DATA TRANSMISSION SYSTEM, PROJECTOR, AND DATA TRANSMISSION METHOD

The present invention has a first device connected to a first external device by using a first transmission method, and a second device connected to a second external device by using the first transmission method, wherein the first device and the second device perform FPA for data transmission by a second transmission method different from the first transmission method between the external devices, which are respectively connected to equipment using the first transmission method, and the first device is connected to the second device by using the second transmission method. When an operation mode with respect to the first transmission method of the first device and an operation mode with respect to the first transmission method of the second device differ, data possessed by the first external device or the second external device is transmitted respectively to the second external device or the first external device via the first device and the second device. 本发明提供了种在外部设备之间根据第二传输方案进行数据传输的数据传输系统，该外部设备中的每个都连接至根据第
