A data relay processing method where an available transmission band is partially reserved, partially assigned or partially exchanged between multiple communication terminals. Pieces of information are communicated between the multiple terminals. Such information includes a schedule of a term in which the transmission band is available, and a communication price that is charged to terminals in exchange for the usage of the transmission band. A schedule of transmission band usage and history of transmission band usage are utilized to efficiently reserve, assign or exchange the transmission band.

Data connecting method, data connecting apparatus, program recording medium

In order to control the coding quantity depending on the processing situation at the terminal when decoding or synthesizing plural pictures or sounds simultaneously, the decoding apparatus of the invention comprises a reception control unitfor receiving the information, a separation unitfor analyzing and separating the received information, a priority decision unitfor determining the priority of processing of the pictures separated in the separation unit, a picture expanding unitfor expanding the pictures according to the determined priority, s picture synthesizing unitfor synthesizing the pictures on the basis of the expanded pictures, a synthesis result accumulating unitfor accumulating the synthesized pictures, a reproduction time control unitfor controlling the time for starting reproduction, and an output unitfor delivering the result of synthesis according to the information of the reproduction time control unit

Picture and sound decoding apparatus picture and sound encoding apparatus and information transmission system

A data reception part for receiving data, a data transmission determination part for determining where the data should be transmitted according to, at least, the address written in the data, a data transmission part for transmitting data, and a transmission band management part for managing information on a transmission band. And an information drop method is characterized by having, as an input, contents to which the priority of the contents is added and processing where the contents are divided into packets of the Internet protocol and the priority of the contents is made to correspond to a priority field of packets of the Internet protocol, and said packets to which the priority is added are classified into drop classes having at least two or more different drop probabilities and said packets are dropped in accordance with the network load.

An image synthesis apparatus for synthesizing an image using model data including information which defines a three-dimensional structure for an object having a plurality of faces, original image data representing values of pixels respectively belonging to the plurality of faces, and rendering data for converting a three-dimensional image synthesized using the model data and the original image data into a two-dimensional image includes memory divided into a plurality of memory blocks each having a prescribed address unit for storing the model data, the original image data, the rendering data, and synthesized image data representing the synthesized two-dimensional image; an arbiter section including an address space, continuous addresses in the address space being allocated to different memory blocks from one another so as to interleave the addresses in the plurality of memory blocks; and a processor section including a plurality of processors each for accessing the memory means through the arbiter section to synthesize an image of one of the faces of the object based on a part of the model data corresponding to the one face, a part of the original image data corresponding to the one face, and a part of the rendering data corresponding to the one face. The original image data and the synthesized image data are each divided into a plurality of rectangular areas on a two-dimensional coordinate plane, and the plurality of rectangular areas are respectively allocated to the plurality of memory blocks.
