FIELD: engineering of data recording device, which makes it possible to control data even if data recorded on carrier are subjected to editing.
SUBSTANCE: first means for detecting on data recording device is meant for detecting information of supporting time for certain known data flow. First generating device is meant for generation of first discontinuous information, representing discontinuous characteristic of first time information, generated on basis of detection result, second discontinuous characteristic information, representing discontinuous characteristic of second time information, denoting packets receipt time, identification information for first array of packets, wherein gaps in noted first time information are absent as well as shift values for aforementioned identification information. onto data carrier aforementioned first discontinuous characteristic information is recorded, aforementioned second discontinuous characteristic information is recorded together with aforementioned shift value onto aforementioned information record carrier.
EFFECT: increased quality of data control and their reproduction when performing editing operations.
