A device management method for use in a cloud system including a remote device, a mobile device and a cloud server is provided. The method includes the steps of: using, by the mobile device and the remote device, a same login information to log in the cloud server; sending, by the remote device, a push notification message to the mobile device through the cloud server when detecting that a first device is connected to a connection port, wherein the push notification message includes first identification information corresponding to the first device; and in response to receiving the push notification message, identifying, by the mobile device, the first device according to the first identification information to activate a respective application so as to perform data transmission with the first device through the respective application.

Cloud management systems and device management methods thereof

A wireless network connection method for an electronic device is provided, in which a first signal is transmitted to additional electronic device and is utilized to identify the electronic device. When the additional electronic device identifies the electronic device through the first signal, it establishes wireless communication between the electronic device and the additional electronic device. A second signal is transmitted to the additional electronic device. The second signal is an audio signal to instruct the additional electronic device to maintain the wireless communication.

Electronic device and its wireless network connection method

The invention provides a remote control system, including a cloud server, a first device and a portable electronic device. The first device includes a transmission interface for connecting to a second device. The portable electronic device sets up a transmission path to connect with the first device via the cloud server. The first device transmits type information including a type of the transmission interface to the portable electronic device through the transmission path. The portable electronic device encodes original data based on the type information to generate encoded data conforming to the transmission interface, and transmits the encoded data to the first device through the transmission path. The first device transmits the encoded data to the second device through the transmission interface, so as to control the second device.

Remote control system electronic device and remote control method

The present invention provides an audio-data transmission system including a channel encoder, a data modulator and a speaker. The channel encoder is utilized to receive and encode a bit signal and generates an encoding signal. The data modulator is utilized to receive the encoding signal and modulates it to an audio signal whose frequency is on a frequency band. The audio signal includes at least four different sub-audio signals. The frequency band includes at least four sub-frequency bands with different frequencies. The frequencies of the at least four sub-audio signals are respectively on the at least four sub-frequency bands. The speaker is utilized to transmit the audio signal including the at least four different sub-audio signals.

Audio-data transmission system and audio-data transmission method

Presented herein are techniques to reduce error probability and eliminate the lingering signal that causes problems during audio signal data transmission. An electroacoustic transducer of a first electronic device receives a data encoded audio signal that includes modulated digital data therein. The data encoded audio signal is demodulated to produce a present input signal that includes a target frequency and a lingering effect of a previously received data encoded audio signal. Lingering cancellation is performed on the present input signal to produce a present output signal from which the lingering effect of the previously received data encoded audio signal has been removed.
