Method for image transmitting, transmitting device and receiving device

A method for image transmitting, executed in a receiving device, the method comprising:

• establishing a first channel, a second channel and a third channel;
• receiving the first data, the second data, and the third data respectively through the first channel, the second channel, and the third channel to a receiving device, wherein an image of a video is divided into a region of interest and a background region, the first data is data of the region of interest, the second data is data of the background region, and the third data is obtained by encoding the first data through fountain coding;
• analyzing a current network condition and replying the current network condition back to the transmitting device;
• and
• restoring the first data according to a second preset algorithm and playing the restored image.

A transmitting device, the transmitting device comprising:

• at least one processor;
• a storage unit;
• and
• one or more programs that are stored in the storage unit and executed by the at least one processor, the one or more programs comprising instructions for:
• establishing a first channel, a second channel and a third channel;
• obtaining an image of a video, and dividing the image into a region of interest and a background region;
• obtaining a first data of the region of interest and a second data of the background region, and encoding the first data through fountain coding to obtain a third data;
• transmitting the first data, the second data, and the third data respectively through the first channel, the second channel, and the third channel to a receiving device;
• receiving a network condition feedbacked by the receiving device, and determining whether the network condition matches a preset condition;
• and
• when the network condition matches the preset condition, compensating the first data according to a first preset algorithm.

A receiving device, the receiving device comprising:

• at least one processor;
• a storage unit;
• and
• one or more programs that are stored in the storage unit and executed by the at least one processor, the one or more programs comprising instructions for:
• establishing a first channel, a second channel and a third channel;
• receiving the first data, the second data, and the third data respectively through the first channel, the second channel, and the third channel to a receiving device, wherein obtaining a image of a video is divided into a region of interest and a background region, the first data is data of the region of interest, the second data is data of the background region, and the third data is obtained by encoding the first data through fountain coding;
• analyzing a current network condition and replying the current network condition back to the transmitting device;
• and
• restoring the first data according to a second preset algorithm and playing the restored image.
