Problems solved by technology
[0002] With the continuous development of terminal technology and image transmission technology, people can use various smart terminals to watch images and video materials more conveniently. The requirements for image and video quality are increasing. If the signal strength is weak or the interference is large , usually there will be a problem of data packet loss or error, which will cause the quality of image data transmission to decline, or appear stuck, blurred or mosaic, which will affect the user experience. Further, to restore the normal display of the image, it needs to be lost through retransmission or erroneous data packets to restore the video data, which will cause a large delay

The present disclosure relates to an image transmission method and device, which relate to the field of terminal technology and are applied to the sending end. The method includes: when the received data is image data, the processing layer is corrected by the processing layer at the sending end using a preset packaging format. The verification code and the image data are packaged into the first data packet, and the first indication information and the first data packet are sent to the physical layer of the sending end, and the processing layer verification code is a verification generated by the processing layer according to the protocol message in the image data code, through the physical layer according to the corresponding relationship between the indication information and the modulation strategy, determine the first modulation strategy corresponding to the first indication information in the first data packet, and through the physical layer according to the first modulation strategy, the physical layer check code and the second A data packet is modulated into modulated data and sent to the receiving end. The physical layer check code is a check code generated by the physical layer according to the received data packet, which can effectively improve the quality of image transmission.
Description
technical field [0001] The present disclosure relates to the technical field of terminals, and in particular, to an image transmission method and apparatus. Background technique [0002] With the continuous development of terminal technology and image transmission technology, people can use various smart terminals to watch images and video materials more conveniently. The requirements for image and video quality are increasing day by day. If the signal strength is weak or the interference is large , usually there will be problems of packet loss or error, which will cause the quality of image data transmission to decline, or appear stuck, blurred or mosaic, which will affect the user experience. Further, to restore the normal display of the image, it is necessary to retransmit the loss. Or the wrong data packet can restore the video data, which will cause a large delay. SUMMARY OF THE INVENTION [0003] In order to overcome the problems existing in the related art, the pur...
