Patent ID: 8842968

Claim:
A reproduction apparatus comprising: a packet number calculating portion that calculates a number of packets per unit time based on header information contained in an image and sound file; a reproduction start packet identifying portion that identifies, based on a number of packets per unit time, a reproduction start packet from which to start reproduction of image and sound; and a reproducing portion that starts reproduction of image and sound from the identified reproduction start packet, wherein the reproduction start packet identifying portion includes: a specified reproduction packet identifying portion that identifies, based on a number of packets per unit time, a specified reproduction packet corresponding to a specified reproduction time specified by a user; an extracting portion that extracts a reproduction time contained in from the specified reproduction packet; a deciding portion that decides whether or not the extracted reproduction time corresponds with the specified reproduction time specified by the user; a setting portion that, when the deciding portion decides that the extracted reproduction time corresponds with the specified reproduction time, sets the specified reproduction packet as the reproduction start packet; and a packet number correcting portion that, when the deciding portion decides that the extracted reproduction time does not coincide with the specified reproduction time, corrects the number of packets per unit time, wherein, when a difference between the extracted reproduction time and the specified reproduction time is larger than a first threshold value N, the packet number correcting portion decreases the number of packets per unit time.
