Abstract
A data distribution method and apparatus have a satellite communication line (5) for transmitting data to a receiver and a ground line (10) for transmitting a data distribution request and a transmission confirmation pattern to a transmitter, a transmission confirmation designation device (11) in the transmitter for designating the transmission confirmation pattern, and a transmission confirmation processing device (12) for performing the transmission confirmation process according to a transmission confirmation method indicated by the transmitter.
Claims20
A data distribution method for performing data distribution between a transmitter and a receiver, comprising:
- detecting in the transmitter a data transmission confirmation pattern designation in a command option;
- selecting the content of a data transmission confirmation pattern by the transmitter, based on the detected data transmission confirmation pattern designation in the command option, the content of the data transmission confirmation pattern indicating at least one of an amount of data to be transmitted and a transmission time;
- inserting the content of the data transmission confirmation pattern into data to be transmitted, and transmitting the resulting data;
- and
- outputting a data transmission confirmation from the receiver to the transmitter according to the the content of the data transmission confirmation pattern received by the receiver.
A data distribution apparatus for transmitting data between a transmitter and a receiver, comprising:
- a transmission line device for receiving a distribution request of data in the transmitter,
- a memory device in the transmitter for storing the data,
- a control device in the transmitter for reading the data stored in the memory device and for controlling a data distribution operation to transmit the data to the receiver,
- a satellite transmission device for transmitting data controlled by the data distribution operation executed by the control device through radio waves,
- a satellite relay device for relaying the radio waves,
- a satellite receive device for receiving the radio waves,
- a control device in the receiver for receiving the radio waves received by the satellite receive device,
- a line device in the receiver, operatively connected to the line device in the transmitter, for transmitting a request and data to the transmitter,
- a data transmission confirmation designation device in the receiver for designating a data transmission confirmation pattern as the request;
- and
- a data transmission confirmation processing device in the receiver for receiving the content of the data transmission confirmation type and for performing a data transmission confirmation operation to the transmitter.
