Brief description of the compression of flow of clinical successively transmitted between a sender and receiver of a television and system for implementing the process

摘要

The process and the system for the compression of the flow of data between a sender and receiver of a television set out at the level of the sender a system of encoding differential 12 comprising a circuit 14, 15 for calculating and propagation of the cost of coding with respect to the thresholds of visibility for which a coding error becomes apparent on the image recue, the coding being carried out using at least two characteristics of quantification and or prediction various. A device 13 connects the system of encoding differential 12 transmits to the receiver, an indication of change of feature at the place of the database corresponding to the point of an image that must be transmitted when the point is located in an image area requiring this change. The clinical have of the codes whose length depends on the position of the points in the uniform zones or contour of the image. A device is provided at the level of the receiver, in order to reconstruct the database corresponding to the point which is not transmitted as a function of samples of fibers known to the receiver. / p & & p & application: transmission of television.
