METHOD FOR HIGH DEFINITION VIDEO ENCODING/DECODING SUITABLE FOR REAL-TIME VIDEO STREAMING

摘要

A method is described for the encoding and decoding of digital video files in order to facilitate said files storage or transmission in bandwidth-sensitive applications. The method is based on the detection of regions of contrast within the video data and involves the generation of two compressed data sets, which when recombined yield a high quality representation of the original data. One of the compressed data sets is produced from the original data which has been reduced in resolution, while the remaining compressed data set is produced from a set of data representing areas of contrast in the original data.
