• Section H: Electricity
• Class H04: Electric Communication Technique
• Subclass H04N: Pictorial Communication, e.g., Television
• Main Group H04N19/00: Methods or arrangements for coding, decoding, compressing, or decompressing digital video signals
• Subgroup H04N19/176: Involving predictive coding, specifically motion predictive coding

In this classification, H04N19/176 specifically relates to technologies, methods, or arrangements for coding, decoding, compressing, or decompressing digital video signals using predictive coding techniques, particularly motion predictive coding.

Predictive coding in video compression is a technique where frames are predicted based on past and/or future frames to reduce the amount of data needed to represent a video signal. This approach is fundamental in various video compression standards and is key to efficient video data transmission and storage. Motion predictive coding, a subset of this, focuses on predicting motion between frames to further optimize the compression of video data.

This classification is likely to encompass various innovations in the field of digital video processing, especially in areas related to efficient video compression and transmission, which are crucial in applications like streaming, broadcasting, and video conferencing.
