专利汇可以提供Facsimile communication system专利检索,专利查询,专利分析的服务。并且A facsimile communication system is described wherein the transmission of data between a transmitting and receiving apparatus over a voice quality transmission medium is accomplished by providing spectrum compressing encoding of a video signal and by frequency modulation and vestigial sideband transmission of the frequency modulated video signal. In a principal mode of operation, the transmission of video data is preceded by receiver alerting, equalizing, synchronizing and scan pitch signals for respectively shifting the receiver from a standby to an operating status, for connecting distortions in the transmission medium, for causing line by line synchronization between sending and receiving units and for establishing the scanning pitch at the printing unit. A transceiving unit of the system when operating as a receiver in the principal mode generates reverse signalling information for acknowledging a ready to receive status at the initiation of communication and a printer ready status for enabling the transmission of video information. A high degree of reliability in interaction between the sending and receiving units is thereby imparted to the system and facilitates scanning and electrostatographic printing techniques. The transceiving system of the invention is further adapted for operating in optional modes including an automatic document feeding mode, an unattended sending mode and a printer polling mode. The communication system is further adapted to operate with existing facsimile systems which transmit at relatively lower document transmission rates, exhibit different signal formats and have different internal controlling.,下面是Facsimile communication system专利的具体信息内容。
