Latest Patents

One of Jianhua Chen's latest patents is a bit rate control method and device. This invention involves obtaining a bit rate control mode and coding control parameters for a current short period within a longer time frame. It determines a frame-level coding parameter for the current short period and transmits this parameter to an encoder. The device also performs statistical analysis on second bit stream information, which includes complexity information of the current video frame, the number of encoded bits, and coding quality information. This allows for efficient encoding of video frames in adjacent short periods while ensuring reasonable allocation of storage space without compromising image quality.

Another significant patent is related to systems, devices, and methods for video storage. This invention focuses on acquiring video data to generate buffer zone data, which begins with an I frame or an R frame of the video. The method involves storing part of the buffer zone data to a storage fragment and inserting an I Frame with reference to the first frame when certain conditions are met. This innovative approach enhances the efficiency of video storage systems.
