Video coding method and apparatus

By splitting an image into sub-images and encoding and decoding them independently, the problem of high-resolution video not being processed in real time in a single encoder or decoder is solved. This achieves low-complexity video encoding and decoding in a multi-core architecture system and improves image quality.

AI Technical Summary

Technical Problem

Existing video codec systems cannot achieve real-time operation when processing high-resolution, high-frame-rate video in a single encoder or decoder, and the requirement for multi-core collaboration increases system complexity, making them unusable in systems without multi-core collaborative control.

Method used

The image to be encoded is split into multiple sub-images, which are then independently encoded by multiple encoders and merged into a single full-image compressed bitstream. During decoding, the single full-image compressed bitstream is split into multiple sub-image compressed bitstreams for independent decoding and then spliced ​​together to form the decoded full image, thus avoiding the need for multi-core collaboration.

Benefits of technology

This method reduces system complexity and maintains compatibility in multi-core architecture systems, while improving image quality through filtering. It is suitable for video encoding and decoding in multi-core architecture systems.

Abstract

The application provides a video coding method and device. The video coding method comprises: splitting a to-be-coded image to obtain a plurality of sub-images; obtaining a plurality of sub-image description information, wherein the plurality of sub-image description information corresponds to the plurality of sub-images, and the sub-image description information is used for describing the size and position of the corresponding sub-image; respectively coding the plurality of sub-images to obtain a plurality of sub-image compressed bit streams; and merging and transcribing the plurality of sub-image compressed bit streams to obtain a full-image compressed bit stream, wherein the full-image compressed bit stream comprises the plurality of sub-image description information. The application can be suitable for use in a multi-core architecture system, and can make the system-level complexity low and the compatibility stronger.
