Projector system and method for operating projector system

A projection system comprising:

• an electronic device;
• an adapter device connected to the electronic device, and configured to receive a control command output by the electronic device;
• and
• a projection device adapted to be connected to the adapter device, and comprising a first control circuit and a second control circuit,
• wherein the first control circuit is configured to perform a booting operation on the projection device according to the control command in a powered-off state of the projection device, and the second control circuit is configured to perform a power-off operation or a running operation on the projection device according to the control command in a booted-up state of the projection device;
• wherein the adapter device is configured to convert a communication protocol of the control command from a first communication protocol into a second communication protocol;
• wherein the projection device further comprises:
• a first switch circuit connected to the adapter device, and configured to receive the control command conforming to the second communication protocol from the adapter device and output the control command;
• a third control circuit connected to the first switch circuit, and configured to receive the control command conforming to the second communication protocol from the first switch circuit and convert the control command conforming to the second communication protocol into a control signal conforming to a third communication protocol;
• and
• a fourth control circuit connected between the third control circuit and the first control circuit and between the third control circuit and the second control circuit, and configured to receive the control signal conforming to the third communication protocol from the third control circuit and output the control signal to the first control circuit or the second control circuit.

An operation method of a projection system, wherein the projection system comprises a projection device, an adapter device, and an electronic device, the projection device comprises a first control circuit and a second control circuit, and the operation method comprises:

• by the adapter device, receiving a control command output by the electronic device, converting a communication protocol of the control command from a first communication protocol into a second communication protocol, and transmitting the control command to the corresponding projection device;
• performing a booting operation on the projection device by the first control circuit according to the control command in a powered-off state;
• and
• performing a power-off operation or a running operation on the projection device by the second control circuit according to the control command in a booted-up state;
• wherein the projection device further comprises a first switch circuit and a second switch circuit, and the operation method further comprises:
• by the first switch circuit, receiving the control command conforming to the second communication protocol from the adapter device and outputting the control command;
• by the second switch circuit, receiving the control command conforming to the second communication protocol from the first switch circuit and outputting the control command to the first control circuit or the second control circuit.
