发明名称 Methods for transforming streaming video data
摘要 A method for forming an output stream of data includes determining an output resolution for the output stream of data, determining an output frame rate for the output stream of data, determining an output color depth for the output stream of data, retrieving a first frame of data, a second frame of data, and a third frame of data from an input stream of data, the input stream of data having an input resolution, an input frame rate, and an input color depth, subsampling the first frame of data, the second frame of data, and the third frame of data to respectively form a first subsampled frame of data, a second subsampled frame of data, and a third subsampled frame of data, when the output resolution is lower than the input resolution, dropping the second subsampled frame of data, when the output frame rate is lower than the input frame rate, reducing color depth for the first subsampled frame of data and the second subsampled frame of data to respectively form a first reduced frame of data and a second reduced frame of data, when the output color depth is smaller than the input color depth, and converting the first reduced frame of data and the second reduced frame of data into the output stream of data.
