthesized by additional information and a serial digital interface signal through an encoder, the additional information forms an SEI frame which is inserted in front of a video frame, and the SEI frame comprises time code information and video channel information; reading the TS stream, comparing time code information and video channel information in the SEI frame with switching information provided by a cloud director station, if the information is consistent, decoding a picture group corresponding to the SEI frame into a baseband video signal, transmitting the baseband video signal to the cloud director station, and transmitting the baseband video signal to the cloud director station according to the time code information. The method comprises the following steps: carrying ou
