Abstract
In a transport stream distribution system, a transmission rate control unit takes in an IP packet output from an IP transmission processing unit, obtains a TTS to be added to an arbitrary TS packet in the IP packet, and compares the TTS with a time stamp generated internally to determine whether both of them coincide with each other or not. And if they coincide with each other, the system takes in a TTS of the next TS packet, and otherwise, the system obtains a difference between a time indicating the TTS and the time indicating the internally generated time stamp to calculate a transmission rate correction value equivalent to the value of the difference, and issues the calculated correction value to the processing unit to correct a transmission rate.
