摘要： The present invention provides a multiplexing device, multiplexing method, and multiplexing program that allow an optional character string to be easily multiplexed with video online. The multiplexing processing unit multiplexes a dummy character string with the respective encoded data for video and audio. The multiplexed data are stored in the multiplexed data storage unit. The multiplexing processing unit stores the position (first dummy point) in which the dummy character string data were stored in the dummy point storage unit. The character string substitution processing unit substitutes the dummy character string data for the optional character string data to be inserted that has been input from the character string input unit on the basis of a first dummy point. The substituted multiplexed data are output as a multiplexed file from the file generation processing unit.

摘要： In a multicast distribution system in which terminal devices on a distribution path are hierarchically grouped, a first terminal device which has detected a loss of a receiving packet transmits to a second terminal device located upstream of the first terminal device a retransmission request for a packet retransmission to the first terminal device and a third terminal device which receives a packet first in a group located downstream of a group to which the first terminal device belongs. The second terminal device which has received the retransmission request transmits a retransmission packet to both the first and third terminal devices.

摘要： An apparatus for determining whether polygons which form objects defined by graphic data generated by CAD intersect with virtually generated light rays. Polygons which are not intersected are removed from the graphic data as unnecessary for the generation of CG data. An apparatus is also described in which path passage points which pass through an animation path within a virtual world are interactively set. If an object exists that interferes with a path that joins adjacent path passage points, an alternate route path which detours around the interfering object is generated. An apparatus is also described in which a path of a moving object is interactively set on a perspective view of the virtual world as viewed from one direction. The position of the set path in the virtual world is calculated, and the position of the path in the direction of viewing is corrected to a position that is removed from an object by a prescribed distance.
