FIELD: computer equipment.
SUBSTANCE: invention relates to the field of computer equipment. Device comprises: information insertion unit, configured to: determine whether each data packet encapsulated in a transmission packet contains, the first identification information indicating that the data packet is to be processed with preferentially; set the first value for the second identification information in the transmission packet in case when it is determined that at least one data packet encapsulated in the transmission packet contains the first identification information, wherein the second identification information is established outside the data packet; the first value of the second identification information indicates the presence of the first identification information in the transmission packet; set the second value for the second identification information when it is determined that no data packet encapsulated in the transmission packet contains the first identification information; a transmission module configured to transmit a transmission stream with the second identification information set. Method describes operation of the device.
EFFECT: reducing the transmission time of the transmission stream.
