JOINT MOTION VECTOR CODING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240195978 titled 'JOINT MOTION VECTOR CODING

The present disclosure discusses techniques for efficient coding of motion vectors in multi-hypothesis coding applications. When coding hypotheses are developed, each with a motion vector identifying a prediction source for a pixel block, a motion vector for one hypothesis may be predicted from another.

• Motion vectors for coding hypotheses can be efficiently coded by predicting one from another.
• Motion vector residuals can be used to represent the difference between developed and predicted motion vectors.
• Predicted motion vectors and residuals can be used to code motion vectors for other hypotheses.
• Single motion vector residuals can be output for multiple coding hypotheses, simplifying the coding process.

Original Abstract Submitted

the present disclosure describes techniques for efficient coding of motion vectors developed for multi-hypothesis coding applications. according to these techniques, when coding hypotheses are developed, each having a motion vector identifying a source of prediction for a current pixel block, a motion vector for a first one of the coding hypotheses may be predicted from the motion vector of a second coding hypothesis. the first motion vector may be represented by coding a motion vector residual, which represents a difference between the developed motion vector for the first coding hypothesis and the predicted motion vector for the first coding hypothesis, and outputting the coded residual to a channel. in another embodiment, a motion vector residual may be generated for a motion vector of a first coding hypothesis, and the first motion vector and the motion vector residual may be used to predict a second motion vector and a predicted motion vector residual. the second hypothesis's motion vector may be coded as a difference between the motion vector, the predicted second motion vector, and the predicted motion vector residual. in a further embodiment, a single motion vector residual may be output for the motion vectors of two coding hypotheses representing a difference between the motion vector of one of the hypotheses and a predicted motion vector for that hypothesis.
