METHOD AND DEVICE FOR VIDEO SIGNAL PROCESSING BY USING EXTERNAL PREDICTION Russian patent published in 2023 - IPC H04N19/105 H04N19/58 H04N19/70 

FIELD: methods and devices for processing video signals using external prediction.

SUBSTANCE: invention relates to methods and devices for constructing a list of reference frames for predicting the current frame. The effect is achieved as the method for processing a video signal according to the invention includes a step for generating a reference frame list for a current frame in a video signal, and a step for predicting the current frame by using the reference frame list, wherein the step for generating the reference frame list includes: a step for obtaining a frame sequence number difference (POC) between a frame associated with the first entry and another frame when the first entry of the reference frame list corresponds to a short-term reference frame (STRP) entry; and a step for obtaining a module POC value for a frame associated with the second reference frame list entry when the second entry corresponds to a Long Term Reference Frame (LTRP) entry. A reference frame list for frame identification can be simply and efficiently generated to improve compression performance and reduce computation time.

EFFECT: effect of the invention is increased efficiency of video content processing.
