Patent ID: 11882313
Assignee: TENCENT AMERICA LLC
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A device for encoding a video sequence, the device comprising:
at least one memory configured to store program code;
at least one processor configured to read the program code and operates as instructed by the program code, the program code including:
first encoding code configured to cause the at least one processor to apply an interpolation filter to the video sequence,
first obtaining code configured to cause the at least one processor to obtain a difference between maximum and minimum values of a plurality of neighboring samples of a first one among a luma block and related to the video sequence;
dividing code configured to cause the at least one processor to divide the difference into intervals;
first performing code configured to cause the at least one processor to perform a quantization of the difference;
second obtaining code configured to cause the at least one processor to obtain a floor value based on the difference of which the quantization is performed;
third obtaining code configured to cause the at least one processor to obtain a derived value by using at least the difference and the intervals; and
predicting code configured to cause the at least one processor to predict a sample of a different one among a chroma block related to the video sequence, based on the derived value.
