AI Technical Summary
In existing technologies, the coupling between the codec and the system layer is relatively large during video encoding and decoding, resulting in poor robustness of the encoding and decoding process. Furthermore, the transmission integrity of the knowledge base image bitstream cannot be guaranteed, affecting the stability and efficiency of encoding and decoding.
By encoding multiple display images and cross-RAR reference CRR images, an interleaved sorted encoded image bitstream is generated. Preset syntax identifiers, including quantity and position information, are added to the bitstream so that the decoder can determine whether all CRR image bitstream segments have been received. This decouples the encoder and the system layer and uses the CRR images as cross-RAP reference images to reduce temporal redundancy and bandwidth impact.
It improves the robustness of the encoding and decoding process, reduces bandwidth and decoder performance impact, reduces design and deployment costs, improves the applicability and compression efficiency of the encoding and decoding system, and enhances the stability of the encoding and decoding process.
