Encoding method, encapsulation method, display method, apparatus, and electronic device

A data encapsulation method, comprising:

• obtaining bitstream data by encoding an image using an encoder, wherein the encoder is a single-scale encoder that can perform encoding on an image at only one encoding scale and output bitstream data at only one encoding scale, and wherein the method further comprises determining whether to perform multi-scale encoding on the image in association with at least one of:
• an importance of the image to encoding and decoding of another image in video data to which the image belongs satisfies a first condition, an impact degree of bitstream data corresponding to the image on a network satisfies a second condition, or a predicted image quality of the image satisfies a third condition;
• obtaining description information of the bitstream data;
• obtaining encapsulated data by encapsulating the bitstream data and the description information of the bitstream data;
• and
• storing or transmitting the encapsulated data.

A display method, comprising:

• obtaining a plurality of reconstructed images by decoding bitstream data using a decoder, wherein the bitstream data is generated by encoding an image using a single-scale encoder that can perform encoding of an image at only one encoding scale and output bitstream data corresponding to only one encoding scale, and wherein the encoding of the image is performed in association with determining whether to perform multi-scale encoding on the image based on at least one of:
• an importance of the image to encoding and decoding of another image in video data to which the image belongs satisfies a first condition, an impact degree of bitstream data corresponding to the image on a network satisfies a second condition, or a predicted image quality of the image satisfies a third condition;
• obtaining a plurality of groups of description information corresponding to the plurality of reconstructed images, wherein at least one group of description information, in the plurality of groups of description information, includes first frame identification information;
• and
• in association with only one of the plurality of groups of description information includes the first frame identification information, selecting and displaying a reconstructed image corresponding to the first frame identification information, or
• in association with at least two groups of description information, in the plurality of groups of description information, include the first frame identification information, selecting a reconstructed image from at least two reconstructed images corresponding to the first frame identification information, and displaying the selected reconstructed image.

An electronic device, comprising:

• a processor;
• and
• a memory configured to store program instructions which, when executed by the processor, cause the electronic device to:
• obtain an image for encoding;
• determine N encoding scales for the image, wherein Nis an integer greater than 1;
• determine N groups of encoding parameters corresponding to the N encoding scales, wherein each encoding scale, from the N encoding scales, corresponds to one group of encoding parameters from the N groups of encoding parameters;
• and
• obtain N groups of bitstream data by encoding the image N times by repeatedly using a single-scale encoder based on the N groups of encoding parameters, wherein the single-scale encoder is an encoder that can perform encoding on an image at only one encoding scale and output bitstream data at only one encoding scale, and
• wherein the program instructions further cause the electronic device to determine whether to perform multi-scale encoding on the image in association with at least one of:
• an importance of the image to encoding and decoding of another image in video data to which the image belongs satisfies a first condition, an impact degree of bitstream data corresponding to the image on a network satisfies a second condition, or a predicted image quality of the image satisfies a third condition.
