    摘要: An image encoding method comprises hybrid digital-analog (HDA) encoding a first image frame to generate first encoded data including a digital part and an analog part and inter-encoding a second image frame according to the digital part of the first encoded data to generate second encoded data.

    摘要: A control method, a task aircraft, a control side, a relay aircraft, and a readable storage medium are provided. The task aircraft flies in an initial mode, and the initial mode includes one of a direct mode and a relay mode. In the direct mode, the task aircraft flies under a direct control of a control side; and in the relay mode, the task aircraft flies under a control of instructions of the control side relayed by a relay aircraft. The control method includes: controlling the task aircraft to fly in the direct mode, when a communication quality under the relay mode is lower than a communication quality under the direct mode; or controlling the task aircraft to fly in the relay mode, when a communication quality under the relay mode is greater than a communication quality under the direct mode.

    摘要: An image processing method includes obtaining a current image frame. The image processing method also includes in response to feedback information, determining a reference image frame for coding the current image frame based on the feedback information. The feedback information is transmitted by a receiver based on a variable feedback time interval, and is configured to indicate a transmission status of an image frame transmitted by a transmitter to the receiver prior to the feedback information. The image processing method also includes coding the current image frame based on an inter-frame coding and the reference image frame to generate coded data. The image processing method further includes transmitting the coded data to the receiver.

    摘要: 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.
