Method and system of processing information flow and method of displaying comment information

A method of synchronously displaying images frames, mask frames and comment information, comprising:

• receiving a second data unit a second information stream and comment information, wherein the second information stream is generated by synthesizing at least one image and mask frame data corresponding to the at least one image, the second information stream comprises a plurality of second data units, and the second data unit comprises meta-information and second data information;
• obtaining an image and mask frame data corresponding to the image by decoding the second data information, wherein the mask frame data comprise a mask frame generated based on a main area of the image, the mask frame data further comprise a timestamp offset indicative of a time difference between a timestamp of the mask frame and a playing timestamp of the image, and the main area of the image comprises a person area, an animal area, a landscape area, an architectural area, an artwork area, and a text area in the image;
• and
• synchronously displaying the image, the mask frame corresponding to the image, and the comment information based on the meta-information and the timestamp offset.

A system of processing information flow, comprising:

• at least one processor;
• and
• at least one memory communicatively coupled to the at least one processor and storing instructions that upon execution by the at least one processor cause the system to:
• receive, from a first client computing device, a first data unit among a plurality of first data units comprised in a first information stream, wherein the first data unit comprises image data and meta-information;
• obtain an image and a first timestamp corresponding to the image by decoding the first data unit;
• identify a main area the image, wherein the main area of the image comprises a person area, an animal area, a landscape area, an architectural area, an artwork area, and a text area in the image;
• generate mask frame data based at least in part on the identified main area of the image, wherein the mask frame data comprise a timestamp offset associated with the first timestamp;
• and
• generate a second information stream by synthesizing the image and the mask frame data corresponding to the image.

A system of synchronously displaying images frames, corresponding mask frames and comment information, comprising:

• at least one processor;
• and
• at one memory communicatively coupled to the at least one processor and storing instructions that upon execution by the at least one processor cause the system to:
• receive a second data unit in a second information stream and comment information, wherein the second information stream is generated by synthesizing at least one image and mask frame data corresponding to the at least one image, the second information stream comprises a plurality of second data units, and the second data unit comprises meta-information and second data information;
• obtain an image and mask frame data corresponding to the image by decoding the second data information, wherein the mask frame data comprise a mask frame generated based on a main area of the image, the mask frame data further comprise a timestamp offset indicative of a time difference between a timestamp of the mask frame and a playing timestamp of the image, and the main area of the image comprises a person area, an animal area, a landscape area, an architectural area, an artwork area, and a text area in the image;
• and
• synchronously displaying the image, the mask frame corresponding to the image, and the comment information based on the meta-information and the timestamp offset.
