CONTEXT-BASED ADAPTIVE BINARY ARITHMETIC CODING (CABAC) CONTEXT MODELING WITH INFORMATION FROM TEMPORAL NEIGHBORS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18215244 titled 'CONTEXT-BASED ADAPTIVE BINARY ARITHMETIC CODING (CABAC) CONTEXT MODELING WITH INFORMATION FROM TEMPORAL NEIGHBORS
Simplified Explanation: The patent application discusses methods and apparatuses for video encoding/decoding, focusing on context-based adaptive binary arithmetic coding (CABAC) models.
- The apparatus for video decoding includes processing circuitry that receives coded information of a current block in a current picture from a coded video bitstream.
- The coded information contains a syntax element associated with the current block, indicating a decoding parameter.
- The processing circuitry determines a CABAC context model based on a temporally co-located block in a different picture from the current picture.
- The syntax element is decoded based on the CABAC context model, and the current block is reconstructed accordingly.
Key Features and Innovation:
- Utilizes context-based adaptive binary arithmetic coding (CABAC) models for video decoding.
- Enhances decoding efficiency by using temporally co-located blocks for context determination.
- Improves video quality by accurately reconstructing blocks based on decoded syntax elements.

Original Abstract Submitted
Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus for video decoding includes processing circuitry. The processing circuitry receives coded information of a current block in a current picture from a coded video bitstream. The coded information includes a syntax element associated with the current block, the syntax element indicates a decoding parameter of the current block. The processing circuitry determines a context-based adaptive binary arithmetic coding (CABAC) context model associated with the syntax element based on at least a temporally co-located block of the current block. The temporally co-located block is in a different picture from the current picture. Further, the processing circuitry decodes the syntax element based on the CABAC context model, and reconstructs the current block based on the syntax element that is decoded based on the CABAC context model.
