Abstract RU 2690220 C1

FIELD: data processing.

SUBSTANCE: invention relates to video encoding and decoding with prediction. Decoding, by means of video prediction encoding device, generated compressed image data also comprises decoding information on display order and information on reference image of each of images included in compressed image data, wherein encoding, by prediction video coding device, also comprises, in accordance with information on reference image, coding, using a reference image, wherein the first image precedes the random access image in the display order and follows the random access image in the encoding order, and encoding a second image which follows the random access image in a display order, using the random access image as a reference image, regardless of any reference image preceding the random access image in encoding order or in display order.

EFFECT: technical result is higher efficiency of encoding and decoding video.
