SYSTEMS AND METHODS FOR SIGNALING OF DOWNSAMPLING FILTERS FOR CHROMA FROM LUMA INTRA PREDICTION MODE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18144042 titled 'SYSTEMS AND METHODS FOR SIGNALING OF DOWNSAMPLING FILTERS FOR CHROMA FROM LUMA INTRA PREDICTION MODE
Simplified Explanation
The various implementations described herein include methods and systems for decoding video. In one aspect, a method includes receiving a video stream having a sequence of frames. The sequence of frames includes one or more key frames. Each key frame has a respective downsampling filter type. The method includes, in accordance with a determination that a current frame corresponds to a first key frame, retrieving, from the video stream, a syntax element associated with a first downsampling filter type associated with the first key frame. The method includes a luma block of the current frame and a predefined set of frames immediately after the current frame using the first downsampling filter type to obtain downsampled frames. The method includes predicting a chroma block of the current frame based on the downsampled frames.
- Method for decoding video frames with key frames and downsampling filter types
