Abstract

A transmitting apparatus includes a data dividing unit operable to divide data into pieces of transmittable data, a data outputting unit operable to add a distribution order to the divided pieces of transmittable data to form transmission data, and a transmitter operable to transmit the transmission data in different transmission paths simultaneously. As a result, the effects of using different transmission paths simultaneously and efficient transmission by a form of transmission corresponding to a state of communication are realized.

Claims

1. A transmitting apparatus, comprising:

a data dividing unit to divide data into pieces of data to be transmitted;

a data outputting unit to add a distribution order to the divided pieces of data to form transmission data;

a transmitter to transmit the transmission data in different transmission paths simultaneously; and

a response determining unit to determine a response to a previous data transmission in each of the different transmission paths,

wherein when the responses to previous data transmissions indicate that the transmission data in the previous data transmissions has failed to be received at least a predetermined number of times in one of the transmission paths, said data dividing unit divides the data such that there are no subsequent transmissions in the one transmission path.

2. A transmitting apparatus, comprising:

a data dividing unit to divide data into pieces of data to be transmitted;

a data outputting unit to add a distribution order to the divided pieces of data to form transmission data;

a transmitter to transmit the transmission data in different transmission paths simultaneously; and

a response determining unit to determine a response to a previous data transmission in each of the different transmission paths,

wherein when the responses to previous data transmissions indicate that the transmission data in the previous data transmissions has failed to be received at least a predetermined number of consecutive times in one of the transmission paths, said data dividing unit divides the data such that there are no subsequent transmissions in the one transmission path.

3. A transmitting apparatus, comprising:

a data dividing unit to divide data into pieces of data to be transmitted;

a data outputting unit to add a distribution order to the divided pieces of data to form transmission data;

a response determining unit to determine a response to a previous data transmission in each of the different transmission paths,

wherein when said response determining unit determines that the responses to previous data transmissions have successfully been received at least a predetermined number of times in one of the transmission paths, said data dividing unit divides the data such that subsequent transmissions are made in the one transmission path.

4. A transmitting apparatus, comprising:

a data dividing unit to divide data into pieces of data to be transmitted;
