Patent ID: 7817569

Claim:
A method of receiving and recording a transport packet sequence on a recording medium by a recording device, comprising the steps of: extracting two pieces of program timing information, using the recording device, that are disposed within the transport packet sequence intermittently; calculating an average packet interval time using the recording device based on both a difference between the two pieces of program timing information and a number of packets between two packets where the pieces of two program timing information are extracted; and adding an arrival time to each packet, using the recording device, between the two packets and recording each packet tagged with the arrival time on a recording medium, wherein the arrival time of the each packet is determined by t(0)+I*t_av, where t_av is the calculated average packet interval time, t(0) is program timing information of a preceding packet among the two packets, and I is an index indicative of order of the each packet between the two packets where the two pieces of program timing information are extracted.
