Patent number: 11109047Abstract: A method for processing and transmitting multimedia signals received from a plurality of channels are provided. The method may include receiving at least two multimedia signals from a plurality of channels, and generating a composite multimedia digital signal by coding the multimedia signals in a frame format. At least one of the multimedia signals may include a video signal. The frame format may include an active zone and a blanking zone, the active zone may be configured to encode at least part of the multimedia signals, and the blanking zone may be configured to encode format information. The method may further include converting at least part of the encoded multimedia signals in the active zone into analog signals to generate a composite multimedia signal. The method may further include transmitting the composite multimedia signal to a receiving device via a transmission medium.Type: GrantFiled: April 16, 2020Date of Patent: August 31, 2021Assignee: ZHEJIANG XINSHENG ELECTRONIC TECHNOLOGY CO., LTD.Inventors: Zhaosheng Du, Genqiang Cui, Bingyun Lyu, Wei Fang
