Abstract: A method for selecting a working wireless communication channel based on spectral estimation includes determining a sub-set of wireless communication channels from a set of wireless communication channels of a working frequency band. A superposition of channel frequency bands of the wireless communication channels in the sub-set covers the working frequency band. The method further includes performing a noise level measurement on each wireless communication channel in the sub-set to obtain a spectral estimation result for each wireless communication channel in the sub-set. The method further includes calculating a spectral density distribution across the working frequency band based on the spectral estimation results of the wireless communication channels in the sub-set. The method further includes selecting, according to the spectral density distribution across the working frequency band, one of the wireless communication channels from the set as the working wireless communication channel.

Abstract: An image processing method includes a transmitting terminal receiving a feedback message sent by a receiving terminal. The feedback message indicates a reception state of a received image frame sent by the transmitting terminal and received by the receiving terminal before the receiving terminal sends the feedback message. The method further includes acquiring a target image frame, encoding the target image frame according to a preset error correction mechanism to generate encoding data of the target image frame in response to the feedback message indicating a reception error, and sending the encoding data of the target image frame to the receiving terminal.

Abstract: An image processing method includes sending, by a receiving terminal to a transmitting terminal according to a feedback time interval, a feedback message indicating a reception state of a received image frame sent by the transmitting terminal and received by the receiving terminal before the feedback message is sent; upon detecting a reception error of a target image frame before a first time point, sending a first feedback message indicating the reception error to the transmitting terminal at the first time point; and upon receiving, after the first time point and before a second time point, encoded data of the target image frame obtained according to an error correction mechanism from the transmitting terminal, sending a second feedback message indicating a correct reception to the transmitting terminal at the second time point. A time period between the first and second time points equals the feedback time interval.
