Latest Patents

One of his latest patents is titled "Method and apparatus for video intermodal transcoding." This invention involves a video intermodal transcoder that converts a compressed bitstream formulated according to a type-1 compression scheme to a type-2 compressed bitstream. The transcoder includes an augmented type-1 decoder, a transcoder kernel, and an augmented type-2 encoder. The transcoder kernel performs processes of creating motion-vector candidates and pre-computing prediction errors for each cell of a predefined image coding block and for each candidate motion vector for repetitive use in evaluating various image partitions. In implementations where the type-1 compression scheme follows the H.264 standard and the type-2 compression scheme follows the HEVC standard, the transcoder exploits the flexibility of the coding-tree structure and other HEVC features to significantly reduce the bit rate of the compressed bit stream. The pre-computation of prediction errors significantly reduces the processing effort, hence increases the throughput of the transcoder.

Another significant patent is "System and method for quality-aware selection of parameters in transcoding of digital images." This invention describes several quality-aware transcoding systems and methods, considering the impact of both quality factor (QF) and scaling parameter choices on the quality of transcoded images. A basic transcoding system is enhanced by the addition of a quality prediction look-up table, and a method of generating such a table is also shown.
