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

This abstract first appeared for US patent application 18526481 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 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.

Unanswered Questions

How does the technology handle different types of video content, such as high-motion scenes or static images?

The patent application does not specifically address how the technology adapts to different types of video content to ensure optimal encoding efficiency and video quality.

What impact does the inclusion of POC information have on the overall compression ratio of the video data?

The patent application does not provide information on how the inclusion of POC information affects the compression ratio of the encoded video data.

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.
