AI Technical Summary
In existing video coding technologies, the derivation methods of Rice parameters fail to effectively utilize historical information, leading to reduced coding efficiency. In particular, the coefficient estimation at the TU boundary is inaccurate, affecting the overall efficiency of video coding.
By synchronously updating the replacement variable HistValue and the history counter StatCoeff, the replacement variable is updated every time the history counter is updated, thereby improving the accuracy of the Rice parameter and the coding efficiency, and reducing the computational burden.
It improves the efficiency of video encoding, simplifies the calculation process, increases the processing speed of encoders and decoders, and improves encoding efficiency.
