<p>The quality of service in a digital television link (SME, LI, SMR) is surveyed cyclically by means of an analyzer (AM1 or AM2 or AM3) which analyzes the transport stream packets (TS) in order to determine a number of standardized analysis parameters which are complex to interpret. The invention minimizes the number of measurements of these parameters by selecting first and second analysis parameters in advance and periodically determining a first maximum for variations from the first selected parameters and the second maximum for variations from the second parameters selected in order to determine, respectively, a first parameter (SS) which is representative of the synchronization relative to the equipment in the link and at least one second parameter (TS; FD) which is representative of a degradation in a link.</p> |
