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.

Abstract: A computer-implemented method includes receiving a feedback message from a receiver of image data. The feedback message includes a reference frame identifier associated with a reference frame correctly received or decoded by the receiver. The method further includes determining a difference between the reference frame identifier and a current frame identifier. The current frame identifier is associated with a current frame to be encoded and the difference indicates a number of frames between the reference frame and the current frame. The method also includes encoding the current frame based at least in part on the difference.
