The present invention provides an information processing apparatus which is a component of an information processing system in which real time data for which transmission and reception assurance within a predetermined period of time after every fixed period is necessary is communicated through an asynchronous network. The apparatus includes a generator and a transmission controller. The generator is configured to generate time synchronizing information, which is to be utilized upon setting of transmission and reception schedules of the real time data, as packets having a first region into which a sequence number which varies after every period of time corresponding to the fixed period is to be described. The transmission controller is configured to control the packets generated by the generator such that one packet is transmitted to the asynchronous network at each transmission timing after the fixed period.
