HASH-BASED ENCODER DECISIONS FOR VIDEO CODING - A simplified explanation of the abstract

• This abstract for appeared for US patent application number 18217034 Titled 'HASH-BASED ENCODER DECISIONS FOR VIDEO CODING'

Simplified Explanation

The abstract discusses new advancements in encoder-side decisions using hash-based block matching. These innovations include methods for creating hash tables that include specific uniform blocks, determining motion vector resolution based on hash-based block matching results, and detecting scene changes. These innovations also involve selecting long-term reference pictures and determining picture quality during encoding.

Original Abstract Submitted

Innovations in encoder-side decisions that use the results of hash-based block matching are presented. For example, some of the innovations relate to ways of building hash tables that include some (but not all) uniform blocks. Other innovations relate to ways of determining motion vector resolution based on results of hash-based block matching. Still other innovations relate to scene change detection, including long-term reference picture selection and picture quality determination during encoding.
