REFERENCE PICTURE MANAGEMENT AND LIST CONSTRUCTION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240114128 titled 'REFERENCE PICTURE MANAGEMENT AND LIST CONSTRUCTION

Simplified Explanation

The patent application describes techniques for encoding video with motion compensation using a compressed bitstream syntax that includes a list of all motion prediction reference frames without distinguishing between short-term and long-term reference frames. The list of reference frames may be provided in a slice header and apply to encoded video data within the corresponding slice. The list may be prefaced with a total number of reference frames, and delta POC reference numbers may be encoded with a flag indicating the sign of the delta POC when the absolute value of the POC is not zero. Additionally, a flag may be encoded for every reference frame indicating if POC information should be used when scaling prediction references, and a weighting parameter may be included when POC information should be used.

• Compressed bitstream syntax includes a list of all motion prediction reference frames without distinguishing between short-term and long-term reference frames.
• Reference frames provided in a slice header and apply to encoded video data within the corresponding slice.
• Delta POC reference numbers encoded with a flag indicating the sign of the delta POC.
• Flag encoded for every reference frame to indicate the use of POC information when scaling prediction references.
• Weighting parameter included when POC information should be used.

Original Abstract Submitted

techniques for encoding video with motion compensation include a compressed bitstream syntax that includes a list of all motion prediction reference frames without distinguishing between short-term reference frame and long-term reference frames. the list of reference frames may be provided in a slice header and may apply to encoded data video data within the corresponding slice. the list may be prefaced with a single number indicating the total number of reference frames. in an aspect delta poc reference numbers may be encoded with a flag indicating the sign of the delta poc when the absolute value of the poc is not equal to zero. in another aspect, a flag may be encoded for every reference frame indicating if poc information should be used when scaling prediction references, and a weighting parameter may be included when poc information should be used.
