Data from Tianyancha reveals that on March 21, 2025, Vivo Mobile Communication Co., Ltd. was awarded a patent titled 'Video Encoding and Decoding Method, Video Encoder and Decoder, and Electronic Device', bearing the authorization announcement number CN114745552B. The patent application for this innovation was filed on April 27, 2022. Its primary objective is to boost encoding and decoding efficiency through the refinement of video frame encoding techniques.

The specific strategy is as follows: When encoding a sequence of video frames, if the current frame encompasses a region of interest (ROI) that corresponds to an area in the preceding frame, this region is bypassed during encoding as it is deemed redundant. The ROI in the prior frame undergoes lossless encoding. Subsequently, the matching ROI in the current frame simply reutilizes the encoding results from the previous frame. This cutting-edge technology has the potential to substantially curtail data volume and enhance the fluidity of video transmission and playback. It is especially well-suited for applications that demand high real-time performance, such as gaming and live streaming.
