Latest Patents

Su-Ren Chen holds a patent for a "Method and apparatus for MPEG-4 FGS performance enhancement." This invention features an architecture of a fine granularity scalable (FGS) codec that includes an encoder and a decoder configurable in three prediction modes. The encoder's coarse prediction loop has a switch for selecting either coarse or fine prediction output. Additionally, the enhancement layer of the encoder also has a switch for selecting prediction outputs. The invention employs two-pass encoding, where the first pass extracts coding parameters and classifies macroblocks of a video frame into three groups. The second pass utilizes these assigned modes to encode the macroblocks. A rate adaptation algorithm is included to efficiently allocate bits for achieving higher video quality across various bit rates.
