AI Technical Summary

Technical Problem

Existing video decoding technologies struggle to improve compression ratios without compromising image quality, given limited network resources and the need for high video quality.

Method used

The combined inter-frame-intra-frame prediction (CIIP) prediction method is adopted. The boundary strength of the current decoding unit is set to a specific value, and the boundary strength is adjusted according to the conditions of adjacent decoding units. The luminance and chrominance components are processed in combination with the deblocking filter.

Benefits of technology

It improves the compression ratio of video decoding, while reducing block artifacts and enhancing video quality.
