FIELD: physics, communications.SUBSTANCE: invention relates to video encoding techniques. Disclosed is a method of encoding input data to generate corresponding encoded output data. The method includes a step of dividing said input data into a plurality of blocks or packets, the size of which depends on the nature of the content thereof, wherein said blocks or packets have one or more sizes. Said input data are divided into a plurality of blocks or packets such that at least one of the representative parameters thereof, which describe content of said blocks or packets, are constant within the divided blocks or packets. Further, the method includes applying a plurality of transformations to the content of said blocks or packets to generate corresponding transformed data, and checking the quality of presentation of said transformed data of blocks or packets compared to the content of said blocks or packets before applying said transformations to determine if the quality of presentation of said transformed data satisfies one or more quality criteria.EFFECT: providing lossless data compression.23 cl, 6 dwg, 5 tbl |
