Abstract
A portable electronic device and a transmission control method. The portable electronic device includes a transmission interface, a power management circuit that detects an external device connected to the transmission interface as a power supply or receiving device, a switching circuit, and a control circuit that controls the switching circuit by a detection result of the power management circuit. When a first transmission channel is selected for conduction with the transmission interface, the control circuit outputs a device identification signal via the first transmission channel to identify the external device. When the external device is identifiable, an image signal of the external device is received via the first transmission channel. When the external device is not identifiable, the switching circuit is controlled to select a second transmission channel for conduction with the transmission interface, and signal transmission with the external device is performed via the second transmission channel.
