Method and device for dynamically monitoring the encoding of a digital multidimensional signal

A device for encoding an initial digital signal as an encoded signal, the device comprising:

• a processor;
• and
• a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
• performing, for current samples, localized encodings of the signal as encoded local digital signals, the encoded signal comprising the encoded local digital signals, wherein the initial digital signal comprises a sequence of samples representing a multidimensional space, each sample being assigned at least one physical quantity;
• performing an on-the-fly analysis of a characteristic associated with the encoded signal;
• and
• performing a direct or indirect adjustment at the sample level, of at least one encoding parameter involved in the localized encodings so as to stabilize the value of the characteristic on a target value to within a tolerance.

A non-transitory computer program product comprising a computer readable medium storing software code portions for execution of an encoding method comprising:

• performing, for at least some current samples, localized encodings of an initial signal as encoded local digital signals, an encoded signal comprising the encoded local digital signals, wherein the initial digital signal comprises a sequence of samples representing a multidimensional space, each sample being assigned at least one physical quantity;
• performing an on-the-fly analysis of a characteristic associated with the encoded signal;
• and
• performing a direct or indirect adjustment, at the sample level, of an encoding parameter involved in the localized encodings so as to stabilize a value of the characteristic on a target value to within a tolerance.
